Pull clk updates from Stephen Boyd: "Mostly the usual clk driver updates and new SoC additions plus non-critical data fixes for things that weren't used yet. One thing that's new here in the core is SSC spread spectrum support (SSC) in the clk provider API. The idea is that DT authors will configure SSC for certain clks and they'll be configured at clk provider registration time or when a consumer device is probed, similar to how we handle assigned clk rates or parents. On the clk driver side we have Qualcomm adding almost half the diff because they add support for 4 different SoCs and then a long tail of other SoCs like Mediatek, Renesas, Rockchip, SpaceMiT, etc. add more SoC support this time around. Luckily it's mostly clk data for these new SoCs because the actual clk_ops are already there. Beyond the new drivers we get all the little fixups for more compilation coverage or usage of more modern APIs. That all looks normal. Finally, I kinda buried the lede, I'm bringing on Brian and Jerome to help out with maintaining the clk subsystem. The current working model is already semi-distributed in that silicon vendors typically take care of their drivers and send me pull requests but I'm becoming a bottleneck for new drivers and core framework review because this has become a 100% volunteer effort on my part. Mike is stepping down after all these years (thanks Mike!) and that jump started the conversation around finding co-maintainers. Brian and Jerome have graciously offered to help me with the work load, meaning in the future they'll be sending pull requests and committing directly to the clk.git tree. They've both been around on the list for a while, I've met them both in person, and they've been making changes to the core clk framework along with helping review patches so I'm pretty confident this will work well.

Pull ARM SoC platform updates from Arnd Bergmann: "The 32-bit Arm platforms are a bit more interesting this time: I refreshed an earlier series to mark code as deprecated that does have the tendency of getting in the way of cleanups and new features but has close to zero users. Among these are: - 22 of the remaining 28 legacy board files that predate the current devicetree based descriptions, using old chips from Intel and Marvell. The remaining six board files are for TI OMAP1 and Samsung s3c64xx chips and all still have known users. - support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25 machines based on these. These all use devicetree but the CPU support causes disproportional work. Most of them are just reference boards, the notable exceptions being the Nokia N800/N810 tablet and the Buglabs BUG platform. - be8, be32, oabi and iwmmxt userspace binaries, which were mostly associated with the platforms now scheduled for removal and are increasingly problematic to support with modern toolchains. Nothing is actually removed at this point, to ensure that any remaining users continue to have the 7.3-LTS for a while longer. Patches for removal are currently being tested. Other updates include a continued work to convert GPIO number based interfaces to descriptors, a patch to restore little-endian mode on the one Arm platform (ixp4xx) that only worked in big-endian mode recently, and some minor cleanups and bugfixes" * tag 'soc-arm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (41 commits) MAINTAINERS: Drop redundant lists from various Samsung entries ARM: tegra: Replace __ASSEMBLY__ with __ASSEMBLER__ ARM: tegra: Fix OF node reference leaks in IRQ init ARM: lpc32xx: remove a few manually populated OF devices ARM: lpc32xx: only run SoC init on LPC32xx hardware firmware: imx: scu: manage mailbox channels and global handle ARM: sa1100: h3xxx: convert gpio-keys to use software nodes ARM: sa1100: collie: convert gpio-keys to use software nodes ARM: sa1100: assabet: convert gpio-keys to use software nodes gpio: sa1100: register software node for GPIO controller ARM: ixp4xx: Relax endianness ARM: replace linux/gpio.h inclusions soc: imx9: devm_kasprintf error handling ARM: mark mv78xx0 support as deprecated ARM: mark axxia platform as deprecated ARM: mark Cortex-M3/M4/M7 based boards as deprecated ARM: mark footbridge as deprecated ARM: mark RiscPC as deprecated ARM: mark mach-sa1100 as deprecated ARM: orion5x: mark all board files as deprecated ...

soc: qcom: rpmh: Add support to read back resource settings

2026-08-07T14:19:40+00:00

All rpmh_*() APIs so far have supported placing votes for various resource settings but the H/W also have option to read resource settings. Add new rpmh_read() API to allow clients to read back resource setting from H/W. This will be useful for clients like regulators, which currently don't have a way to know the settings applied during bootloader stage.

ARM: tegra: Replace ASSEMBLY with ASSEMBLER

2026-07-31T15:39:10+00:00

While the GCC and Clang compilers already define __ASSEMBLER__ automatically when compiling assembly code, __ASSEMBLY__ is a macro that only gets defined by the Makefiles in the kernel. This can be very confusing when switching between userspace and kernelspace coding, or when dealing with uapi headers that rather should use __ASSEMBLER__ instead. So let's standardize now on the __ASSEMBLER__ macro that is provided by the compilers. This is a completely mechanical patch (done with a simple "sed -i" statement).

clk: spacemit: k3: fix i2s clock topology

2026-07-29T02:42:06+00:00

The K3 i2s clocks were modelled as a single path behind one MPMU register: pll1_d96_25p6 / i2s_153p6_base `-- i2s_sysclk_src (mux+gate, MPMU_ISCCR) `-- i2s1_sysclk (DDN, MPMU_ISCCR) |-- i2s_bclk (div+gate, MPMU_ISCCR) `-- i2s2_sysclk (mux, parent 0) The hardware actually has two i2s clock control registers, ISCCR0 (0x0040) and ISCCR1 (0x0044): ISCCR1 drives the common sysclk shared by i2s0/2/3/4/5 and the common bclk, whose divider always implies a fixed 1/2 factor in front, while ISCCR0 drives a dedicated path for i2s1: pll1_d96_25p6 / i2s_153p6_base |-- i2s_sysclk_src (mux+gate, MPMU_ISCCR1) | `-- i2s_sysclk (DDN, MPMU_ISCCR1) | |-- i2s_bclk_factor (fixed factor, /2) | | `-- i2s_bclk (div+gate, MPMU_ISCCR1) | `-- i2s2_sysclk (mux, parent 0) `-- i2s1_sysclk_src (mux+gate, MPMU_ISCCR0) `-- i2s1_sysclk (DDN, MPMU_ISCCR0) Because of this mismatch, i2s_bclk reported twice the real rate, and the dedicated i2s1 clock path could not be described in DT at all. Model the tree as above: split the MPMU_ISCCR register macro into MPMU_ISCCR0 and MPMU_ISCCR1 to match the hardware register names, rename the common DDN to i2s_sysclk, insert the fixed 1/2 factor i2s_bclk_factor in front of i2s_bclk, and add the i2s1_sysclk_src mux and i2s1_sysclk DDN backed by MPMU_ISCCR0. CLK_MPMU_I2S1_SYSCLK now refers to the dedicated i2s1 clock; no in-tree user references this ID, so nothing is affected by the change of meaning.
