If anyone has any objections, please let me know. ------------------ From: Robert Jarzmik commit 4b5fb7dc9096d949a22651370bb6bf11f21edb30 upstream. Legacy drivers which are not yet ported, such as cpufreq-pxa[23]xx, rely on pxaXXx_get_clk_frequency_khz() to find the CPU core frequency. This reporting was broken because the expected unit is kHz and not Hz. Fix the reporting for pxa25x, pxa27x and pxa3xx.
