leds: Add driver for Acer Iconia Tab A500

2020-09-26T19:56:42+00:00

Acer Iconia Tab A500 is an Android tablet device which has two LEDs
embedded into the Power Button. Orange LED indicates "battery charging"
status and white LED indicates "wake-up/charge-done" status. The new LED
driver provides control over both LEDs to userspace.

This driver can be compiled on other platforms with small change if
COMPILE_TEST=y.

leds: lp50xx: Add the LP50XX family of the RGB LED driver

2020-08-17T20:33:18+00:00

Introduce the LP5036/30/24/18/12/9 RGB LED driver.
The difference in these parts are the number of
LED outputs where the:

LP5036 can control 36 LEDs
LP5030 can control 30 LEDs
LP5024 can control 24 LEDs
LP5018 can control 18 LEDs
LP5012 can control 12 LEDs
LP5009 can control 9 LEDs

The device has the ability to group LED outputs into control banks
so that multiple LED banks can be controlled with the same mixing and
brightness. Or the LED outputs can also be controlled independently.

leds: LP55XX_COMMON needs to depend on LEDS_CLASS

2020-08-17T20:28:36+00:00

With these kernel configs:
CONFIG_LEDS_CLASS=m
# CONFIG_LEDS_CLASS_MULTICOLOR is not set
CONFIG_LEDS_LP55XX_COMMON=y
CONFIG_LEDS_LP5521=m
CONFIG_LEDS_LP5562=m

leds-lp55xx-common.c has a build error because it is builtin and
calls an interface that is built as a loadable module (due to
LEDS_CLASS=m). By making LEDS_LP55XX_COMMON depend on LEDS_CLASS,
this config combination cannot happen, thus preventing the build error.

ld: drivers/leds/leds-lp55xx-common.o: in function `lp55xx_register_leds':
leds-lp55xx-common.c:(.text+0xc5f): undefined reference to `devm_led_classdev_register_ext'

Make LEDS_LP55XX_COMMON depend on I2C to fix build errors:

2020-07-28T10:26:13+00:00

leds-lp55xx-common.c:(.text+0x9d): undefined reference to `i2c_smbus_read_byte_data'
leds-lp55xx-common.c:(.text+0x8fc): undefined reference to `i2c_smbus_write_byte_data'

These errors happened when I2C=m and LEDS_LP55XX_COMMON=y, so
prevent that from being possible.

leds: initial support for Turris Omnia LEDs

2020-07-24T10:58:55+00:00

This adds basic support for LEDs on the front side of CZ.NIC's Turris
Omnia router.

There are 12 RGB LEDs. The controller supports HW triggering mode for
the LEDs, but this driver does not support it yet, and sets all the LEDs
defined in device-tree into SW mode upon probe.

This driver uses the multicolor LED framework.

leds: multicolor: Introduce a multicolor class definition

2020-07-22T12:41:29+00:00

Introduce a multicolor class that groups colored LEDs
within a LED node.

The multicolor class groups monochrome LEDs and allows controlling two
aspects of the final combined color: hue and lightness. The former is
controlled via the intensity file and the latter is controlled
via brightness file.
