driver:gpio remove all usage of gpio_remove retval in driver

2014-09-18T18:03:10+00:00

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.

drivers: leds: leds-tca6507: check CONFIG_GPIOLIB whether defined for 'gpio_base'

2014-01-28T01:28:49+00:00

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

The related error (with allmodconfig for metag):

    CC [M]  drivers/leds/leds-tca6507.o

LEDS: tca6507 - fix up some comments.

2014-01-28T01:28:47+00:00

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.

LEDS: tca6507: add device-tree support for GPIO configuration.

2014-01-28T01:28:46+00:00

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.

LEDS: tca6507 - fix bugs in parsing of device-tree configuration.

2014-01-28T01:28:42+00:00

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).

leds: use dev_get_platdata()

2013-08-27T00:22:11+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

leds: tca6507: Use of_match_ptr() macro

This eliminates having an #ifdef returning NULL for the case

leds: remove use of __devexit

2012-11-28T20:35:06+00:00

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.
