Thank you! [1/1] arm64: dts: ti: k3-am62a7-sk: Add interrupt support for IO Expander commit: e57ba268254bda25a3ddca8b7971d6ad8277e2d8 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. [1] https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git

The Hot Plug Detect (HPD) signal for the HDMI display travels from the on-board HDMI connector, through the IO Expander 1, and finally to the main_gpio1 line #23, of the SoC. Add interrupt information for the IO Expander 1 (exp1). Also add pinmux info of main gpio 1, line #23. Signed-off-by: Aradhya Bhatia <a-bhatia1@ti.com> --- Notes: - HDMI display on AM62A7 is not in the mainline yet. All the patches, including this one, required to enable HDMI display and HPD on AM62A7 SK-EVM, can be found on my github fork in the branch "next_am62a-v3"[0].
