[PATCH] arm64: zynqmp: Add support for kr260 revA/B boards

Wed May 18 12:49:26 CEST 2022
From: Michal Simek <michal.simek at xilinx.com>
Board is using kv260 design for couple of parts defined by spec like i2c
eeproms, ina260, uart, etc.
Board has 4 gems. One gem connected via PS SGMII(GT), another PS RGMII(MIO)
and 2 via EMIO. First two shares the same MIO lines for PHYs. PL based one
have separate EMIO lines via PL.
Also two USB 3.0 with usb hubs are present. USB phys and USB hubs should
have separate reset line. The first usb0 hub also has USB-SD controller
(usb2244) connected to port 0.
To test compatibility with k26 you can run:
fdtoverlay -o /tmp/output.dtb -i arch/arm/dts/zynqmp-sm-k26-revA.dtb \
arch/arm/dts/zynqmp-sck-kr-g-revA.dtbo
Also add support for kr260-revB board. Based on FRU it is revision B
but schematics can be label as revA03.
Changes in revB are:
- SFP light
- GEM2/3 TX_CLK fixes
- PMOD/RPI connector fixes
- Replace si5332 with oscilators
