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 = <4>; brcm,sd_sgentry_align = <4>; Signed-off-by: Chi-hsien Lin <chi-hsien.lin-+wT8y+m8/X5BDgjK7y7TUQ@public.gmane.org> --- drivers/net/wireless/broadcom/brcm80211/brcmfmac/of.c | 7 +++++++ 1 file changed, 7 insertions(+)
