From: Rafał Miłecki Date: Tue, 19 Jan 2016 07:45:25 +0000 (+0100) Subject: bcma: use _PMU_ in all names of PMU registers X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=67edf354faaf93156646e741483b2313bc756c0f;p=linux-beck.git bcma: use _PMU_ in all names of PMU registers PMU (Power Management Unit) seems to be a separated piece of hardware, just accessed using ChipCommon core registers. In recent Broadcom chipsets PMU is not bounded to CC but available as separated core. To make code cleaner & easier to review (for a correct R/W access) use clearer names.
