2021-09-23clk: meson: meson8b: Make the video clock trees mutableMartin Blumenstingl1-38/+38
Switch from the "_ro" clock op variants to the mutable ones for all video clocks. This will allow the VPU driver to change the clocks as needed for the different video output modes.

2021-09-23clk: meson: meson8b: Initialize the HDMI PLL registersMartin Blumenstingl2-5/+48
Add the reg_sequence to initialize the HDMI PLL with the settings for a video mode that doesn't require PLL internal clock doubling. These settings are taken from the 3.10 vendor kernel's driver for the 2970MHz PLL setting used for the 1080P video mode. This puts the PLL into a defined state and the Linux kernel can take over. While not all bits for this PLL are implemented using these "defaults" and then applying M, N and FRAC seems to work fine.

2021-09-23clk: meson: meson8b: Add the HDMI PLL M/N parametersMartin Blumenstingl1-0/+22
The 3.10 vendor kernel uses only specific HDMI PLL M/N parameter combinations. The PLL won't lock for values smaller than 50 if the internal doubling (which is yet unknown how to use it) is disabled. However, when this doubling is enabled then the values smaller than 50 will lock just fine. The only restriction for values greater than 50 is that the resulting frequency must not exceed the 3.0GHz limit. These values are taken from the endlessm 3.10 kernel which includes additional M/N combinations for some VESA and 75Hz display modes.

2021-09-23clk: meson: meson8b: Add the vid_pll_lvds_en gate clockMartin Blumenstingl2-2/+24
HHI_VID_DIVIDER_CNTL[11] must be enabled for the video clock tree to work. This bit is described as "LVDS_CLK_EN". It is not 100% clear where this bit has to be placed in the hierarchy. But since the "LVDS_OUT" of the HDMI PLL uses it's own set of registers it's more likely that this "LVDS_CLK_EN" bit actually enables the input of the "hdmi_pll_lvds_out" clock to the "vid_pll_in_sel" tree. Add a gate definition for this bit (which will not be exported) so that the kernel can manage all required bits to enable and disable the video clocks.

2021-09-23clk: meson: meson8b: Use CLK_SET_RATE_NO_REPARENT for vclk{,2}_in_selMartin Blumenstingl1-2/+2
Use CLK_SET_RATE_NO_REPARENT for the vclk{,2}_in_sel clocks. The only parent which is actually used is vid_pll_final_div. This should be set using assigned-clock-parents in the .dts rather than removing some "unwanted" clock parents from the clock driver.

We have DT IDs for PCLK_COREDBG_L and PCLK_COREDBG_B, but we don't actually expose them.

2021-09-20clk: rockchip: rk3399: make CPU clocks criticalBrian Norris1-4/+7
The CPU clocks don't currently have any owner (e.g., cpufreq-dt doesn't enable() them -- and even if it did, it's not early enough compared to other consumers -- nor does arch/arm64/kernel/smp.c), and instead are simply assumed to be "on" all the time. They are also parents of a few other clocks which haven't been previously exposed for other devices to consume. If we want to expose those clocks, then the common clock framework may eventually choose to disable their parents (including the CPU PLLs) -- which is no fun for anyone. Thus, mark the CPU clocks as critical, to prevent them from being disabled implicitly.

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.

2021-09-14clk: qcom: gpucc-msm8998: Remove unnecessary fallbacks to global clocksMarijn Suijten1-3/+2
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.

2021-09-14clk: qcom: gcc-msm8998: Remove transient global "xo" clockMarijn Suijten1-27/+30
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.

2021-09-14clk: qcom: gcc-msm8998: Use parent_data/hws for internal clock relationsMarijn Suijten1-241/+281
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.
