2007-10-12[ARM] 4590/1: ns9xxx: add gpio handling functionsUwe Kleine-König
This implementation conforms to the general GPIO API introduced in 2.6.21. This patch was signed-of by David Brownell before I exported the functions using EXPORT_SYMBOL. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-10-12[ARM] 4589/1: ns9xxx: acknowledge IRQ_EXT2 in the demux routine for FPGA irqsUwe Kleine-König
The FPGA on the a9m9750dev board interrupts the CPU via EXT2. So to acknowledge any FPGA interrupt IRQ_EXT2 must be acknowledged. Signed-off-by: Uwe Kleine-König <ukleinek@informatik.uni-freiburg.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-10-12[ARM] Add rtc-cmos driver for ISA-based footbridge platformsRussell King
... but the rtc-cmos is rather broken; if PNP is enabled, it assumes that we have ACPI (!) which is quite bogus on these platforms - which may have ISAPNP but not ACPI. Something to be solved in the future. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-10-12[ARM] 4585/1: Correctly identify the CPU architecture versionCatalin Marinas
The cpu_architecture() function in arch/arm/kernel/setup.c only works with cores produced by ARM Ltd. The more generic approach is to read the ID_MMFR0 register and check for the VMSA or PMSA version supported. With this patch, the ARM11MPCore would be reported as ARMv7 since its MMU is compatible with ARMv7.

2007-10-12[ARM] 4581/1: Fix the conditional execution of the NWFPE instructionsCatalin Marinas
Starting with ARMv7-A, conditional execution of undefined instructions can trigger an exception even if the condition check fails. This patch modifies the NWFPE support to check the condition before emulating the instruction.

2007-10-12[ARM] 4539/1: clocksource and clockevents for at91rm9200David Brownell
GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200. - Oneshot mode (used for NO_HZ and high res timers) uses the alarm to emulate a real oneshot timer; the trickiest bit is how to avoid some lowlevel races. Thanks to Remy Bohmer for various fixes to this code. - Tighten up periodic mode support using the PIT. - Streamline reads of the 32KHz counter. Thanks to Marc Pignat for some testing results: the CRTR register has *very* odd behavior. The reread appears to work around stranger glitches than just getting an old clock value (which would quickly self-correct). - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100), since that no longer acts correct (time increases too fast). Note that the at91sam9 and at91x40 chips need other solutions, since they don't have the same system timer module.

2007-09-13[ARM] 4567/1: Fix 'Oops - undefined instruction' when CONFIG_VFP=y on non ↵Tzachi Perelstein
VFP device vfp_init() takes care of the condition when CONFIG_VFP=y but no real VFP device exists. However, when this condition is true, a compiler might misplace code lines in a way that will break this support. (To be more specific - fmrx(FPSID) might be executed before vfp_testing_entry assignment, which will end up with Oops - undefined instruction).

As pointed out by Jrgen, we are overflowing the number of GPIOs in pxa_init_irq_gpio(). I'm seeing the same problem on my HTC Universal PXA270 based PDA. According to Eric, the function argument is the number of GPIOs, so we should keep the semantics and reduce the number of iteration by 1.
