The TRONFY MXQ comes with either 1GB or 2GB RAM. Both variants share (like most boards based on Amlogic reference designs): - 10/100 PHY (IC Plus IP101GR) with GPIOH_4 being the reset line and GPIOH_3 the interrupt line - SD card slot with the card detection GPIO at CARD_6 - VCCK is generated by PWM_C with a period of 1148ns and XTAL as input clock - USB OTG exposed on one of the USB-A connectors - 4-port USB hub with 3 ports exposed to the outside There seem the multiple board revision out there according to various forum posts: - storage: eMMC or NAND flash - wifi: Ampak AP6210 or Realtek 8189 Add support for the following functionality: - SoC temperature (hwmon) - changing the CPU voltage - Ethernet connectivity - SD card - USB Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> --- arch/arm/boot/dts/meson8b-mxq.dts | 139 ++++++++++++++++++++++++++++++ 1 file changed, 139 insertions(+)
