CSR_INT_COALESCING previously had only one, but now has two single-byte fields. With only one single-byte field (lowest order byte) it was okay to write via iwl_write32(), but now with two, an iwl_write32() to the lower order field clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the next-higher register (CSR_INT, offset 0x8). Fortunately, no bad side effects have been produced by the iwl_write32() usage, due to order of execution (low order byte was always written before higher order byte), and the fact that writing "0" to the low byte of the next higher register has no effect (only action is when writing "1"s). Nonetheless, this cleans up the accesses so no bad side effects might occur in the future, if execution order changes, or more bit fields get added to CSR_INT_COALESCING. Add some comments regarding periodic interrupt usage. Signed-off-by: Ben Cahill <ben.m.cahill@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* CSR (control and status registers)
|

*
|
|
* CSR registers are mapped directly into PCI bus space, and are accessible
|
|
* whenever platform supplies power to device, even when device is in
|
|
* low power states due to driver-invoked device resets
|
|
* (e.g. CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes.

* Use iwl_write32() and iwl_read32() family to access these registers;
|
|
* these provide simple PCI bus access, without waking up the MAC.
|
|
* Do not use iwl_write_direct32() family for these registers;
|
|
* no need to "grab nic access" via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ.
|
|
* The MAC (uCode processor, etc.) does not need to be powered up for accessing
|
|
* the CSR registers.
|
|
*
|
|
* NOTE: Newer devices using one-time-programmable (OTP) memory
|

|
|
* Host sets this to request permanent halt of uCode, same as
|
|
* sending CARD_STATE command with "halt" bit set.
|
|
* 3: CT_KILL_EXIT
|
|
* Host sets this to request exit from CT_KILL state, i.e. host thinks
|
|
* device temperature is low enough to continue normal operation.
|
|
* 2: CMD_BLOCKED
|
|
* Host sets this during RF KILL power-down sequence (HW, SW, CT KILL)
|
|
* to release uCode to clear all Tx and command queues, enter
|
|
* unassociated mode, and power down.
|
|
* NOTE: Some devices also use HBUS_TARG_MBX_C register for this bit.
|
|
* 1: SW_BIT_RFKILL
|
|
* Host sets this when issuing CARD_STATE command to request
|
|
* device sleep.
|
|
* 0: MAC_SLEEP
|
|
* uCode sets this when preparing a power-saving power-down.
|
|
* uCode resets this when power-up is complete and SRAM is sane.
|
|
* NOTE: 3945/4965 saves internal SRAM data to host when powering down,
|
|
* and must restore this data after powering back up.
|
|
* MAC_SLEEP is the best indication that restore is complete.
|
|
* Later devices (5xxx/6xxx/1xxx) use non-volatile SRAM, and
|
|
* do not need to save/restore it.
