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!
