[PATCH net-next v2 1/2] brcmfmac: add new dt entries for SG SDIO settings

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

 



There are 3 fields in SDIO settings (quirks) to workaround some of
the SG SDIO host particularities, i.e higher align requirements for
SG items.
All coding is done the long time ago, but there is no way to change the
driver behavior without patching the kernel.
Add missing devicetree entries.
