Fix checkpatch.pl when both -q and --ignore are given and prevents it from printing a NOTE: Ignored message types: blah messages. E.g., if I use -q --ignore PREFER_PACKED,PREFER_ALIGNED, i see: NOTE: Ignored message types: PREFER_ALIGNED PREFER_PACKED It makes no sense to print this when -q is given.

Argument alignment across multiple lines should match the open parenthesis. Logical continuations should be at the end of the previous line, not the start of a new line. These are not required by CodingStyle so make the tests active only when using --strict. Improved by some examples from Bruce Allen. Signed-off-by: Joe Perches <joe@perches.com> Cc: "Bruce W.

- Generate a 64-bit pattern more efficiently memchr_inv needs to generate a 64-bit pattern filled with a target character. The operation can be done by more efficient way. - Don't call the slow check_bytes() if the memory area is 64-bit aligned memchr_inv compares contiguous 64-bit words with the 64-bit pattern as much as possible. The outside of the region is checked by check_bytes() that scans for each byte. Unfortunately, the first 64-bit word is unexpectedly scanned by check_bytes() even if the memory area is aligned to a 64-bit boundary. Both changes were originally suggested by Eric Dumazet.

* add 'struct lm3530_pwm_data' in the platform data The pwm data is the platform specific functions which generate the pwm. The pwm data is only valid when brightness is pwm input mode. Functions should be implemented by the pwm driver. pwm_set_intensity() : set duty of pwm. pwm_get_intensity() : get current the brightness. * brightness control by pwm If the control mode is pwm, then brightness is changed by the duty of pwm=. So pwm platform function should be called in lm3530_brightness_set(). * do not update brightness register when pwm input mode In pwm input mode, brightness register is not used. If any value is updated in this register, then the led will be off. * when input mode is changed, set duty of pwm to 0 if unnecessary.

Only 7 bits are used for updating the brightness. (register address : A0h) So the max_brightness property of lm3530 should be set to 127. On initializing registers, maximum initial brightness is limited to 'max_brightness'. Division-by-two is removed on updating the brightness. This arithmetic is not necessary because the range of brightness is 0 ~ 127= .

The lp5521 has autonomous operation mode without external control. Using lp5521_platform_data, various led patterns can be configurable. For supporting this feature, new functions and device attribute are added. Structure of lp5521_led_pattern: 3 channels are supported - red, green and blue. Pattern(s) of each channel and numbers of pattern(s) are defined in the pla= tform data. Pattern data are hexa codes which include pattern commands such like set pwm, wait, ramp up/down, branch and so on. Pattern mode functions: * lp5521_clear_program_memory Before running new led pattern, program memory should be cleared. * lp5521_write_program_memory Pattern data updated in the program memory via the i2c. * lp5521_get_pattern Get pattern from predefined in the platform data. * lp5521_run_led_pattern Stop current pattern or run new pattern. Transition time is required between different operation mode. Device attribute - 'led_pattern': To load specific led pattern, new device attribute is added. When the lp5521 driver is unloaded, stop current led pattern mode. Documentation updated : description about how to define the led patterns and example.

Just a small tidy-up. 1) There is a NULL dereference if the tca allocation fails. 2) The call to cancel_work_sync() isn't needed because we haven't scheduled any work. 3) The call to i2c_set_clientdata() isn't needed because the core handles that automatically if probe() fails. 4) I added some curly braces for style reasons.

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.

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.
