transition to use it. viafb_shared should contain all general, non-surface specific data that should be shared along all viafb framebuffers while viafb_par should only contain things that are specific to each surface or in other words extend fb_info. This change is intended to clean the dual/multi framebuffer handling up. This removes the annoyance that viafbinfo1->par points to a different structure than viaparinfo1. As the last change is fundamental it is difficult to ensure that all parts of the driver do not depend on the previous brokenness but the chance of regressions is very low. Signed-off-by:

the register are written with reserved values. This makes the display go white in some configurations and not usable until the framebuffer is removed. It's better to not initialize it as it allows to use a previously (by BIOS) correctly configured display. This patch makes some displays work but might cause problems on others. This is bad but can not be easily avoided. If this causes some regressions it's probably the best to fix it in the 'active' display setup code. Signed-off-by:

influence the driver operation. This patch does change the userspace behaviour as it removes two IOCTLs and one module parameter. But this is good as it removes useless stuff and helps the user to figure out the options that do affect the driver behaviour (which are still too many). Signed-off-by:

were made: info->screen_base - viafb_FB_MM (VRAM offset calculation) was replaced by info->fix.smem_start - viafbinfo->fix.smem_start which is essentially the same calculation but done with physical instead virtual addresses. *->fbmem_virt was replaced by viafbinfo->screen_base This is true for viafbinfo and viafbinfo1 as the par pointers are equal. An early initialization of viafbinfo1->fix.smem* was removed as done later in viafb_setup_fixinfo. This patch highlights that the only usage of the ioremapped video memory in the driver is for hardware cursor handling. Even if it has to hold the used virtual screen mapped for old-fashioned read/write calls (vs. mmap'ed) a lot virtual memory could be saved by only ioremapping on demand. Code cleanup, no runtime changes expected. Signed-off-by:

instead. This is possible because horizontal and vertical address are the same as horizontal and vertical resolution. The reduced blanking modes in the table are no problem because they have a higher index than the normal modes and therefore always the normal modes are selected just as the old behaviour.

viafb_set_secondary_address and make it more flexible to reuse it for panning. Using central functions makes it easier to follow HW manipulations. Remove crt locking as it should be only needed for timing manipulation. Move iga_path manipulation to via_pci_probe. Remove memset for screen cleaning as it is currently done only for the second screen. This is not needed for normal operation but has a little chance of causing unwanted display artifacts. This can be fixed later more consistent and more efficient (using viafb_fillrect) if needed. This is a code clenup, no notable runtime changes expected. Signed-off-by:

data in viafb_par. Use the relevant data of fb_info instead. On the way it removes an inconsistency in handling a second framebuffer which only worked because viafbinfo1->par is modified to point to the same viafb_par as viafbinfo->par. Code cleanup only, no runtime change expected. Signed-off-by:

viafb_setmode is called. This is not done consistently along graphic cores and not even the whole address but often only parts of it. On top of that it seems useless as the real/final address will be set by viafb_set_start_addr a few lines later. Remove this superfluous initalization to shrink register initalization and as a start to decouple primary and secondary display. Code cleanup, no notable runtime change expected. Signed-off-by:

missing break as discovered by Harald Welte. As CX700 and VX800 have exactly the same register initialization we can use one for both to avoid duplicated code. As this is a pure code cleanup no measurable runtime effects are expected. Signed-off-by:

a. An if loop check while returning from lcd_disable_raster() function has been removed. b. "invert_pxl_clock" variable has been renamed as "invert_pxl_clk" and moved from lcd_ctrl_config structure in include/video/da8xx-fb.h file to da8xx_panel structure in drivers/video/da8xx-fb.c file. Appropriate changes in source code as a result of moving this variable has also been done.

LCDC specifications can be found at http://www.ti.com/litv/pdf/sprufm0a. LCDC on DA8xx consists of two independent controllers, the Raster Controller and the LCD Interface Display Driver (LIDD) controller. LIDD further supports character and graphic displays. This patch adds support for the graphic display (Sharp LQ035Q3DG01) found on the DA830 based EVM. The EVM details can be found at: http://support.spectrumdigital.com/boards/dskda830/revc/.

Rebecca took over and (re)wrote the bulk of the driver, getting things stable for production ship of Dream and Sapphire, and Dima is currently adding support for later Qualcomm chipsets (QSD8x50, etc).
