2021-06-08clk: ti: add am33xx/am43xx spread spectrum clock supportDario Binacchi2-0/+124
The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs. As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for DDR, PER, and CORE PLLs. Calculating the required values and setting the registers accordingly was taken from the set_mpu_spreadspectrum routine contained in the arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project. In locked condition, DPLL output clock = CLKINP *[M/N]. In case of SSC enabled, the reference manual explains that there is a restriction of range of M values. Since the omap2_dpll_round_rate routine attempts to select the minimum possible N, the value of M obtained is not guaranteed to be within the range required. With the new "ti,min-div" parameter it is possible to increase N and consequently M to satisfy the constraint imposed by SSC.

2020-12-21Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linuxLinus Torvalds2-3/+20
Pull clk updates from Stephen Boyd: "The core framework got some nice improvements this time around. We gained the ability to get struct clk pointers from a struct clk_hw so that clk providers can consume the clks they provide, if they need to do something like that. This has been a long missing part of the clk provider API that will help us move away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are added for the clk_set_rate() "range" functions, similar to the tracepoints we already have for clk_set_rate() and we added a column to debugfs to help developers understand the hardware enable state of clks in case firmware or bootloader state is different than what is expected. Overall the core changes are mostly improving the clk driver writing experience. At the driver level, we have the usual collection of driver updates and new drivers for new SoCs. This time around the Qualcomm folks introduced a good handful of clk drivers for various parts of three or four SoCs. The SiFive folks added a new clk driver for their FU740 SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that for various new features. One last thing to note in the driver area is that the i.MX driver has gained a new binding to support SCU clks after being on the list for many months. It uses a two cell binding which is sort of rare in clk DT bindings. Beyond that we have the usual set of driver fixes and tweaks that come from more testing and finding out that some configuration was wrong or that a driver could support being built as a module. Summary: Core: - Add some trace points for clk_set_rate() "range" functions - Add hardware enable information to clk_summary debugfs - Replace clk-provider.h with of_clk.h when possible - Add devm variant of clk_notifier_register() - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw New Drivers: - Bindings for Canaan K210 SoC clks - Support for SiFive FU740 PRCI - Camera clks on Qualcomm SC7180 SoCs - GCC and RPMh clks on Qualcomm SDX55 SoCs - RPMh clks on Qualcomm SM8350 SoCs - LPASS clks on Qualcomm SM8250 SoCs Updates: - DVFS support for AT91 clk driver - Update git repo branch for Renesas clock drivers - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E - Stop using __raw_*() I/O accessors in Renesas clk drivers - One more conversion of DT bindings to json-schema - Make i.MX clk-gate2 driver more flexible - New two cell binding for i.MX SCU clks - Drop of_match_ptr() in i.MX8 clk drivers - Add arch dependencies for Rockchip clk drivers - Fix i2s on Rockchip rk3066 - Add MIPI DSI clks on Amlogic axg and g12 SoCs - Support modular builds of Amlogic clk drivers - Fix an Amlogic Video PLL clock dependency - Samsung Kconfig dependencies updates for better compile test coverage - Refactoring of the Samsung PLL clocks driver - Small Tegra driver cleanups - Minor fixes to Ingenic and VC5 clk drivers - Cleanup patches to remove unused variables and plug memory leaks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) dt-binding: clock: Document canaan,k210-clk bindings dt-bindings: Add Canaan vendor prefix clk: vc5: Use "idt,voltage-microvolt" instead of "idt,voltage-microvolts" clk: ingenic: Fix divider calculation with div tables clk: sunxi-ng: Make sure divider tables have sentinel clk: s2mps11: Fix a resource leak in error handling paths in the probe function clk: mvebu: a3700: fix the XTAL MODE pin to MPP1_9 clk: si5351: Wait for bit clear after PLL reset clk: at91: sam9x60: remove atmel,osc-bypass support clk: at91: sama7g5: register cpu clock clk: at91: clk-master: re-factor master clock clk: at91: sama7g5: do not allow cpu pll to go higher than 1GHz clk: at91: sama7g5: decrease lower limit for MCK0 rate clk: at91: sama7g5: remove mck0 from parent list of other clocks clk: at91: clk-sam9x60-pll: allow runtime changes for pll clk: at91: sama7g5: add 5th divisor for mck0 layout and characteristics clk: at91: clk-master: add 5th divisor for mck master clk: at91: sama7g5: allow SYS and CPU PLLs to be exported and referenced in DT dt-bindings: clock: at91: add sama7g5 pll defines clk: at91: sama7g5: fix compilation error ...
2020-12-17clk: ti: omap5: Fix reboot DPLL lock failure when using ABE TIMERsDavid Shah1-1/+11
Having the ABE DPLL ref and bypass muxes set to different inputs was causing the DPLL not to lock when TIMER8 was used, as it is in the Pyra for the backlight. This patch fixes this by setting abe_dpll_bypass_clk_mux to sys_32k_ck in omap5xxx_dt_clk_init. A similar patch may also be needed for OMAP44xx which has similar code in omap4xxx_dt_clk_init, but I have not added this as I have no hardware to test on.

2020-11-16clk: ti: am437x: Keep am4 l3 main clock always on for genpdTony Lindgren1-0/+8
In order for suspend and resume to work with genpd on am4, we must keep l3 main clock always on. Otherwise prm_omap driver will shut down the l3 main clock on suspend when simple-pm-bus and GENPD_FLAG_PM_CLK are used. Note that we already keep the l3 main clock always on with the legacy platform code. Later on we may want to start managing the l3 main clock with a dedicated interconnect driver instead of using simple-pm-bus and GENPD_FLAG_PM_CLK.

Pull clk updates from Stephen Boyd: "This time around we have four lines of diff in the core framework, removing a function that isn't used anymore. 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. After that the x86 (Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or upcoming SoCs. After that the dirstat shows the usual suspects working on their SoC support by fixing minor bugs, correcting data and converting some of their DT bindings to YAML. Core: - Allow the COMMON_CLK config to be selectable New Drivers: - Clk driver for Baikal-T1 SoCs - Mediatek MT6765 clock support - Support for Intel Agilex clks - Add support for X1830 and X1000 Ingenic SoC clk controllers - Add support for the new Renesas RZ/G1H (R8A7742) SoC - Add support for Qualcomm's MSM8939 Generic Clock Controller Updates: - Support IDT VersaClock 5P49V5925 - Bunch of updates for HSDK clock generation unit (CGU) driver - Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs - Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver - Enable supply regulators for GPU gdscs on Qualcomm SoCs - Add support for Si5342, Si5344 and Si5345 chips - Support custom flags in Xilinx zynq firmware - Various small fixes to the Xilinx clk driver - A single minor rounding fix for the legacy Allwinner clock support - A few patches from Abel Vesa as preparation of adding audiomix clock support on i.MX - A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and clk-pllv3 drivers - Drop dependency on ARM64 for i.MX8M clock driver, to support aarch32 mode on aarch64 hardware - A series from Peng Fan to improve i.MX8M clock drivers, using composite clock for core and bus clk slice - Set a better parent clock for flexcan on i.MX6UL to support CiA102 defined bit rates - A couple changes for EMC frequency scaling on Tegra210 - Support for CPU frequency scaling on Tegra20/Tegra30 - New clk gate for CSI test pattern generator on Tegra210 - Regression fixes for Samsung exynos542x and exynos5433 SoCs - Use of fallthrough; attribute for Samsung s3c24xx - Updates and fixup HDMI and video clocks on Meson8b - Fixup reset polarity on Meson8b - Fix GPU glitch free mux switch on Meson gx and g12 - A minor fix for the currently unused suspend/resume handling on Renesas RZ/A1 and RZ/A2 - Two more conversions of Renesas DT bindings to json-schema - Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (155 commits) clk: mediatek: Remove ifr{0,1}_cfg_regs structures clk: baikal-t1: remove redundant assignment to variable 'divider' clk: baikal-t1: fix spelling mistake "Uncompatible" -> "Incompatible" dt-bindings: clock: Add a missing include to MMP Audio Clock binding dt: Add bindings for IDT VersaClock 5P49V5925 clk: vc5: Add support for IDT VersaClock 5P49V6965 clk: Add Baikal-T1 CCU Dividers driver clk: Add Baikal-T1 CCU PLLs driver dt-bindings: clk: Add Baikal-T1 CCU Dividers binding dt-bindings: clk: Add Baikal-T1 CCU PLLs binding clk: mediatek: assign the initial value to clk_init_data of mtk_mux clk: mediatek: Add MT6765 clock support clk: mediatek: add mt6765 clock IDs dt-bindings: clock: mediatek: document clk bindings vcodecsys for Mediatek MT6765 SoC dt-bindings: clock: mediatek: document clk bindings mipi0a for Mediatek MT6765 SoC dt-bindings: clock: mediatek: document clk bindings for Mediatek MT6765 SoC CLK: HSDK: CGU: add support for 148.5MHz clock CLK: HSDK: CGU: support PLL bypassing CLK: HSDK: CGU: check if PLL is bypassed first clk: clk-si5341: Add support for the Si5345 series ...

Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well.

This leads into missed parent/child relationships (i.e. orphaned clocks) with mixed node name handling, for example with omap4/omap5 where the l4_per clocks are using new naming, but rest are using old.
