2024-02-07clk: qcom: gcc-sc8180x: Set delay for Venus CLK resetsKonrad Dybcio1-3/+3
Some Venus resets may require more time when toggling. Describe that. The value was obtained by referencing the msm-4.19 driver, which uses a single value for all platforms [1].

Some Venus resets may require more time when toggling. Describe that. The value was obtained on a best-guess basis: msm-5.4 being the base kernel for this SoC and 8775 being generally close to 8350 which is known to require a higher delay [1].

Trying to toggle the resets in a rapid fashion can lead to the changes not actually arriving at the clock controller block when we expect them to. This was observed at least on SM8250.

2024-02-07clk: samsung: gs101: add support for cmu_peric1André Draszik1-0/+346
CMU_PERIC1 is the clock management unit used for the peric1 block which is used for additional USI, I3C and PWM interfaces/busses. Add support for muxes, dividers and gates of cmu_peric1, except for CLK_GOUT_PERIC1_IP which isn't well described in the datasheet and which downstream also ignores (similar to cmu_peric0). Two clocks have been marked as CLK_IS_CRITICAL for the following reason: * disabling them makes it impossible to access any peric1 registers, (including those two registers). * disabling gout_peric1_lhm_axi_p_peric1_i_clk sometimes has the additional effect of making the whole system unresponsive. One clock marked as CLK_IGNORE_UNUSED needs to be kept on until we have updated the respective driver for the following reason: * gout_peric1_gpio_peric1_pclk is required by the pinctrl configuration. With this clock disabled, reconfiguring the pins (for USI/I2C, USI/UART) will hang during register access. Since pinctrl-samsung doesn't support a clock at the moment, we just keep the kernel from disabling it at boot, until we have an update for pinctrl-samsung, at which point we'll drop the flag.

The MSSPLL is really two stages - there's the PLL itself and 4 outputs, each with their own divider. The current driver models this as a single entity, outputting a single clock, used for both the CPU and AHB/AXI buses. The other 3 outputs are used for the eMMC, "user crypto" and CAN controller. Split the MSSPLL in two, as a precursor to adding support for the other 3 outputs, with the PLL itself as one "hw" clock and the output divider stage as another.

2024-02-01clk: samsung: exynos850: Propagate SPI IPCLK rate changeSam Protsenko1-16/+17
When SPI transfer is being prepared, the spi-s3c64xx driver will call clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK is a gate (leaf) clock, so it must propagate the rate change up the clock tree, so that corresponding DIV clocks can actually change their divider values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for all SPI instances in Exynos850 (spi_0, spi_1 and spi_2) to make it possible. This change involves next clocks: usi_spi_0: Clock Block Div range -------------------------------------------- gout_spi0_ipclk CMU_PERI - dout_peri_spi0 CMU_PERI /1..32 mout_peri_spi_user CMU_PERI - dout_peri_ip CMU_TOP /1..16 usi_cmgp0: Clock Block Div range -------------------------------------------- gout_cmgp_usi0_ipclk CMU_CMGP - dout_cmgp_usi0 CMU_CMGP /1..32 mout_cmgp_usi0 CMU_CMGP - gout_clkcmu_cmgp_bus CMU_APM - dout_apm_bus CMU_APM /1..8 usi_cmgp1: Clock Block Div range -------------------------------------------- gout_cmgp_usi1_ipclk CMU_CMGP - dout_cmgp_usi1 CMU_CMGP /1..32 mout_cmgp_usi1 CMU_CMGP - gout_clkcmu_cmgp_bus CMU_APM - dout_apm_bus CMU_APM /1..8 With input clock of 400 MHz, this scheme provides next IPCLK rate range, for each SPI block: SPI0: 781 kHz ... 400 MHz SPI1/2: 1.6 MHz ... 400 MHz Accounting for internal /4 divider in SPI blocks, and because the max SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates: SPI0: 200 kHz ... 49.9 MHz SPI1/2: 400 kHz ... 49.9 MHz Which should cover all possible applications of SPI bus. Of course, setting SPI frequency to values as low as 500 kHz will also affect the common bus dividers (dout_apm_bus or dout_peri_ip), which in turn effectively lowers the rates for all leaf bus clocks derived from those dividers, like HSI2C and I3C clocks. But at least it gives the board designer a choice, whether to keep all clocks (SPI/HSI2C/I3C) at high frequencies, or make all those clocks have lower frequencies. Not propagating the rate change to those common dividers would limit this choice to "only high frequencies are allowed for SPI/HSI2C/I3C" option, making the common dividers useless. This decision follows the "Worse is better" approach, relying on the users/engineers to know the system internals when working with such low-level features, instead of trying to account for all possible use-cases.

2024-01-30clk: qcom: gpucc-sc8280xp: Add external supply for GX gdscBjorn Andersson1-0/+1
On SA8295P and SA8540P the GFX rail is powered by a dedicated external regulator, instead of the rpmh-controlled "gfx.lvl". Define the "vdd-gfx" as the supply regulator for the GDSC, to cause the gdsc logic to look for, and control, this external power supply.

2024-01-30clk: qcom: gdsc: Enable supply reglator in GPU GX handlerBjorn Andersson1-2/+10
The GX GDSC is modelled to aid the GMU in powering down the GPU in the event that the GPU crashes, so that it can be restarted again. But in the event that the power-domain is supplied through a dedicated regulator (in contrast to being a subdomin of another power-domain), something needs to turn that regulator on, both to make sure things are powered and to match the operation in gdsc_disable().

Some boards might use Linux and another OS at the same time. In such case, currently, during booting, Linux will stop necessary module clocks which are not used on the Linux side, but are used by another OS. To avoid such situation, renesas-cpg-mssr tries to find status = "reserved" devices (A), and adds CLK_IGNORE_UNUSED flag to its <&cgp CPG_MOD xxx> clock (B). Table 2.4: Values for status property https://github.com/devicetree-org/devicetree-specification/releases/download/v0.4/devicetree-specification-v0.4.pdf "reserved" Indicates that the device is operational, but should not be used.
