git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "Mainly driver updates this time around. There's a single patch to the core clk framework that simplifies a runtime PM call. Otherwise the majority of the diff falls to a few SoC drivers: Qualcomm, STM32 and MediaTek. Those SoCs gain some new hardware support and what comes along with that is quite a few lines of data and some clk_ops code. Beyond the new hardware support we have the usual pile of driver updates that add missing clks on already supported SoCs or fix up problems like bad clk tree descriptions. It's nice to see that more drivers are moving to clk_hw based APIs too. New Drivers: - Add STM32MP13 RCC driver (Reset Clock Controller) - MediaTek MT8186 SoC clk support - Airoha EN7523 SoC system clocks - Clock driver for exynosautov9 SoC - Renesas R-Car V4H and RZ/V2M SoCs - Renesas RZ/G2UL SoC - LPASS clk driver for Qualcomm sc7280 SoC - GCC clk driver for Qualcomm SC8280XP SoC Updates: - SDCC uses floor clk ops on Qualcomm MSM8976 - Add modem reset and fix RPM clks on Qualcomm MSM8976 - Add the two missing CLKOUT clocks for U8500/DB8500 SoC - Mark some clks critical on Ingenic X1000 - Convert ux500 to clk_hw - Move MediaTek driver to clk_hw provider APIs - Use i2c driver probe_new to avoid id scans - Convert a number of Rockchip dt bindings to YAML - Mark hclk_vo critical on Rockchip rk3568 - Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage - Various cleanups like memory allocation error checks and plugged leaks - Allwinner H6 RTC clock support - Allwinner H616 32 kHz clock support - Add the Universal Flash Storage clock on Renesas R-Car S4-8 - Add I2C, SSIF-2 (sound), USB, CANFD, OSTM (timer), WDT, SPI Multi I/O Bus, RSPI, TSU (thermal), and ADC clocks and resets on Renesas RZ/G2UL - Add display clock support on Renesas RZ/G2L - Add RPC (QSPI/HyperFlash) clocks on Renesas R-Car E3 and D3 - Add 27 MHz phy PLL ref clock on i.MX - Add mcore_booted module parameter to tell kernel M core has already booted for i.MX - Remove snvs clock on i.MX because it was for secure world only - Add dt bindings for i.MX8MN GPT - Add DISP2 pixel clock for i.MX8MP - Add clkout1/2 for i.MX8MP - Fix parent clock of ubs_root_clk for i.MX8MP - Implement better RCG parking on Qualcomm SoCs using the shared RCG clk ops - Kerneldoc fixes - Switch Tegra BPMP to determine_rate clk op - Add a pointer to dt schema for generic clock bindings" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (168 commits) Revert "clk: qcom: regmap-mux: add pipe clk implementation" Revert "clk: qcom: gcc-sc7280: use new clk_regmap_mux_safe_ops for PCIe pipe clocks" Revert "clk: qcom: gcc-sm8450: use new clk_regmap_mux_safe_ops for PCIe pipe clocks" clk: bcm: rpi: Use correct order for the parameters of devm_kcalloc() clk: stm32mp13: add safe mux management clk: stm32mp13: add multi mux function clk: stm32mp13: add all STM32MP13 kernel clocks clk: stm32mp13: add all STM32MP13 peripheral clocks clk: stm32mp13: manage secured clocks clk: stm32mp13: add composite clock clk: stm32mp13: add stm32 divider clock clk: stm32mp13: add stm32_gate management clk: stm32mp13: add stm32_mux clock management clk: stm32: Introduce STM32MP13 RCC drivers (Reset Clock Controller) dt-bindings: rcc: stm32: add new compatible for STM32MP13 SoC clk: ti: clkctrl: replace usage of found with dedicated list iterator variable clk: ti: composite: Prefer kcalloc over open coded arithmetic dt-bindings: clock: exynosautov9: correct count of NR_CLK clk: mediatek: mt8173: Switch to clk_hw provider APIs clk: mediatek: Switch to clk_hw provider APIs ...

This driver manages Reset and Clock of STM32MP13 soc. It uses a clk-stm32-core module to manage stm32 gate, mux and divider for STM32MP13 and for new future soc. All gates, muxes, dividers are identify by an index and information are stored in array (register address, shift, with, flags...) This is useful when we have two clocks with the same gate or when one mux manages two output clocks.

asm-generic * 'remove-h8300' of git://git.infradead.org/users/hch/misc: remove the h8300 architecture This is clearly the least actively maintained architecture we have at the moment, and probably the least useful. It is now the only one that does not support MMUs at all, and most of the boards only support 4MB of RAM, out of which the defconfig kernel needs more than half just for .text/.data. Guenter Roeck did the original patch to remove the architecture in 2013 after it had already been obsolete for a while, and Yoshinori Sato brought it back in a much more modern form in 2015. Looking at the git history since the reinstantiation, it's clear that almost all commits in the tree are build fixes or cross-architecture cleanups: $ git log --no-merges --format=%an v4.5.. arch/h8300/ | sort | uniq -c | sort -rn | head -n 12 25 Masahiro Yamada 18 Christoph Hellwig 14 Mike Rapoport 9 Arnd Bergmann 8 Mark Rutland 7 Peter Zijlstra 6 Kees Cook 6 Ingo Molnar 6 Al Viro 5 Randy Dunlap 4 Yury Norov Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The real work that's in here is the typical pile of clk driver updates and new SoC support.

After that there are quite a few updates to the Allwinner (sunxi) drivers to support modular drivers and Renesas is heavily updated to add more support for various clks.

2021-12-15clk: Introduce clk-tps68470 driverHans de Goede
The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in the kernel the Regulators and Clocks are controlled by an OpRegion driver designed to work with power control methods defined in ACPI, but some platforms lack those methods, meaning drivers need to be able to consume the resources of these chips through the usual frameworks. This commit adds a driver for the clocks provided by the tps68470, and is designed to bind to the platform_device registered by the intel_skl_int3472 module. This is based on this out of tree driver written by Intel: https://github.com/intel/linux-intel-lts/blob/4.14/base/drivers/clk/clk-tps68470.c with various cleanups added.

For example, a generic arm64 kernel sees the following improvement when building the CCU core and drivers as modules: before: text data bss dec hex filename 13882360 5251670 360800 19494830 12977ae vmlinux after: text data bss dec hex filename 13734787 5086442 360800 19182029 124b1cd vmlinux So the result is a 390KB total reduction in kernel image size. The one early clock provider (sun5i) requires the core to be built in. Now that loading the MMC driver will trigger loading the CCU core, the MMC timing mode functions do not need a compile-time fallback.

2021-04-12clk: ralink: add clock driver for mt7621 SoCSergio Paracuellos
The documentation for this SOC only talks about two registers regarding to the clocks: * SYSC_REG_CPLL_CLKCFG0 - provides some information about boostrapped refclock. PLL and dividers used for CPU and some sort of BUS. * SYSC_REG_CPLL_CLKCFG1 - a banch of gates to enable/disable clocks for all or some ip cores. Looking into driver code, and some openWRT patched there are another frequencies which are used in some drivers (uart, sd...). According to all of this information the clock plan for this SoC is set as follows: - Main top clock "xtal" from where all the rest of the world is derived. - CPU clock "cpu" derived from "xtal" frequencies and a bunch of register reads and predividers. - BUS clock "bus" derived from "cpu" and with (cpu / 4) MHz. - Fixed clocks from "xtal": * "50m": 50 MHz. * "125m": 125 MHz. * "150m": 150 MHz. * "250m": 250 MHz. * "270m": 270 MHz. We also have a buch of gate clocks with their parents: * "hsdma": "150m" * "fe": "250m" * "sp_divtx": "270m" * "timer": "50m" * "pcm": "270m" * "pio": "50m" * "gdma": "bus" * "nand": "125m" * "i2c": "50m" * "i2s": "270m" * "spi": "bus" * "uart1": "50m" * "uart2": "50m" * "uart3": "50m" * "eth": "50m" * "pcie0": "125m" * "pcie1": "125m" * "pcie2": "125m" * "crypto": "250m" * "shxc": "50m" With this information the clk driver will provide clock and gates functionality from a a set of hardcoded clocks allowing to define a nice device tree without fixed clocks.

From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.

The Intel's eASIC N5X (ARCH_N5X) architecture shares a lot with Agilex (ARCH_AGILEX) so it uses the same socfpga_agilex.dtsi, with minor changes. Also the clock drivers are the same. However the clock drivers won't be build without ARCH_AGILEX. One could assume that ARCH_N5X simply depends on ARCH_AGILEX but this was not modeled in Kconfig. In current stage the ARCH_N5X is simply unbootable. Add a separate Kconfig entry for clocks used by both ARCH_N5X and ARCH_AGILEX so the necessary objects will be built if either of them is selected.

2021-02-22clk: Add RISC-V Canaan Kendryte K210 clock driverDamien Le Moal
Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC. This new driver with the compatible string "canaan,k210-clk" implements support for the full clock structure of the K210 SoC. Since it is required for the correct operation of the SoC, this driver is selected by default for compilation when the SOC_CANAAN option is selected. With this change, the k210-sysctl driver is turned into a simple platform driver which enables its power bus clock and triggers populating its child nodes. The sysctl driver retains the SOC early initialization code, but the implementation now relies on the new function k210_clk_early_init() provided by the new clk-k210 driver. The clock structure implemented and many of the coding ideas for the driver come from the work by Sean Anderson on the K210 support for the U-Boot project.

Otherwise the main new thing for the common clk framework is that it is selectable in the Kconfig language now. Hopefully this will let clk drivers and clk consumers be testable on more than the architectures that support the clk framework. The goal is to introduce some Kunit tests for the framework. Outside of the core framework we have the usual set of various driver updates and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the largest addition this time around in terms of lines of code.

This is a combination of two trivial bugs: - A platform should not be 'tristate', it should be a 'bool' symbol like the other platforms, if only for consistency, and to avoid surprises like this one. - The clk Makefile does not traverse into the sprd subdirectory if the platform is disabled but the drivers are enabled for compile-testing. Fixing either of the two would be sufficient to address the link failure, but for correctness, both need to be changed.

2020-05-30clk: Add Baikal-T1 CCU PLLs driverSerge Semin
Baikal-T1 is supposed to be supplied with a high-frequency external oscillator. But in order to create signals suitable for each IP-block embedded into the SoC the oscillator output is primarily connected to a set of CCU PLLs. There are five of them to create clocks for the MIPS P5600 cores, an embedded DDR controller, SATA, Ethernet and PCIe domains. The last three domains though named by the biggest system interfaces in fact include nearly all of the rest SoC peripherals. Each of the PLLs is based on True Circuits TSMC CLN28HPM IP-core with an interface wrapper (so called safe PLL' clocks switcher) to simplify the PLL configuration procedure. This driver creates the of-based hardware clocks to use them then in the corresponding subsystems. In order to simplify the driver code we split the functionality up into the PLLs clocks operations and hardware clocks declaration/registration procedures. Even though the PLLs are based on the same IP-core, they may have some differences. In particular, some CCU PLLs support the output clock change without gating them (like CPU or PCIe PLLs), while the others don't, some CCU PLLs are critical and aren't supposed to be gated. In order to cover all of these cases the hardware clocks driver is designed with an info-descriptor pattern. So there are special static descriptors declared for each PLL, which is then used to create a hardware clock with proper operations. Additionally debugfs-files are provided for each PLL' field to make sure the implemented rate-PLLs-dividers calculation algorithm is correct.
