Support for requesting the next power_off operation for a genpd to be
synchronous is introduced, and implemented in the GDSC driver. To allow
the GPU driver to request power_off to wait for the GDSC to actually
collapse.
Support for QDU1000/QRU1000 Global clock controller, SA8775P Global
clock controller, SM8550 TCSR and display clock controller, SM6350 clock
controller, nd MSM8996 CBF and APCS clock controllers is introduced.
Parent references are updated across a large number of clock drivers, to
align with the design changes since those drivers where introduced.
Similarly, test clocks has been dropped from a range of drivers.
A range of fixes for the MSM8996 CPU clock controller is introduced.
MSM8974 GCC is transitioned off the externally defined sleep_clk.
GDSC in the global clock controller for QCS404 is added, and various
parent definitions are cleaned up.
The SDCC core clocks on SM6115 are moved for floor_ops.
Programming of clk_dis_wait for GPU CX GDSC on SC7180 and SDM845 are
moved to use the recently introduced properties in the GDSC struct.
The RPMh clock driver gains SM8550 and SA8775P clocks, and the IPA clock
is added on a variety of platforms.
The SMD RPM driver receives a big cleanup, in particular a move away
from duplicating declaration of identical clocks between multiple
platforms.
A few missing clocks across msm8998, msm8992, msm8916, qcs404 are added
as well.
Using devm_pm_runtime_enable() to clean up some duplication is done
across SM8250 display and video clock controllers, SM8450 display clock
controller and SC7280 LPASS clock controller.
Devicetree binding changes for above mentioned additions and changes are
introduced.
Support for postponing clk_disable_unused() until sync_state was
introduced, but later reverted again, awaiting an agreement on the
solution.
Lastly, a change to pad a few registers in the SM8250 DTS to 8 digits
was picked up in the wrong tree and kept here, to avoid rebasing.

clk: ralink: fix 'mt7621_gate_is_enabled()' function
Compiling clock driver with CONFIG_UBSAN enabled shows the following trace:
UBSAN: shift-out-of-bounds in drivers/clk/ralink/clk-mt7621.c:121:15
shift exponent 131072 is too large for 32-bit type 'long unsigned int'
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.15.86 #0
Stack : ...
Shifting a value (131032) larger than the type (32 bit unsigned integer)
is undefined behaviour in C.
The problem is in 'mt7621_gate_is_enabled()' function which is using the
'BIT()' kernel macro with the bit index for the clock gate to check if the
bit is set. When the clock gates structure is created driver is already
setting 'bit_idx' using 'BIT()' macro, so we are wrongly applying an extra
'BIT()' mask here. Removing it solve the problem and makes this function
correct. However when clock gating is correctly working, the kernel starts
disabling those clocks that are not requested. Some drivers for this SoC
are older than this clock driver itself. So to avoid the kernel to disable
clocks that have been enabled until now, we must apply 'CLK_IS_CRITICAL'
flag on gates initialization code.
Export the necessary symbols from the core clk driver and add the
license and author tags. To find this type of problem more easily
in the future, also enable building on other platforms, as we do for
the other i.MX clk drivers.

clk: Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled()
In the previous commits that added CLK_OPS_PARENT_ENABLE, support for
this flag was only added to rate change operations (rate setting and
reparent) and disabling unused subtree. It was not added to the
clock gate related operations. Any hardware driver that needs it for
these operations will either see bogus results, or worse, hang.
This has been seen on MT8192 and MT8195, where the imp_ii2_* clk
drivers set this, but dumping debugfs clk_summary would cause it
to hang.
Prepare parent on prepare and enable parent on enable dependencies are
already handled automatically by the core as part of its sequencing.
Whether the case for "enable parent on prepare" should be supported by
this flag or not is not clear, and thus ignored for now.
This change solely fixes the handling of clk_core_is_enabled, i.e.
enabling the parent clock when reading the hardware state. Unfortunately
clk_core_is_enabled is called in a variety of places, sometimes with
the enable clock already held. To avoid deadlocking, the core will
ignore readouts and just return false if CLK_OPS_PARENT_ENABLE is set
but the parent isn't currently enabled.

clk: mediatek: clk-gate: Propagate struct device with mtk_clk_register_gates()
Commit e4c23e19aa2a ("clk: mediatek: Register clock gate with device")
introduces a helper function for the sole purpose of propagating a
struct device pointer to the clk API when registering the mtk-gate
clocks to take advantage of Runtime PM when/where needed and where
a power domain is defined in devicetree.
Function mtk_clk_register_gates() then becomes a wrapper around the
new mtk_clk_register_gates_with_dev() function that will simply pass
NULL as struct device: this is essential when registering drivers
with CLK_OF_DECLARE instead of as a platform device, as there will
be no struct device to pass... but we can as well simply have only
one function that always takes such pointer as a param and pass NULL
when unavoidable.
This commit removes the mtk_clk_register_gates() wrapper and renames
mtk_clk_register_gates_with_dev() to the former and all of the calls
to either of the two functions were fixed in all drivers in order to
reflect this change; also, to improve consistency with other kernel
functions, the pointer to struct device was moved as the first param.
Since a lot of MediaTek clock drivers are actually registering as a
platform device, but were still registering the mtk-gate clocks
without passing any struct device to the clock framework, they've
been changed to pass a valid one now, as to make all those platforms
able to use runtime power management where available.
While at it, some much needed indentation changes were also done.
