[PATCH v3 0/2] arm64: dts: ti: k3-j721e: MMC/SD higher speed modes support

[Sekhar Nori]

Hi,

This is repost of Faiz's patches adding higher speed modes
for J721E, originally posted here:'

https://lore.kernel.org/lkml/20201001190541.6364-1-faiz_abbas@ti.com/

Dependencies are resolved now, and patches rebased to latest linux-next.

v3:
- fix new node_name_chars_strict warning that got introduced

v2:
- rebased to latest linux-next
- fixed dtbs_check warning caused by improper states property in gpio
  regulator introduced in patch 2/2.

[PATCH v3 2/2] arm64: dts: ti: k3-j721e-common-proc-board: Add support for SD card UHS modes

[Sekhar Nori]

From: Faiz Abbas <faiz_abbas@ti.com>

Add support for UHS modes for the SD card connected at sdhci1. This
involves adding regulators for voltage switching and power cycling the
SD card and removing the no-1-8-v property.

Hi Sekhar Nori,

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

[1/2] arm64: dts: ti: k3-j721e-main: Add output tap delay values
      commit: 09ff4e90e041485f7562d9baec340a9824af4f45
[2/2] arm64: dts: ti: k3-j721e-common-proc-board: Add support for SD card UHS modes
      commit: cd48ce86a4d0c1ffec86aa46a26da993c9af5f53


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.
