2008-04-19[ARM] pxa: rename mfp.c to mfp-pxa3xx.c to indicate it's pxa3xx specificeric miao

2008-04-19[ARM] pxa: make pxa_gpio_irq_type() processor genericeric miao
The main issue here is that pxa3xx does not have GAFRx registers, access directly to these registers should be avoided for pxa3xx: 1. introduce __gpio_is_occupied() to indicate the GAFRx and GPDRx registers are already configured on pxa{25x,27x} while returns 0 always on pxa3xx 2. pxa_gpio_mode(gpio | GPIO_IN) is replaced directly with assign- ment of GPDRx, the side effect of this change is that the pin _must_ be configured before use, pxa_gpio_irq_type() will not change the pin to GPIO, as this restriction is sane, esp. with the new MFP framework Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-04-19[ARM] pxa: merge assignment of set_wake into pxa_init_{irq,gpio}()eric miao
To further clean up the GPIO and IRQ structure: 1. pxa_init_irq_gpio() and pxa_init_gpio() combines into a single function pxa_init_gpio() 2. assignment of set_wake merged into pxa_init_{irq,gpio}() as an argument Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-04-19[ARM] pxa: integrate low IRQ chip (ICIP) and high IRQ chip (ICIP2) into oneeric miao
This makes the code better organized and simplified a bit. The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}. Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2008-04-19[ARM] pxa: cleanup the coding style of pxa_gpio_set_type()eric miao

2008-04-19[ARM] pxa: make GPIO IRQ code less dependent on the internal IRQseric miao
by: 1. introduce dedicated pxa_{mask,unmask}_low_gpio() 2. remove set_irq_chip(IRQ_GPIO_2_x, ...) which has already been initialized in pxa_init_irq() 3. introduce dedicated pxa_init_gpio_set_wake() Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-04-19[ARM] pxa: generalize the muxed gpio IRQ handling code with loop and ffs()eric miao
1. As David Brownell suggests, using ffs() is going to make the loop a bit faster (by avoiding unnecessary shift and iteration) 2. Russell suggested find_{first,next}_bit() being used with the gedr[] array Signed-off-by: eric miao <eric.miao@marvell.com> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
