2021-12-14clk: qcom: clk-alpha-pll: Don't reconfigure running TrionBjorn Andersson1-0/+9
commit a1f0019c342bd83240b05be68c9888549dde7935 upstream. In the event that the bootloader has configured the Trion PLL as source for the display clocks, e.g. for the continuous splashscreen, then there will also be RCGs that are clocked by this instance. Reconfiguring, and in particular disabling the output of, the PLL will cause issues for these downstream RCGs and has been shown to prevent them from being re-parented. Follow downstream and skip configuration if it's determined that the PLL is already running.

2021-12-14clk: qcom: regmap-mux: fix parent clock lookupDmitry Baryshkov3-1/+15
commit 9a61f813fcc8d56d85fcf9ca6119cf2b5ac91dd5 upstream. The function mux_get_parent() uses qcom_find_src_index() to find the parent clock index, which is incorrect: qcom_find_src_index() uses src enum for the lookup, while mux_get_parent() should use cfg field (which corresponds to the register value). Add qcom_find_cfg_index() function doing this kind of lookup and use it for mux parent lookup.

2021-11-25clk: qcom: gcc-msm8996: Drop (again) gcc_aggre1_pnoc_ahb_clkDmitry Baryshkov1-15/+0
[ Upstream commit 05cf3ec00d460b50088d421fb878a0f83f57e262 ] The gcc_aggre1_pnoc_ahb_clk is crucial for the proper MSM8996/APQ8096 functioning. If it gets disabled, several subsytems will stop working (including eMMC/SDCC and USB). There are no in-kernel users of this clock, so it is much simpler to remove from the kernel. The clock was first removed in the commit 9e60de1cf270 ("clk: qcom: Remove gcc_aggre1_pnoc_ahb_clk from msm8996") by Stephen Boyd, but got added back in the commit b567752144e3 ("clk: qcom: Add some missing gcc clks for msm8996") by Rajendra Nayak. Let's remove it again in hope that nobody adds it back.

2021-08-26clk: qcom: gcc-sdm660: Replace usage of parent_namesBjorn Andersson1-176/+194
Using parent_data and parent_hws, instead of parent_names, does protect against some cases of incompletely defined clock trees. While it turns out that the bug being chased this time was totally unrelated, this patch converts the SDM660 GCC driver to avoid such issues. The "xo" fixed_factor clock is unused within the gcc driver, but referenced from the DSI PHY. So it's left in place until the DSI driver is updated.

It adds function qcom_a53pll_get_freq_tbl() to create pll_freq_tbl from OPP, so that those a53pll frequencies can be defined in DT with operating-points-v2 bindings rather than being coded in the driver.

2021-08-06clk: qcom: gdsc: Ensure regulator init state matches GDSC stateBjorn Andersson1-18/+36
As GDSCs are registered and found to be already enabled gdsc_init() ensures that 1) the kernel state matches the hardware state, and 2) votable GDSCs are properly enabled from this master as well. But as the (optional) supply regulator is enabled deep into gdsc_toggle_logic(), which is only executed for votable GDSCs, the kernel's state of the regulator might not match the hardware. The regulator might be automatically turned off if no other users are present or the next call to gdsc_disable() would cause an unbalanced regulator_disable(). Given that the votable case deals with an already enabled GDSC, most of gdsc_enable() and gdsc_toggle_logic() can be skipped. Reduce it to just clearing the SW_COLLAPSE_MASK and enabling hardware control to simply call regulator_enable() in both cases. The enablement of hardware control seems to be an independent property from the GDSC being enabled, so this is moved outside that conditional segment. Lastly, as the propagation of ALWAYS_ON to GENPD_FLAG_ALWAYS_ON needs to happen regardless of the initial state this is grouped together with the other sc->pd updates at the end of the function.

Commit a0384ecfe2aa ("clk: qcom: smd-rpm: De-duplicate identical entries") introduces the following regression on MSM8936/MSM8939, as RPM_SMD_PCNOC_A_CLK gets pointed to pcnoc_clk by mistake. Fix it by correcting the clock to pcnoc_a_clk.
