Subject[PATCH v3 2/5] phy: berlin-sata: Add support for BG2 SATA PHY
Date
Berlin BG2 also has a SATA PHY compatible with the current driver
except different PHY_BASE. Add a new compatible to the driver
reflecting the different PHY_BASE.

Acked-by: Antoine Ténart <antoine.tenart@free-electrons.com>
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>

Changelog:
v1->v2:
- none
v2->v3:
- Use of_device_is_compatible for different PHY_BASE (Suggested by
Felipe Balbi)
