[PATCH 2/2] can:ti_hecc: board specific hookup on AM3517EVM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add board specific hookup for TI HECC driver on
AM3517 EVM

Signed-off-by: Sriramakrishnan <srk@xxxxxx>
Acked-by: Anant Gole <anantgole@xxxxxx>
---
The driver requires that CAN_STB signal be driven low to enable
CAN PHY. Currently this is being managed from U-boot. Will submit a patch
for handling this as part of board init sequence.
