[PATCHv7] ARM: exynos_defconfig: Enable LEDS for Odroid-XU3/XU4

[Anand Moon]

Earlier design of the LED for Odroid XU3 was using gpio-leds
Now It was change to using both pwm-leds and gpio-leds.

It is still not a reason for this change. gpio-leds were not enabled
before. This could be a valid reason of adding LEDS_PWM to existing
config LEDS_GPIO. But LEDS_GPIO were not enabled... so why the change on
the board from gpio->(gpio+pwm) means that we have to enable LEDS_GPIO?

Actually I gave up on this and I wanted to change the commit message on
myself when applying. But discussion was brought up again so... clearly
we have different understanding of the meaning of "WHY". :)

Best regards,
Krzysztof

Agreed, also the commit message doesn't explain why the heartbeat
LED trigger is enabled as I mentioned in the previous version.

Just of the records. I you agree with following commit message I will
resend the patch.
------------------------------------------------------
Exynos boards support GPIO and PWM based LEDs

Odroid boards support led activity to indicate the various status
Red led - power: hooked up to 5V power
Blue led - alive Solid light : u-boot is running
               flashing : Kernel is running (heart beat)
-------------------------------------------------------
If you want to add some thing more please suggest me.

Earlier I was just frustrated.

That commit message looks better. Anyway I applied the patch with
changed message. You can find it here:
https://github.com/krzk/linux/commit/8b14e57ae423b676873e542944ed8714be211ded

although it is not pushed to the for-next branch because we are at merge
window.

Best regards,
Krzysztof
