2011-03-18OMAP: DSS2: Implement OMAP4 DSS fclk supportMurthy, Raghuveer
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 Valkeinen
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 Khoruzhick
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-Garcia
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.

2011-03-11OMAP4: DSS2: Clock source changes for OMAP4Taneja, Archit
On OMAP3, the pixel clock for the LCD manager was derived through DISPC_FCLK as: Lcd Pixel clock = DISPC_FCLK / lcd / pcd Where lcd and pcd are divisors in the DISPC_DIVISOR register. On OMAP4, the pixel clocks for LCD1 and LCD2 managers are derived from 2 new clocks named LCD1_CLK and LCD2_CLK. The pixel clocks are calculated as: Lcd_o Pixel clock = LCDo_CLK / lcdo /pcdo, o = 1, 2 Where lcdo and pcdo registers are divisors in DISPC_DIVISORo registers. LCD1_CLK and LCD2_CLK can have DSS_FCLK, and the M4 divider clocks of DSI1 PLL and DSI2 PLL as clock sources respectively. Introduce functions to select and get the clock source for these new clocks. Modify DISPC functions get the correct lck and pck rates based on the clock source of these clocks. Since OMAP2/3 don't have these clocks, force OMAP2/3 to always have the LCD_CLK source as DSS_CLK_SRC_FCK by introducing a dss feature. Introduce clock source names for OMAP4 and some register field changes in DSS_CTRL on OMAP4. Currently, LCD2_CLK can only have DSS_FCLK as its clock source as DSI2 PLL functionality hasn't been introduced yet. BUG for now if DSI2 PLL is selected as clock.
