Hi everyone,
This patch series is a 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.
I originally submitted this driver to MFD sybsystemd[mfdv1], but it
was suggested I add this driver to platform tree instead.
I suspect "bindings/mfd" is not the right place for bindings
information, but I wasn't sure if I should create "bindings/platform"
or "bindings/rave" to place that file into, so I left things as they
originally were hoping to fix this in next version of the patchset.
NOTE:
* The driver for "zii,rave-sp-watchdog" exists, but I haven't
submitted it yet, becuase I wanted to make sure that API exposed by
this MFD is acceptable and doesn't need drastic changes.
* This driver is dependent on crc_ccitt_false() introduced in
2da9378d531f8cc6670c7497f20d936b706ab80b in 'linux-next'
Feedback is greatly appreciated!
Thanks,
Andrey Smirnov

+Zodiac Inflight Innovations RAVE Supervisory Processor
+
+RAVE Supervisory Processor communicates with SoC over UART and is
+presented to the kernel as a "serdev". It is expected that its
+device-tree node is specified as a child of a node corresponding to
+UART controller used for communication.
+
+Required parent device properties:
+
+ - compatible: Should be one of:
+ - "zii,rave-sp-niu"
+ - "zii,rave-sp-mezz"
+ - "zii,rave-sp-esb"
+ - "zii,rave-sp-rdu1"
+ - "zii,rave-sp-rdu2"
+
+ - current-speed: Should be set to baud rate SP device is using
+
+RAVE SP consists of the following sub-devices:
+
+Device Description
+------ -----------
+rave-sp-wdt : Watchdog
+rave-sp-nvmem : Interface to onborad EEPROM
+rave-sp-backlight : Display backlight
+rave-sp-hwmon : Interface to onboard hardware sensors
+rave-sp-leds : Interface to onboard LEDs
+rave-sp-input : Interface to onboard power button
+
+Example of usage:
+
+ rdu {
+ compatible = "zii,rave-sp-rdu2";
+ current-speed = <1000000>;
+
+ watchdog {
+ compatible = "zii,rave-sp-watchdog";
+ };
+ };
