[PATCH v1 0/2] riscv: dts: starfive: visionfive 2: Remove non-existing hardware

[Hannah Peuckmann]

This series fixes the device tree for the VisionFive 2 which has nodes for
non-existing hardware which should have been left to overlays. It also results
in error on boot when both both the TDM and I2S drivers tries to claim GPIO 44.

[PATCH v1 1/2] riscv: dts: starfive: visionfive 2: Remove non-existing TDM hardware

[Hannah Peuckmann]

This partially reverts
commit e7c304c0346d ("riscv: dts: starfive: jh7110: add the node and pins configuration for tdm")

This added device tree nodes for TDM hardware that is not actually on the
VisionFive 2 board, but connected on the 40pin header. Many different extension
boards could be added on those pins, so this should be handled by overlays
instead.
This also conflicts with the I2S node which also attempts to grab GPIO 44:

  starfive-jh7110-sys-pinctrl 13040000.pinctrl: pin GPIO44 already requested by 10090000.tdm; cannot claim for 120c0000.i2s

[PATCH v1 2/2] riscv: dts: starfive: visionfive 2: Remove non-existing I2S hardware

[Hannah Peuckmann]

This partially reverts
commit 92cfc35838b2 ("riscv: dts: starfive: Add the nodes and pins of I2Srx/I2Stx0/I2Stx1")

This added device tree nodes for I2S hardware that is not actually on the
VisionFive 2 board, but connected on the 40pin header. Many different extension
boards could be added on those pins, so this should be handled by overlays
instead.
This also conflicts with the TDM node which also attempts to grab GPIO 44:

Thanks! This fixes the error mentioned in the commit messages for me.

Applied to riscv-dt-fixes, thanks. I should've probably realised this
when I merged them - thinking back I think I might even have had to do a
conflict resolution. Sorry about this.
