2021-03-24clk: tegra: Add PLLE HW power sequencer controlJC Kuo
PLLE has a hardware power sequencer logic which is a state machine that can power on/off PLLE without any software intervention. The sequencer has two inputs, one from XUSB UPHY PLL and the other from SATA UPHY PLL. PLLE provides reference clock to XUSB and SATA UPHY PLLs. When both of the downstream PLLs are powered-off, PLLE hardware power sequencer will automatically power off PLLE for power saving. XUSB and SATA UPHY PLLs also have their own hardware power sequencer logic. XUSB UPHY PLL is shared between XUSB SuperSpeed ports and PCIE controllers. The XUSB UPHY PLL hardware power sequencer has inputs from XUSB and PCIE. When all of the XUSB SuperSpeed ports and PCIE controllers are in low power state, XUSB UPHY PLL hardware power sequencer automatically power off PLL and flags idle to PLLE hardware power sequencer. Similar applies to SATA UPHY PLL. PLLE hardware power sequencer has to be enabled after both downstream sequencers are enabled. This commit adds two helper functions: 1. tegra210_plle_hw_sequence_start() for XUSB PADCTL driver to enable PLLE hardware sequencer at proper time. 2. tegra210_plle_hw_sequence_is_enabled() for XUSB PADCTL driver to check whether PLLE hardware sequencer has been enabled or not.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This is all driver updates, the majority of which is a bunch of new Qualcomm clk drivers that dominate the diffstat because we add support for six SoCs from that particular vendor. The other big change is the removal of various clk drivers that are no longer used now that the kernel is dropping support for those SoCs. Beyond that there's the usual non-critical fixes for existing drivers and a good number of patches from Lee Jones that cleanup a bunch of W=1 enabled builds. Removed Drivers: - Remove efm32 clk driver - Remove tango4 clk driver - Remove zte zx clk driver - Remove sirf prima2/atlast clk drivers - Remove u300 clk driver New Drivers: - PLL support on MStar/SigmaStar ARMv7 SoCs - CPU clks for Qualcomm SDX55 - GCC and RPMh clks for Qualcomm SC8180x and SC7280 SoCs - GCC clks for Qualcomm SM8350 - GPU clks for Qualcomm SDM660/SDM630 Updates: - Video clk fixups on Qualcomm SM8250 - Improvements for multimedia clks on Qualcomm MSM8998 - Fix many warnings with W=1 enabled builds under drivers/clk/ - Support crystal load capacitance for Versaclock VC5 - Add a "skip recall" DT binding for Silicon Labs' si570 to avoid glitches at boot - Convert Xilinx VCU clk driver to a proper clk provider driver - Expose Xilinx ZynqMP clk driver to more platforms - Amlogic pll driver fixup - Amlogic meson8b clock controller dt support clean up - Remove mipi clk from the Amlogic axg clock controller - New Rockchip rk3368 clock ids related to camera input - Use pr_notice() instead of pr_warn() on i.MX6Q pre-boot ldb_di_clk reparenting - A series from Liu Ying that adds some SCU clocks support for i.MX8qxp DC0/MIPI-LVDS subsystems - A series from Lucas Stach that adds PLL monitor clocks for i.MX8MQ, and clkout1/2 support for i.MX8MM/MN - Add I2c and Ethernet (RAVB) clocks on Renesas R-Car V3U - Add timer (TMU) clocks on most Renesas R-Car Gen3 SoCs - Add video-related (FCPVD/VSPD/VSPX), watchdog (RWDT), serial (HSCIF), pincontrol/GPIO (PFC/GPIO), SPI (MSIOF), SDHI, and DMA (SYS-DMAC) clocks on Renesas R-Car V3U - Add support for the USB 2.0 clock selector on Renesas RZ/G2 SoCs - Allwinner H616 SoC clk support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (171 commits) clk: mstar: msc313-mpll: Fix format specifier clk: mstar: Allow MStar clk drivers to be compile tested clk: qoriq: use macros to generate pll_mask clk: qcom: Add Global Clock controller (GCC) driver for SC7280 dt-bindings: clock: Add SC7280 GCC clock binding clk: qcom: rpmh: Add support for RPMH clocks on SC7280 dt-bindings: clock: Add RPMHCC bindings for SC7280 clk: qcom: gcc-sm8350: add gdsc dt-bindings: clock: Add QCOM SDM630 and SDM660 graphics clock bindings clk: qcom: Add SDM660 GPU Clock Controller (GPUCC) driver clk: qcom: mmcc-msm8996: Migrate gfx3d clock to clk_rcg2_gfx3d clk: qcom: rcg2: Stop hardcoding gfx3d pingpong parent numbers dt-bindings: clock: Add support for the SDM630 and SDM660 mmcc clk: qcom: Add SDM660 Multimedia Clock Controller (MMCC) driver clk: qcom: gcc-sdm660: Mark GPU CFG AHB clock as critical clk: qcom: gcc-sdm660: Mark MMSS NoC CFG AHB clock as critical clk: qcom: gpucc-msm8998: Allow fabia gpupll0 rate setting clk: qcom: gpucc-msm8998: Add resets, cxc, fix flags on gpu_gx_gdsc clk: qcom: gdsc: Implement NO_RET_PERIPH flag clk: mstar: MStar/SigmaStar MPLL driver ...

On a kernel built for selected SoCs, this allowed to build only limited set of matching clock drivers. However compile testing was not possible in such case as Makefile object depends on SOC/ARCH option. Add separate Kconfig options for each of them to be able to compile test.

2019-11-11clk: tegra: Add Tegra20/30 EMC clock implementationDmitry Osipenko
A proper External Memory Controller clock rounding and parent selection functionality is required by the EMC drivers, it is not available using the generic clock implementation because only the Memory Controller driver is aware of what clock rates are actually available for a particular device. EMC drivers will have to register a Tegra-specific CLK-API callback which will perform rounding of a requested rate. EMC clock users won't be able to request EMC clock by getting -EPROBE_DEFER until EMC driver is probed and the callback is set up. The functionality is somewhat similar to the clk-emc.c which serves Tegra124+ SoCs. The later HW generations support more parent clock sources and the HW configuration / integration with the EMC drivers differs a tad from the older gens, hence it's not really worth to try to squash everything into a single source file.

Add common library code for the Analog Bits Wide-Range PLL (WRPLL) IP block, as implemented in TSMC CLN28HPC. There is no bus interface or register target associated with this PLL. This library is intended to be used by drivers for IP blocks that expose registers connected to the PLL configuration and status signals.

2018-07-17ARM: at91: pm: Add ULP1 mode supportWenyou Yang
In the ULP1 mode, in order to achieve the lowest power consumption with the system in retention mode and be able to resume on the wake up events, all the clocks are shut off, inclusive the embedded 12MHz RC oscillator, and the number of wake up sources is limited as well. When the wake up event is asserted, the embedded 12MHz RC oscillator restarts automatically. The ULP1 (Ultra Low-power mode 1) is introduced by SAMA5D2. The previous size of pm_suspend.o was 2148 bytes. With the addition of ULP1 mode the new size of pm_suspend.o raised at 2456 bytes.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The large diff this time around is from the addition of a new clk driver for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well. Core: - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops - debugfs ops macroized to shave some lines of boilerplate code - Always calculate the phase instead of caching it in clk_get_phase() - More __must_check on bulk clk APIs New Drivers: - TI's Davinci family of SoCs - Intel's Stratix10 SoC - stm32mp157 SoC - Allwinner H6 CCU - Silicon Labs SI544 clock generator chip - Renesas R-Car M3-N and V3H SoCs - i.MX6SLL SoCs Removed Drivers: - ST-Ericsson AB8540/9540 Updates: - Mediatek MT2701 and MT7622 audsys support and MT2712 updates - STM32F469 DSI and STM32F769 sdmmc2 support - GPIO clks can sleep now - Spreadtrum SC9860 RTC clks - Nvidia Tegra MBIST workarounds and various minor fixes - Rockchip phase handling fixes and a memory leak plugged - Renesas drivers switch to readl/writel from clk_readl/clk_writel - Renesas gained CPU (Z/Z2) and watchdog support - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support - Qualcomm PM8921 PMIC XO buffers - Amlogic migrates to regmap APIs - TI Keystone clk latching support - Allwinner H3 and H5 video clk fixes - Broadcom BCM2835 PLLs needed another bit to enable - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix - i.MX6UL/ULL epdc_podf support - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (233 commits) clk: davinci: add a reset lookup table for psc0 clk: imx: add clock driver for imx6sll dt-bindings: imx: update clock doc for imx6sll clk: imx: add new gate/gate2 wrapper funtion clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux clk: cs2000: set pm_ops in hibernate-compatible way clk: bcm2835: De-assert/assert PLL reset signal when appropriate clk: imx7d: Move clks_init_on before any clock operations clk: imx7d: Correct ahb clk parent select clk: imx7d: Correct dram pll type clk: imx7d: Add USB clock information clk: socfpga: stratix10: add clock driver for Stratix10 platform dt-bindings: documentation: add clock bindings information for Stratix10 clk: ti: fix flag space conflict with clkctrl clocks clk: uniphier: add additional ethernet clock lines for Pro4 clk: uniphier: add SATA clock control support clk: uniphier: add PCIe clock control support clk: Add driver for the si544 clock generator chip clk: davinci: Remove redundant dev_err calls clk: uniphier: add ethernet clock control support for PXs3 ...
