edd7b6b9be mailbox: bcm-flexrm-mailbox: Fix FlexRM ring flush timeout issue
[ Upstream commit d7bf31a0f85faaf63c63c39d55154825a1eaaea9 ]

RING_CONTROL reg was not written due to wrong address, hence all
the subsequent ring flush was timing out.

6ae7336a4e mailbox: msm_qmp: Wait for link up in mbox_startup
There is a chance a client probe can start before the link is
established with the remote processor. Add a wait for link up in the
mailbox startup to prevent extra probe deferrrals for clients.

commit afd0b1fb22269f48d68fdf269891c653818c8047 upstream.

acpi_pcc_probe() calls acpi_table_parse_entries_array() but fails
to check for an error return.  This in turn can result in calling
kcalloc() with a negative count as well as emitting the following
misleading erorr message:

623a6143a8 mailbox: mediatek: Add Mediatek CMDQ driver
This patch is first version of Mediatek Command Queue(CMDQ) driver. The
CMDQ is used to help write registers with critical time limitation,
such as updating display configuration during the vblank. It controls
Global Command Engine (GCE) hardware to achieve this requirement.
Currently, CMDQ only supports display related hardwares, but we expect
it can be extended to other hardwares for future requirements.

a2b79838b8 mailbox: ti-msgmgr: Add support for Secure Proxy
Secure Proxy is another communication scheme in Texas Instrument's
devices intended to provide an unique communication path from various
processors in the System on Chip(SoC) to a central System Controller.

Secure proxy is, in effect, an evolution of current generation Message
Manager hardware block found in K2G devices. However the following
changes have taken place:

Secure Proxy instance exposes "threads" or "proxies" which is
primary representation of "a" communication channel. Each thread is
preconfigured by System controller configuration based on SoC usage
requirements. Secure proxy by itself represents a single "queue" of
communication but allows the proxies to be independently operated.

Each Secure proxy thread can uniquely have their own error and threshold
interrupts allowing for more fine control of IRQ handling.

Provide the driver support for Secure Proxy and thread instances.

NOTE: Secure proxy configuration is only done by System Controller,
hence these are assumed to be pre-configured instances.

5ab935e194 mailbox: ti-msgmgr: Allocate Rx channel resources only on request
In a much bigger system SoCs, the number of Rx channels can be
many and mostly unused based on the system of choice, and not all
Rx channels need IRQs and allocating all memory at probe will be
inefficient. Some SoCs could have total threads in the 100s and usage
would be just 1 Rx thread.

Thus, request and map the IRQs and allocate memory only when needed.

Since these channels are requested by client drivers on need, our
utilization will be optimal.

match data for distinguishing the interrupt register layout
between OMAP2 and OMAP4+ SoCs. Introduce a dedicated structure
for storing this match data, and simplify the probe function by
using the of_device_get_match_data() function. This allows the
driver to scale for 64-bit platforms by eliminating the unnecessary
type-casting between a u32 and a void pointer types.

3512a18cbd mailbox: xgene-slimpro: Fix potential NULL pointer dereference
There is a potential execution path in which function
platform_get_resource() returns NULL. If this happens,
we will end up having a NULL pointer dereference.

Fix this by replacing devm_ioremap with devm_ioremap_resource,
which has the NULL check and the memory region request.

This code was detected with the help of Coccinelle.

a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

f83d1cfc8b mailbox/drivers/hisi: Consolidate the Kconfig for the MAILBOX
The current defconfig is inconsistent as it selects the mailbox and
the clock for the hi6220 and the hi3660 without having their Kconfigs
making sure the dependencies are correct. It ends up when selecting
different versions for the kernel (for example when git bisecting)
those options disappear and they don't get back, leading to unexpected
behaviors. In our case, the cpufreq driver does no longer work because
the clock fails to initialize due to the clock stub and the mailbox
missing.

In order to have the dependencies correctly set when defaulting, let's
do the same as commit 3a49afb84c ("clk: enable hi655x common clk
automatically") where we select automatically the driver when the
parent driver is selected. With sensible defaults in place, we can leave
other choices for EXPERT.

19ed70c0b3 mailbox: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

8f8027c5f9 mailbox: PCC: erroneous error message when parsing ACPI PCCT
There have been multiple reports of the following error message:

[    0.068293] Error parsing PCC subspaces from PCCT

This error message is not correct.  In multiple cases examined, the PCCT
(Platform Communications Channel Table) concerned is actually properly
constructed; the problem is that acpi_pcc_probe() which reads the PCCT
is making the assumption that the only valid PCCT is one that contains
subtables of one of two types: ACPI_PCCT_TYPE_HW_REDUCED_SUBSPACE or
ACPI_PCCT_TYPE_HW_REDUCED_TYPE2.  The number of subtables of these
types are counted and as long as there is at least one of the desired
types, the acpi_pcc_probe() succeeds.  When no subtables of these types
are found, regardless of whether or not any other subtable types are
present, the error mentioned above is reported.

In the cases reported to me personally, the PCCT contains exactly one
subtable of type ACPI_PCCT_TYPE_GENERIC_SUBSPACE.  The function
acpi_pcc_probe() does not count it as a valid subtable, so believes
there to be no valid subtables, and hence outputs the error message.

An example of the PCCT being reported as erroneous yet perfectly fine
is the following:

                    Signature : "PCCT"

          Maximum Access Rate : 00000000
      Minimum Turnaround Time : 0000

To fix this, we count up all of the possible subtable types for the
PCCT, and only report an error when there are none (which could mean
either no subtables, or no valid subtables), or there are too many.
We also change the logic so that if there is a valid subtable, we
do try to initialize it per the PCCT subtable contents.  This is a
change in functionality; previously, the probe would have returned
right after the error message and would not have tried to use any
other subtable definition.

Tested on my personal laptop which showed the error previously; the
error message no longer appears and the laptop appears to operate
normally.

41c0e939d7 mailbox: Add support for Hi3660 mailbox
Hi3660 mailbox controller is used to send message within multiple
processors, MCU, HIFI, etc.  It supports 32 mailbox channels and every
channel can only be used for single transferring direction.  Once the
channel is enabled, it needs to specify the destination interrupt and
acknowledge interrupt, these two interrupt vectors are used to create
the connection between the mailbox and interrupt controllers.

The data transferring supports two modes, one is named as "automatic
acknowledge" mode so after send message the kernel doesn't need to wait
for acknowledge from remote and directly return; there have another mode
is to rely on handling interrupt for acknowledge.

This commit is for initial version driver, which only supports
"automatic acknowledge" mode to support CPU clock, which is the only
one consumer to use mailbox and has been verified.  Later may enhance
this driver for interrupt mode (e.g. for supporting HIFI).

a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

Currently the mailbox framework sets txdone_method to TXDONE_BY_POLL if
the controller sets txdone_by_poll. However some clients can have a
mechanism to do TXDONE_BY_ACK which they can specify by knows_txdone.
However, we endup setting both TXDONE_BY_POLL and TXDONE_BY_ACK in that
case. In such scenario, we may end up with below warnings as the tx
ticker is run both by mailbox framework and the client.

Merge tag 'acpi-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These update ACPICA to upstream revision 20170831, fix APEI to use the
  fixmap instead of ioremap_page_range(), add an operation region driver
  for TI PMIC TPS68470, add support for PCC subspace IDs to the ACPI
  CPPC driver, fix a few assorted issues and clean up some code.

  Specifics:

   - Update the ACPICA code to upstream revision 20170831 including
      * PDTT table header support (Bob Moore).
      * Cleanup and extension of internal string-to-integer conversion
        functions (Bob Moore).
      * Support for 64-bit hardware accesses (Lv Zheng).
      * ACPI PM Timer code adjustment to deal with 64-bit return values
        of acpi_hw_read() (Bob Moore).
      * Support for deferred table verification in acpiexec (Lv Zheng).

   - Fix APEI to use the fixmap instead of ioremap_page_range() which
     cannot work correctly the way the code in there attempted to use it
     and drop some code that's not necessary any more after that change
     (James Morse).

   - Clean up the APEI support code and make it use 64-bit timestamps
     (Arnd Bergmann, Dongjiu Geng, Jan Beulich).

   - Add operation region driver for TI PMIC TPS68470 (Rajmohan Mani).

   - Add support for PCC subspace IDs to the ACPI CPPC driver (George
     Cherian).

   - Fix an ACPI EC driver regression related to the handling of EC
     events during the "noirq" phases of system suspend/resume (Lv
     Zheng).

   - Delay the initialization of the lid state in the ACPI button driver
     to fix issues appearing on some systems (Hans de Goede).

   - Extend the KIOX000A "device always present" quirk to cover all
     affected BIOS versions (Hans de Goede).

   - Clean up some code in the ACPI core and drivers (Colin Ian King,
     Gustavo Silva)"

Pull timer updates from Thomas Gleixner:
 "Yet another big pile of changes:

   - More year 2038 work from Arnd slowly reaching the point where we
     need to think about the syscalls themself.

   - A new timer function which allows to conditionally (re)arm a timer
     only when it's either not running or the new expiry time is sooner
     than the armed expiry time. This allows to use a single timer for
     multiple timeout requirements w/o caring about the first expiry
     time at the call site.

   - A new NMI safe accessor to clock real time for the printk timestamp
     work. Can be used by tracing, perf as well if required.

   - A large number of timer setup conversions from Kees which got
     collected here because either maintainers requested so or they
     simply got ignored. As Kees pointed out already there are a few
     trivial merge conflicts and some redundant commits which was
     unavoidable due to the size of this conversion effort.

   - Avoid a redundant iteration in the timer wheel softirq processing.

   - Provide a mechanism to treat RTC implementations depending on their
     hardware properties, i.e. don't inflict the write at the 0.5
     seconds boundary which originates from the PC CMOS RTC to all RTCs.
     No functional change as drivers need to be updated separately.

   - The usual small updates to core code clocksource drivers. Nothing
     really exciting"

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.
