riscv: dts: sophgo: fix DMA data-width configuration for CV18xx

2025-05-22T12:29:35+00:00

[ Upstream commit 3e6244429ba38f8dee3336b8b805948276b281ab ] The "snps,data-width" property[1] defines the AXI data width of the DMA controller as: width = 8 × (2^n) bits (0 = 8 bits, 1 = 16 bits, 2 = 32 bits, ..., 6 = 512 bits) where "n" is the value of "snps,data-width". For the CV18xx DMA controller, the correct AXI data width is 32 bits, corresponding to "snps,data-width = 2". Test results on Milkv Duo S can be found here [2].

riscv: dts: Replace deprecated snps,nr-gpios property for snps,dw-apb-gpio-port devices

2024-10-25T11:32:16+00:00

riscv: dts: starfive: disable unused csi/camss nodes

2024-10-17T16:14:17+00:00

Aurelien reported probe failures due to the csi node being enabled without having a camera attached to it. A camera was in the initial submissions, but was removed from the dts, as it had not actually been present on the board, but was from an addon board used by the developer of the relevant drivers. The non-camera pipeline nodes were not disabled when this happened and the probe failures are problematic for Debian. Disable them.
