as3645a: Unregister indicator LED on device unbind

2017-09-23T19:17:43+00:00

The indicator LED was registered in probe but was not removed in driver
remove callback. Fix this.

as3645a: Use integer numbers for parsing LEDs

2017-09-23T19:17:12+00:00

Use integer numbers for LEDs, 0 is the flash and 1 is the indicator.

as3645a: Use ams,input-max-microamp as documented in DT bindings

2017-09-23T19:16:42+00:00

DT bindings document the property "ams,input-max-microamp" that limits the
chip's maximum input current. The driver and the DTS however used
"peak-current-limit" property. Fix this by using the property documented
in DT binding documentation.

dmi: Mark all struct dmi_system_id instances const

... and __initconst if applicable.

Based on similar work for an older kernel in the Grsecurity patch.

Pull LED updates from Jacek Anaszewski:
 "LED class drivers improvements:

  leds-pca955x:
   - add Device Tree support and bindings
   - use devm_led_classdev_register()
   - add GPIO support
   - prevent crippled LED class device name
   - check for I2C errors

  leds-gpio:
   - add optional retain-state-shutdown DT property
   - allow LED to retain state at shutdown

  leds-tlc591xx:
   - merge conditional tests
   - add missing of_node_put

  leds-powernv:
   - delete an error message for a failed memory allocation in
     powernv_led_create()

  leds-is31fl32xx.c
   - convert to using custom %pOF printf format specifier

  Constify attribute_group structures in:
   - leds-blinkm
   - leds-lm3533

  Make several arrays static const in:
   - leds-aat1290
   - leds-lp5521
   - leds-lp5562
   - leds-lp8501"

media: leds: as3645a: add V4L2_FLASH_LED_CLASS dependency

2017-09-05T20:32:45+00:00

We get a link error when V4L2_FLASH_LED_CLASS=m and AS3645A is built-in:

drivers/leds/leds-as3645a.o: In function `as3645a_v4l2_setup':
leds-as3645a.c:(.text+0x258): undefined reference to `v4l2_flash_init'
leds-as3645a.c:(.text+0x284): undefined reference to `v4l2_flash_indicator_init'

drivers/leds/leds-as3645a.o: In function `as3645a_remove':
leds-as3645a.c:(.text+0x784): undefined reference to `v4l2_flash_release'

This adds the same Kconfig dependency that the other V4L2 flash
drivers in drivers/leds use, to avoid that broken configuration.

leds: gpio: Allow LED to retain state at shutdown

2017-08-29T19:10:40+00:00

In some systems, such as Baseboard Management Controllers (BMCs), we
want to retain the state of LEDs across a reboot of the BMC (whilst the
host remains up). Implement support for the retain-state-shutdown
devicetree property in leds-gpio.
