Subject: clock-imx35: fix divider if ahb is source for ipg_per
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c96c1e394fa72bd995154af7143873945a3fa89d;p=deliverable%2Flinux.git

clock-imx35: fix divider if ahb is source for ipg_per

According to the Datasheet:
"i.MX35 (MCIMX35) Multimedia Applications Processor Reference Manual,
Rev. 2" "Table 14-6. PDR0 Field Descriptions" the divider is
CCM_PER_AHB[3:0] + 1.

This patch adds the missing + 1.
