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"

+
+/sys/class/leds/<led>/hw_pattern
+--------------------------------
+
+Specify a hardware pattern for the Whiskey Cove PMIC LEDs.
+
+The only supported pattern is hardware breathing mode::
+
+    "0 2000 1 2000"
+
+	^
+	|
+    Max-|     ---
+	|    /   \
+	|   /     \
+	|  /       \     /
+	| /         \   /
+    Min-|-           ---
+	|
+	0------2------4--> time (sec)
+
+The rise and fall times must be the same value.
+Supported values are 2000, 1000, 500 and 250 for
+breathing frequencies of 1/4, 1/2, 1 and 2 Hz.
+
+The set pattern only controls the timing. For max brightness the last
+set brightness is used and the max brightness can be changed
+while breathing by writing the brightness attribute.
+
+This is just like how blinking works in the LED subsystem,
+for both sw and hw blinking the brightness can also be changed
+while blinking. Breathing on this hw really is just a variant
+mode of blinking.
