cb95c169e9 clk: mediatek: Fix corner case of tuner_en_reg
On MT8195, tuner_en_reg is moved to register offest 0x0.
If we only judge by tuner_en_reg, it may lead to wrong address.
Add tuner_en_bit to the check condition. And it has been confirmed,
on all the MediaTek SoCs, bit0 of offset 0x0 is always occupied by
clock square control.

6d26bb22e9 clk: qcom: mmcc-msm8998: Remove unnecessary fallbacks to global clocks
A previous patch removes the "xo" clock from the global namespace making
it impossible to acquire by that ".name".  The device-tree for msm8998
currently does not include an mmcc node but the dt-bindings for this
compatible already require all these clocks, and the patch introducing
this node [1] also includes them.

Some of these clocks are not referenced by the driver at all whereas
aud_ref_clk and core_bi_pll_test_se are but were missing from the
bindings.  These clocks are optional (and not currently provided
anywhere) while "xo" and "sleep_clk" are mandatory.

Note that none of these clocks were used beforehand as the driver
referenced them by their global name.

Now that all clock controllers and the DSI PLL clocks rely on "xo" being

e815e34b6b clk: qcom: gcc-msm8998: Use parent_data/hws for internal clock relations
Use parent_data and parent_hws to specify internal relations using
pointers instead of names, and use .fw_name to retrieve external clocks
from clock-names in the DT rather than the global clock tree.

Note that this change relies on the "xo" and "sleep_clk" clocks to be
provided in DT, as per the relevant qcom,gcc-mnsm8998.yaml dt-bindings.
These clocks have been added in a prior patch [1].

dt-bindings: clocks: Fix typo in the H6 compatible
Even though both the driver and the device trees all use the
allwinner,sun50i-h6-de3-clk, we documented the compatible as
allwinner,sun50i-h6-de2-clk in the binding. Let's fix this.

clk: sunxi-ng: Use a separate lock for each CCU instance
Some platforms have more than one CCU driver loaded: the main CCU, the
PRCM, the display engine, and possibly others. All of these hardware
blocks have separate MMIO spaces, so there is no need to synchronize
between them.

clk: sunxi-ng: Prevent unbinding CCUs via sysfs
The CCU drivers are not really designed to be unbound. Unbinding a SoC's
main CCU is especially pointless, as very few of the peripherals on the
SoC will work without it. Let's avoid any potential problems by removing
the bind/unbind attributes from sysfs for these drivers.

This change is not applied to the "secondary" CCUs (DE, USB) as those
could reasonably be unbound without making the system useless.

clk: sunxi-ng: Unregister clocks/resets when unbinding
Currently, unbinding a CCU driver unmaps the device's MMIO region, while
leaving its clocks/resets and their providers registered. This can cause
a page fault later when some clock operation tries to perform MMIO. Fix
this by separating the CCU initialization from the memory allocation,
and then using a devres callback to unregister the clocks and resets.

This also fixes a memory leak of the `struct ccu_reset`, and uses the
correct owner (the specific platform driver) for the clocks and resets.

Early OF clock providers are never unregistered, and limited error
handling is possible, so they are mostly unchanged. The error reporting
is made more consistent by moving the message inside of_sunxi_ccu_probe.

clk: sunxi-ng: Add machine dependency to A83T CCU
The CCUs for all other 32-bit SoCs have a dependency on a specific
MACH_SUNxI symbol. This effectively hides these drivers when building
an ARCH=arm64 kernel. However, the A83T CCU still shows up because it
is missing this dependency. Let's add it for consistency.
