[PATCH V3 0/2] Add CAN and OSPI support for AM69-SK platform

[sabiya.d]

From: Dasnavis Sabiya <sabiya.d@ti.com>

Hi All,

This series adds support for the below interfaces on AM69-SK platform:
-  CAN support on both MCU and MAIN domains
-  OSPI NOR flash support

v3: Changelog:
1) Updated OSPI partition table to increase the tiboot3 partition to 1MB.
2) Rebase the sources to accommodate the latest merge.

v2: Changelog:
1) Removed CAN interface aliasing.
2) Updated bootph property on the leaf nodes.

[PATCH V3 1/2] arm64: dts: ti: k3-am69-sk: Enable CAN interfaces for AM69 SK board

[sabiya.d]

From: Dasnavis Sabiya <sabiya.d@ti.com>

AM69 SK board has several CAN bus interfaces on both MCU and MAIN domains.
This enables the CAN interfaces on MCU and MAIN domain.

[PATCH V3 2/2] arm64: dts: ti: k3-am69-sk: Add support for OSPI flash

[sabiya.d]

From: Dasnavis Sabiya <sabiya.d@ti.com>

AM69 SK has S28HS512T OSPI flash connected to MCU OSPI0.

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

[1/2] arm64: dts: ti: k3-am69-sk: Enable CAN interfaces for AM69 SK board

      commit: fabd934c6df2fb0c351144e424727fead261f333

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.
