The i.MX 7ULP family of processors represents NXP’s latest achievement
in ultra-low-power processing for use cases demanding long battery life.
Targeted towards the growing market of portable devices, the i.MX 7ULP
family of processors features NXP's advanced implementation of the Arm®
Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics
Processing Units (GPUs). The i.MX 7ULP family provides up to 32-bit
LPDDR2/LPDDR3 memory interface and a number of other interfaces for
connecting peripherals, such as WLAN, Bluetooth, GPS, displays, and
camera sensors.

This patch series adds the basic support for imx7ulp. It includes machine
level support code and device tree.
Note: it depends on clk driver which is still under review.

v4->v5:
 * dts add input clocks for PCC module
 * update pad setting due to missing pull up enabled
   (formerly auto done by driver generic pinconfg)
 * gpio and pinctrl patches were merged by Linus W, so dropped in this series
  dt-bindings: gpio: vf610: add optional clocks property
  gpio: vf610: add optional clock support
  dt-bindings: pinctrl: imx7ulp: back to imx legacy binding for
    consistency
  pinctrl: fsl: imx7ulp: change to use imx legacy binding

v3->v4:
 * add comments about fixed soc version
 * add iounmap
v2->v3:
 * back to old pinctrl binding according to SoC maintainer's suggestions
 * use generic node name
 * error checking updated according to Russell's suggestion:
   ptr == ERR_PTR(-EPROBE_DEFER)

v1->v2:
 * switch to SPDX license
 * rebase to latest tree
 * pad name update
 * add gpio clk support
 * minor fix

Hi Shawn,

Can you help pick up imx7ulp support series?
The clk patch set is already in clk tree now.
https://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git/log/?h=clk-imx7ulp

Please let me know if you need me to resend.

Regards
Dong Aisheng

+1

I added a simple commit log and applied the patch.
