2015-08-28	leds: Export OF module alias information in missing drivers	Javier Martinez Canillas	1	-0/+1
	The I2C core always reports the MODALIAS uevent as "i2c:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: I2C id table or OF match table). So drivers needs to export the I2C id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added. But this means that OF-only drivers needs to have both OF and I2C id tables that have to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. Which can lead to issues if two vendors use the same I2C device name for example. To avoid the above, the I2C core behavior may be changed in the future to not require an SPI device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table even when is unused now to prevent breaking module loading when the core changes.

2015-08-28	leds: Drop owner assignment from i2c_driver	Krzysztof Kozlowski	1	-1/+0
	i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
2015-03-30	leds: pca963x: Add missing initialiation of struct led_info.flags	Geert Uytterhoeven	1	-1/+1
	Only the name and default_trigger fields are initialized. Other fields (currently flags only) contain random stack data. Pre-initialize the led structure completely to fix this. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Bryan Wu <cooloney@gmail.com>
2014-07-03	leds:pca963x: Always initialize MODE2 register	Peter Meerwald	1	-3/+7
	PCA9632 defaults to open-drain PCA9633/4/5 defaults to totem-pole the driver assumed that totem-pole default and didn't actively set the value; the MODE2 register is now written if platform data indicating the mode is given Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Bryan Wu <cooloney@gmail.com>
2014-07-03	leds:pca963x: Add support for PCA9635 LED driver chip	Peter Meerwald	1	-5/+13
	supports 16 PWM-controlled LEDs Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Bryan Wu <cooloney@gmail.com>
2013-08-26	leds-pca963x: Fix device tree parsing	Ricardo Ribalda Delgado	1	-4/+4
	A malformed device tree could lead into a segmentation fault if the reg value of a led is bigger than the number of leds. A valid device tree could have only information about the last led of the chip. Fix the device tree parsing to handle those cases.

2013-08-26	leds-pca9633: Rename to leds-pca963x	Ricardo Ribalda Delgado	1	-0/+461
	The driver now supports the chips pca9633 and pca9634, therefore we rename the files to more generic and meaningul names Signed-off-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
