clk: qcom: Revert sync_state based clk_disable_unused

2023-02-22T14:34:08+00:00

Revert the postponement of clk_disable_unused() for clock providers that
implement sync_state, and the change to drivers implementing this, until
agreement on the implementation has been reached.

This reverts:

clk: qcom: gpucc-sdm845: fix clk_dis_wait being programmed for CX GDSC

2023-02-09T01:48:55+00:00

The gdsc_init() function will rewrite the CLK_DIS_WAIT field while
registering the GDSC (writing the value 0x2 by default). This will
override the setting done in the driver's probe function.

Set cx_gdsc.clk_dis_wait_val to 8 to follow the intention of the probe
function.

clk: qcom: add msm8996 Core Bus Framework (CBF) support

2023-02-09T00:12:29+00:00

Add CBF clock driver as a part of MSM8996 CPU clocks. Significantly
based on AngeloGioacchino del Regno's work at [1].

The CBF is an interconnect between two CPU clusters, setting it up
properly is required for booting the MSM8996 with all four cores
enabled.

clk: qcom: add the driver for the MSM8996 APCS clocks

2023-02-08T22:31:52+00:00

Add a simple driver handling the APCS clocks on MSM8996. For now it
supports just a single aux clock, linking GPLL0 to CPU and CBF clocks.

Note, there is little sense in registering sys_apcs_aux as a child of
gpll0. The PLL is always-on. And listing the gpll0 as a property of the
apcs would delay its probing until the GCC has been probed (while we
would like for the apcs to be probed as early as possible).
