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.

Subject: [PATCH] brcmfmac: Remove brcmf_sdiod_addrprep()
This function has become trivial enough that it may as well be pushed into
its callers, which has the side-benefit of clarifying what's going on.
Remove it, and rename brcmf_sdiod_set_sbaddr_window() to
brcmf_sdiod_set_backplane_window() as it's easier to understand.

Subject: [PATCH] brcmfmac: remove unnecessary call to
brcmf_sdiod_set_backplane_window()
All functions that might require the window address changing call
brcmf_sdiod_set_backplane_window() prior to access. Thus resetting
the window is not required.

Subject: [PATCH] brcmfmac: Remove repeated calls to brcmf_chip_get_core()
There is no need to repeatdly call brcmf_chip_get_core(), which
traverses a list of cores every time its called (including during
register access code!).
Call it once, and store a pointer to the core structure. The existing
code does nto keep track of users of the cores anyway, and even so, this
will allow for easier refcounting in future.
