https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/dt RISC-V Devicetrees for v6.20 (or v7.0) Anlogic: Minor change to the extension information, to add the "b" extension that's a catch-all for 3 of the extensions already in the dts. Starfive: Append the jh7110 compatible to jh7110s devicetrees, as that will enable OpenSBI etc to run without adding support for this minor variant. The "s" device differs from the non "s" device only in thermal limits and voltage/frequency characteristics. Microchip: Redo the mpfs clock setup yet again, to something approaching correct. The original binding conjured up for the platform was wildly inaccurate, and even with the original improvements, a bigger change to using syscons was required to support several peripherals that also inhabit the memory regions that the clocks lie in. The damage to the dts isn't that bad in the end, and of course the whole thing has been done in a backwards compatible manner, with the code changes being merged a cycle or two ago in the kernel and like a year ago in U-Boot (the only other user that I am aware of). Generic: Additions to extensions.yaml, mainly for things in the "rva23" profile that appear for the first time on the Spacemit K3 SoC.

Add descriptions for four extensions: Za64rs, Ziccamoa, Ziccif, and Zicclsm. These extensions are ratified in RISC-V Profiles Version 1.0 (commit b1d806605f87 "Updated to ratified state."). They are introduced as new extension names for existing features and regulate implementation details for RISC-V Profile compliance. According to RISC-V Profiles Version 1.0 and RVA23 Profiles Version 1.0, they are mandatory for the following profiles: - za64rs: Mandatory in RVA22U64, RVA23U64 - ziccamoa: Mandatory in RVA20U64, RVA22U64, RVA23U64 - ziccif: Mandatory in RVA20U64, RVA22U64, RVA23U64 - zicclsm: Mandatory in RVA20U64, RVA22U64, RVA23U64 Ziccrse specifies the main memory must support "RsrvEventual", which is one (totally there are four) of the support level for Load-Reserved/ Store-Conditional (LR/SC) atomic instructions. Thus it depends on Zalrsc. Ziccamoa specifies the main memory must support AMOArithmetic, among the four levels of PMA support defined for AMOs in the A extension. Thus it depends on Zaamo. Za64rs defines reservation sets are contiguous, naturally aligned, and a maximum of 64 bytes. Za64rs is consumed by two extensions: Zalrsc and Zawrs. Zawrs itself depends on Zalrsc too. Based on the relationship that "A" = Zaamo + Zalrsc, add the following dependencies checks: Za64rs -> Zalrsc or A Ziccrse -> Zalrsc or A Ziccamoa -> Zaamo or A Signed-off-by: Guodong Xu <guodong@riscstar.com> Acked-by: Conor Dooley <conor.dooley@microchip.com> Signed-off-by: Conor Dooley <conor.dooley@microchip.com>
2026-01-13dt-bindings: riscv: Add B ISA extension descriptionGuodong Xu
Add description of the single-letter B extension for Bit Manipulation. B is mandatory for RVA23U64. The B extension is ratified in the 20240411 version of the unprivileged ISA specification. According to the ratified spec, the B standard extension comprises instructions provided by the Zba, Zbb, and Zbs extensions. Add two-way dependency check to enforce that B implies Zba/Zbb/Zbs; and when Zba/Zbb/Zbs (all of them) are specified, then B must be added too. The reason why B/Zba/Zbb/Zbs must coexist at the same time is that unlike other single-letter extensions, B was ratified (Apr/2024) much later than its component extensions Zba/Zbb/Zbs (Jun/2021). When "b" is specified, zba/zbb/zbs must be present to ensure backward compatibility with existing software and kernels that only look for the explicit component strings. When all three components zba/zbb/zbs are specified, "b" should also be present. Making "b" mandatory when all three components are present. Existing devicetrees with zba/zbb/zbs but without "b" will generate warnings that can be fixed in follow-up patches.

https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/dt RISC-V Devicetrees for v6.19 MAINTAINERS: There's some re-jigging of things to reduce duplication, by moving me into the StarFive entry and my tree into the Microchip one. The other platforms that I look after (SiFive and Canaan) are marked as Odd Fixes to better represent their status. Nothing functionally changes. Microchip: Add adc and mmc nodes for the Beagle-V Fire. SiFive: Add pwm fans to the unmatched board. StarFive: Add the Orange PI RV board, another VisionFive 2 derived SBC. This required moving a mmc related nodes out of the common file, into <board>.dts. Yet more things moved out of the common file when the VisionFive 2 Lite boards were added, which use the JH7110S SoC instead of the JH7110. The difference here between SoCs is just temperature and frequency ranges, but the boards differ enough that the pool of common nodes decreases a little further. There's an eMMC and an SD variant here, that are different SKUs, bringing the total new StarFive boards to three.

Linux has been working on these for a while but stil requires patches. - Axis Artpec8 is an Armv8 chip based on Samsung Exynos design, unlike the earlier Armv7 Artpec6 from the same company that was part of a separate family of chips. - NXP i.MX91 is a cut-down version of i.MX93, using only a single Cortex-A55 core. - Qualcomm Lemans Auto is a variant of the Lemans SoC that was originally merged under the sa8775p name, the differences being mostly the firmware configuration of the platform. - Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44), RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial bedded SoCs based on Cortex-A55 cores In total, there are 65 new machines, including: - Industrial embedded system and single-board computers based on NXP, Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips. - Reference boards for the newly added Renesas, Qualcomm, NXP and Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC - Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1 chips. - Several Samsung phones using Qualcomm Snapdragon chips - Set-top boxes based on Allwinner H313 - Five BMC boards using 32-bit ASpeed SoCs - Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708 (ARMv7) SoCs Two machines get phased out because they were available only in small quantities but never made it into products: one STi407 based reference board, and a Snapdragon 845 based Chromebook.

Other than that, there's several cleanups done to the common JH7110 dtsi file, some relating to properties used by U-Boot or encountered during U-Boot development. Additionally, there's a binding and devicetree node for the memory controller on the JH7110. The memory controller only sees use in U-Boot, so the binding is here rather than in Krzysztof's branch. SiFive: Support for SiFive vendor-specific extensions in the binding file for extensions. These currently only see use in the SBI implementation. Microchip: Addition of support for the PolarFire SoC Discovery kit and non-engineering sample Icicle kit. The latter differs very slightly from the final ES devices due to bug fixes affecting functionality, and needs its own dts. To reduce duplication, the common portion of the two Icicle kits are moved into a dtsi. There's a few minor fixes here too, mostly low-hanging fruit detected during the addition of the Discovery kit that were then applied to the Icicle.

Add specific compatibles for the Icicle Kit with Production device (MPFS250T) and Icicle Kit with Engineering Sample (MPFS250T_ES). The icicle kit reference designs in the v2025.07 release include the Mi-V IHC IP v2, used to send/receive data between clusters when using Asymmetric Multiprocessing (AMP) mode. In reference design releases prior to v2025.07, the MI-V IHC subsystem was included as a proof of concept in the design prior to becoming an IP available in the Libero catalog. Among other improvements, the new Mi-V IHC IP v2 includes some changes to the register map. For this reason, make use of a new reference design compatible to denote that v2025.07 reference design releases are not backwards compatible.
