Subject: ARM: dts: i.MX27: Increase "clock-latency" value
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8defcb5376993b30b7852de6e827498370a8123d;p=deliverable%2Flinux.git

ARM: dts: i.MX27: Increase "clock-latency" value

i.MX27 CPU can be clocked with a 32 kHz quartz, and not just 32768 Hz,
so increase "clock-latency" value, which will ensure that we use two
clock cycles on frequency change.
