Subject: [PATCH] net: dsa: mt7530: fix support for MT7531BE
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
There are two variants of the MT7531 switch IC which got different
|
||
features (and pins) regarding port 5:
|
||
* MT7531AE: SGMII/1000Base-X/2500Base-X SerDes PCS
|
||
* MT7531BE: RGMII
|
||
|
||
Moving the creation of the SerDes PCS from mt753x_setup to mt7530_probe
|
||
with commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation
|
||
to mt7530_probe function") works fine for MT7531AE which got two
|
||
instances of mtk-pcs-lynxi, however, MT7531BE requires mt7531_pll_setup
|
||
to setup clocks before the single PCS on port 6 (usually used as CPU
|
||
port) starts to work and hence the PCS creation failed on MT7531BE.
|
||
|
||
Fix this by introducing a pointer to mt7531_create_sgmii function in
|
||
struct mt7530_priv and call it again at the end of mt753x_setup like it
|
||
was before commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS
|
||
creation to mt7530_probe function").
|
||
|
||
Fixes: 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation to mt7530_probe function")
