b9fe89a100 clk: qcom: gpucc: Constify 'struct qcom_cc_desc'
'struct qcom_cc_desc' is passed to qcom_cc_map() and
qcom_cc_really_probe() only as pointer to const, so make the memory
const for safety.

9f93a0a428 clk: qcom: common: commonize qcom_cc_really_probe
The previous wrapper qcom_cc_really_probe takes the platform
device as parameter, which is limited to platform driver.

As for qca8k clock controller driver, which is registered as
the MDIO device, which also follows the qcom clock framework.

To commonize qcom_cc_really_probe, updating it to take the
struct device as parameter, so that the qcom_cc_really_probe
can be utilized by the previous platform device and the new
added MDIO device.

Also update the current clock controller drivers to take
&pdev->dev as parameter when calling qcom_cc_really_probe.

d09ec6f987 clk: qcom: Use qcom_branch_set_clk_en()
Instead of magically poking at the bit0 of branch clocks' CBCR, use
the newly introduced helper.

deebc79b28 clk: qcom: gpucc-sc8280xp: Add external supply for GX gdsc
On SA8295P and SA8540P the GFX rail is powered by a dedicated external
regulator, instead of the rpmh-controlled "gfx.lvl".

Define the "vdd-gfx" as the supply regulator for the GDSC, to cause the
gdsc logic to look for, and control, this external power supply.

9bbcb892a7 clk: qcom: gpucc-sc8280xp: Add runtime PM
The GPU_CC block on SC8280XP is powered by the GFX rail. We need to
ensure that it's enabled to prevent unwanted power collapse.

Enable runtime PM to keep the power flowing only when necessary.
