Message-Id: <20201207125627.30843-5-m.grzeschik@pengutronix.de>

Subject: [PATCH v5 4/6] net: dsa: microchip: ksz8795: add support for ksz88xx chips
We add support for the ksz8863 and ksz8873 chips which are
using the same register patterns but other offsets as the
ksz8795.
Signed-off-by: Michael Grzeschik <m.grzeschik@...gutronix.de>
---
v1 -> v4: - extracted this change from bigger previous patch
v4 -> v5: - added clear of reset bit for ksz8863 reset code
- using extra device flag IS_KSZ88x3 instead of is_ksz8795 function
- using DSA_TAG_PROTO_KSZ9893 protocol for ksz88x3 instead
