[PATCH] gpio: mvebu: change compatible string for PWM support

[PATCH] gpio: mvebu: change compatible string for PWM support

[Ralph Sennhauser]

As it turns out more than just Armada 370 and XP support using GPIO
lines as PWM lines. For example the Armada 38x family has the same
hardware support. As such "marvell,armada-370-xp-gpio" for the
compatible string is a misnomer.

Change the compatible string to "marvell,armada-370-gpio" before the
driver makes it out of the -rc stage. This also follows the practice of
using only the first device family supported as part of the name.

Also update the documentation and comments in the code accordingly.

Hi everyone,

The suggestion to change the compatible string last minute comes from
Gregory CLEMENT after we realized the bad choice of name due to Richard
Genoud reporting an issue when he used the driver with an Armada-388.

Rob Herring just requested to use a separate compatible string but not
what it should look like. So I assume he is fine with the new one as
well. The rest of this patch is rather minor.

Nothing in tree is using this driver so far, first consumers will be
added with 4.13.

You mean for fixes right ?
The goal was to correct "marvell,armada-370-xp-gpio" before 4.12 is out.

Hi Linus,

As Richard already correctly pointed out this needs to go into 4.12 as
we can't really change the compatible string after 4.12 final was
released. So this commit was pushed to the wrong branch. Sorry for
not having been more explicit in my wording.

Thanks
Ralph
