[PATCH v3 0/3] arm64: dts: ti: add verdin am62 mallow board

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add Toradex Verdin AM62 Mallow carrier board support. Mallow is a
low-cost carrier board in the Verdin family with a small form factor and
build for volume production making it ideal for industrial and embedded
applications.

[PATCH v3 1/3] arm64: dts: ti: verdin-am62: improve spi1 chip-select pinctrl

[Francesco Dolcini]

From: Joao Paulo Goncalves <joao.goncalves@toradex.com>

Verdin SPI_1 interface has a dedicated hardware controlled chip select
that is currently configured in the same pinctrl group as MISO/MOSI/CLK,
however it is possible that it can be used only as a standard GPIO be it
a chip select or not.

To maximize flexibility and avoid duplication in the carrier board dts
files move the SPI_1 CS in a dedicated pinctrl and also adds an
additional pinctrl to simplify using SPI_1 CS as a GPIO.

[PATCH v3 3/3] arm64: dts: ti: add verdin am62 mallow board

[Francesco Dolcini]

From: Joao Paulo Goncalves <joao.goncalves@toradex.com>

Add Toradex Verdin AM62 Mallow carrier board support. Mallow is a
low-cost carrier board in the Verdin family with a small form factor and
build for volume production making it ideal for industrial and embedded
applications.

      commit: 7698622fbcf4fef2ec7e2fcbae35eb5e503dfddf

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.
