Subject: [PATCH v6 0/9] Add i.MX91 platform support

The design of i.MX91 platform is very similar to i.MX93.
Extracts the common parts in order to reuse code.

The mainly difference between i.MX91 and i.MX93 is as follows:
- i.MX91 removed some clocks and modified the names of some clocks.
- i.MX91 only has one A core.
- i.MX91 has different pinmux.
- i.MX91 has updated to new temperature sensor same with i.MX95.

---
Changes for v6:
- add changelog in per patch.
- correct commit message spell for patch #1.
- merge rename imx93.dtsi to imx91_93_common.dtsi and move i.MX93
  specific part from imx91_93_common.dtsi to imx93.dtsi for patch #3.
- modify the commit message for patch #3.
- restore copyright time and add modification time for common dtsi for patch #3.
- remove unused map0 label in imx91_93_common.dtsi for patch #3.
- remove tmu related node for patch #4.
- remove unused regulators and pinctrl settings for patch #5.
- add new modification for aliases change patch #6.

Changes for v5:
- rename imx93.dtsi to imx91_93_common.dtsi.
- move imx93 specific part from imx91_93_common.dtsi to imx93.dtsi.
- modify the imx91.dtsi to use imx91_93_common.dtsi.
- add new the imx93-blk-ctrl binding and driver patch for imx91 support.
- add new net patch for imx91 support.
- change node name codec and lsm6dsm into common name audio-codec and
  inertial-meter, and add BT compatible string for imx91 board dts.

Changes for v4:
- Add one imx93 patch that add labels in imx93.dtsi
- modify the references in imx91.dtsi
- modify the code alignment
- remove unused newline
- delete the status property
- align pad hex values

Changes for v3:
- Add Conor's ack on patch #1
- format imx91-11x11-evk.dts with the dt-format tool
- add lpi2c1 node

Changes for v2:
- change ddr node pmu compatible
- remove mu1 and mu2
- change iomux node compatible and enable 91 pinctrl
- refine commit message for patch #2
- change hex to lowercase in pinfunc.h
- ordering nodes with the dt-format tool
