2009-05-07mxc: emulate GPIO interrupt on both-edgesGuennadi Liakhovetski
MXC GPIO controller does not support generation of interrupts on both edges. Emulate this mode in software by reconfiguring the irq trigger polarity on each interrupt. This follows an example of drivers/mfd/asic3.c. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-05-05MXC: remove BUG_ON in interrupt handlerSascha Hauer
On i.MX31 I sometimes get spurious interrupts. There is no need to crash the whole system when this happens. Instead, silently ignore it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13mxc: first set GPIO level, then switch direction to outputGuennadi Liakhovetski
Make sure not to create spurious pulses on GPIOs, when configuring them as output: first set required level, then switch direction. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2008-12-16patch-mxc-add-ARCH_MX1Paulius Zaleckas
Adds MX1 architecture to platform MXC. It will supersede mach-imx and let it die. Signed-off-by: Paulius Zaleckas <paulius.zaleckas@teltonika.lt> Signed-off-by: Darius Augulis <augulis.darius@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2008-10-30[ARM] MXC: Fix mxc_gpio_get(), which must read PSR register instead DR.Darius Augulis
The Data register holds the value we have written to a gpio. To get the input value we must read the Pad Status Register MX3 (or Sample Status register in MX1/2 terms) Signed-off-by: Darius Augulis <augulis.darius@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-07-27[ARM] 5179/1: Replace obsolete IRQT_* and __IRQT_* values with IRQ_TYPE_*Dmitry Baryshkov
IRQT_* and __IRQT_* were obsoleted long ago by patch [3692/1]. Remove them completely.

2008-07-05MXC arch: Add gpio support for the whole platformJuergen Beisert
This patch bases on the one from Daniel Mack. The most important change to Daniel's patch is to be more generic. This gpio routine supports at least the i.MX27 and i.MX31 processors. Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de> Acked-by: Daniel Mack <daniel@caiaq.de>
