2c917b55 - riscv: dts: canaan: Disable I/O devices unless used

Wed, 08 May 2024 10:20:58 +0000

riscv: dts: canaan: Disable I/O devices unless usedIt is considered good practice to disable on-SoC devices providingexternal I/O in the SoC-specific .dtsi, and enable them explicitly inthe board-specific DTS files when actually wired-up and used.Hence: - Set the status of I/O devices in k210.dtsi to "disabled", - Override the status of used I/O devices in board-specific DTS files to "okay", - Drop unneeded status overrides in board DTS-specific files for the always-enabled pin controller.On e.g. MAiXBiT, this gets rid of an error message when probing theunused slave-only spi2 controller: dw_spi_mmio 50240000.spi: error -22: problem registering spi host dw_spi_mmio 50240000.spi: probe with driver dw_spi_mmio failed with error -22which is seen since commit 98d75b9ef282f6b9 ("spi: dw: Drop defaultnumber of CS setting").Signed-off-by: Geert Uytterhoeven Reviewed-by: Damien Le Moal Signed-off-by: Conor Dooley List of files: /linux-6.15/scripts/dtc/include-prefixes/riscv/canaan/sipeed_maixduino.dts

9235784c - riscv: dts: canaan: Clean up serial aliases

Wed, 08 May 2024 10:20:57 +0000

riscv: dts: canaan: Clean up serial aliasesThe SoC-specific k210.dtsi declares aliases for all four serial ports.However, none of the board-specific DTS files configure pin control forany but the first serial port, so the last three ports are not usable.Move the aliases node from the SoC-specific k210.dtsi to theboard-specific DTS files, as these are really board-specific, and retainthe sole port that is usable.Signed-off-by: Geert Uytterhoeven Reviewed-by: Damien Le Moal Signed-off-by: Conor Dooley List of files: /linux-6.15/scripts/dtc/include-prefixes/riscv/canaan/sipeed_maixduino.dts
