2012-01-03drivers/video: fsl-diu-fb: merge fsl_diu_alloc() into map_video_memory()Timur Tabi1-36/+11
Functions fsl_diu_alloc() and fsl_diu_free() were only being called by map_video_memory() and unmap_video_memory(), respectively. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2012-01-03drivers/video: fsl-diu-fb: add default platform ops functionsTimur Tabi1-3/+61
The DIU driver requires some platform-specific functions to be defined, but two them can be optional because most platforms implement them the same way. Functions set_gamma_table() and get_pixel_format() are only needed because of quirks in the Freescale MPC8610 HPCD reference board. For other boards, a generic implementation works, so we shouldn't require the platform code to define them.

2012-01-03drivers/video: fsl-diu-fb: remove broken reference count enabling the displayTimur Tabi1-10/+2
The functions enable_lcdc() and disable_lcdc() used the variable fb_enable to keep a reference count of when the display is enabled, but the code is broken. The display is always disabled when disable_lcdc(), and it is always enabled when enable_lcdc() is called, regardless of the value of fb_enable. Obviously, we don't need to keep a reference count, so just remove the variable. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2012-01-03drivers/video: fsl-diu-fb: set correct framebuffer flagsTimur Tabi1-1/+2
The DIU uses system RAM for the framebuffer, so FBINFO_VIRTFB should be set. Since the framebuffer is in system RAM, it can be read from more quickly than written to, so FBINFO_READS_FAST should be set. We can also set FBINFO_PARTIAL_PAN_OK for the same reasons.

2012-01-03offb: Fix setting of the pseudo-palette for >8bppBenjamin Herrenschmidt1-24/+20
When using a >8bpp framebuffer, offb advertises truecolor, not directcolor, and doesn't touch the color map even if it has a corresponding access method for the real hardware. Thus it needs to set the pseudo-palette with all 3 components of the color, like other truecolor framebuffers, not with copies of the color index like a directcolor framebuffer would do. This went unnoticed for a long time because it's pretty hard to get offb to kick in with anything but 8bpp (old BootX under MacOS will do that and qemu does it).

2012-01-03offb: Add palette hack for qemu "standard vga" framebufferBenjamin Herrenschmidt1-4/+15
We rename the mach64 hack to "simple" since that's also applicable to anything using VGA-style DAC IO ports (set to 8-bit DAC) and we use it for qemu vga. Note that this is keyed on a device-tree "compatible" property that is currently only set by an upcoming version of SLOF when using the qemu "pseries" platform. This is on purpose as other qemu ppc platforms using OpenBIOS aren't properly setting the DAC to 8-bit at the time of the writing of this patch. We can fix OpenBIOS later to do that and add the required property, in which case it will be matched by this change. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

2012-01-02OMAPDSS: DISPC: Update Scaling Clock LogicChandrabhanu Mahapatra3-20/+54
Clock requirements for scaling in OMAP2, OMAP3 and OMAP4 are different. In OMAP2 and OMAP3 the required clock rate is a function of pixel clock, vertical downscale ratio and horizontal downscale ratio whereas in OMAP4 it is a function of pixel clock and horizontal downscale ratio only. Selection of 3-tap vs 5-tap coefficients depends on clock rate line buffer width in OMAP3 whereas in OMAP4 it is independent of clock rate and line buffer width. In OMAP2 3-tap for vertical and 5-tap for horizontal scaling is used. In OMAP4 5-tap is used both for horizontal and vertical scaling for better performance. Also, the number and width of line buffers differs in OMAP3 and OMAP4. So, clock functions have been fined tuned for OMAP3 and support has been added added for OMAP4. This code has been tested on OMAP2, OMAP3 and OMAP4, and scaling issues due to clock errors have been resolved.

2012-01-02OMAPDSS: DISPC: Update Fir CoefficientsChandrabhanu Mahapatra4-119/+357
The FIR coefficients present in kernel are being updated to new coefficients consisting of 24 coefficient tables, with 12 each for 3 tap and 5 tap scenario, which are chosen on the basis of DISPC up/downsampling filters M value. M is the inverse of low pass cut off frequency of the sampling filter. For vertical scaling 3 tap or 5 tap tables are used based on the clock rate and width of the line buffer whereas in OMAP2 3 tap is always used. For horizontal scaling however 5 tap tables are always used. New coefficients and the corresponding logic have been tested on OMAP2, OMAP3 and OMAP4. Horizontal and vertical scaling worked fine except for some 3 tap vs 5 tap issue during vertical upscaling and clock failing issues which is acknowledged in the next patch. Vertical upscaling was found to perform better under 5 taps. The 24 coefficient tables have been moved to another file dispc_coefs.c for proper maintainance. This code is written based on code written by Lajos Molnar <lajos@ti.com> in Android Kernel for scaling. Lajos Molnar <lajos@ti.com> had fine tuned the FIR coefficient selection process and reduced outliness and blockiness around images when upscaling more than 2 times.

2011-12-19video: s3c-fb: modify runtime pm functionsJingoo Han1-31/+20
Runtime suspend and runtime resume are modified in order to reduce the complexity and improve the usability of runtime pm. After probe function, s3c-fb driver is not suspended until suspend or remove is called. The scheme is changed as follows: runtime_get is only called in probe and resume. runtime_put is only called in remove and suspend. open/close cannot call the runtime_get/put. Also, runtime_susepnd/resume are just called by runtime pm, not doing suspend/resume routine any longer. This is because open/close cannot call the runtime_get/put; the suspend/resume routine in runtime_suspend/resume were previously used when open and close were called. The name of s3c-fb dev_pm_ops is changed from s3cfb_pm_ops to s3c_fb_pm_ops in order to use more consistent naming.

2011-12-19drivers/video: fsl-diu-fb: merge all allocated data into one blockTimur Tabi1-184/+136
The Freescale DIU driver allocates multiple blocks of memory, including multiple DMA buffers. Merge all of these blocks into one data structure. Specifically: 1) struct fsl_diu_data now contains everything that needs to be allocated, except for the framebuffers themselves. DMA'able objects are aligned correctly within the structure. 2) struct diu_addr is no longer needed, because we don't have to manage multiple blocks of DMA memory. 3) Since there's no diu_addr any more, macro DMA_ADDR is used to calculate the DMA address of any field in fsl_diu_data. 4) Functions allocate_buf() and free_buf() are no longer needed, because we now assume that dma_alloc_coherent() will allocate a page-aligned block, and everything is properly aligned with fsl_diu_data already, so we no longer need to align any memory blocks ourselves. 5) The "dummy" area descriptor is now defined separately from the other five ADs, so NUM_AOIS (previously called FSL_AOI_NUM) is now set to five instead of six. Previously, all six were combined together to avoid a separate call to allocate_buf() just for the dummy AD. 6) framebuffer_alloc() and framebuffer_release() are no longer used. The framebuffer is initialized manually. 7) Error handling is simplified since there's only one memory buffer allocated.

2011-12-08video i.MX IPU: Fix display connectionsSascha Hauer1-39/+22
The IPU internally works on 32bit colors. It can arbitrarily map between pixel formats and internal representation and also between internal representation and the physical connection to the display. The driver used to change the mapping between internal representation and display connection depending on the user selected bpp which is wrong. Instead, the mapping is specified by the hardware, so an additional field in platform data is added to describe the connection between i.MX and the display. The default for this field is RGB666 which seems to be the only configuration which works without this patch, so I assumed that all in Kernel boards are connected this way. This patch has been tested on a RGB666 connected display and a RGB888 connected display in both 16bpp and 32bpp modes.
