Merge tag 'soc-late-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull more ARM SoC updates from Arnd Bergmann: "These are changes that for some reason ended up not making it into the first four branches but that should still make it into 6.9: - A rework of the omap clock support that touches both drivers and device tree files - The reset controller branch changes that had a dependency on late bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the drivers branch - The RISC-V/starfive, RISC-V/microchip and ARM/Broadcom devicetree changes that got delayed and needed some extra time in linux-next for wider testing" * tag 'soc-late-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (31 commits) soc: fsl: dpio: fix kcalloc() argument order bus: ts-nbus: Improve error reporting bus: ts-nbus: Convert to atomic pwm API riscv: dts: starfive: jh7110: Add camera subsystem nodes ARM: bcm: stop selecing CONFIG_TICK_ONESHOT ARM: dts: omap3: Update clksel clocks to use reg instead of ti,bit-shift ARM: dts: am3: Update clksel clocks to use reg instead of ti,bit-shift clk: ti: Improve clksel clock bit parsing for reg property clk: ti: Handle possible address in the node name dt-bindings: pwm: opencores: Add compatible for StarFive JH8100 dt-bindings: riscv: cpus: reg matches hart ID reset: Instantiate reset GPIO controller for shared reset-gpios reset: gpio: Add GPIO-based reset controller cpufreq: do not open-code of_phandle_args_equal() of: Add of_phandle_args_equal() helper reset: simple: add support for Sophgo SG2042 dt-bindings: reset: sophgo: support SG2042 riscv: dts: microchip: add specific compatible for mpfs pdma riscv: dts: microchip: add missing CAN bus clocks ARM: brcmstb: Add debug UART entry for 74165 ...
