The WLAN + WED reset sequence relies on being able to receive interrupts from
the card, in order to synchronize individual steps with the firmware.
When WED is stopped, leave interrupts running and rely on the driver turning
off unwanted ones.
WED DMA also needs to be disabled before resetting.

Subject: [PATCH net-next 3/3] net: ethernet: mtk_wed: move dlm a dedicated dts
|
|
node
|
|
|
|
Since the dlm memory region is not part of the RAM SoC, move dlm in a
|
|
deidicated syscon node.
|
|
This patch helps to keep backward-compatibility with older version of
|
|
uboot codebase where we have a limit of 8 reserved-memory dts child
|
|
nodes.
|
|
Keep backward-compatibility with older dts version where dlm was defined
|
|
as reserved-memory child node.
