[PATCH v12 0/5] ZII RAVE platform driver

[Andrey Smirnov]

Hi everyone,

This patch series is v12 of the driver for supervisory processor found
on RAVE series of devices from ZII. Supervisory processor is a PIC
microcontroller connected to various electrical subsystems on RAVE
devices whose firmware implements protocol to command/qery them.

NOTE:

 * This driver dependends on crc_ccitt_false(), added by
   2da9378d531f8cc6670c7497f20d936b706ab80b in 'linux-next', the patch
   was pulled in by Andrew Morton and is currently avaiting users, so
   this series might have to go in through Andrew's tree

Changes since [v11]:

    - Fix incorrect include in rave-sp-wdt.c as uncoverd by kernel
      test robot

Changes since [v10]:

    - Collected Acked-by from Rob and Reviewed-by from Guenter

    - Incorporated watchdog driver feedback from Gunter and Johan

    - Incorporated Johan's feedback for the rest of the code

Changes since [v9]:

    - Converted watchdog driver to use watchdog_active() instead of
      watchdog_hw_running() and replaced WARN_ON with a regular error
      message as per feedback from Guenter

    - Changed rave_sp_wdt_start() to set WDOG_HW_RUNNING only if
      communicating with hardware was sucessful

    - Collected Reviewd-by from Sebastian (for serdev related patches)

    - Collected Acked-by from Rob (for watchdog DT bindings)

Changes since [v8]:

    - Driver moved from drivers/platform to drivers/mfd

    - Collected Reviewed-by from Guenter (for patches 1, 2 and 3)

    - Incorporated feedback from Guenter into watchdog driver

    - Incorporated feedback from Rob into watchdog DT bindings

    - Removed struct rave_sp_rsp_status, which was a leftover from v5
      -> v6 code removal.

    - Fixed minor problems reported by checkpatch

Changes since [v7]:

    - Added watchdog driver to the patchset, so it would be easier to
      understand how parent/children drivers are tied together

    - Added serdev patches to implement devm_serdev_device_open() and make .remove optional

    - "Added" missing serdev_device_close() by converting the driver
      to use devm_serdev_device_open()

    - Converted the driver to use devm_of_platform_populate()

    - Removed needless dependency on MFD_CORE

    - Removed dependency on SERIAL_DEV_CTRL_TTYPORT

Changes since [v6]:

    - Patch 2/2 has been applied by Lee so it is no longer a part of the series

    - Removed all sysfs and debugfs attribute to reduce the scope of
      the driver propsed for inclusion. This is not a critical to have
      feature and can be added/discussed later.

Changes since [v5]:

    - Fixed a build break, introduced by a last minute change in [v5]

    - Moved majority of attributes that were exposed over sysfs to debugfs

    - Document remaining sysfs attributes in Documentation/ABI/testing/sysfs-platform-rave-sp

Changes since [v4]:

    - Replaced usage of DEVICE_ATTR with DEVICE_ATTR_RW

    - Fixed a number of warnings produces by sparse tool

    - Incorporated event more feedback from Andy Shevchenko

    - Collected Reviewed-by from Andy

Changes since [v3]:

    - Re-collected lost Acked-by from Rob

    - Incorporated further feedback from Andy Shevchenko

    - Dropped useless change (stray newline) to drivers/mfd/Makefile

Changes since [v2]:

    - Fixed swapped command codes in rave_sp_common_get_boot_source()
      and rave_sp_common_set_boot_source() revealed by further testing
      of the code

    - Incorporated feedback from Andy Shevchenko

Changes since [v1]:

    - Updated wording in DT-bindings as per Rob's request.

    - Collected Rob's Acked-by for patch 2/2

Feedback is greatly appreciated!

Thanks,
Andrey Smirnov
