commit 89c7f5078935872cf47a713a645affb5037be694 upstream
This does not matter the least, but there is no other .[ch] file in the
repo that is executable, so clean this up.

In commit 91419ae0420f ("arm64: dts: rockchip: use BCLK to GPIO switch
on rk3399"), an additional pinctrl state was added whose default pinmux
is for 8ch i2s0. However, Puma only has 2ch i2s0. It's been overriding
the pinctrl-0 property but the second property override was missed in
the aforementioned commit.
On Puma, a hardware slider called "BIOS Disable/Normal Boot" can disable
eMMC and SPI to force booting from SD card. Another software-controlled
GPIO is then configured to override this behavior to make eMMC and SPI
available without human intervention. This is currently done in U-Boot
and it was enough until the aforementioned commit.
Indeed, because of this additional not-yet-overridden property, this
software-controlled GPIO is now muxed in a state that does not override
this hardware slider anymore, rendering SPI and eMMC flashes unusable.
Let's override the property with the 2ch pinmux to fix this.
While at it, add a GPIO hog for this software-controlled GPIO to make it
explicit and also make it reserve the pin through the pinctrl subsystem
to make sure nobody can mistakenly request it for something else: better
have a non-working feature than eMMC/SPI being corrupted "randomly"!

In _set_opp() we are normally bailing out when trying to set an OPP that is
the current one. This make perfect sense, but becomes a problem when
_set_required_opps() calls it recursively.
More precisely, when a required OPP is being shared by multiple PM domains,
we end up skipping to request the corresponding performance-state for all
of the PM domains, but the first one. Let's fix the problem, by calling
_set_opp_level() from _set_required_opps() instead.
