Don't rely on the programmer to enter the name of array elements, since the computer can compute it with much less chance of making a mistake. Signed-off-by:

Add compatible for the RPM Clock Controller on the QCM2290 SoC. Signed-off-by:

Shawn Guo authored
As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can be used by branch clocks to report rate as well, rather than assuming the rate is always same as parent clock. This assumption doesn't hold on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is 19.2MHz. To get this work, XO buffered clocks need the following updates. - Assign a correct rate rather than the fake one which is being used to generate binary value for clk_smd_rpm_req interface. - Explicitly handle the clk_smd_rpm_req interface value for XO buffered clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).

Add Global Clock Controller (GCC) driver for QCM2290. This is a porting of gcc-scuba driver from CAF msm-4.19, with GDSC support added on top. Because the alpha_pll on the platform has a different register layout (offsets), its own clk_alpha_pll_regs_offset[] is used in the driver. Signed-off-by:

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.

A previous patch removes the "xo" clock from the global namespace making it impossible to acquire by that ".name". The device-tree for msm8998 already provides the "xo" and "gpll0" clock since the addition of the gpucc node making it unnecessary to have this fallback at all. Reviewed-by:

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. Signed-off-by:

Now that all clock controllers and the DSI PLL clocks rely on "xo" being passed in DT as phandle instead of looking it up by the global "xo" name this transient clock can be removed, leaving only the fixed-factor "xo_board" clock in DT. Reviewed-by:

Marijn Suijten authored
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].

Prepare for a future patch where we use .hw pointers to these GPLL clocks in the parent mapping instead of name references. This requires the GPLL clocks to be decared before parent_data arrays. Reviewed-by:
