2014-09-18driver:gpio remove all usage of gpio_remove retval in driverabdoulaye berthe1-5/+2
this remove all reference to gpio_remove retval in all driver except pinctrl and gpio. the same thing is done for gpio and pinctrl in two different patches.

'gpio_base' Need check CONFIG_GPIOLIB whether defined, just like another area has done within this file. Or can not pass compiling when CONFIG_GPIOLIB disabled.

2014-01-27LEDS: tca6507 - fix up some comments.NeilBrown1-88/+102
In particular fix the capitalisation of GPIO and LED and correct TCA6507_MAKE_CPIO, but also rewrite the comment about platform-data to include reference to devicetree. Also re-wrap comments to fit 80 columns. Reported-by: Bryan Wu <cooloney@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Bryan Wu <cooloney@gmail.com>
2014-01-27LEDS: tca6507: add device-tree support for GPIO configuration.NeilBrown1-0/+6
The 7 lines driven by the TCA6507 can either drive LEDs or act as output-only GPIOs. To make this distinction in devicetree we use the "compatible" property. If the device attached to a line is "compatible" with "gpio", we treat it like a GPIO. If it is "compatible" with "led" (or if no "compatible" value is set) we treat it like an LED.

2014-01-27LEDS: tca6507 - fix bugs in parsing of device-tree configuration.NeilBrown1-4/+4
1/ The led_info array must be allocated to allow the full number of LEDs even if not all are present. The array maybe be sparsely filled but it is indexed by device address so we must at least allocate as many slots as the highest address used. It is easiest just to allocate all 7. 2/ range check the 'reg' value properly. 3/ led.flags must be initialised to zero, else all leds could be treated as GPIOs (depending on what happens to be on the stack).

2012-03-23drivers/leds/leds-tca6507.c: cleanup error handling in tca6507_probe()Dan Carpenter1-5/+3
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.

2012-01-10leds: add driver for TCA6507 LED controllerNeilBrown1-0/+779
TI's TCA6507 is the LED driver in the GTA04 Openmoko motherboard. The driver provides full support for brightness levels and hardware blinking. This driver can drive each of 7 outputs as an LED or a GPIO output, and provides hardware-assist blinking.
