[PATCH v4] arm64: defconfig: Enable TI PRUSS

[PATCH v4] arm64: defconfig: Enable TI PRUSS

[MD Danish Anwar]

The Programmable Realtime Unit - Industrial Communication Subsystem
(PRU-ICSS) known as PRUSS, is a low-latency microcontroller subsystem
used for industrial networking and other hard real-time functions in
the TI K3 SoCs such as AM654x, AM64x.

AM654x-EVM, AM64xx-EVM, and iot2050 use the PRUSS driver.

*) Modified commit-message to add details on PRUSS driver and the SoCs
   supported. (address comments from v2 - Konard's and v3 - Nishanth's)

Thanks a lot, sounds like it's a cool piece of hardware!

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

[1/1] arm64: defconfig: Enable TI PRUSS
      commit: b7314d6938759d6da8b9992d0eade4606daf72a6

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.
