* [ARM] pxa: move pxa_gpio_mode() outside of generic gpio.cEric Miao2009-03-09
| | | | | | | | Looks like we have to live with pxa_gpio_mode() for a while, giving its presence is actually making gpio.c not generic enough, let's move it temporarily outside before it can be fully purged. Signed-off-by: Eric Miao <eric.miao@marvell.com>
* [ARM] pxa: move IRQ handling of GPIO 0 and 1 outside of gpio.cEric Miao2009-03-09
| | | | | | | | | | | | | | | This is part of the work making gpio.c generic enough, the changes include: 1. move IRQ handling of GPIO 0 and 1 outside (and back into irq.c) 2. pxa_init_gpio() accepts a range for muxed GPIO IRQs, and an IRQ number for the muxed GPIOs 3. __gpio_is_occupied() and __gpio_is_inverted() are made inline, and are moved into <mach/gpio.h> instead of generic gpio.c Signed-off-by: Eric Miao <eric.miao@marvell.com>
* [ARM] pxa: move DMA registers definitions into <mach/dma.h>Eric Miao2009-03-09
| | | | | | | | | | | | | | 1. Driver code where pxa_request_dma() is called will most likely reference DMA registers as well, and it is really unnecessary to include pxa-regs.h just for this. Move the definitions into <mach/dma.h> and make relevant drivers include it instead of <mach/pxa-regs.h>. 2. Introduce DMAC_REGS_VIRT as the virtual address base for these DMA registers. This allows later processors to re-use the same IP while registers may start at different I/O address. Signed-off-by: Eric Miao <eric.miao@marvell.com>

* [ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usageEric Miao2009-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Considering the header mess ATM, it is not always possible to include the correct header files within board code. Let's keep this simple: <mach/pxa25x.h> - for pxa25x based platforms <mach/pxa27x.h> - for pxa27x based platforms <mach/pxa300.h> - for pxa300 based platforms <mach/pxa320.h> - for pxa320 based platforms <mach/pxa930.h> - for pxa930 based platforms NOTE: 1. one header one board file, they are not compatible (i.e. they have conflicting definitions which won't compile if included together). 2. Unless strictly necessary, the following header files are considered to be SoC files use _only_, and is not recommended to be included in board code: <mach/hardware.h> <mach/pxa-regs.h> <mach/pxa2xx-regs.h> <mach/pxa3xx-regs.h> <mach/mfp.h> <mach/mfp-pxa2xx.h> <mach/mfp-pxa25x.h> <mach/mfp-pxa27x.h> <mach/mfp-pxa3xx.h> <mach/mfp-pxa300.h> <mach/mfp-pxa320.h> <mach/mfp-pxa930.h> Signed-off-by: Eric Miao <eric.miao@marvell.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | We should not be modifying the scatterlist passed to us from the driver code; doing so breaks assumptions made by the DMA API code, and could cause problems if the driver retries a transfer using an old scatterlist.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware supports transfers up to a page boundary per buffer. Currently, we work around that in the DMA code by splitting each buffer up as we run through the scatterlist. Avoid this by telling the block layers about the hardware restriction. Eventually, this will allow us to phase out the splitting code, but not until the old IDE layer allows us to control the value it gives to blk_queue_segment_boundary().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than having the central DMA multiplexer call the architecture specific DMA initialization function, have each architecture DMA initialization function use core_initcall(), and register each DMA channel separately with the multiplexer. This removes the array of dma structures in the central multiplexer, replacing it with an array of pointers instead; this is more flexible since it allows the drivers to wrap the DMA structure (eventually allowing us to transition non-ISA DMA drivers away.)
