git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round has a diffstat dominated by Qualcomm clk drivers. Honestly though that's just a bunch of data so the diffstat reflects that. Looking beyond that there's just a bunch of updates all around in various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall the driver changes look to be mostly enabling more clks and non-critical fixes that we could hold until the next merge window. I'm especially excited about the series from Arnd that graduates clkdev to be the only implementation of clk_get() and clk_put(). That's a good step in the right direction to migreate eveerything over to the common clk framework. Now we don't have to worry about clkdev specific details, they're just part of the clk API now. Core: - clkdev is now the only option, i.e. clk_get()/clk_put() is implemented in only one place in the kernel instead of in drivers/clk/clkdev.c and in architectures that want their own implementation New Drivers: - Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant Clock Jitter Cleaner With Dual Loop PLLs - Qualcomm MDM9607 GCC - Qualcomm SC8180X display clks - Qualcomm SM6125 GCC - Qualcomm SM8250 CAMCC (camera) - Renesas RZ/G2L SoC - Hisilicon hi3559A SoC Updates: - Stop using clock-output-names in ST clk drivers (yay!) - Support secure mode of STM32MP1 SoCs - Improve clock support for Actions S500 SoC - duty cycle setting support on qcom clks - Add TI am33xx spread spectrum clock support - Use determine_rate() for the Amlogic pll ops instead of round_rate() - Restrict Amlogic gp0/1 and audio plls range on g12a/sm1 - Improve Amlogic axg-audio controller error on deferral - Add NNA clocks on Amlogic g12a - Reduce memory footprint of Rockchip PLL rate tables - A fix for the newly added Rockchip rk3568 clk driver - Exported clock for the newly added Rockchip video decoder - Remove audio ipg clock from i.MX8MP - Remove deprecated legacy clock binding for i.MX SCU clock driver - Use common clk-imx8qxp for both i.MX8QXP and i.MX8QM - Add multiple clocks to clk-imx8qxp driver (enet, hdmi, lcdif, audio, parallel interface) - Add dedicated clock ops for i.MX paralel interface - Different fixes for clocks controlled by ATF on i.MX SoCs - Add A53/A72 frequency scaling support i.MX clk-scu driver - Add special case for DCSS clock on suspend for i.MX clk-scu driver - Add parent save/restore on suspend/resume to i.MX clk-scu driver - Skip runtime PM enablement for CPU clocks in i.MX clk-scu driver - Remove the sys1_pll/sys2_pll clock gates for i.MX8MQ and their bindings - Tegra clk driver no longer deasserts resets on clk_enable as it gets in the way of certain power-up sequences - Fix compile testing for Tegra clk driver - One patch to fix a divider on the Allwinner v3s Audio PLL - Add support for CPU core clock boost modes on Renesas R-Car Gen3 - Add ISPCS (Image Signal Processor) clocks on Renesas R-Car V3U - Switch SH/R-Mobile and R-Car "DIV6" clocks to .determine_rate() and improve support for multiple parents - Switch Renesas RZ/N1 divider clocks to .determine_rate() - Add ZA2 (Audio Clock Generator) clock on Renesas R-Car D3 - Convert ar7 to common clk framework - Convert ralink to common clk framework" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (161 commits) clk: zynqmp: Handle divider specific read only flag clk: zynqmp: Use firmware specific mux clock flags clk: zynqmp: Use firmware specific divider clock flags clk: zynqmp: Use firmware specific common clock flags clk: lmk04832: Use of match table clk: lmk04832: Depend on SPI clk: stm32mp1: new compatible for secure RCC support dt-bindings: clock: stm32mp1 new compatible for secure rcc dt-bindings: reset: add MCU HOLD BOOT ID for SCMI reset domains on stm32mp15 dt-bindings: reset: add IDs for SCMI reset domains on stm32mp15 dt-bindings: clock: add IDs for SCMI clocks on stm32mp15 reset: stm32mp1: remove stm32mp1 reset clk: hisilicon: Add clock driver for hi3559A SoC dt-bindings: Document the hi3559a clock bindings clk: si5341: Add sysfs properties to allow checking/resetting device faults clk: si5341: Add silabs,iovdd-33 property clk: si5341: Add silabs,xaxb-ext-clk property clk: si5341: Allow different output VDD_SEL values clk: si5341: Update initialization magic clk: si5341: Check for input clock presence and PLL lock on startup ...

2021-06-28clk: zynqmp: Use firmware specific common clock flagsRajan Vaja
Currently firmware passes CCF specific flags to ZynqMP clock driver. So firmware needs to be updated if CCF flags are changed. The firmware should have its own 'flag number space' that is distinct from the common clk framework's 'flag number space'. So define and use ZynqMP specific common clock flags instead of using CCF flags.

2021-06-28clk: stm32mp1: new compatible for secure RCC supportGabriel Fernandez
Platform STM32MP1 can be used in configuration where some clock resources cannot be accessed by Linux kernel when executing in non-secure state of the CPU(s). In such configuration, the RCC clock driver must not register clocks it cannot access. They are expected to be registered from another clock driver such as the SCMI clock driver. This change uses specific compatible string "st,stm32mp1-rcc-secure" to specify RCC clock driver configuration where RCC is secure.

2021-06-27clk: si5341: Avoid divide errors due to bogus register contentsRobert Hancock
If the Si5341 is being initially programmed and has no stored NVM configuration, some of the register contents may contain unexpected values, such as zeros, which could cause divide by zero errors during driver initialization.

2021-06-27clk: si5341: Wait for DEVICE_READY on startupRobert Hancock
The Si5341 datasheet warns that before accessing any other registers, including the PAGE register, we need to wait for the DEVICE_READY register to indicate the device is ready, or the process of the device loading its state from NVM can be corrupted. Wait for DEVICE_READY on startup before continuing initialization. This is done using a raw I2C register read prior to setting up regmap to avoid any potential unwanted automatic PAGE register accesses from regmap at this stage.

2021-06-27clk: Support bypassing dividersPaul Cercueil
When a clock is declared as both CGU_CLK_DIV and CGU_CLK_MUX, the CGU code expects the mux to be applied first, the divider second. On the JZ4760, and maybe on some other SoCs, some clocks also have a mux setting and a divider, but the divider is not applied to all parents selectable from the mux. This could be solved by creating two clocks, one with CGU_CLK_DIV and one with CGU_CLK_MUX, but that would increase the number of clocks. Instead, add a 8-bit mask to CGU_CLK_DIV clocks. If the bit corresponding to the parent clock's index is set, the divider is bypassed.

2021-06-27clk: actions: Fix AHPPREDIV-H-AHB clock chain on Owl S500 SoCCristian Ciocaltea
There are a few issues with the setup of the Actions Semi Owl S500 SoC's clock chain involving AHPPREDIV, H and AHB clocks: * AHBPREDIV clock is defined as a muxer only, although it also acts as a divider. * H clock is using a wrong divider register offset * AHB is defined as a multi-rate factor clock, but it is actually just a fixed pass clock. Let's provide the following fixes: * Change AHBPREDIV clock to an ungated OWL_COMP_DIV definition. * Use the correct register shift value in the OWL_DIVIDER definition for H clock * Drop the unneeded 'ahb_factor_table[]' and change AHB clock to an ungated OWL_COMP_FIXED_FACTOR definition.

2021-06-27clk: actions: Fix bisp_factor_table based clocks on Owl S500 SoCCristian Ciocaltea
The following clocks of the Actions Semi Owl S500 SoC have been defined to use a shared clock factor table 'bisp_factor_table[]': DE[1-2], VCE, VDE, BISP, SENSOR[0-1] There are several issues involved in this approach: * 'bisp_factor_table[]' describes the configuration of a regular 8-rates divider, so its usage is redundant. Additionally, judging by the BISP clock context, it is incomplete since it maps only 8 out of 12 possible entries. * The clocks mentioned above are not identical in terms of the available rates, therefore cannot rely on the same factor table. Specifically, BISP and SENSOR* are standard 12-rate dividers so their configuration should rely on a proper clock div table, while VCE and VDE require a factor table that is a actually a subset of the one needed for DE[1-2] clocks. Let's fix this by implementing the following: * Add new factor tables 'de_factor_table' and 'hde_factor_table' to properly handle DE[1-2], VCE and VDE clocks. * Add a common div table 'std12rate_div_table' for BISP and SENSOR[0-1] clocks converted to OWL_COMP_DIV. * Drop the now unused 'bisp_factor_table[]'. Additionally, drop the CLK_IGNORE_UNUSED flag for SENSOR[0-1] since there is no reason to always keep ON those clocks.
