2022-09-14clk: microchip: mpfs: add reset controllerConor Dooley
Add a reset controller to PolarFire SoC's clock driver. This reset controller is registered as an aux device and read/write functions exported to the drivers namespace so that the reset controller can access the peripheral device reset register.

2022-09-14clk: microchip: mpfs: fix clk_cfg array bounds violationConor Dooley
There is an array bounds violation present during clock registration, triggered by current code by only specific toolchains. This seems to fail gracefully in v6.0-rc1, using a toolchain build from the riscv- gnu-toolchain repo and with clang-15, and life carries on. While converting the driver to use standard clock structs/ops, kernel panics were seen during boot when built with clang-15: [ 0.581754] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000b1 [ 0.591520] Oops [#1] [ 0.594045] Modules linked in: [ 0.597435] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.0.0-rc1-00011-g8e1459cf4eca #1 [ 0.606188] Hardware name: Microchip PolarFire-SoC Icicle Kit (DT) [ 0.613012] epc : __clk_register+0x4a6/0x85c [ 0.617759] ra : __clk_register+0x49e/0x85c [ 0.622489] epc : ffffffff803faf7c ra : ffffffff803faf74 sp : ffffffc80400b720 [ 0.630466] gp : ffffffff810e93f8 tp : ffffffe77fe60000 t0 : ffffffe77ffb3800 [ 0.638443] t1 : 000000000000000a t2 : ffffffffffffffff s0 : ffffffc80400b7c0 [ 0.646420] s1 : 0000000000000001 a0 : 0000000000000001 a1 : 0000000000000000 [ 0.654396] a2 : 0000000000000001 a3 : 0000000000000000 a4 : 0000000000000000 [ 0.662373] a5 : ffffffff803a5810 a6 : 0000000200000022 a7 : 0000000000000006 [ 0.670350] s2 : ffffffff81099d48 s3 : ffffffff80d6e28e s4 : 0000000000000028 [ 0.678327] s5 : ffffffff810ed3c8 s6 : ffffffff810ed3d0 s7 : ffffffe77ffbc100 [ 0.686304] s8 : ffffffe77ffb1540 s9 : ffffffe77ffb1540 s10: 0000000000000008 [ 0.694281] s11: 0000000000000000 t3 : 00000000000000c6 t4 : 0000000000000007 [ 0.702258] t5 : ffffffff810c78c0 t6 : ffffffe77ff88cd0 [ 0.708125] status: 0000000200000120 badaddr: 00000000000000b1 cause: 000000000000000d [ 0.716869] [<ffffffff803fb892>] devm_clk_hw_register+0x62/0xaa [ 0.723420] [<ffffffff80403412>] mpfs_clk_probe+0x1e0/0x244 In v6.0-rc1 and later, this issue is visible without the follow on patches doing the conversion using toolchains provided by our Yocto meta layer too. It fails on "clk_periph_timer" - which uses a different parent, that it tries to find using the macro: \#define PARENT_CLK(PARENT) (&mpfs_cfg_clks[CLK_##PARENT].cfg.hw) If parent is RTCREF, so the macro becomes: &mpfs_cfg_clks[33].cfg.hw which is well beyond the end of the array. Amazingly, builds with GCC 11.1 see no problem here, booting correctly and hooking the parent up etc. Builds with clang-15 do not, with the above panic. Change the macro to use specific offsets depending on the parent rather than the dt-binding's clock IDs.

2022-09-13clk: qcom: gcc-msm8909: Increase delay for USB PHY resetStephan Gerhold
The USB PHY on MSM8909 works with the driver used on MSM8916 (phy-qcom-usb-hs.c). When turning the PHY on/off it is first reset using the standard reset controller API. On MSM8916 the reset is provided by the USB driver (ci_hdrc_msm_por_reset() in ci_hdrc_msm.c). While this seems to work on MSM8909 as well, the Qualcomm Linux sources suggest that the PHY should be reset using the GCC_USB2_HS_PHY_ONLY_BCR register instead. In general this is easy to set up in the device tree, thanks to the standard reset controller API. However, to conform to the specifications of the PHY the reset signal should be asserted for at least 10 us. This is handled correctly on MSM8916 in ci_hdrc_msm_por_reset(), but not within the GCC driver. Fix this by making use of the new "udelay" field of qcom_reset_map and set a delay of ~15 us between the assertion/deassertion of the USB PHY reset signal.

2022-09-13clk: qcom: reset: Allow specifying custom reset delayStephan Gerhold
The amount of time required between asserting and deasserting the reset signal can vary depending on the involved hardware component. Sometimes 1 us might not be enough and a larger delay is necessary to conform to the specifications. Usually this is worked around in the consuming drivers, by replacing reset_control_reset() with a sequence of reset_control_assert(), waiting for a custom delay, followed by reset_control_deassert(). However, in some cases the driver making use of the reset is generic and can be used with different reset controllers. In this case the reset time requirement is better handled directly by the reset controller driver. Make this possible by adding an "udelay" field to the qcom_reset_map that allows setting a different reset delay (in microseconds).

The Snapdragon 670 adds and removes some clocks, adds new frequencies, and adds a new GPLL (Global Phase-Locked Loop) in reference to SDM845, while also removing some GDSCs. Despite these differences, there are many similarities with SDM670. Add data for SDM670 in the driver for SDM845 to reuse the most of the clock data. Advantages and disadvantages of this approach: + maintenance applies to both sdm670 and sdm845 by default + less duplicate code (clocks) means smaller distro/pre-built kernels with all drivers enabled - clocks for both SoC's must be compiled if the user wants clocks for one specific SoC (both or none) - additional testing needed for sdm845 devices Link: https://android.googlesource.com/kernel/msm/+/443bd8d6e2cf54698234c752e6de97b4b8a528bd%5E%21/#F10 Signed-off-by: Richard Acayan <mailingradian@gmail.com> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Bjorn Andersson <andersson@kernel.org> Link: https://lore.kernel.org/r/20220914013922.198778-4-mailingradian@gmail.com

2022-09-13dt-bindings: clock: Add "qcom,adsp-pil-mode" propertyTaniya Das
When this property is set, the remoteproc is used to boot the LPASS and therefore lpass_q6ss_ahbm_clk and lpass_q6ss_ahbs_clk clocks would be used to bring LPASS out of reset and the rest of the lpass clocks would be controlled directly by the remoteproc. This is a cleanup done to handle overlap of regmap of lpasscc and lpass_aon blocks.

2022-09-02clk: imx8mp: tune the order of enet_qos_root_clkPeng Fan
The enet_qos_root_clk takes sim_enet_root_clk as parent. When registering enet_qos_root_clk, it will be put into clk orphan list, because sim_enet_root_clk is not ready. When sim_enet_root_clk is ready, clk_core_reparent_orphans_nolock will set enet_qos_root_clk parent to sim_enet_root_clk. Because CLK_OPS_PARENT_ENABLE is set, sim_enet_root_clk will be enabled and disabled during the enet_qos_root_clk reparent phase. All the above are correct. But with M7 booted early and using enet, M7 enet feature will be broken, because clk driver probe phase disable the needed clks, in case M7 firmware not configure sim_enet_root_clk. And tune the order would also save cpu cycles.

2022-08-31clk: mediatek: mt8195-infra_ao: Set pwrmcu clocks as criticalAngeloGioacchino Del Regno
The pwrmcu is responsible for power management and idle states in SSPM: on older SoCs this was managed in Linux drivers like sspm/mcupm/eemgpu but, at least on MT8195, this functionality was transferred to the ATF firmware. For this reason, turning off the pwrmcu related clocks from the kernel will lead to unability to resume the platform after suspend and other currently unknown PM related side-effects. Set the PWRMCU and PWRMCU_BUS_H clocks as critical to prevent the kernel from turning them off, fixing the aforementioned issue.

2022-08-30clk: zynqmp: pll: rectify rate rounding in zynqmp_pll_round_rateQuanyang Wang
The function zynqmp_pll_round_rate is used to find a most appropriate PLL frequency which the hardware can generate according to the desired frequency. For example, if the desired frequency is 297MHz, considering the limited range from PS_PLL_VCO_MIN (1.5GHz) to PS_PLL_VCO_MAX (3.0GHz) of PLL, zynqmp_pll_round_rate should return 1.872GHz (297MHz * 5). There are two problems with the current code of zynqmp_pll_round_rate: 1) When the rate is below PS_PLL_VCO_MIN, it can't find a correct rate when the parameter "rate" is an integer multiple of *prate, in other words, if "f" is zero, zynqmp_pll_round_rate won't return a valid frequency which is from PS_PLL_VCO_MIN to PS_PLL_VCO_MAX. For example, *prate is 33MHz and the rate is 660MHz, zynqmp_pll_round_rate will not boost up rate and just return 660MHz, and this will cause clk_calc_new_rates failure since zynqmp_pll_round_rate returns an invalid rate out of its boundaries. 2) Even if the rate is higher than PS_PLL_VCO_MIN, there is still a risk that zynqmp_pll_round_rate returns an invalid rate because the function DIV_ROUND_CLOSEST makes some loss in the fractional part. If the parent clock *prate is 33333333Hz and we want to set the PLL rate to 1.5GHz, this function will return 1499999985Hz by using the formula below: value = *prate * DIV_ROUND_CLOSEST(rate, *prate)). This value is also invalid since it's slightly smaller than PS_PLL_VCO_MIN. because DIV_ROUND_CLOSEST makes some loss in the fractional part.
