[PATCH v3 0/4] Add overlays to disable optional hardware in k3-am6xx-phycore-som boards

[Nathan Morrisson]

Add three overlays to disable the eth phy, rtc, and spi nor. These
overlays will be used to disable device tree nodes for components
that are optionally not populated.

v3:
  - Explain the logic behind adding the overlays in commit messages

v2:
  - Add build time tests in makefile

[PATCH v3 1/4] arm64: dts: ti: k3-am64-phycore-som: Add serial_flash label

[Nathan Morrisson]

Label the spi nor as serial_flash. This allows us to disable the
flash with an overlay common to all am6xx-phycore-som boards.

[PATCH v3 2/4] arm64: dts: ti: k3-am6xx-phycore-som: Add overlay to disable eth phy

[Nathan Morrisson]

Add an overlay to disable the eth phy for all am6xx-phycore-som
boards.
The EEPROM on am6xx-phycore-soms contains information about the
configuration of the SOM. The standard configuration of the SOM
has an ethernet phy, but if no ethernet phy is populated, the EEPROM
will indicate that change and we can use this overlay to cleanly
disable the ethernet phy.

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.
