Subject: [PATCH] brcmfmac: Add sg parameters dts parsing
Date: Fri, 1 Dec 2017 01:55:50 -0600 [thread overview]
Message-ID: <20171201075542.GA31376@aremote07.aus.cypress.com> (raw)
broken_sg_support, sd_head_align, and sd_sgentry_align are used in
brcmfmac code but not configurable in dts file. Add the parsing logic.
Now they can be configured like below in dts:
brcm,broken_sg_support;
brcm,sd_head_align = /bits/ 16 <4>;
brcm,sd_sgentry_align = /bits/ 16 <4>;
