ARM: sa1100: register clocks early
commit 198b51e8a6a31d3a6f8e9dd9cade3635d0291f26 upstream. Since we switched to use pxa_timer, we need to provide the OSTIMER0 clock. However, as the clock is initialised early, we need to provide the clock early as well, so that pxa_timer can find it. Adding the clock to the clkdev table at core_initcall() time is way too late. Move the initialisation earlier. Fixes: ee3a4020f7c9 ("ARM: 8250/1: sa1100: provide OSTIMER0 clock for pxa_timer") Acked-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
