2019-10-23clk: samsung: exynos542x: Move G3D subsystem clocks to its sub-CMUMarek Szyprowski
G3D clocks require special handling of their parent bus clock during power domain on/off sequences. Those clocks were not initially added to the sub-CMU handler, because that time there was no open-source driver for the G3D (MALI Panfrost) hardware module and it was not possible to test it. This patch fixes this issue. Parent clock for G3D hardware block is now properly preserved during G3D power domain on/off sequence. This restores proper MALI Panfrost performance broken by commit 8686764fc071 ("ARM: dts: exynos: Add G3D power domain to Exynos542x").

2019-08-08clk: samsung: exynos542x: Move MSCL subsystem clocks to its sub-CMUMarek Szyprowski
M2M scaler clocks require special handling of their parent bus clock during power domain on/off sequences. MSCL clocks were not initially added to the sub-CMU handler, because that time there was no driver for the M2M scaler device and it was not possible to test it. This patch fixes this issue. Parent clock for M2M scaler devices is now properly preserved during MSC power domain on/off sequence. This gives M2M scaler devices proper performance: fullHD XRGB32 image 1000 rotations test takes 3.17s instead of 45.08s.

2019-08-08clk: samsung: exynos5800: Move MAU subsystem clocks to MAU sub-CMUSylwester Nawrocki
This patch fixes broken sound on Exynos5422/5800 platforms after system/suspend resume cycle in cases where the audio root clock is derived from MAU_EPLL_CLK. In order to preserve state of the USER_MUX_MAU_EPLL_CLK clock mux during system suspend/resume cycle for Exynos5800 we group the MAU block input clocks in "MAU" sub-CMU and add the clock mux control bit to .suspend_regs. This ensures that user configuration of the mux is not lost after the PMU block changes the mux setting to OSC_DIV when switching off the MAU power domain. Adding the SRC_TOP9 register to exynos5800_clk_regs[] array is not sufficient as at the time of the syscore_ops suspend call MAU power domain is already turned off and we already save and subsequently restore an incorrect register's value.

2019-07-17Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features. Core: - Add a 'clk_parent' file in clk debugfs - Add a clk_bulk_get_optional() API (with devm too) New Drivers: - Support gated clk controller on MIPS based BCM63XX SoCs - Support SiLabs Si5341 and Si5340 chips - Support for CPU clks on Raspberry Pi devices - Audsys clock driver for MediaTek MT8516 SoCs Updates: - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme - Small frequency support for SiLabs Si544 chips - Slow clk support for AT91 SAM9X60 SoCs - Remove dead code in various clk drivers (-Wunused) - Support for Marvell 98DX1135 SoCs - Get duty cycle of generic pwm clks - Improvement in mmc phase calculation and cleanup of some rate defintions - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs - Add GPIO, SNVS and GIC clocks for i.MX8 drivers - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting - Add clks for new Exynos5422 Dynamic Memory Controller driver - Clock definition for Exynos4412 Mali - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3 - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs - TI clock probing done from DT by default instead of firmware - Fix Amlogic Meson mpll fractional part and spread sprectrum issues - Add Amlogic meson8 audio clocks - Add Amlogic g12a temperature sensors clocks - Add Amlogic g12a and g12b cpu clocks - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W - Add Clock Domain support on Renesas RZ/N1" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (190 commits) clk: consoldiate the __clk_get_hw() declarations clk: sprd: Add check for return value of sprd_clk_regmap_init() clk: lochnagar: Update DT binding doc to include the primary SPDIF MCLK clk: Add Si5341/Si5340 driver dt-bindings: clock: Add silabs,si5341 clk: clk-si544: Implement small frequency change support clk: add BCM63XX gated clock controller driver devicetree: document the BCM63XX gated clock bindings clk: at91: sckc: use dedicated functions to unregister clock clk: at91: sckc: improve error path for sama5d4 sck registration clk: at91: sckc: remove unnecessary line clk: at91: sckc: improve error path for sam9x5 sck register clk: at91: sckc: add support to free slow clock osclillator clk: at91: sckc: add support to free slow rc oscillator clk: at91: sckc: add support to free slow oscillator clk: rockchip: export HDMIPHY clock on rk3228 clk: rockchip: add watchdog pclk on rk3328 clk: rockchip: add clock id for hdmi_phy special clock on rk3228 clk: rockchip: add clock id for watchdog pclk on rk3328 clk: at91: sckc: add support for SAM9X60 ...

Now that we've gotten rid of clk_readl() we can remove io.h from the clk-provider header and push out the io.h include to any code that isn't already including the io.h header but using things like readl/writel, etc. Found with this grep: git grep -l clk-provider.h | grep '.c$' | xargs git grep -L 'linux/io.h' | \ xargs git grep -l \ -e '\<__iowrite32_copy\>' --or \ -e '\<__ioread32_copy\>' --or \ -e '\<__iowrite64_copy\>' --or \ -e '\<ioremap_page_range\>' --or \ -e '\<ioremap_huge_init\>' --or \ -e '\<arch_ioremap_pud_supported\>' --or \ -e '\<arch_ioremap_pmd_supported\>' --or \ -e '\<devm_ioport_map\>' --or \ -e '\<devm_ioport_unmap\>' --or \ -e '\<IOMEM_ERR_PTR\>' --or \ -e '\<devm_ioremap\>' --or \ -e '\<devm_ioremap_nocache\>' --or \ -e '\<devm_ioremap_wc\>' --or \ -e '\<devm_iounmap\>' --or \ -e '\<devm_ioremap_release\>' --or \ -e '\<devm_memremap\>' --or \ -e '\<devm_memunmap\>' --or \ -e '\<__devm_memremap_pages\>' --or \ -e '\<pci_remap_cfgspace\>' --or \ -e '\<arch_has_dev_port\>' --or \ -e '\<arch_phys_wc_add\>' --or \ -e '\<arch_phys_wc_del\>' --or \ -e '\<memremap\>' --or \ -e '\<memunmap\>' --or \ -e '\<arch_io_reserve_memtype_wc\>' --or \ -e '\<arch_io_free_memtype_wc\>' --or \ -e '\<__io_aw\>' --or \ -e '\<__io_pbw\>' --or \ -e '\<__io_paw\>' --or \ -e '\<__io_pbr\>' --or \ -e '\<__io_par\>' --or \ -e '\<__raw_readb\>' --or \ -e '\<__raw_readw\>' --or \ -e '\<__raw_readl\>' --or \ -e '\<__raw_readq\>' --or \ -e '\<__raw_writeb\>' --or \ -e '\<__raw_writew\>' --or \ -e '\<__raw_writel\>' --or \ -e '\<__raw_writeq\>' --or \ -e '\<readb\>' --or \ -e '\<readw\>' --or \ -e '\<readl\>' --or \ -e '\<readq\>' --or \ -e '\<writeb\>' --or \ -e '\<writew\>' --or \ -e '\<writel\>' --or \ -e '\<writeq\>' --or \ -e '\<readb_relaxed\>' --or \ -e '\<readw_relaxed\>' --or \ -e '\<readl_relaxed\>' --or \ -e '\<readq_relaxed\>' --or \ -e '\<writeb_relaxed\>' --or \ -e '\<writew_relaxed\>' --or \ -e '\<writel_relaxed\>' --or \ -e '\<writeq_relaxed\>' --or \ -e '\<readsb\>' --or \ -e '\<readsw\>' --or \ -e '\<readsl\>' --or \ -e '\<readsq\>' --or \ -e '\<writesb\>' --or \ -e '\<writesw\>' --or \ -e '\<writesl\>' --or \ -e '\<writesq\>' --or \ -e '\<inb\>' --or \ -e '\<inw\>' --or \ -e '\<inl\>' --or \ -e '\<outb\>' --or \ -e '\<outw\>' --or \ -e '\<outl\>' --or \ -e '\<inb_p\>' --or \ -e '\<inw_p\>' --or \ -e '\<inl_p\>' --or \ -e '\<outb_p\>' --or \ -e '\<outw_p\>' --or \ -e '\<outl_p\>' --or \ -e '\<insb\>' --or \ -e '\<insw\>' --or \ -e '\<insl\>' --or \ -e '\<outsb\>' --or \ -e '\<outsw\>' --or \ -e '\<outsl\>' --or \ -e '\<insb_p\>' --or \ -e '\<insw_p\>' --or \ -e '\<insl_p\>' --or \ -e '\<outsb_p\>' --or \ -e '\<outsw_p\>' --or \ -e '\<outsl_p\>' --or \ -e '\<ioread8\>' --or \ -e '\<ioread16\>' --or \ -e '\<ioread32\>' --or \ -e '\<ioread64\>' --or \ -e '\<iowrite8\>' --or \ -e '\<iowrite16\>' --or \ -e '\<iowrite32\>' --or \ -e '\<iowrite64\>' --or \ -e '\<ioread16be\>' --or \ -e '\<ioread32be\>' --or \ -e '\<ioread64be\>' --or \ -e '\<iowrite16be\>' --or \ -e '\<iowrite32be\>' --or \ -e '\<iowrite64be\>' --or \ -e '\<ioread8_rep\>' --or \ -e '\<ioread16_rep\>' --or \ -e '\<ioread32_rep\>' --or \ -e '\<ioread64_rep\>' --or \ -e '\<iowrite8_rep\>' --or \ -e '\<iowrite16_rep\>' --or \ -e '\<iowrite32_rep\>' --or \ -e '\<iowrite64_rep\>' --or \ -e '\<__io_virt\>' --or \ -e '\<pci_iounmap\>' --or \ -e '\<virt_to_phys\>' --or \ -e '\<phys_to_virt\>' --or \ -e '\<ioremap_uc\>' --or \ -e '\<ioremap\>' --or \ -e '\<__ioremap\>' --or \ -e '\<iounmap\>' --or \ -e '\<ioremap\>' --or \ -e '\<ioremap_nocache\>' --or \ -e '\<ioremap_uc\>' --or \ -e '\<ioremap_wc\>' --or \ -e '\<ioremap_wc\>' --or \ -e '\<ioremap_wt\>' --or \ -e '\<ioport_map\>' --or \ -e '\<ioport_unmap\>' --or \ -e '\<ioport_map\>' --or \ -e '\<ioport_unmap\>' --or \ -e '\<xlate_dev_kmem_ptr\>' --or \ -e '\<xlate_dev_mem_ptr\>' --or \ -e '\<unxlate_dev_mem_ptr\>' --or \ -e '\<virt_to_bus\>' --or \ -e '\<bus_to_virt\>' --or \ -e '\<memset_io\>' --or \ -e '\<memcpy_fromio\>' --or \ -e '\<memcpy_toio\>' I also reordered a couple includes when they weren't alphabetical and removed clk.h from kona, replacing it with clk-provider.h because that driver doesn't use clk consumer APIs.
