| * | | | mfd: tps6594: Add driver for TI TPS6594 PMICJulien Panis2023-05-181-0/+1020
| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for TPS6594 PMIC MFD core. It provides communication through the I2C and SPI interfaces, and supports protocols with embedded CRC data fields for safety applications.

* | | | regulator: Add X-Powers AXP15060/AXP313a PMICMark Brown2023-06-061-0/+32
|\ \ \ \ | |_|/ / |/| | / | | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge series from Andre Przywara <andre.przywara@arm.com>: This patch series adds support for the X-Powers AXP15060 and AXP313a PMIC, which are general purpose PMICs as seen on different boards with different SOCs, mostly from Allwinner. This is mostly a repost of the previous patches, combining both the AXP313a and AXP15060 series, rebased on top of v6.4-rc3, and omitting the patches that already got merged. The first two patches are the successors of the AXP313a v10 post, the third patch is based on Shengyu's AXP15060 v3 post. There were no code changes, just some tiny context differences due to the rebase, plus I added the newly gained tags. As the DT bindings and the AXP15060 MFD part are already in the tree, this is just completing support with the MFD part for the AXP313a, and the regulator support for both PMICs.
| * | mfd: axp20x: Add support for AXP313a PMICMartin Botka2023-05-251-0/+32
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AXP313a is a PMIC chip produced by X-Powers, it can be connected via an I2C bus. The name AXP1530 seems to appear as well, and this is what is used in the BSP driver. From all we know it's the same chip, just a different name. However we have only seen AXP313a chips in the wild, so go with this name. Compared to the other AXP PMICs it's a rather simple affair: just three DCDC converters, three LDOs, and no battery charging support. Describe the regmap and the MFD bits, along with the registers exposed via I2C. Aside from the various regulators, also describe the power key interrupts, and adjust the shutdown handler routine to use a different register than the other PMICs. Eventually advertise the device using the new compatible string.

| * pwm: stm32: Enforce settings for PWM captureOlivier Moysan2023-04-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PWM capture assumes that the input selector is set to default input and that the slave mode is disabled. Force reset state for TISEL and SMCR registers to match this requirement. Note that slave mode disabling is not a pre-requisite by itself for capture mode, as hardware supports it for PWM capture. However, the current implementation of the driver does not allow slave mode for PWM capture. Setting slave mode for PWM capture results in wrong capture values.

The driver would disable PEK function if IRQ is not configured in device tree, since some boards (For example, Starfive Visionfive 2) didn't connect IRQ line of PMIC to SOC. GPIO function isn't enabled in this commit, since its configuration operation is different from any existing AXP PMICs and needs logic modification on existing driver. GPIO support might come in later patches.

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 ...

This can often be triggered when resuming from suspend if the power button is released before the kernel handles the interrupt.

Access to flash staging area is different for N6000 from that of the SPI interfaced counterparts. Introduce intel_m10bmc_flash_bulk_ops to allow interface specific differentiations for the flash access path for sec update and make m10bmc_sec_read/write() in sec update driver to use the new operations. The .flash_mutex serializes read/read. Flash update (erase+write) must use ->lock/unlock_write() to prevent reads during update (reads would timeout on setting flash MUX as BMC will prevent it). Create a type specific RSU status reg handler for N6000 because the field has moved from doorbell to auth result register. If a failure is detected while altering the flash MUX, it seems safer to try to set it back and doesn't seem harmful. Likely there are enough troubles in that case anyway so setting it back fails too (which is harmless sans the small extra delay) or just confirms that the value wasn't changed.

PMCI is a software-visible interface, connected to card BMC which provided the basic functionality of read/write BMC register. The access to the register is done indirectly via a hardware controller/bridge that handles read/write/clear commands and acknowledgments for the commands. Previously, intel-m10-bmc provided sysfs under /sys/bus/spi/devices/... which is generalized in this change because not all MAX10 BMC appear under SPI anymore.

The size of this info is expected to grow as more dev types and features are added which would have made the switch block bloaty. Store type specific info into struct and place them into .driver_data instead because it makes things a bit cleaner. The m10bmc_type enum can be dropped as the differentiation is now fully handled by the platform info. The info member of struct intel_m10bmc that is added here is not used yet in this change but its addition logically still belongs to this change. The CSR map change that comes after this change needs to have the info member.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.
