* Fix version recognition in elantech_set_properties
The new hardware reports itself as v7 but the packets'
structure is unaltered.
* Fix packet type recognition in elantech_packet_check_v4
The bitmask used for v6 is too wide, only the last three bits of
the third byte in a packet (packet[3] & 0x03) are actually used to
distinguish between packet types.
Starting from v7, additional information (to be interpreted) is
stored in the remaining bits (packets[3] & 0x1c).
In addition, the value stored in (packet[0] & 0x0c) is no longer
a constant but contains additional information yet to be deciphered.
This change should be backwards compatible with v6 hardware.

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT

firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.
Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse

Merge tag 'am335x_tsc-adc' of git://breakpoint.cc/bigeasy/linux
A complete refurbished series inclunding:
- DT support for the MFD, TSC and ADC driver & platform device support,
which has no users, has been killed.
- iio_map from last series is gone and replaced by proper nodes in the
device tree.
- suspend fixes which means correct data structs are taken and no
interrupt storm
- fifo split which should problem with TSC & ADC beeing used at the same
time
- The ADC channels are now checked before blindly applied. That means the
touch part reads X, Y and Z coordinates and does not mix them up. Same

- The IIO ADC driver now creates files named in_voltageX_raw where X
represents the ADC line instead of a number starting at 0. A read from
this file can return -EBUSY in case touch is busy and the ADC didn't
collect a value.
The previous patch ("input/ti_am335x_tsc: ACK the HW_PEN irq in ISR")
acked the interrupt so we don't freeze if we don't handle an enabled
interrupt source. The interrupt core has a mechanism for this and to get
it work one should only say that it handled an interrupt if it is
actually the case.
Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
The interrupt source IRQENB_HW_PEN is enabled in suspend and suposed to
be used as a wake up source. Once this interrupt source is unmaksed, the
devices ends up in ISR and never continues.
This change ACKs the interrupt and disables it so the system does not
freeze.
Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
The driver programs a threshold of "coordinate_readouts" say 5. The
REG_FIFO0THR registers says it should it be programmed to "threshold
minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2.
Multiplied by two because 5 for X and 5 for Y and plus 2 because we have
two Z.
The whole thing kind of works because It reads the 5 coordinates for X
and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored
within the loop and read later.
Nothing guaranties that FIFO1 is ready by the time it is read. In fact I
could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for
Y channel 7 for Z. The problem is that channel 7 and channel 12 got
somehow mixed up.
The other Problem is that FIFO1 is also used by the IIO part leading to
wrong results if both (tsc & adc) are used.
The patch tries to clean up the whole thing a little:
- Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter
part in the for loop. This is just confusing.
- Use only FIFO0 in TSC. The fifo has space for 64 entries so should be
fine.
- Read the whole FIFO in one function and check the channel.
- in case we dawdle around, make sure we only read a multiple of our
coordinate set. On the second interrupt we will cleanup the remaining
enties.

Current code has hard coded value written to
step enable bits. Now the bits are updated based
on how many steps are needed to be configured got
from platform data.
The user needs to take care not to exceed
the count more than 16. While using ADC and TSC
one should take care to set this parameter correctly.
Sebastian added the common lock and moved the code, that manipulates the
steps, from into the mfd module.
