[PATCH v3 2/8] arm64: zynqmp: Add support for Xilinx zcu100-revC
Michal Simek
michal.simek at xilinx.com
Fri Mar 2 11:04:28 PST 2018
This board has 2GB of memory, i2c, sd, wifi sdio, spis, uarts, display
port and usbs.
Board is using fixed clocks because clock driver hasn't been merged yet.

Changes in v3:
- Remove usb and gpio aliases
Changes in v2:
- Use i2c-mux instead of i2cswitch
- Remove i2c mw u-boot commands
- Use 96boards labels for i2cs and spis
- Fix pmic and wifi node
- Record compatible string to xilinx.txt
- Remove Nathalie's email (she left Xilinx already)
