* [ARM] pxafb: add palette format support for LCCR4_PAL_FOR_3Eric Miao2008-12-291-0/+1
| | | | | | | | | | Add the palette format support for LCCR4_PAL_FOR_3, and fix the issue of LCCR4 being never assigned. Also remove the useless pxafb_set_truecolor(). Signed-off-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Eric Miao <ycmiao@ycmiao-hp520.(none)>
* [ARM] pxafb: add support for FBIOPAN_DISPLAY by dma brachingEric Miao2008-12-291-2/+8
| | | | | | | | | | | | | | | dma branching is enabled by extending the current setup_frame_dma() function to allow a 2nd set of frame/palette dma descriptors to be used. As a result, pxafb_dma_buff.dma_desc[], pxafb_dma_buff.pal_desc[] and pxafb_info.fdadr[] are doubled. This allows maximum re-use of the current dma setup code, although the pxafb_info.fdadr[xx] for FBRx register values looks a bit odd.

* [ARM] pxafb: allow video memory size to be configurableEric Miao2008-12-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The amount of video memory size is decided according to the following order: 1. <xres> x <yres> x <bits_per_pixel> by default, which is the backward compatible way 2. size specified in platform data 3. size specified in module parameter 'options' string or specified in kernel boot command line (see updated Documentation/fb/pxafb.txt) And now since the memory is allocated from system memory, the pxafb_mmap can be removed and the default fb_mmap() should be working all right. Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA descriptors and palettes, the allocation can be separated cleanly. NOTE: the LCD DMA actually supports chained transfer (i.e. page-based transfers), to simplify the logic and keep the performance (with less TLB misses when accessing from memory mapped user space), the memory is allocated by alloc_pages_*() to ensures it's physical contiguous.

* [ARM] rtc-sa1100: don't assume CLOCK_TICK_RATE to be a constantEric Miao2008-12-295-9/+31
| | | | | | | | | | | | As Nicolas and Russell pointed out, CLOCK_TICK_RATE is no more a constant on PXA when multiple processors and platforms are selected, change TIMER_FREQ in rtc-sa1100.c into a variable. Since the code to decide the clock tick rate is re-used from timer.c, introduce a common get_clock_tick_rate() for this.

* [ARM] pxa: initial support for the Imote2 platformJonathan Cameron2008-12-174-1/+584
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes made as suggested by Eric Miao (including fix to map_io silly mistake!). Originally designed by Intel, now sold by Crossbow (www.xbow.com). Very little actually on board. The patch includes sensors and similar as found on commonly occurring daughter boards. Some of the drivers are not in mainline as yet as they are either part of the IIO subsystem or need a lot of work before submission. What is the position wrt to putting them in i2c board configs etc? Support for these boards has been maintained outside the kernel for a long time, but now that there is a good da9030 pmic driver available the last major hurdle no longer exists. All comments welcomed. The Imote2's big brother (stargate2) will follow once any problems with this one have been cleaned up and a few bits and bobs have been added to the da903x driver. Hopefully the cc2420 driver will get cleaned up and submitted in the not too distant future as well.

* [ARM] pxafb: allow insertion of delay to the smart panel command sequenceEric Miao2008-12-171-0/+7
| | | | | | | | | | | Some smart panel requires a delay between command sequences, while PXA LCD controller didn't provide such one, let's emulate this by software. A software delay marker can be inserted into the command sequence, once pxafb_smart_queue() detects this, it flushes the previous commands and delay for a specified number of milliseconds.

* [ARM] pxafb: allow better platform configurable smart panel timingEric Miao2008-12-171-0/+4

| | | | | | | | | | | | | Change the halt and reboot method from gpio based to "jump to ROM IPL beginning". This gives control back to IPL, which without PowerOn key pressed, will put the device into deep sleep until PowerOn is pressed for 1 second. But this has the benefit of keeping the RTC registers across reboots, which is good for OS change.

It also cures the runtime warning that was printed each time the frequency was changed. Got rid of all references to CPUFREQ_POLICY_* for pxa255, and sticked with the run/turbo thing.
