6e7df1d151 global: Finish CONFIG -> CFG migration
At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

2d8d190c83 status_led: Kconfig migration
Move all of the status LED feature to drivers/led/Kconfig.
The LED status definitions were moved from the board configuration
files to the defconfig files.

TBD: Move all of the definitions in the include/status_led.h to the
relevant board's defconfig files.

Tested boards: CL-SOM-AM57x, CM-T335

d375ebbcb6 add generic stubs for GPIO LEDs
For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED),
it may be useful to have some generic stubs (wrapper functions)
for the "colored" LEDs.

This allows defining STATUS_LED_* values directly to GPIO numbers,
e.g.: #define STATUS_LED_GREEN	248 /* = PH24 */

To keep those optional, it's probably best to introduce an additional
configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that.
Placing the code in drivers/misc/gpio_led.c also ensures that it
automatically depends on CONFIG_GPIO_LED too.

9dfdcdfed4 gpio_led: add support for inverted polarity
Some GPIO connected LEDs have inverted polarity.
Introduce new config option: CONFIG_GPIO_LED_INVERTED_TABLE for the
specifying the inverted GPIO LEDs list and add support for this in the
gpio_led driver.

6516f81b64 gpio_led: check gpio_request() return value
Add a check for the gpio_request() function return value and do not try
to configure the GPIO if the gpio_request() call fails.
Also, print an error message indicating the gpio_request() has failed.

ec3b498192 gpio_led: add gpio_request to __led_init
This patch adds the gpio usage request. The polarity is changed to
positive as suggested by Mike Frysinger.

3e6b86b555 misc: add gpio based status led driver
This patch adds a status led driver followed the GPIO access
conventions of Linux. The led mask is used to specify the gpio pin.
