[v4] Add support for K3 BIST

[PATCH v4 0/2] Add support for K3 BIST

Posted by Neha Malcom Francis 6 months, 2 weeks ago

BIST (Built-In Self Test) is an IP responsible for triggering hardware
circuitry tests on both logic as well as memory blocks. This driver is
currently being upstreamed in U-Boot [1] (on hold till the dt-binding
is approved here) and triggers these tests on cores. This patch series
adds the dt-binding as well as a node for BIST on J784S4 and J742S2.

Changes since v3:

Changes since v2:

- Krzysztof
	- use existing common definition (ti,sci-dev-id) for grabbing
	  the device ID instead of redefining properties

Changes since v1:

- Krzysztof
	- move from misc/ to soc/ti/
	- minor property changes
	- drop ti,bist-instance and instead opt for ti,bist-under-test
	- correct example dt

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

[1/2] dt-bindings: soc: ti: bist: Add BIST for K3 devices
      commit: 04ee170b69749851c74666079ac8f64dba52a2f1
[2/2] arm64: dts: ti: k3-j784s4-j742s2-main-common: Add PBIST_14 node
      commit: 387727d7e5d9c2499aafbd04e22c9d39e8eec4c5

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.

Nishanth,

Ok to take the dt-bindings via ti-k3-dts-next branch? Or would you
prefer to queue bindings and DT changes separately?

The ti-k3-dts-next should be fine here. I dont seem to have anything to
queue on the soc driver this time around..
