clk: rs9: Fix suspend/resume

2023-03-21T17:47:06Z

Disabling the cache in commit 2ff4ba9e3702 ("clk: rs9: Fix I2C accessors") without removing cache synchronization in resume path results in a kernel panic as map->cache_ops is unset, due to REGCACHE_NONE. Enable flat cache again to support resume again. num_reg_defaults_raw is necessary to read the cache defaults from hardware. Some registers are strapped in hardware and cannot be provided in software.

clk: imx6ul: fix "failed to get parent" error

2023-03-20T21:25:38Z

On some configuration we may get following error: [ 0.000000] imx:clk-gpr-mux: failed to get parent (-EINVAL) This happens if selector is configured to not supported value. To avoid this warnings add dummy parents for not supported values.

clk: sprd: set max_register according to mapping range

2023-03-16T23:33:11Z

In sprd clock driver, regmap_config.max_register was set to a fixed value which is likely larger than the address range configured in device tree, when reading registers through debugfs it would cause access violation.

clk: k210: remove an implicit 64-bit division

2023-03-06T22:41:20Z

The K210 clock driver depends on SOC_CANAAN, which is only selectable when !MMU on RISC-V. !MMU is not possible on 32-bit yet, but patches have been sent for its enabling. The kernel test robot reported this implicit 64-bit division there. Replace the implicit division with an explicit one.

clk: HI655X: select REGMAP instead of depending on it

2023-03-06T19:31:14Z

REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".

kbuild, clk: remove MODULE_LICENSE in non-modules

2023-03-06T19:29:18Z

Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

Pull clk updates from Stephen Boyd: "We have one small patch to the clk core this time around. It fixes a corner case with the CLK_OPS_PARENT_ENABLE flag combined with clk_core_is_enabled() where it hangs the system. We'll simply assume the clk is disabled if the parent is disabled and the flag is set. Trying to turn on the parent to check the enable state of the clk runs into system hangs at boot. We let this bake in -next for a couple weeks to make sure there aren't any more issues because the last attempt to fix this ran into hangs and had to be reverted. Note: There were some more patches to the core framework around sync_state and disabling unused clks, but I asked for that to be reverted from the qcom PR because it isn't ready and we're still discussing the best solution on the list. Outside of the core clk framework, we have the usual collection of clk driver updates and support for new SoCs (which seems to never stop). The dirstat is dominated by Qualcomm because they added support for quite a few SoCs this time around and also migrated quite a few of their drivers to clk_parent_data. The other big diff is in the Mediatek clk drivers that saw a significant rework this cycle to similarly modernize the code, and we'll see that work continue in the next cycle as well. Nothing really jumps out as scary here, except that the significant churn in parent data descriptions can have typos that go unnoticed. More details below. Core: - Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled() New Drivers: - Add a new clk-gpr-mux clock type and use it on i.MX6Q to add ENET ref clocks - Support for Mediatek MT7891 SoC clks - Support for many Qualcomm clk controllers: - QDU1000/QRU1000 global clock controller - SA8775P global clock controller - SM8550 TCSR and display clock controller - SM6350 clock controller - MSM8996 CBF and APCS clock controllers Updates: - Various cleanups and improvements to Mediatek clk drivers to reduce code size and modernize the drivers - Support for Versa 5P49V60 clks - Disable R-Car H3 ES1.*, as it was only available to an internal development group and needed a lot of quirks and workarounds - Add PWM, Compare-Match Timer (TIM), USB, SDHI, and eMMC clocks and resets on Renesas RZ/V2M - Add display clocks on Renesas R-Car V4H - Add Camera Receiving Unit (CRU) clocks and resets on Renesas RZ/G2L - Free the imx_uart_clocks even if imx_register_uart_clocks returns early - Get the stdout clocks count from device tree on i.MX - Drop the clock count argument from imx_register_uart_clocks() - Keep the uart clocks on i.MX93 for when earlycon is used - Fix SPDX comment in i.MX6SLL clocks bindings header - Drop some unnecessary spaces from i.MX8ULP clocks bindings header - Add imx_obtain_fixed_of_clock() for allowing to add a clock that is not configured via devicetree - Fix the ENET1 gate configuration for i.MX6UL according to the reference manual - Add ENET refclock mux support for i.MX6UL - Add support for USB host/device configuration on Renesas RZ/N1 - Add PLL2 programming support, and CAN-FD clocks on Renesas R-Car V4H - Add D1 CAN bus gates and resets for Allwinner - Mark D1 CPUX clock as critical on Allwinner - Reuse D1 driver for Allwinner R528/T113 - Cleanup sunxi-ng Kconfig - Fix sunxi-ng kernel-doc issues - Model Allwinner H3/H5 DRAM clock as fixed clock - Use .determine_rate() instead of .round_rate() for the dualdiv, mpll, sclk-div and cpu-dyn-div amlogic clock drivers - DDR clocks were marked as critical in the proper clock driver for each AT91 SoC such that drivers/memory/atmel-sdramc.c to be deleted in the next releases as it only does clock enablement - Patch to avoid compiling dt-compat.o for all AT91 SoCs as only some of them may use it - Support synchronous power_off requests in the qcom GDSC driver for proper GPU power collapse - Drop test clocks from various Qualcomm clk drivers - Update parent references to use clk_parent_data/clk_hw in various Qualcomm clk drivers - Fixes for the Qualcomm MSM8996 CPU clock controller - Transition Qualcomm MSM8974 GCC off the externally defined sleep_clk - Add GDSCs in the global clock controller for Qualcomm QCS404 - The SDCC core clocks on Qualcomm SM6115 are moved to floor_ops - Programming of clk_dis_wait for GPU CX GDSC on Qualcomm SC7180 and SDM845 are moved to use the recently introduced properties in the GDSC struct - Qualcomm's RPMh clock driver gains SM8550 and SA8775P clocks, and the IPA clock is added on a variety of platforms - De-duplicate identical clks in Qualcomm SMD RPM clk driver - Add a few missing clocks across msm8998, msm8992, msm8916, qcs404 to Qualcomm SDM RPM clk driver - Various Qualcomm clk drivers use devm_pm_runtime_enable() to simplify" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (228 commits) clk: qcom: apcs-msm8986: Include bitfield.h for FIELD_PREP clk: qcom: Revert sync_state based clk_disable_unused clk: imx: pll14xx: fix recalc_rate for negative kdiv clk: rs9: Drop unused pin_xin field MAINTAINERS: clk: imx: Add Peng Fan as reviewer clk: sprd: Add dependency for SPRD_UMS512_CLK clk: ralink: fix 'mt7621_gate_is_enabled()' function clk: mediatek: clk-mtk: Remove unneeded semicolon dt-bindings: clock: remove stih416 bindings dt-bindings: clock: add loongson-2 clock dt-bindings: clock: add loongson-2 clock include file clk: imx: fix compile testing imxrt1050 clk: Honor CLK_OPS_PARENT_ENABLE in clk_core_is_enabled() clk: imx: set imx_clk_gpr_mux_ops storage-class-specifier to static clk: renesas: rcar-gen3: Disable R-Car H3 ES1.* dt-bindings: clock: Merge qcom,gpucc-sm8350 into qcom,gpucc.yaml clk: qcom: gpucc-sdm845: fix clk_dis_wait being programmed for CX GDSC clk: qcom: gpucc-sc7180: fix clk_dis_wait being programmed for CX GDSC dt-bindings: clock: qcom,sa8775p-gcc: add the power-domains property clk: qcom: cpu-8996: add missing cputype include ...
