| | | | | | | | | * ARM: 5890/1: Fix incorrect Realview board IRQs for L220 and PMUWill Deacon2010-05-02

This patch removes incorrect L220 IRQ definitions, corrects incorrect PMU IRQs and adds any missing IRQs that are required.

However, these platforms have a 32-bit counter which is clocked at a slower rate. The result is that the preprocessor conditions are never triggered: TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than 0x10000. So, remove the unnecessary complexity, reducing the TIMER_RELOAD calculation to just: TICKS_PER_uSEC * mSEC_10 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
