Subject: [PATCH v2 3/3] ARM: dts: Add Geniatech XPI-3128 RK3128 board
XPI-3128 is RK3128 based SBC form Geniatec in RPi form factor
Specs:
- Rockchip RK3128
- 512MB/1 GB DDR3 DRAM
- 8/16 GB eMMC
- TF card slot
- 100 MBit ethernet / RJ45 (TI DP83848C phy)
- optional Marvell 88W8897 (USB version)
- 3 x USB host (onboard GL852G hub connected to SoC ehci host)
- 1 x USB otg
- 1 x Type-C (solely for powering the board)
- HDMI 1.4 out
- ADC button
- IR receiver
- Artasie AM1805 RTC
- 40 pin header
