2009-04-27[ARM] pxa: fix issue of muxed GPIO irq_chip functions touching non-muxed GPIOsEric Miao
pxa_gpio_irq_type() and pxa_unmask_muxed_gpio() will touch non-muxed GPIOs (0 and 1 on PXA2xx/PXA3xx) bits in GRERx and GFERx, which is incorrect. Actually, only those bits should get updated if the corresponding bits are set in c->irq_mask as well. Fix this by updating only those relevant bits.

2009-03-26[ARM] pxa: build arch/arm/plat-pxa/mfp.c only when PXA3xx or ARCH_MMP definedEric Miao
arch/arm/plat-pxa/mfp.c is not intended to be use by PXA25x/PXA27x, make it explicit here only for use by PXA3xx or ARCH_MMP. Reported-by: Guennadi Liakhovestski <g.liakhovestski@gmx.de> Reported-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2009-03-23[ARM] pxa: move common GPIO handling code into plat-pxaEric Miao
1. add common GPIO handling code into [arch/arm/plat-pxa] 2. common code in <mach/gpio.h> moved into <plat/gpio.h>, new processors should implement its own <mach/gpio.h>, provide the following required definitions and '#include <plat/gpio.h>' in the end: - GPIO_REGS_VIRT for mapped virtual address of the GPIO registers' physical I/O memory - macros of GPLR(), GPSR(), GPDR() for constant optimization for functions gpio_{set,get}_value() (so that bit-bang code can still have tolerable performance) - NR_BUILTIN_GPIO for the number of onchip GPIO - definitions of __gpio_is_inverted() and __gpio_is_occupied(), they can be either macros or inlined functions Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-23[ARM] pxa: introduce plat-pxa for PXA common code and add DMA supportEric Miao
1. introduce folder of 'arch/arm/plat-pxa' for common code across different PXA processor families 2. initially moved DMA code into plat-pxa 3. common code in <mach/dma.h> moved into <plat/dma.h>, new processors should implement its own <mach/dma.h>, provide the following required definitions and '#include <plat/dma.h>' in the end: - DMAC_REGS_VIRT for mapped virtual address of the DMA registers' physical I/O memory Signed-off-by: Eric Miao <eric.miao@marvell.com>
