[PATCH V5 0/8] dt-bindinds/dts: support i.MX8ULP

[PATCH V5 0/8] dt-bindinds/dts: support i.MX8ULP

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>


V5:
 only fix patch 8/8 "arm64: dts: imx8ulp: Add the basic dts for imx8ulp evk board"
  - Correct bus-width to 8 for eMMC
  - Drop pinctrl enet which no user
 Drop patch 1/9 in V4, since in merged in linux-next
 Add A-b/R-b tag

V4:
 https://lists.infradead.org/pipermail/linux-arm-kernel/2021-November/696020.html

I just pick-up Jacky's work, rebase and send out V4 based on
Jacky's V3 patchset.

If you prefer to split the patchset and send single patches, I could
resend one by one.

Note: the V3 has a gpio bindings patch, it has been separated and
sent to gpio list in a single one per Linus requested.

This patchset is to add i.MX8ULP in dt-bindings, introduce
basic i.MX8ULP dtsi and basic evk board support.

The detailed version changes are in each patch.

There is checkpatch error in patch 8, but that is for device tree macro
and we could use use "(xx)".

In V4, the changes are in patch 8, 9 when rebasing to linux-next/master
,fix build errors after the clk driver in tree and drop a few nodes
that not have bindings.

Tested with CONFIG_CLK_IMX8ULP and CONFIG_PINCTRL_IMX8ULP enabled.

V3:

[PATCH V5 6/8] dt-bindings: arm: fsl: Add binding for imx8ulp evk

[Peng Fan (OSS)]

From: Jacky Bai <ping.bai@nxp.com>

Add the dt binding for i.MX8ULP EVK board.

i.MX 8ULP is part of the ULP family with emphasis on extreme
low-power techniques using the 28 nm fully depleted silicon on
insulator process. Like i.MX 7ULP, i.MX 8ULP continues to be
based on asymmetric architecture, however will add a third DSP
domain for advanced voice/audio capability and a Graphics domain
where it is possible to access graphics resources from the
application side or the realtime side.

From: Jacky Bai <ping.bai@nxp.com>

Add the basic dts file for i.MX8ULP EVK board.
Only the necessary devices for minimal system boot up are enabled:
enet, emmc, usb, console uart.

some of the devices' pin status may lost during low power mode,
so additional sleep pinctrl properties are included by default.

[3/8] dt-bindings: spi: fsl-lpspi: Add imx8ulp compatible string
      commit: 49cd1eb37b487036f51bd57b591f7b5760a10e02

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a 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.

Thanks,
Mark

For the several dt-bindings, patch 3 has been taken by SPI maintainer, 

All patches have got R-b or A-b tag.

would you pick others bindings or they should go through subsystem
maintainer's tree?

Thanks,
