linux/drivers/reset, branch v6.8

Merge tag 'soc-drivers-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2024-01-11T19:31:46Z

Pull SoC driver updates from Arnd Bergmann: "A new drivers/cache/ subsystem is added to contain drivers for abstracting cache flush methods on riscv and potentially others, as this is needed for handling non-coherent DMA but several SoCs require nonstandard hardware methods for it. op-tee gains support for asynchronous notification with FF-A, as well as support for a system thread for executing in secure world. The tee, reset, bus, memory and scmi subsystems have a couple of minor updates. Platform specific soc driver changes include: - Samsung Exynos gains driver support for Google GS101 (Tensor G1) across multiple subsystems - Qualcomm Snapdragon gains support for SM8650 and X1E along with added features for some other SoCs - Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195, and driver support for MT8188 along with some code refactoring. - Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream - Apple M1 mailbox driver is rewritten into a SoC driver - minor updates on amlogic, mvebu, ti, zynq, imx, renesas and hisilicon" * tag 'soc-drivers-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (189 commits) memory: ti-emif-pm: Convert to platform remove callback returning void memory: ti-aemif: Convert to platform remove callback returning void memory: tegra210-emc: Convert to platform remove callback returning void memory: tegra186-emc: Convert to platform remove callback returning void memory: stm32-fmc2-ebi: Convert to platform remove callback returning void memory: exynos5422-dmc: Convert to platform remove callback returning void memory: renesas-rpc-if: Convert to platform remove callback returning void memory: omap-gpmc: Convert to platform remove callback returning void memory: mtk-smi: Convert to platform remove callback returning void memory: jz4780-nemc: Convert to platform remove callback returning void memory: fsl_ifc: Convert to platform remove callback returning void memory: fsl-corenet-cf: Convert to platform remove callback returning void memory: emif: Convert to platform remove callback returning void memory: brcmstb_memc: Convert to platform remove callback returning void memory: brcmstb_dpfe: Convert to platform remove callback returning void soc: qcom: llcc: Fix LLCC_TRP_ATTR2_CFGn offset firmware: qcom: qseecom: fix memory leaks in error paths dt-bindings: clock: google,gs101: rename CMU_TOP gate defines soc: qcom: llcc: Fix typo in kernel-doc dt-bindings: soc: qcom,aoss-qmp: document the X1E80100 Always-On Subsystem side channel ...

reset: Fix crash when freeing non-existent optional resets

2023-11-30T14:02:21Z

When obtaining one or more optional resets, non-existent resets are stored as NULL pointers, and all related error and cleanup paths need to take this into account. Currently only reset_control_put() and reset_control_bulk_put() get this right. All of __reset_control_bulk_get(), of_reset_control_array_get(), and reset_control_array_put() lack the proper checking, causing NULL pointer dereferences on failure or release. Fix this by moving the existing check from reset_control_bulk_put() to __reset_control_put_internal(), so it applies to all callers. The double check in reset_control_put() doesn't hurt.

reset: Use device_get_match_data()

2023-11-28T16:23:01Z

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers.
