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).

SP810 System Controller
-----------------------
Required properties:
- compatible: standard compatible string for a Primecell peripheral,
see Documentation/devicetree/bindings/arm/primecell.txt
for more details
should be: "arm,sp810", "arm,primecell"
- reg: standard registers property, physical address and size
of the control registers
- clock-names: from the common clock bindings, for more details see
Documentation/devicetree/bindings/clock/clock-bindings.txt;
should be: "refclk", "timclk", "apb_pclk"
- clocks: from the common clock bindings, phandle and clock
specifier pairs for the entries of clock-names property
- #clock-cells: from the common clock bindings;
should be: <1>
- clock-output-names: from the common clock bindings;
should be: "timerclken0", "timerclken1", "timerclken2", "timerclken3"
- assigned-clocks: from the common clock binding;
should be: clock specifier for each output clock of this
provider node
- assigned-clock-parents: from the common clock binding;
should be: phandle of input clock listed in clocks
property with the highest frequency
Example:
v2m_sysctl: sysctl@020000 {
compatible = "arm,sp810", "arm,primecell";
reg = <0x020000 0x1000>;
clocks = <&v2m_refclk32khz>, <&v2m_refclk1mhz>, <&smbclk>;
clock-names = "refclk", "timclk", "apb_pclk";
#clock-cells = <1>;
clock-output-names = "timerclken0", "timerclken1", "timerclken2", "timerclken3";
assigned-clocks = <&v2m_sysctl 0>, <&v2m_sysctl 1>, <&v2m_sysctl 3>, <&v2m_sysctl 3>;
assigned-clock-parents = <&v2m_refclk1mhz>, <&v2m_refclk1mhz>, <&v2m_refclk1mhz>, <&v2m_refclk1mhz>;
};
