Subject: [PATCH] net: dsa: qca8k: fix internal delay applied to the wrong PAD
|
|
config
|
|
|
|
With SGMII phy the internal delay is always applied to the PAD0 config.
|
|
This is caused by the falling edge configuration that hardcode the reg
|
|
to PAD0 (as the falling edge bits are present only in PAD0 reg)
|
|
Move the delay configuration before the reg overwrite to correctly apply
|
|
the delay.
|
|
|
|
Fixes: cef08115846e ("net: dsa: qca8k: set internal delay also for sgmii")
