stable inclusion from stable-v6.6.33 commit 1083681ea20874e3792b99f6ac7a8612acdc708b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit dcde4e97b122ac318aaa71e8bcd2857dc28a0d12 ]
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
