2025-01-07clk: qcom: gcc-x1e80100: Do not turn off usb_2 controller GDSCAbel Vesa1-1/+1
Allowing the usb_2 controller GDSC to be turned off during system suspend renders the controller unable to resume. So use PWRSTS_RET_ON instead in order to make sure this the GDSC doesn't go down.

2025-01-07clk: qcom: Add CMN PLL clock controller driver for IPQ SoCLuo Jie3-0/+445
The CMN PLL clock controller supplies clocks to the hardware blocks that together make up the Ethernet function on Qualcomm IPQ SoCs and to GCC. The driver is initially supported for IPQ9574 SoC. The CMN PLL clock controller expects a reference input clock from the on-board Wi-Fi block acting as clock source. The input reference clock needs to be configured to one of the supported clock rates. The controller supplies a number of fixed-rate output clocks. For the IPQ9574, there is one output clock of 353 MHZ to PPE (Packet Process Engine) hardware block, three 50 MHZ output clocks and an additional 25 MHZ output clock supplied to the connected Ethernet devices. The PLL also supplies a 24 MHZ clock as XO and a 32 KHZ sleep clock to GCC, and one 31.25 MHZ clock to PCS.

Add support for Pongo type of PLL clocks, used in Qualcomm SM8750 SoC. Notable difference comparing to other PLLs is the need for calibration for internally generated clock followed by wait_for_pll(). This is done in configure call and at this time clocks are not yet registered, thus wait_for_pll() cannot use clk_hw_get_name. Locking during this calibration requires much more time, thus increase the timeout in wait_for_pll().

2025-01-04clk: sunxi-ng: a64: stop force-selecting PLL-MIPI as TCON0 parentVasily Khoruzhick1-9/+4
Stop force-selecting PLL-MIPI as TCON0 parent, since it breaks video output on Pinebook that uses RGB to eDP bridge. Partially revert commit ca1170b69968 ("clk: sunxi-ng: a64: force select PLL_MIPI in TCON0 mux"), while still leaving CLK_SET_RATE_NO_REPARENT flag set, since we do not want the clock to be reparented. The issue is that apparently different TCON0 outputs require a different clock, or the mux might be selecting the output type. I did an experiment: I manually configured PLL_MIPI and PLL_VIDEO0_2X to the same clock rate and flipped the switch with devmem. Experiment clearly showed that whenever PLL_MIPI is selected as TCON0 clock parent, the video output stops working. Therefore, TCON0 clock parent corresponding to the output type must be assigned in the device tree.

While testing the MMC nodes proposed in [1], it was noted that mmc0/1 would fail to initialize, with "mmc: fatal err update clk timeout" in the kernel logs. A closer look at the clock definitions showed that the MMC MPs had the "CLK_SET_RATE_NO_REPARENT" flag set. No reason was given for adding this flag in the first place, and its original purpose is unknown, but it doesn't seem to make sense and results in severe limitations to MMC speeds.

2024-12-27clk: qcom: clk-alpha-pll: fix alpha mode configurationGabor Juhos1-0/+2
Commit c45ae598fc16 ("clk: qcom: support for alpha mode configuration") added support for configuring alpha mode, but it seems that the feature was never working in practice. The value of the alpha_{en,mode}_mask members of the configuration gets added to the value parameter passed to the regmap_update_bits() function, however the same values are not getting applied to the bitmask. As the result, the respective bits in the USER_CTL register are never modifed which leads to improper configuration of several PLLs. The following table shows the PLL configurations where the 'alpha_en_mask' member is set and which are passed as a parameter for the clk_alpha_pll_configure() function. In the table the 'expected rate' column shows the rate the PLL should run at with the given configuration, and the 'real rate' column shows the rate the PLL runs at actually. The real rates has been verified on hardwareOn IPQ* platforms, on other platforms, those are computed values only. file pll expected rate real rate dispcc-qcm2290.c disp_cc_pll0 768.0 MHz 768.0 MHz dispcc-sm6115.c disp_cc_pll0 768.0 MHz 768.0 MHz gcc-ipq5018.c ubi32_pll 1000.0 MHz != 984.0 MHz gcc-ipq6018.c nss_crypto_pll 1200.0 MHz 1200.0 MHz gcc-ipq6018.c ubi32_pll 1497.6 MHz != 1488.0 MHz gcc-ipq8074.c nss_crypto_pll 1200.0 MHz != 1190.4 MHz gcc-qcm2290.c gpll11 532.0 MHz != 518.4 MHz gcc-qcm2290.c gpll8 533.2 MHz != 518.4 MHz gcc-qcs404.c gpll3 921.6 MHz 921.6 MHz gcc-sm6115.c gpll11 600.0 MHz != 595.2 MHz gcc-sm6115.c gpll8 800.0 MHz != 787.2 MHz gpucc-sdm660.c gpu_cc_pll0 800.0 MHz != 787.2 MHz gpucc-sdm660.c gpu_cc_pll1 740.0 MHz != 729.6 MHz gpucc-sm6115.c gpu_cc_pll0 1200.0 MHz != 1190.4 MHz gpucc-sm6115.c gpu_cc_pll1 640.0 MHz != 633.6 MHz gpucc-sm6125.c gpu_pll0 1020.0 MHz != 1017.6 MHz gpucc-sm6125.c gpu_pll1 930.0 MHz != 921.6 MHz mmcc-sdm660.c mmpll8 930.0 MHz != 921.6 MHz mmcc-sdm660.c mmpll5 825.0 MHz != 806.4 MHz As it can be seen from the above, there are several PLLs which are configured incorrectly. Change the code to apply both 'alpha_en_mask' and 'alpha_mode_mask' values to the bitmask in order to configure the alpha mode correctly. Applying the 'alpha_en_mask' fixes the initial rate of the PLLs showed in the table above. Since the 'alpha_mode_mask' is not used by any driver currently, that part of the change causes no functional changes.

2024-12-27clk: qcom: dispcc-sm6115: remove alpha values from disp_cc_pll0_configGabor Juhos1-2/+0
Since both the 'alpha' and 'alpha_hi' members of the configuration is initialized (the latter is implicitly) with zero values, the output rate of the PLL will be the same whether alpha mode is enabled or not. Remove the initialization of the alpha* members to make it clear that the alpha mode is not required to get the desired output rate. Despite that enabling alpha mode is not needed for the initial configuration, the set_rate() op might require that it is enabled already. In this particular case however, the clk_alpha_pll_set_rate() function will get reset the ALPHA_EN bit when the PLL's rate changes, so dropping 'alpha_en_mask' is safe.
