Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

backlight: add S6E63M0 AMOLED LCD Panel driver This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI interface also almost features for lcd panel driver has been implemented in here. and I added new structure common for all the lcd panel drivers to include/linux/lcd.h file. LCD Panel driver needs interfaces for controlling device power such as power on/off and reset. these interfaces are device specific so it should be implemented to machine code at this time, we should create new structure for registering these functions as callbacks and also a header file for that structure and finally registered callback functions would be called by lcd panel driver. such header file(including new structure for lcd panel) would be added for all the lcd panel drivers. If anyone provides common structure for registering such callback functions then we could reduce unnecessary header files for lcd panel. I thought that suitable anyone could be include/linux/lcd.h so a new lcd_platform_data structure was added there.

atmel_lcdfb: backlight control On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from the LCD controller. It's controlled by "contrast" registers though. This patch lets boards declare that they have that kind of backlight control. The driver can then export this control, letting screenblank and other operations actually take effect ... reducing the typically substantial power drain from the backlight. Note that it's not fully cooked - doesn't force backlight off during system suspend - the "power" and "blank" events may not be done right This should be easily added in the future.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

backlight: add support for Pandora backlight 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.

backlight: Add TPS65217 WLED driver 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.

backlight: add an AS3711 PMIC backlight driver This is an initial commit of a backlight driver, using step-up DCDC power supplies on AS3711 PMIC. Only one mode has actually been tested, several further modes have been implemented "dry," but disabled to avoid accidental hardware damage. Anyone wishing to use any of those modes will have to modify the driver. Tested on sh73a0-based kzm9g board. Only one mode has been tested and is enabled. That mode copies the sample code from the manufacturer. Deviations from that code proved to be fatal for the hardware...
