#6010 new defect

vlan capabilities of ADM6996FC switch not controllable on RouterSation ar71xx platform

Reported by: doddel Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: adm6996 ar71xx vlan Cc:


although the adm6996fc is capable of having the switch outputs separated as vlan, swconfig and config/network settings have no effect. Activating in trunk config_adm6996_phy=y makes the RouterStation unaccessible via ethernet. Also the two lan interfaces loose their auto-polarity capability and seem only to operate at 10 Mbps to judge from the leds.

this issue remains as of trunk r18858 on kernel

ADM6996FC has a little different with ADM6996F , the major is that pin 59 (SDC/SDIO Mode Selection)
32 Bits Mode
1B 16 Bits Mode. Same timing as MDC/MDIO.

WHILE ADM6996F is 1B for 32 Bits Mode....

a detail as follow:
Pin No. ADM6996FC/FCX ADM6996F Notes
59 P5TXD3(SDIO_MD) P5TXD3(VOL23) For ADM6996FC/FCX, SDIO_MD=0 default 32bit

For ADM6996M, SDIO_MD=0 default 16bit mode
Add pull-up/down resistor for ADM6996F/FC/M
compatible design to avoid wrong power-on-latch.

60 P5TXD2(RMIISEL) P5TXD2(ROMCODE25 Add pull down resistor for ADM6996F/FC/M P5 MII

) mode to avoid wrong power-on-latch.

61 P5TXD1(7WIRE) P5TXD1(P5GPSI) Add pull down resistor for ADM6996F/FC/M P5 MII

mode to avoid wrong power-on-latch.

65 INT_N VCCIK(1.8V Digital) Interrupt for Learning Table Access/Port

Security/Counter Overflow/Port Status
Add a option design to CPU INT_N pin

we can keep compatible by pull down pin 60/61 and connect pin 65 to VCC 1.8v, however the major pin 59 is a problem, maybe changed the driver is enough, but , anybody can tell me how to patch the code?
