[PATCH] arm64: dts: ti: k3-am62d2-evm: Add support for OSPI flash
Posted by Paresh Bhagat 4 months, 1 week ago 
AM62D2 EVM has S28HS512T 64 MiB Octal SPI NOR flash connected to the
OSPI interface. Add support for the flash and describe the partition
information as per bootloader.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/1] arm64: dts: ti: k3-am62d2-evm: Add support for OSPI flash
      commit: 1a1066f553df1777ffa5ede050457e41972f34f4

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.

We already have issues with am62d that needs fixing:
cpu cpu0: _of_add_opp_table_v2: no supported OPPs
cpu cpu0: OPP table can't be empty

and

Please enable defconfig for this device
arch/arm64/boot/dts/ti/k3-am62d2-evm.dts:       typec_pd0: usb-power-controller@3f {

We can look at adding features for am62d after the above are done.
