[U-Boot] [PATCH 1/7] mtd: Fix function description in part_validate comment

[Otavio Salvador]

The part_validate comment had a wrong description of the actions it
does and referenced to non-existent functions while in fact it calls
'part_validate_eraseblock()'.

[U-Boot] [PATCH 5/7] gpio-led: Fix __led_toggle support to first set GPIO as input

[Otavio Salvador]

The GPIO need to be set as input before reading its current value and
set back to output for setting it; this fixes the non-working
'led <id> toggle' for GPIO based LEDs.

How can that work on a hardware point of view ?
If you configure the gpio as an input it isn't any more driven as an
output so the value you read depends on the way the led is wired (and
maybe also on internal pull up/down) and not on the way it was
previously driven when the gpio was an output.

Maybe the real fix would be to check why gpio_get_value doesn't return
the level of the gpio when it's configured as an output.

There is already a STATUS_LED_ACTIVE definition (though not one per LED) in
include/status_led.h for some platforms. Wouldn't it be worth keeping the same
naming here for consistency (i.e. STATUS_LED_ACTIVEn, which would also imply
exchanging 0/1 values)?

I agree. "INVERT" is confusing, because we don't know what is the normal state.

Doing like Beno?t suggests would be clearer: STATUS_LED_ACTIVE0 or
STATUS_LED_ACTIVE1.

The problem here is that the BIT LEDs are used in the cmd_led and it
does not have the 'active' knowledge but a ON OFF concept. So what we
do there is to change the intended status. The STATUS_LED_ACTIVE is
for the STATUS_LED_BOOT and not for a 'specific' bit.

I meant that the current use of STATUS_LED_ACTIVE could be extended to what you
are trying to do here:
+#ifndef STATUS_LED_ACTIVE
+#define STATUS_LED_ACTIVE 1
+#endif
+#ifndef STATUS_LED_ACTIVE1
+#define STATUS_LED_ACTIVE1 1
+#endif
+#ifndef STATUS_LED_ACTIVE2
+#define STATUS_LED_ACTIVE2 1
+#endif
+#ifndef STATUS_LED_ACTIVE3
+#define STATUS_LED_ACTIVE3 1
+#endif

But then, maybe it's not the call to __led_set() that should be changed, but
rather how the passed value is used in the underlying layer, e.g. in
drivers/misc/gpio_led.c. However, since the status LED API takes binary states,
it better fits in drivers/misc/status_led.c as you did.

That means that __led_set() would no longer take STATUS_LED_ON/OFF, but rather
something like STATUS_LED_HI/LO, and led_state_value() would convert
STATUS_LED_ON/OFF to STATUS_LED_HI/LO according to STATUS_LED_ACTIVEn.
