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 GPIO register definitions into <mach/gpio.h>Eric Miao

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: 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>

2009-01-19[ARM] pxa: fix NAND and MMC clock initialization for pxa3xxMike Rapoport
After commit 8c3abc7d903df492a7394b0adae4349d9a381aaf ("[ARM] pxa: convert to clkdev and match clocks by struct device where possible") get_clk in pxa3xx_nand fails with -ENOENT. Apparently, clk_get in pxamci will also fail for MCI2 on PXA310. The 'clk_find' and therefore 'clk_get' require driver to supply both 'dev_id' and 'con_id' if they are not NULL in the 'strcut clk_lookup', but neither pxa3xx_nand nor pxamci supply 'con_id'. This patch sets 'con_id' to NULL in NAND clock and MCI2 clock registration. Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Eric Miao <eric.miao@marvell.com>

2008-12-29[ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devicesEric Miao
PXA27x and later processors support overlay1 and overlay2 on-top of the base framebuffer (although under-neath the base is also possible). They support palette and no-palette RGB formats, as well as YUV formats (only available on overlay2). These overlays have dedicated DMA channels and behave in a similar way as a framebuffer. This heavily simplified and re-structured work is based on the original pxafb_overlay.c (which is pending for mainline merge for a long time). The major problems with this pxafb_overlay.c are (if you are interested in the history): 1. heavily redundant (the control logics for overlay1 and overlay2 are actually identical except for some small operations, which are now abstracted into a 'pxafb_layer_ops' structure) 2. a lot of useless and un-tested code (two workarounds which are now fixed on mature silicons) 3. cursorfb is actually useless, hardware cursor should not be used this way, and the code was actually un-tested for a long time. The code in this patch should be self-explanatory, I tried to add minimum comments. As said, this is basically simplified, there are several things still on the pending list: 1. palette mode is un-supported and un-tested (although re-using the palette code of the base framebuffer is actually very easy now with previous clean-up patches) 2. fb_pan_display for overlay(s) is un-supported 3. the base framebuffer can actually be abstracted by 'pxafb_layer' as well, which will help further re-use of the code and keep a better and consistent structure. (This is the reason I named it 'pxafb_layer' instead of 'pxafb_overlay' or something alike) See Documentation/fb/pxafb.txt for additional usage information.

2008-12-29[ARM] pxafb: cleanup of the color format manipulation codeEric Miao
1. introduce var_to_depth() to calculate the color depth including the transparency bit 2. the conversion from 'fb_var_screeninfo' to LCCR3 BPP bits can be re- used by overlays (in OVLxC1), thus an individual pxafb_var_to_bpp() has been separated out. 3. pxafb_setmode() should really set the color bitfields correctly at begining, introduce a pxafb_set_pixfmt() for this 4. allow user apps to specify color formats within fb_var_screeninfo, and checking of this in pxafb_check_var() has been simplified as below: a) pxafb_var_to_bpp() should pass - which means a basically correct bits_per_pixel and color depth setting b) the RGBT bitfields are then forced into supported values by pxafb_set_pixfmt() Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Eric Miao <ycmiao@ycmiao-hp520.(none)>
