[PATCH v4 00/12] arm64: prepare and add verdin imx8m mini support

[Marcel Ziswiler]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>


Fix strange hex notation and gpio-hog example, rebuild default
configuration, enable various relevant configuration options mainly to
be built as modules, add toradex,verdin-imx8mm et al. to dt-bindings and
finally, add initial support for Verdin iMX8M Mini.

Changes in v4:
- Re-base on top of Shawn's for-next branch.
- Fix gpio-line-names taking V1.1 re-design into account.
- Fix wrong SODIMM pin number.
- Drop 2nd SPI CAN instance being N/A in all SKUs.

Changes in v3:
- Add Krzysztof's reviewed-by tag.
- Add Krzysztof's reviewed-by tag.
- New separate patch only for re-ordering as suggested by Krzysztof.
- Not dropping CONFIG_SECCOMP=y, CONFIG_SLIMBUS=m, CONFIG_INTERCONNECT=y
  and CONFIG_CONFIGFS_FS=y as requested by Krzysztof.
- Add Krzysztof's reviewed-by tag.
- New patch enabling imx8m pcie phy driver in arm64 defconfig.
- Add Krzysztof's reviewed-by tag.
- Add Krzysztof's reviewed-by tag.
- Rebase on top of shawnguo's for-next.
- Drop [PATCH v2 02/11] ("dt-bindings: gpio: fix gpio-hog example") as
  it already got applied by Bart.
- Remove the 'pm-ignore-notify' property analogous to commit aafac22d6b23
  ("arm64: dts: imx8mm/n: Remove the 'pm-ignore-notify' property").
- Now with PCIe support finally having landed in -next enable it as well.
- Add Krzysztof's acked-by tag.

Changes in v2:
- Add Laurent's reviewed-by tag.
- New patch following full defconfig analysis as requested by Krzysztof.
- New patch following full defconfig analysis as requested by Krzysztof.
- Done full defconfig analysis as requested by Krzysztof.
- Add Song's acked-by tag.
- A similar change got accepted for imx_v6_v7_defconfig. Further
  discussion may be found in [1].

- Explain why enabling it may be a good idea as requested by Krzysztof.
- Explain why enabling these may make sense and squash them relevant
  changes as requested by Krzysztof.
- Add Rob's acked-by tag.
- Fix Colibri vs. Verdin copy/paste mistake. Thanks to Francesco Dolcini
  <francesco.dolcini@toradex.com> for pointing that out to me.

  by Krzysztof.
- Remove the previously #ifdefed-out spi-nor as requested by Krzysztof.
- Fix capitalisation in cover-letter.

 firewall, but the local system does not support BPF/cgroup firewalling.
[    2.630916] systemd[1]: (This warning is only shown for the first
 unit using IP firewalling.)
