Hi,
the switch in the BCM5357 needs a special configuration. Does your SoC
have the chipid 0x5356? Then the robo core rev is 3.
This is part of the robo switch driver:
if (robo->corerev < 3) {
val32 |= ((1 << 20) | /* valid write */
((vid >> 4) << 12)); /* vlan id bit[11:4] */
} else {
val32 |= ((1 << 24) | /* valid write */
(vid << 12)); /* vlan id bit[11:4] */
}
Could you try the attached patch on your device.
