+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 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.
