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 USB DMA Controller Device Tree bindings
|
|
|
|
Required Properties:
|
|
-compatible: "renesas,<soctype>-usb-dmac", "renesas,usb-dmac" as fallback.
|
|
Examples with soctypes are:
|
|
- "renesas,r8a7790-usb-dmac" (R-Car H2)
|
|
- "renesas,r8a7791-usb-dmac" (R-Car M2-W)
|
|
- "renesas,r8a7793-usb-dmac" (R-Car M2-N)
|
|
- "renesas,r8a7794-usb-dmac" (R-Car E2)
|
|
- "renesas,r8a7795-usb-dmac" (R-Car H3)
|
|
- "renesas,r8a7796-usb-dmac" (R-Car M3-W)
|
|
- reg: base address and length of the registers block for the DMAC
|
|
- interrupts: interrupt specifiers for the DMAC, one for each entry in
|
|
interrupt-names.
|
|
- interrupt-names: one entry per channel, named "ch%u", where %u is the
|
|
channel number ranging from zero to the number of channels minus one.
|
|
- clocks: a list of phandle + clock-specifier pairs.
|
|
- #dma-cells: must be <1>, the cell specifies the channel number of the DMAC
|
|
port connected to the DMA client.
|
|
- dma-channels: number of DMA channels
|
|
|
|
