2010-05-02ARM: 5890/1: Fix incorrect Realview board IRQs for L220 and PMUWill Deacon3-16/+7
In anticipation of PMU support for Realview boards, the IRQs defined for some of these boards need updating. This patch removes incorrect L220 IRQ definitions, corrects incorrect PMU IRQs and adds any missing IRQs that are required.

2010-05-02ARM: Integrator: move 16-bit timer support to Integrator/APRussell King4-163/+155
Only Integrator/AP has 16-bit timers, so move the support into the Integrator/AP specific support files. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-05-02ARM: Integrator: convert Integrator/CP to use SP804 timer supportRussell King2-2/+13
The Integrator/CP board has SP804-compatible timer modules, so use the SP804-compatible code from Versatile and Realview. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-05-02ARM: Realview/Versatile: remove useless TIMER_RELOAD calculationsRussell King1-11/+1
Realview/Versatile copied the Integrator timer code, including the calculations for ensuring that the reload value fits into the 16-bit counter. 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>

2010-05-02ARM: ICST: kill duplicate icst codeRussell King20-218/+67

2010-05-02ARM: ICST: icst.*_ps_to_vco() functions are unused, remove themRussell King4-131/+0
These functions were originally implemented for the CLCD driver before we had clk API support. Since the CLCD driver does not use these anymore, we can remove them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2010-04-29ARM: 5943/1: iop: n2100: enable serial interruptAaro Koskinen1-1/+1
Thecus N2100 has a jumper (J3/J4) to select whether the XINT1 interrupt line is connected to the second UHCI controller (position J3) or to the serial port UART (position J4). Currently, the kernel is hardcoded to assume the J3 position, and the serial port is always being used in polling mode. The patch adds the IRQ autodetection flag for the serial port interrupt, and also marks it as shared (as the driver for the second UHCI controller will request the interrupt in any case). Now, when the jumper is set to the J4 position, the serial port will have an interrupt line, resulting in less CPU overhead and faster throughput.

2010-04-14ARM: remove unnecessary cache flushRussell King1-2/+0
This cache flush occurs when we first insert a page into the page tables, where a page did not exist previously. There can be no cache lines associated with this virtual mapping, so this cache flush is redundant.

This patch allows using a kernel image compressed with LZMA on ARM.
