[PATCH v3 3/8] arm64: zynqmp: Add support for Xilinx zcu102

Michal Simek michal.simek at xilinx.com
Fri Mar 2 11:04:29 PST 2018


This patch is adding revA, revB and rev1.0. There are also other
revisions between which should be backward compatible with previous
versions. Unfortunately all revs are still in use.

---

Changes in v3:
- Use i2c-mux instead of i2cswitch on revB board
- Remove qspi comment from revB
- Remove gpio and usb aliases

Changes in v2:
- Remove i2c mw u-boot commands
- Use i2c-mux instead of i2cswitch
- Use clock generator without numbers.
- Use dash in node name zcu102 rev1.0
- Record compatible string to xilinx.txt
