# Vendor kernel:
# - https://github.com/armbian/linux-rockchip/blob/rk-6.1-rkr5.1/arch/arm64/boot/dts/rockchip/rk3588-mixtile-core3588e.dts
#   - mostly works, still sucks as it's vendor kernel
#   - mainline u-boot can boot the vendor kernel just fine
# Mainline kernel:
# - https://github.com/Joshua-Riek/linux/blob/v6.7-rk3588/arch/arm64/boot/dts/rockchip/rk3588-mixtile-core3588e.dts
#   - a _lot_ of fixes and additions done on top; gpu/npu/i2c/thermals/etc

# Hardware notes:
# - With the LEETOP carrier board (as shipped by Mixtile)
#   - Recovery "button" (NOT real "Maskrom"): "jumper cap to connect the FCREC and GND pins"; this depends on u-boot actually working (not bricked)
#   - OTG/Maskrom port is micro-USB port
#   - The "real" maskrom is to short two tiny solder-joints near the SoC on the SoM; see https://dh19rycdk230a.cloudfront.net/app/uploads/2023/11/solder-joints.png
# - Pinout of the LEETOP carrier board: https://www.cnx-software.com/wp-content/uploads/2023/12/Leetop-A206-40-pin-GPIO-header-pintout.png
#   - pin 1 is 3.3v; pin 6 and 9 and 25 are GND;
#   - pin 3 is SDA; pin 5 is SCL --> i2c-5 confirmed (mainline kernel) // i2c-1 confirmed (vendor kernel)
#   - pin 27 is SDA; pin 28 is SCL --> unconfirmed
#   - pin 8 is UART TX; pin 10 is UART RX --> uart1 unconfirmed
