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.

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
