[v5,00/12] leds: Fix/Add is31fl319{0,1,3} support

v5:
- added and tested Andy' series which converts driver to use
  device properties, dev_err_probe, devm_add_action_or_reset
  and simple i2c probe_new:
  https://lore.kernel.org/linux-leds/20220711213524.3587-1-andriy.shevchenko@linux.intel.com/

v4:
- took Andy's comments into account
- add patch 7 for cleanup and formatting fixes

v3:
- pick up Rob's R-b for patches 1 and 2
- reinstate bindings docs license and maintainer
  changes with Nikolaus agreement
- took Andy's comments on patch 4 into account

v2:
- keep original bindings license and maintainer/owner (Rob)
- squash bindings patches 2 & 4 (Krzysztof)

v1-resend:
- no change, resending after configuring git to accomodate
  for smtp provider limit of 5 emails per batch
- just change cover-letter to mention si-en chip for idol347


The is31fl3190, is31fl3191 and is31fl3193 chips (1 or 3 PWM channels)
cannot be handled the same as is31fl3196 and is31fl3199,
if only because the register map is different.
Also:
- the software shutdown bit is reversed
- and additional field needs to be set to enable all channels
- the led-max-microamp current values and setting are not the same

https://lumissil.com/assets/pdf/core/IS31FL3199_DS.pdf

This series:

- converts dt-bindings to dtschema, adding all si-en compatibles
  for convenience and consistency, and adding constraints on
  supported values for eg. reg address and led-max-microamp

- changes vars, structs and defines to not use 319X suffix
  but 3190 for 319{0,1,3} and 3196 for 319{6,9}

- adds fields in chipdef struct for chip-specific values

- only in patch 6, adds is31fl319{0,1,3} specific values
  so those chips can work.

- patch 7 cleanups parts non touched in previous patches

- patches 8 to 12 are Andy's to modernize the driver

Tested on msm8916-alcatel-idol347, which probably has an
si-en,sn3190 or si-en,sn3191 (only one white led indicator).

Andy Shevchenko (5):
  leds: is31fl319x: Make use of device properties
  leds: is31fl319x: Make use of dev_err_probe()
  leds: is31fl319x: Fix devm vs. non-devm ordering
  leds: is31fl319x: use simple i2c probe function
  leds: is31fl319x: sort header inclusion alphabetically

Vincent Knecht (7):
  dt-bindings: leds: Convert is31fl319x to dtschema
  dt-bindings: leds: is31fl319x: Document variants specificities
  leds: is31fl319x: Add missing si-en compatibles
  leds: is31fl319x: Use non-wildcard names for vars, structs and defines
  leds: is31fl319x: Move chipset-specific values in chipdef struct
  leds: is31fl319x: Add support for is31fl319{0,1,3} chips
  leds: is31fl319x: Cleanup formatting and dev_dbg calls

Hello !

Any chance getting this series merged for next/5.20 ?

Thank you
