Radxa Zero 2 is a small form factor SBC based on the Amlogic A311D
chipset that ships in a number of eMMC configurations:
- Amlogic A311D (Quad A73 + Dual A53) CPU
- 4GB LPDDR4 RAM
- 32/64/128GB eMMC
- Mali G52-MP4 GPU
- HDMI 2.1 output (micro)
- BCM4345 WiFi (2.4/5GHz a/b/g/n/ac) and BT 5.0
- 1x USB 2.0 port - Type C (OTG)
- 1x USB 3.0 port - Type C (Host)
- 1x micro SD Card slot
- 40 Pin GPIO header

Fix the dts to match board's reference design:
- update vddio_boot regulator to 3.3v (Wi-Fi SDIO module)
- add vccq_1v8 regulator with 1.8v for eMMC SDIO
In the first revision of JetHub D1 the vccq_1v8 regulator was 3.3v.
All installed eMMC modules were tested to work in HS200 mode at 3.3v
supply voltage. In the next revisions of the device eMMC will be
powered with 1.8v according to the standard.
* JetHome: Update u-boot patches: fix emmc work on JetHub D1
* JetHome: update kernel patches with last updates for JetHub devices.
* JetHome: Update Bluetooth init script to more stable start.
- starting from Home Assistant OS (HASSOS) setup/patchset, which is stable with pure-mainline
- *huge thanks* to Stefan Agner (@agners) from Home Assistant for his work and help with this
- CONFIG_DRM_MESON=y fixes the order of shutdown callbacks, allowing it to reboot without patches
- this increases the kernel size a bit, due to some dependencies like DRM=y
- remove the shutdown revert patch, allowing other meson64 boards to mainline-reboot
- add fdt/no-map patch fixing the dreaded "SError Interrupt on CPU4" panics that plagued the N2
- move the N2 to mainline u-boot on current (rebased, already done)
- add SPI-enabling DTB variants, which allow writing to SPI NOR flash (and usage instructions in comments)
- add UBOOT_TARGET_MAP and write_uboot_platform_mtd to current, for nand-sata-install to SPI/USB goodness
- remove the UHS-enabling patch, to avoid 1.8v vs 3.3v mess. Make sure to use only A1-rated SD cards as recommended.
- change default cpufreq governor for 24h+ stability
- other patch cleanups:
- move deprecated/non-applying patch to need-check
- remove the HardKernel ODROID-specific reboot driver and DTS patches (odroid-reboot.c) which are now useless.
- remove documentation-only patches (we have enough patches in meson64 without those)
- remove duplicated SAR ADC patches
- remove multiple different and conflicting patches for DTS and emulated-PWM GPIO fan
- now using simple on/off GPIO fan at 30 celsius, unrelated to passive cooling
* Add support for Radxa Zero
u-boot: new patch based on v2021.04
kernel: use patches sent to kernel list by chewitt
Tested with minimal build and cinnamon desktop:
- SD/eMMC, ok
- USB3, works in USB 2 mode
- HDMI, ok
- WiFi/BT, ok

* Add build targets
* Cleanup and set min speed to 666000
* Change to WIP target
Support status undetermined

* [ meson64 ] nanopi K2 ethernet fix
Fix NanoPi K2 Ethernet issues
Do some cleanup of the Meson64 folder while at it
* [ Meson64 ] revert accidental delete of C2 audio patch
- add mtd-utils to PACKAGE_LIST_BOARD.
- this should be enough to wipe Petitboot;
- more investigative work and u-boot building is needed for SPI+SATA boot

A long story short:
- patch 'meson64_add_shutdown_function_to_meson_drv.patch' (adds meson_drv_shutdown) added on 04/03/2021
- same patch renamed to '.patch_disabled' on 07/03/2021, since it broke what it was supposed to fix
- kernel 5.10.24 upstream merged similar version of patch, which indeed fixed some khadas stuff, but broke odroid, at least HC4
- now I add this patch to revert upstream.
- also remove the .patch_disabled to avoid confusion
- to say the truth, the HC4 is not reboot-proof, it still hangs sometimes. so this is not the end of it.
- ps: without this revert, HC4 hangs 100% of the time.
- ps2: did not test on edge 5.11 yet, but it looks like the same
