Copy the devicetree source for the A20 SoC and all existing boards verbatim from the Linux v5.18-rc1 tag. This commit also adds the following new board devicetrees: - sun7i-a20-haoyu-marsboard.dts - sun7i-a20-linutronix-testbox-v2.dts - sun7i-a20-olinuxino-lime-emmc.dts This update includes changes to the USB PHY detection GPIO properties which are needed to convert that driver to use the DM GPIO framework.
