Allwinner driver changes for 7.2 Mostly changes to the SRAM driver to allow for one SRAM region to be "claimed" by multiple changes. When a region is "claimed" it is removed or disconnected from the CPU's view. This is needed on the H6 and H616, which have one alias region seemingly shared between the video codec engine and the display engine. One minor fix for the RSB driver is also included. * tag 'sunxi-drivers-for-7.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: bus: sunxi-rsb: Always check register address validity soc: sunxi: sram: Add H616 SRAM regions soc: sunxi: sram: Support claiming multiple regions per device soc: sunxi: sram: Allow SRAM to be claimed multiple times soc: sunxi: sram: Const-ify sunxi_sram_func data and references dt-bindings: sram: sunxi-sram: Add H616 SRAM regions dt-bindings: sram: Document Allwinner H616 VE SRAM Signed-off-by: Krzysztof Kozlowski

bus: ts-nbus: drop unneeded dependency on OF_GPIO

2026-06-08T08:38:10+00:00

OF_GPIO is selected automatically on all OF systems. Any symbols it controls also provide stubs and are private to GPIOLIB anyway so there's really no reason to select it explicitly.

bus: mhi: host: pci_generic: Fix the physical function check

2026-05-27T15:43:11+00:00

Commit b4d01c5b9a9d ("bus: mhi: host: pci_generic: Read SUBSYSTEM_VENDOR_ID for VF's to check status") added the check for physical function by checking for 'pdev->is_physfn. But 'pdev->is_physfn' is only set for the physical function of a SR-IOV capable device. But for the non-SR-IOV device this variable will be 0. So this check ended up breaking the health check functionality for all non-SR-IOV devices. Fix it by checking for '!pdev->is_virtfn' to make sure that the check is only skipped for virtual functions.

bus: sunxi-rsb: Always check register address validity

2026-05-24T22:37:11+00:00

The register address was already validated for read operations in regmap_sunxi_rsb_reg_read before being truncated to a u8. Write operations have the same set of possible addresses, and the address is being truncated from u32 to u8 here as well, so the same check is needed.

This reverts commit 1a50d9403fb90cbe4dea0ec9fd0351d2ecbd8924. While the commit fixed fw_devlink overlay handling for one case, it broke it for another case.
