Move the processor specific initialization (largely resources initialization) out of soc_common_drv_pcmcia_probe() into dedicated sa11xx_drv_pcmcia_probe() and __pxa2xx_drv_pcmcia_probe(). By doing this, we are now able to move the PCMCIA related definitions out of pxa-regs.h and back into pxa2xx_base.c. As a result, remove that reference of _PCMCIA1IO in arch/arm/mach-pxa/viper.c.

pxa-regs.h and hardware.h are not intended for use directly in driver code, remove those unnecessary references. Signed-off-by: NEric Miao <eric.miao@marvell.com>

The only things prevent drivers/serial/pxa.c from being generic enough are: 1. IER_UUE which can be safely replaced by UART_IER_UUE as defined in serial_reg.h for PXA 2. __PREG() and FFUART/BTUART/STUART definitions to decide the UART port name And removed the un-necessary #include of <mach/...> and <asm/...> headers.

Let's handle GPIOs by banks, each bank covers up to 32 GPIOs with one set of registers, and each set of registers start from different offsets. GPLR GPDR GPSR GPCR GRER GFER GEDR BANK 0 - 0x0000 0x000C 0x0018 0x0024 0x0030 0x003C 0x0048 BANK 1 - 0x0004 0x0010 0x001C 0x0028 0x0034 0x0040 0x004C BANK 2 - 0x0008 0x0014 0x0020 0x002C 0x0038 0x0044 0x0050 BANK 3 - 0x0100 0x010C 0x0118 0x0124 0x0130 0x013C 0x0148 BANK 4 - 0x0104 0x0110 0x011C 0x0128 0x0134 0x0140 0x014C BANK 5 - 0x0108 0x0114 0x0120 0x012C 0x0138 0x0144 0x0150 NOTE: BANK 3 is only available on PXA27x and later processors. BANK 4 and 5 are only available on PXA935 1. introduce GPIO_BANK(n) for the offset base of each bank 2. 'struct pxa_gpio_chip' is expanded to include IRQ edge and mask setings, and saved register values as well, and is dynamically allocated due to possible bank number ranging from 3 to 6 3. all accesses to GPIO registers are made through 'regbase' within 'pxa_gpio_chip', and register offset 4. introduce several inline functions to simplify the code a bit 5. change IRQ demux handler to base on gpio chips Signed-off-by: NMike Rapoport <mike@compulab.co.il> Signed-off-by: NEric Miao <eric.miao@marvell.com>

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: NEric Miao <eric.miao@marvell.com>

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: NEric Miao <eric.miao@marvell.com>

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: NEric Miao <eric.miao@marvell.com>

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: NEric Miao <eric.miao@marvell.com>
