backlight: add LM3533 backlight driver

2012-05-29T23:22:29Z

Add sub-driver for the backlights on National Semiconductor / TI LM3533 lighting power chips. The chip provides 256 brightness levels and ambient-light-sensor and pwm input control.

backlight: add driver for DA9052/53 PMIC v1

2012-04-05T22:25:51Z

DA9052/53 PMIC has capability to supply power for upto 3 banks of 6 white serial LEDS. It can also control intensity of independent banks and to drive these banks boost converter will provide up to 24V and forward current of max 50mA. This patch allows to control intensity of the individual WLEDs bank through DA9052/53 PMIC. This patch is functionally tested on Samsung SMDKV6410.

backlight: add support for Pandora backlight

2012-03-23T23:58:33Z

Add support for pandora (openpandora.org) backlight. It might look like all this could be done using pwm_bl.c instead, but there is a need of special programming sequence when turning on the LED driver chip or else it will misbehave. Doing this using pwm_bl.c would require to use some register programming and pwm functions from platform code, and ARM maintainers are allergic to driver-like code in /arch/arm nowadays. The PMIC PWM driver is currently missing too, so pwm_bl.c can't be used anyway. Signed-off-by: Grazvydas Ignotas Cc: Richard Purdie Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: add driver for Bachmann's ot200

2012-03-23T23:58:33Z

Add backlight driver for Bachmann's ot200 visualisation device. The driver uses MFGPT 7 of CS5535 silicon to regulate the backlight.

backlight: new backlight driver for LP855x devices

2012-03-23T23:58:33Z

THis driver supports TI LP8550/LP8551/LP8552/LP8553/LP8556 backlight devices. The brightness can be controlled by the I2C or PWM input. The lp855x driver provides both modes. For the PWM control, pwm-specific functions can be defined in the platform data. And some information can be read via the sysfs(lp855x device attributes). For details, please refer to Documentation/backlight/lp855x-driver.txt.

backlight: remove ADX backlight device support

2012-01-11T00:30:48Z

Support for the Avionic Design Xanthos backlight device got added in commit 3b96ea9ef8 ("backlight: Add support for the Avionic Design Xanthos backlight device."). That support depends on ARCH_PXA_ADX. The code that should have provided that Kconfig symbol never got submitted. It has never been possible to even build this driver. Remove it.
