backlight: ili9320: add missing SPI dependency

2012-10-25T21:37:52Z

Add this missing SPI dependency and prevent the driver from building without SPI, because functions of the spi driver are used in this driver. drivers/video/backlight/ili9320.c:51: undefined reference to `spi_sync' Also, a prompt string for CONFIG_LCD_ILI9320 is added for explicit selection.

backlight: remove ProGear driver

2012-10-05T18:04:53Z

This driver was for the ProGear webpad device which was produced in 2000/2001 and is not available on a market. I no longer have this hardware so can not even check how Linux works on it. Signed-off-by: Marcin Juszkiewicz Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: add new lm3639 backlight driver

2012-10-05T18:04:53Z

This driver is a general version for LM3639 backlgiht + flash driver chip of TI. LM3639: The LM3639 is a single chip LCD Display Backlight driver + white LED Camera driver.

backlight: add Backlight driver for lm3630 chip

2012-10-05T18:04:53Z

This driver is a general version for LM3630 backlgiht driver chip of TI. LM3630 : The LM3630 is a current mode boost converter which supplies the power and controls the current in two strings of up to 10 LEDs per string. Programming is done over an I2C compatible interface. www.ti.com [akpm@linux-foundation.org: make bled_name[] static, a few coding style tuneups, create new set_intensity(), partly to avoid awkward layout gymnastics] Signed-off-by: G.Shark Jeong Cc: Richard Purdie Cc: Daniel Jeong Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

backlight: Add TPS65217 WLED driver

2012-09-25T08:42:02Z

The TPS65217 chip contains a boost converter and current sinks which can be used to drive LEDs for use as backlights. Expose this functionality via the backlight API. Tested on an AM335x based custom board with a single WLED string, using different values for ISEL and FDIM (though it would be hard to tell the difference except for the value in WLEDCTRL1). Both instantiation through the device tree and by passing platform data have been tested. Testing has been done with an Androidized 3.2 kernel from the rowboat project. Koen Kooi reported the driver to be working on a Beaglebone board with LCD3 cape Signed-off-by: Matthias Kaehlcke Signed-off-by: Samuel Ortiz

Merge branch 'for-3.6' of git://gitorious.org/linux-pwm/linux-pwm

2012-07-30T16:22:37Z

Pull PWM subsystem from Thierry Reding: "The new PWM subsystem aims at collecting all implementations of the legacy PWM API and to eventually replace it completely. The subsystem has been in development for over half a year now and many drivers have already been converted. It has been in linux-next for a couple of weeks and there have been no major issues so I think it is ready for inclusion in your tree." Arnd Bergmann : "Very much Ack on the new subsystem. It uses the interface declarations as the previously separate pwm drivers, so nothing changes for now in the drivers using it, although it enables us to change those more easily in the future if we want to. This work is also one of the missing pieces that are required to eventually build ARM kernels for multiple platforms, which is currently prohibited (amongs other things) by the fact that you cannot have more than one driver exporting the pwm functions."

pwm-backlight: Add rudimentary device tree support

2012-07-23T11:23:52Z

This commit adds very basic support for device tree probing. Currently, only a PWM and a list of distinct brightness levels can be specified. Enabling or disabling backlight power via GPIOs is not yet supported. Reviewed-by: Shawn Guo Reviewed-by: Mark Brown Signed-off-by: Thierry Reding
