2009-03-19[ARM] pxa: fix overlay being un-necessarily initialized on pxa25xEric Miao
pxa25x doesn't support overlay in its LCD controller, this patch adds pxafb_overlay_supported() functions to check the initialization is necessary. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-19[ARM] pxa: make second argument of clk_add_alias a name instead of the deviceDmitry Eremin-Solenikov
clk_add_alias is commonly called for platform devices that are not yet registered in the device tree. Thus the clock alias is associated with NULL device name. Fix this by passing the device name instead of just device pointer. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2009-03-13[ARM] pxa: fix typo in BANK_OFF() macro in gpio.hEric Miao
The typo was originally fixed by Mike Rapoport and missed. And is later reported by Matthias Meier. Signed-off-by: Matthias Meier <matthias.j.meier@gmx.net> Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2009-03-09[ARM] pxa: separate definitions from pxa-regs.h and remove it finallyEric Miao
The remaining registers are separated into: - <mach/regs-ost.h> - <mach/regs-rtc.h> - <mach/regs-intc.h> and then we can remove pxa-regs.h completely. Instead of #include this file, let's: 1. include the specific <mach/regs-*.h> with care (if that's absolutely necessary) 2. define the registers in the driver, make cleanly defined API to expose the register access to external with sufficient reason Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: move pxa2xx chip selects definitions out of pxa-regs.hEric Miao
The definitions of PXA_CS<x>_PHYS are really PXA2xx specific and should be moved out of pxa-regs.h. As an illustration, the PXA3xx static chip selects definitions are added into pxa3xx-regs.h. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: make lubbock specific debugging stuffs back into lubbock.cEric Miao
This isn't perfect but at least solves the problem of pm.c's dependency on register definitions in <mach/lubbock.h>, which doesn't make much sense. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: move PCMCIA definitions out of pxa-regs.h into pxa2xx_base.cEric Miao
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. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: remove unnecessary #include of pxa-regs.h and hardware.hEric Miao
pxa-regs.h and hardware.h are not intended for use directly in driver code, remove those unnecessary references. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: remove machine class specific stuffs from serial driverEric Miao
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. Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: access GPIO registers by chip so to make it further genericEric Miao
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: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: move declaration of 'pxa_last_gpio' into <mach/gpio.h>Eric Miao
Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: move GPIO register definitions into <mach/gpio.h>Eric Miao
This makes gpio.c fully independent of pxa-regs.h (except for the virtual address of the registers). Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Eric Miao <eric.miao@marvell.com>
2009-03-09[ARM] pxa: move pxa_gpio_mode() outside of generic gpio.cEric Miao
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>
2009-03-09[ARM] pxa: move IRQ handling of GPIO 0 and 1 outside of gpio.cEric Miao
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>
2009-03-09[ARM] pxa: move DMA registers definitions into <mach/dma.h>Eric Miao
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>
2009-03-09[ARM] pxa: allow DMA controller IRQ being specifiedEric Miao

2009-03-09[ARM] pxa: introduce pxa{25x,27x,300,320,930}.h for board usageEric Miao
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>

2009-02-21[ARM] dma: RiscPC: don't modify DMA SG entriesRussell King
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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
