[PATCH v3 0/6] imx93-11x11-evk: convert to OF_UPSTREAM

[Peng Fan (OSS)]

To support OF_UPSTREAM, a few driver changes are included.
For TMU, still use U-Boot node, I will prepare a kernel update,
then back to U-Boot support.
Add the pmic nodes to x-u-boot.dtsi, since upstream still not has it.
imx93.dtsi still kept because other boards still use it as of now.

Changes in v3:
- Update patch 5, to drop the imx8mp-evk changes which are wrongly
  included
- Link to v2: https://lore.kernel.org/r/20240328-imx93-of-v2-0-909f5d37da87@nxp.com

Changes in v2:
- Add a new patch to sync clock header to avoid breaking
- Drop the Makefile change which change including order
- Link to v1: https://lore.kernel.org/r/20240327-imx93-of-v1-0-afab6b31422a@nxp.com

[PATCH v3 2/6] serial: lpuart: use ipg clk for i.MX7ULP

[Peng Fan (OSS)]

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

To i.MX7ULP compatible lpuart, there is only ipg clk, no per clk.
So add a devtype check for i.MX7ULP.

Sumit and I asked you to add OF_UPSTREAM to all imx93 boards, not just this one.

Please don't ignore review comments.

I could help convert all imx93 boards, but I could only test nxp
