Subject: ARM: sa1100: register clocks early
From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx>
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")
