4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Robert Jarzmik <robert.jarz...@free.fr>
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.
Fixes: fe7710fae477 ("clk: add pxa25x clock drivers")
Fixes: d40670dc6169 ("clk: add pxa27x clock drivers")
Fixes: 9bbb8a338fb2 ("clk: pxa: add pxa3xx clock driver")
