threeeye bc1d038eac REVVL 6 Pro kernel bring-up: full working tree snapshot (2026-09-12)
Squashed backup commit (no shallow-clone history issues) of
xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream
commit 9eece662e) plus all fixes applied to get everpal_defconfig building
clean against a modern (GCC 15.2.0) toolchain -- see the previous commit
message on the lineage-23.2 branch (also in this repo history is not
available here since this is a squashed snapshot; full incremental history
lives in the local DL380 checkout and the upstream GitHub remote).

* Renesas usdhi6rol0 SD/SDIO host controller
Required properties:
- compatible: must be
"renesas,usdhi6rol0"
- interrupts: 3 interrupts, named "card detect", "data" and "SDIO" must be
specified
- clocks: a clock binding for the IMCLK input
Optional properties:
- vmmc-supply: a phandle of a regulator, supplying Vcc to the card
- vqmmc-supply: a phandle of a regulator, supplying VccQ to the card
- pinctrl-names: Can contain a "default" entry and a "state_uhs"
entry. The state_uhs entry is used together with the default
entry when the board requires distinct settings for UHS speeds.
- pinctrl-N: One property for each name listed in pinctrl-names, see
../pinctrl/pinctrl-bindings.txt.
Additionally any standard mmc bindings from mmc.txt can be used.
Example:
sd0: sd@ab000000 {
compatible = "renesas,usdhi6rol0";
reg = <0xab000000 0x200>;
interrupts = <0 23 0x4
0 24 0x4
0 25 0x4>;
interrupt-names = "card detect", "data", "SDIO";
bus-width = <4>;
max-frequency = <50000000>;
cap-power-off-card;
clocks = <&imclk>;
vmmc-supply = <&vcc_sd0>;
vqmmc-supply = <&vccq_sd0>;
};
