[PATCH v8 0/5] ZII RAVE platform driver

[Andrey Smirnov <andrew.smirnov-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hi everyone,

This patch series is v8 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 is dependent on crc_ccitt_false()
   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

 * Currently the driver is placed in drivers/platform instead of
   drivers/mfd as per request from Lee Jones (Lee, if you changed your
   mind about it, let me know and I'll move the driver back)


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
