Raw Blame History

From 71bd508d7ded8c504ef05d1b4befecfe25e54cb1 Mon Sep 17 00:00:00 2001
From: Ian Molton <ian@mnementh.co.uk>
Date: Fri, 8 Dec 2017 13:10:29 +0100
Subject: [PATCH] brcmfmac: Rename / replace old IO functions with simpler
ones.
Primarily this patch removes:
brcmf_sdiod_f0_writeb()
brcmf_sdiod_reg_write()
brcmf_sdiod_reg_read()
Since we no longer use the quirky method of deciding which function to
address via the address being accessed, take the opportunity to rename
some IO functions more in line with common kernel code. We also convert
those that map directly to sdio_{read,write}*() to macros.
