Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull ARM SoC fixes from Olof Johansson: "I've been sitting on these longer than I meant, so the patch count is a bit higher than ideal for this part of the release. There's also some reverts of double-applied patches that brings the diffstat up a bit. With that said, the biggest changes are: - Revert of duplicate i2c device addition on two Aspeed (BMC) Devicetrees. - Move of two device nodes that got applied to the wrong part of the tree on ASpeed G6. - Regulator fix for Beaglebone X15 (adding 12/5V supplies) - Use interrupts for keys on Amlogic SM1 to avoid missed polls In addition to that, there is a collection of smaller DT fixes: - Power supply assignment fixes for i.MX6 - Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit - Build fixlets (selects) for davinci/omap2+ - More interrupt number fixes for Stratix10, Amlogic SM1, etc. - ... and more similar fixes across different platforms And some non-DT stuff: - optee fix to register multiple shared pages properly - Clock calculation fixes for MMP3 - Clock fixes for OMAP as well" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (42 commits) MAINTAINERS: Add myself as the co-maintainer for Actions Semi platforms ARM: dts: imx7: Fix Toradex Colibri iMX7S 256MB NAND flash support ARM: dts: imx6sll-evk: Remove incorrect power supply assignment ARM: dts: imx6sl-evk: Remove incorrect power supply assignment ARM: dts: imx6sx-sdb: Remove incorrect power supply assignment ARM: dts: imx6qdl-sabresd: Remove incorrect power supply assignment ARM: dts: imx6q-icore-mipi: Use 1.5 version of i.Core MX6DL ARM: omap2plus: select RESET_CONTROLLER ARM: davinci: select CONFIG_RESET_CONTROLLER ARM: dts: aspeed: rainier: Fix fan fault and presence ARM: dts: aspeed: rainier: Remove duplicate i2c busses ARM: dts: aspeed: tacoma: Remove duplicate flash nodes ARM: dts: aspeed: tacoma: Remove duplicate i2c busses ARM: dts: aspeed: tacoma: Fix fsi master node ARM: dts: aspeed-g6: Fix FSI master location ARM: dts: mmp3: Fix the TWSI ranges clk: mmp2: Fix the order of timer mux parents ARM: mmp: do not divide the clock rate arm64: dts: rockchip: Fix IR on Beelink A1 optee: Fix multi page dynamic shm pool alloc ...
