Merge patch series "ti: j7: Update to v0.12.0 of DDR config tool"

2026-06-09T16:26:36Z

Neha Malcom Francis says: Update all DDR configuration DTSIs to the latest auto-generated output of the Sysconfig Tool (DDR Configuration for TDA4x, DRA8x, AM67x, AM68x, AM69x (0.12.00.0000)) [0] The auto-generated files must not be modified, but effort will be taken to change the tool output to adhere to the latest checkpatch.pl rules. J722S and J721E will also be updated in a subsequent series. All the changes have been kernel boot tested and memtester has passed (same as v1, as no functional changes made).

Merge patch series "Switch Apple silicon boards to upstream device trees"

2026-05-12T18:11:17Z

Janne Grunau says: The Linux device trees for Apple silicon devices cover now most of the hardware as u-boot's internal device trees for M1 devices. Linux has in addition device trees M2 and M1 and M2 Pro/Max/Ultra devices which were never added in u-boot. The most common use case for u-boot on Apple silicon devices does not use DTBs from u-boot but passes runtime modified device trees from an earlier boot loader (m1n1). This change regresses support for the SPI on M1 and M1 Pro/Max notebooks as SPI keyboard support is not in upstream Linux. This regression is in my opinion acceptable due to the limited use of u-boot's DTBs for these targets. Link: https://lore.kernel.org/r/20260507-apple-dt-upstream-v2-0-35181f2b0509@jannau.net

arm: dts: Switch Apple silicon devices to dts/upstream

2026-05-12T18:11:08Z

The device tree on Apple silicon devices is passed from a previous bootloader stage. The bootloader fills in dynamic information so u-boot can not use its own device tree. As documented in doc/board/apple/m1.rst it is possible to build boot bundles (bootloader + device tree + gzipped u-boot binary). These are useful for testing. Instead of using u-boot's own device trees for M1 (t8103) devices use upstream device trees from dts/upstream/src/arm64/apple. The u-boot device trees have not seen updates since 2022. The upstream linux device trees have feature parity for the M1 devices. In addition linux has device trees for M1 Pro/Max/Ultra, M2 and M2 Pro/Max/Ultra devices. Keep t8103-j274 as default device tree to avoid further updates. Signed-off-by: Janne Grunau Acked-by: Mark Kettenis
