2011-03-22sisfb: add support for XGI Z9 DDR2 POSTAaro Koskinen1-9/+68
Add support for ZGI Z9 DDR2 POST. The init sequence is from XGI's xgifb driver. Tested with ARM board using a PCI card with XGI Z9s and 32 MB DDR2 memory. After a cold reset the POST succeeds.

2011-03-22sisfb: POST should fail if R/W test failsAaro Koskinen1-5/+17
Currently there is no indication if R/W test fails during POST. This can happen e.g. when user plugs in a card with unsupported type of memory. Since the driver will be unusable, it's better to fail the whole POST if the memory cannot be configured properly.

2011-03-21matroxfb: remove incorrect Matrox G200eV supportGary Hade1-9/+0
Remove incorrect Matrox G200eV support that was previously added by commit e3a1938805d2e81b27d3d348788644f3bad004f2 A serious issue with the incorrect G200eV support that reproduces on the Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login banner, login prompt, etc) on the console when X is not running and total lack of text on all of the virtual consoles after X is started. Any concerns that the incorrect code (upstream since October 2008) has been successfully used on non-IBM G200eV equipped system(s) appear to be unwarranted. In addition to the serious/non-intermittent nature of issues that have been spotted on IBM systems, complete removal of the incorrect code is clearly supported by the following Matrox (Yannick Heneault) provided input: "It impossible that this patch should have work on a system. The patch only declare the G200eV as a regular G200 which is not case. Many registers are different, including at least the PLL programming sequence. If the G200eV is programmed like a regular G200, it will not display anything." v1 - Initial patch that removed the incorrect code for _all_ G200eV equipped systems. v2 - Darrick Wong provided patch that blacklisted the incorrect code on G200eV equipped IBM systems leaving it enabled on all G200eV equipped non-IBM systems. v3 - Same code changes included with v1 plus additional justification for complete removal of the incorrect code.

2011-03-18OMAP: DSS2: Implement OMAP4 DSS fclk supportMurthy, Raghuveer1-12/+22
Add dss.dpll4_m4_ck (DSS FCLK) initialization for OMAP4. This is used to compute the pixel clock for DPI interface and also to reconfigure the DSS FCLK to the desired rate, corresponding to the rate computed for pixel clock. Adding these cpu_is_44xx() checks are meant to be temporary, until a cleaner implementation to manage these checks are added. Currently this is needed to get DVI display running on OMAP4 PandaBoard Signed-off-by: Raghuveer Murthy <raghuveer.murthy@ti.com> [tomi.valkeinen@ti.com: minor changes due to conflicts] Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-03-18OMAP: DSS2: Clean up for dpll4_m4_ck handlingTomi Valkeinen1-34/+59
OMAP2 does not have dpll4_m4_ck source clock for dss functional clock, but later OMAPs do. Currently we check for cpu type in multiple places to find out if dpll4_m4_ck is available. This patch cleans up dss.c by using the fact that dss.dpll4_m4_ck pointer is NULL on OMAP2. This allows us to remove many of the cpu checks. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-03-16ARM: pxafb: rework pxafb overlay memory managementVasily Khoruzhick2-43/+81
PXAFB overlay memory management is something messy: - it allocates memory dynamically on open/release, and it results in memory allocation failure after ~1h of uptime (system does not have 115k of physically contiguous memory) - in release callback it tries to free memory even if it was not allocated. Also driver touches FDADR1 on main plane reconfiguration, and it can cause problems if overlay1 is enabled. This patch attempts to fix those issues. Patch is based on Russell King's work.

2011-03-16fbdev: sh_mobile_lcdc: Add YUV framebuffer supportDamian Hobson-Garcia2-29/+114
Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats (bpp = 12, 16, and 24) respectively. When double-buffering both Y planes appear before the C planes (Y-Y-C-C), as opposed to Y-C-Y-C. Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use .bpp to distiguish between the 3 modes. The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and should be set accordingly. .nonstd must be set to 0 for RGB mode. Due to the encoding of YUV data, the framebuffer will clear to green instead of black. In YUV 420 mode, panning is only possible in 2 line increments. Additionally in YUV 420 mode the vertical resolution of the framebuffer must be an even number.
