Hi Nishanth,
This series adds GPMC and ELM controller device tree nodes to
AM64 SoC's dtsi file.
Changelog:
v4
- Rebased to v5.19
- use 'ti,am64-elm' compatible for ELM node
v3
- Rebased to v5.17-rc1
v2
- Fix register sizes for GPMC node.
- Disable GPMC and ELM nodes in board files. They will be enabled in
NAND card device tree overlay.

2.17.1
The ELM module is used for GPMC NAND accesses for detecting
and correcting errors during reads due to NAND bitflips errors.
4-, 8-, and 16-bit error-correction levels are supported using
the BCH (Bose-ChaudhurI-Hocquenghem) algorithm.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/2] arm64: dts: ti: k3-am64-main: Add GPMC memory controller node
commit: 5ec06904310da6441097c8f2d6e3fb196f42bca1
[2/2] arm64: dts: ti: k3-am64-main: Add ELM (Error Location Module) node
commit: c920a6caba68196f48f8ee57cc193e396f941011
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.
