More Qualcomm Arm64 DeviceTree updates for v6.20 Enable ADSP FastRPC and add missing GPU memory regions on Agatti. Also add the missing GPU regions on SM6115. Describe the application subsystem watchdog on Hamoa and enable this in the EL2 configurations. Add the camera control interface (CCI) I2C controller on MSM8953, and describe the camera regulators and the camera EEPROM on Fairphone FP3. Specify clock frequency for the i2c4 bus on OnePlus 6, to silence the warnings about missing frequency definition. Add FastRPC and associated heap memory, as well as Coresight, on SM8750 Switch a variety of platforms to use the generic RPMPD_ constants, instead of target-specific duplicated, to allow us to drop these from the header files. Drop the invalid opp-shared on the QUP OPP table for Talos. * tag 'qcom-arm64-for-6.20-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: arm64: dts: qcom: sm6115: Add CX_MEM/DBGC GPU regions arm64: dts: qcom: agatti: Add CX_MEM/DBGC GPU regions arm64: dts: qcom: sm8750: add ADSP fastrpc-compute-cb nodes arm64: dts: qcom: sm8750: add memory node for adsp fastrpc arm64: dts: qcom: switch to RPMPD_* indices arm64: dts: qcom: oneplus-enchilada: Specify i2c4 clock frequency arm64: dts: qcom: sm6350: Add clocks for aggre1 & aggre2 NoC arm64: dts: qcom: agatti: enable FastRPC on the ADSP arm64: qcom: dts: sm8750: add coresight nodes arm64: dts: qcom: talos: Drop opp-shared from QUP OPP table arm64: dts: qcom: x1-el2: Enable the APSS watchdog arm64: dts: qcom: hamoa: Add the APSS watchdog dt-bindings: watchdog: Document X1E80100 compatible arm64: dts: qcom: sdm632-fairphone-fp3: Enable CCI and add EEPROM arm64: dts: qcom: sdm632-fairphone-fp3: Add camera fixed regulators arm64: dts: qcom: msm8953: Add CCI nodes arm64: dts: qcom: msm8953: Re-sort tlmm pinctrl states Signed-off-by: Arnd Bergmann

dt-bindings: watchdog: samsung-wdt: Split if:then: and constrain more

2026-01-18T09:56:12+00:00

Binding defined two if:then: blocks covering different conditions but not fully constraining the properties per each variant: 1. "if:" to require samsung,syscon-phandle, 2. "if:" with "else:" to narrow number of clocks and require or disallow samsung,cluster-index. This still did not cover following cases: 1. Disallow samsung,syscon-phandle when not applicable, 2. Narrow samsung,cluster-index to [0, 1], for SoCs with only two clusters. Solving this in current format would lead to spaghetti code, so re-write entire "if:then:" approach into mutually exclusive cases so each SoC appears only in one "if:" block. This allows to forbid samsung,syscon-phandle for S3C6410, and narrow samsung,cluster-index to [0, 1].

dt-bindings: watchdog: samsung-wdt: Drop S3C2410

2026-01-18T09:56:12+00:00

Samsung S3C2410 SoC was removed from Linux kernel in the commit 61b7f8920b17 ("ARM: s3c: remove all s3c24xx support"), in January 2023. There are no in-kernel users of samsung,s3c2410-wdt compatible anymore and platform is so old, that there should be no out-of-tree users. If such existed, they would have enough of time to object dropping Samsung S3C2410 SoC removal from the kernel (which did not happen).
