Subject: [PATCH 17/29] net: mediatek: optimize the switch reset delay wait
|
|
time
|
|
|
|
Not all switches requires 1 second delay after deasserting reset.
|
|
MT7531 requires only maximum 200ms.
|
|
|
|
This patch defines dedicated reset wait time for each switch chip, and will
|
|
significantly improve the boot time for boards using MT7531.
