Subject: [PATCH 8/8] net: stmmac: dwmac-stm32: add management of stm32mp13 for
|
||
|
|
stm32
|
||
|
|
|
||
|
|
Add Ethernet support for STM32MP13.
|
||
|
|
STM32MP13 is STM32 SOC with 2 GMACs instances.
|
||
|
|
GMAC IP version is SNPS 4.20.
|
||
|
|
GMAC IP configure with 1 RX and 1 TX queue.
|
||
|
|
DMA HW capability register supported
|
||
|
|
RX Checksum Offload Engine supported
|
||
|
|
TX Checksum insertion supported
|
||
|
|
Wake-Up On Lan supported
|
||
|
|
TSO supported
