[PATCH V8 0/4] Add Anbernic RG Vita-Pro

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Add support for the Anbernic RG Vita-Pro, based on the Rockchip RK3576 SoC.

Changes Since V1:
 - Updated documentation filename to matche compatible string.
 - Corrected order of allocating IRQ in charger driver and switched
   to using devm managed function to allocate work queue.
Changes Since V2:
 - Corrected issue with naming of panel binding document and added
   fallback compatible string.
 - Switched to devm helpers in panel driver. Note that
   devm_drm_panel_add() is currently only in the drm-next branch.
 - Optimized setting GPIOs for panel driver.
Changes Since V3:
 - Fixed numerous issues identifed by Sashiko bot, mainly relating
   to unclamped or improperly clamped values from within the
   charger driver.
 - Corrected hard-coded values in the panel driver unprepare routine
   as well as correcting an improperly checked return condition.
Changes Since V4:
 - Fixed errors identified by Sashiko bot on charger driver that could
   result in an improper value being written to the registers.
 - Corrected some error handling in the panel driver.
Changes Since V5:
 - Corrected minor errors in documentation and added default values.
 - Further corrected clamping behavior in charger driver.
Changes Since V6:
 - Additional corrections as suggested by Sashiko bot to fix potential
   edge cases during probe for sgm41542.
 - Corrected an improperly shifted value being written to register for
   sgm41542.
 - Changed a MV value to UV in sgm41542 driver to simplify function.
Changes Since V7:
 - Added PM functions to sgm41542 driver per request from Sashiko,
   which stops the hardware watchdog during suspend.
 - Switched from device_init_wakeup() to devm_device_init_wakeup().
 - Confirmed a state change in IRQ handler for sgm41542 to ensure we
   don't update input current limit except when the vbus goes from
   not okay to okay.
 - Removed panel patches, which have already been accepted upstream.
   Please note that this *may* cause an error about missing bindings.
   See commit 0fd6ead8270270d859a28d0196a4b47e7d6845b8 in linux-next.
