-Subject: [PATCH] arm: sa1100: add cpu clock
-
-Both SA1100 framebuffer and PCMCIA drivers require knowledge of cpu
-frequency to correctly program timings.  Currently they receive timing
-information by calling cpufreq_get(0).  However if cpu frequency driver
-is not enabled (e.g. due to unsupported DRAM chip/board on sa1110)
-cpufreq_get(0) returns 0, causing incorrect timings to be programmed.
-
-Add cpu clock returning cpu frequency, to be used by sa11x0 fb and
-pcmcia drivers.
