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
