[PATCH v4 3/7] ARM: S5P: Added default pll values for APLL 800/1000MHz

flat view
STALE5932d

From: myungjoo.ham@samsung.com (MyungJoo Ham)
Date: 2010-07-22 09:22:49
Also in: linux-samsung-soc
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

CPUFREQ of S5PV210 uses different APLL settings according to
different CPU frequencies. We provide such settings values for
CPUFREQ at pll.h.

Note that at 1GHz of ARMCLK, APLL should be 1GHz and for other lower
ARMCLK, APLL should be 800MHz.
