From bc30b2b225a31f7fcf4e25014a73739641a8df71 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Tue, 24 Dec 2013 16:48:03 -0500 Subject: cpu/allwinner/a10: Refactor API for gating clocks to peripherals Rather than having to track which bit in which register should be cleared or set to gate or ungate the clock to a certain peripheral, provide a simplified enum which encodes the register and bit. This change comes with a function which decodes the enum and gates/ungates the clock. This also removes the register-dependent bitmasks for APB0 and APB1 gating registers.
