The given operations are inverted for the wrong registers which makes
multiple of the mt8365 hardware units unusable. In my setup at least usb
did not work.
Fixed by swapping the operations with the inverted ones.

Before the patch [1], the clock probe was done directly in the
clk-mt8365 driver. In this probe function, the array which stores the
data clocks is sized using the higher defined numbers (*_NR_CLOCK) in
the clock lists [2]. Currently, with the patch [1], the specific
clk-mt8365 probe function is replaced by the mtk generic one [3], which
size the clock data array by adding all the clock descriptor array size
provided by the clk-mt8365 driver.
Actually, all clock indexes come from the header file [2], that mean, if
there are more clock (then more index) in the header file [2] than the
number of clock declared in the clock descriptor arrays (which is the
case currently), the clock data array will be undersized and then the
generic probe function will overflow when it will try to write in
"clk_data[CLK_INDEX]". Actually, instead of crashing at boot, the probe
function returns an error in the log which looks like:
"of_clk_hw_onecell_get: invalid index 135", then this clock isn't
enabled.
Solve this issue by adding in the driver the missing clocks declared in
the header clock file [2].

[sboyd@kernel.org: Also unmap on error]
Signed-off-by: Stephen Boyd <sboyd@kernel.org>
Convert the MT8135 clock drivers to platform_driver using the common
simple probe mechanism; special note goes to the introduction of
dummy clocks with ID 0 (where 0 is the first entry of a clock array)
for each clock controller: this was necessary because of a mistake
in the bindings for all MT8135 clock controllers, where the first
clock has ID 1 (hence, array would start from element 1) instead of
zero.
Now that all of the MT8135 clock drivers (including apmixedsys) can
be compiled as modules, change the COMMON_CLK_MT8135 configuration
option to tristate to enable module build.
While at it, also remove the __initconst annotation from all of the
clock arrays as they are not only used during init anymore, but also
during runtime.

Also, since the need for "clk-mt8192-simple" and "clk-mt8192" was
just due to them being in the same file and probing different clocks,
and since now there's just one platform_driver struct per file, it
seemed natural to rename the `-simple` variant to just "clk-mt8192".

non critical clocks as tristate.
As a note, the dependencies of VDEC/VENCSYS and CAM/IMG/IPE/WPESYS
are not for build-time but rather for runtime, as clocks registered
by those have runtime dependencies on either or both VPP and IMGSYS.

Convert this driver to use the common mtk_clk_simple_probe() mechanism.
While at it, also remove __initconst annotations (as these structures
are used also at runtime).

Convert this driver to use the common mtk_clk_simple_probe() mechanism.
While at it, also use module_platform_driver() instead, as this driver
just gained a .remove() callback during the conversion.

Instead of calling clk_prepare_enable() at probe time, add the PLL_AO
flag to CLK_APMIXED_ARMPLL clock: this will set CLK_IS_CRITICAL.
