From d650471a399e65e423967e0b7692c86228211522 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sun, 20 Jul 2014 13:38:58 +0200 Subject: sparcspkr: use sbus_*() primitives for IO The memory are mapped using of_ioremap() which is an indication this is sbus memory. Shift all uses of inb/outb to the sbus variants. The inb/outb methods uses ASI_PHYS_BYPASS_EC_E_L, whereas sbus_ variants uses ASI_PHYS_BYPASS_EC_E. The difference is if the reads/writes are done in native or little endian. But for byte reads/writes there is no difference so this does not matter for inb/outb - and this driver only uses the byte variants. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
