Merge tag 'leds-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds 

Pull LED updates from Lee Jones:
 "New Drivers:
   - Add support for Intel Cherry Trail Whiskey Cove PMIC LEDs
   - Add support for Awinic AW20036/AW20054/AW20072 LEDs

  New Device Support:
   - Add support for PMI632 LPG to QCom LPG
   - Add support for PMI8998 to QCom Flash
   - Add support for MT6331, WLEDs and MT6332 to Mediatek MT6323 PMIC

  New Functionality:
   - Implement the LP55xx Charge Pump
   - Add support for suspend / resume to Intel Cherry Trail Whiskey Cove PMIC
   - Add support for breathing mode to Intel Cherry Trail Whiskey Cove PMIC
   - Enable per-pin resolution Pinctrl in LEDs GPIO

  Fix-ups:
   - Allow thread to sleep by switching from spinlock to mutex
   - Add lots of Device Tree bindings / support
   - Adapt relationships / dependencies driven by Kconfig
   - Switch I2C drivers from .probe_new() to .probe()
   - Remove superfluous / duplicate code
   - Replace strlcpy() with strscpy() for efficiency and overflow prevention
   - Staticify various functions
   - Trivial: Fixing coding style
   - Simplify / reduce code

  Bug Fixes:
   - Prevent NETDEV_LED_MODE_LINKUP from being cleared on rename
   - Repair race between led_set_brightness(LED_{OFF,FULL})
   - Fix Oops relating to sleeping in critical sections
   - Clear LED_INIT_DEFAULT_TRIGGER flag when clearing the current trigger
   - Do not leak resources in error handling paths
   - Fix unsigned comparison which can never be negative
   - Provide missing NULL terminating entries in tables
   - Fix misnaming issues"

description: |

  This controller is present on AW20036/AW20054/AW20072.

  It is a 3x12/6x9/6x12 matrix LED programmed via

  an I2C interface, up to 36/54/72 LEDs or 12/18/24 RGBs,

  3 pattern controllers for auto breathing or group dimming control.

        description: |

          Note that a driver will take the minimum of all LED limits

          since the chip has a single global setting.

          The maximum output current of each LED is calculated by the

          following formula:

            IMAXled = 160000 * (592 / 600.5) * (1 / display-rows)

          And the minimum output current formula:

            IMINled = 3300 * (592 / 600.5) * (1 / display-rows)
