This patch adds warning about changing EPLL rate to notice that other driver that controls H/W, which is using EPLL, will has unknown effects by this EPLL rate change.
Signed-off-by: Seungwhan Youn sw.youn@samsung.com --- This patch is re-worked to avoid conflict with previous re-worked patch( [PATCH v3 1/6] ARM: S5P: Reduce duplicated EPLL control codes).
This patch also depends on previous v1 and v2 petch-set which was accepted, and depends on re-workd patch v3 1/6. -- arch/arm/mach-s5p64x0/clock-s5p6440.c | 3 +++ arch/arm/mach-s5p64x0/clock-s5p6450.c | 3 +++ arch/arm/mach-s5pc100/clock.c | 3 +++ arch/arm/mach-s5pv210/clock.c | 3 +++ 4 files changed, 12 insertions(+), 0 deletions(-)
