Add basic device-tree for the MT8195 Demo board. The Demo board is made by MediaTek and has a MT8195 SoC, associated with the MT6359 and MT6360 PMICs, and the MT7921 connectivity chip. The IOs available on that board are: * 1 USB Type-C connector with DP aux mode support * 1 USB Type-A connector * 1 full size HDMI RX and 1 full size HDMI TX connector * 1 uSD slot * 40 pins header * SPI interface header * 1 M.2 slot * 1 audio jack * 1 micro-USB port for serial debug * 2 connectors for DSI displays * 3 connectors for CSI cameras * 1 connector for a eDP panel * 1 MMC storage This commit adds basic support in order to be able to boot.

In mt8192 SoC, mmc driver dose not use the MSDC module to control clock. It will read/write register to enable/disable clock. Also there is no other device of mt8192 using MSDC controller. We add mmc nodes for mt8192 SoC and remove the clock-controller in dts for avoid a duplicate unit-address(11f60000) warning. Signed-off-by:

The driver data of MT8183 and MT8173 are different. The value of has_gamma for MT8173 is true while the value of MT8183 is false. Therefore, the compatible of disp_aal for MT8183 is not suitable for the compatible for MT8173. Signed-off-by:

Commit 39bd2b6a ("dt-bindings: Improve phandle-array schemas") updated the mediatek,larbs property in the mediatek,iommu.yaml dt-binding to make it clearer that the phandles passed to the property are independent, rather than subsequent arguments to the first phandle. Update the mediatek,larbs property in the arm64 Devicetrees to use the same formatting. This change doesn't impact any behavior: the compiled dtb is exactly the same. It does however fix the warnings generated by dtbs_check. Signed-off-by:

Pull x86 fixes from Thomas Gleixner: "A set of x86 fixes and updates: - Make the prctl() for enabling dynamic XSTATE components correct so it adds the newly requested feature to the permission bitmap instead of overwriting it. Add a selftest which validates that. - Unroll string MMIO for encrypted SEV guests as the hypervisor cannot emulate it. - Handle supervisor states correctly in the FPU/XSTATE code so it takes the feature set of the fpstate buffer into account. The feature sets can differ between host and guest buffers. Guest buffers do not contain supervisor states. So far this was not an issue, but with enabling PASID it needs to be handled in the buffer offset calculation and in the permission bitmaps. - Avoid a gazillion of repeated CPUID invocations in by caching the values early in the FPU/XSTATE code. - Enable CONFIG_WERROR in x86 defconfig. - Make the X86 defconfigs more useful by adapting them to Y2022 reality" * tag 'x86-urgent-2022-04-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fpu/xstate: Consolidate size calculations x86/fpu/xstate: Handle supervisor states in XSTATE permissions x86/fpu/xsave: Handle compacted offsets correctly with supervisor states x86/fpu: Cache xfeature flags from CPUID x86/fpu/xsave: Initialize offset/size cache early x86/fpu: Remove unused supervisor only offsets x86/fpu: Remove redundant XCOMP_BV initialization x86/sev: Unroll string mmio with CC_ATTR_GUEST_UNROLL_STRING_IO x86/config: Make the x86 defconfigs a bit more usable x86/defconfig: Enable WERROR selftests/x86/amx: Update the ARCH_REQ_XCOMP_PERM test x86/fpu/xstate: Fix the ARCH_REQ_XCOMP_PERM implementation -

This reverts commit 7dabfa2b. There are multiple reports that this breaks boot on various systems. The common theme is that orphan clks are having rates set on them when that isn't expected. Let's revert it out for now so that -rc1 boots. Reported-by:
