2012-11-29video: exynos_dp: Reset and initialize DP before requesting irqAjay Kumar
If DP is not reset properly before kernel bootup(in bootloader code), there can be few pending interrupts, and sometimes they invoke DP irq handler as soon as the irq handler is registered in DP probe. So, we make the DP driver more robust by resetting and initializing DP at the earliest and then registering the irq handler.

2012-11-27OMAPDSS: add dss_get_core_pdev()Tomi Valkeinen
Add dss_get_core_pdev() which returns the platform device for dss core device. The following patches use the core pdev to register sysfs files in the compat code. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2012-11-27OMAPDSS: DISPC: pass pclk & lclk to dispc_ovl_calc_scalingTomi Valkeinen
In order to make the scaling calculations independent of the current hardware configuration (e.g. which manager is connected to this output), we need to change the calc funcs to get all the variables needed for the calculations via parameters. This patch changes dispc_ovl_calc_scaling to get pclk and lclk as parameters. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2012-11-27OMAPDSS: DISPC: pclk & lclk rates for writebackTomi Valkeinen
Change the dispc_plane_pclk_rate and dispc_plane_lclk_rate functions to return 0 if the given plane is the writeback plane. The clocks are not valid for WB, but returning 0 from these functions instead of running into BUG() will simplify the code that uses these functions.

2012-11-27OMAPDSS: DISPC: use WARN_ON() in dispc_mgr_goTomi Valkeinen

2012-11-27OMAPDSS: cleanup WB enable/is_enabled functionsTomi Valkeinen

2012-11-27OMAPDSS: DISPC: Remove blocking code from dispc_wb_enable()Tomi Valkeinen
WB will not be used with compat-mode, i.e. from omapfb. This means we don't need the current complex dispc_wb_enable function, but can have a simple register write version of the function. This patch removes all the extra code from dispc_wb_enable() Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-11-27OMAPDSS: DISPC: use get_framedone_irq in disable_digit_outTomi Valkeinen
dispc_mgr_disable_digit_out() needs to wait until the DIGIT output is turned off. This is done with either VSYNC irq on OMAP2/3 and FRAMEDONETV on OMAP4+. It currently uses a rather hacky way to decide what irq to use. This patch changes dispc_mgr_disable_digit_out to use dispc_mgr_get_framedone_irq to find out if there's framedone irq on this SoC, and if not, uses VSYNC. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-11-27OMAPDSS: DISPC: add no_framedone_tv featTomi Valkeinen
OMAP2/3 do not have FRAMEDONETV irq, but later omaps do. We currently always return 0 from dispc_mgr_get_framedone_irq() for TV output to be compatible with OMAP2/3. This patch implements "no_framedone_tv" dispc-feature that is used in dispc_mgr_get_framedone_irq to return either 0 for OMAP2/3, or the correct IRQ number for FRAMEDONETV on OMAP4+. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-11-27OMAPDSS: don't WARN if there's no DSI deviceTomi Valkeinen
dsi_get_dsidev_from_id() gives a WARN if DSI support is not compiled in. This warning is not right, as it's valid to call dsi_get_dsidev_from_id() to see if there is DSI support or not. Remove the WARN(). Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2012-11-27OMAPDSS: DPI: fix crash with dpi_verify_dsi_pll()Tomi Valkeinen
If the DSI support has not been compiled in or the SoC doesn't have DSI hardware, dpi_get_dsidev() returns NULL. This NULL is passed to dpi_verify_dsi_pll() causing a crash. The bug was added with commit 0e8276ef75f5c7811b038d1d23b2b42c16efc5ac (OMAPDSS: DPI: always use DSI PLL if available). Fix this by checking if dsidev is NULL before calling dpi_verify_dsi_pll().

2012-11-26drivers/video: fsl-diu-fb: store EDID data in the global objectTimur Tabi
Although the DIU driver creates five framebuffer devices, only the first one controls the physical display. The remaining four are virtual "AOIs". Therefore, the EDID data should be stored in the global fsl_diu_data object, instead of the per-framebuffer object. Signed-off-by: Timur Tabi <timur@freescale.com>
2012-11-26drivers/video: fsl-diu-fb: don't touch registers for unused featuresTimur Tabi
We don't use the writeback buffer, so don't initialize the registers for that feature. The default value for SYN_POL is already zero, so don't re-initialize it. Writing the INT_STATUS register does nothing. The value that we write to the PLUT register only makes sense on the MPC8610 and P1022, so don't touch that register on the MPC5121.

We also improve the way that interrupts are enabled. Also implement a work-around for broken U-Boots that leave the DIU interrupts enabled. Signed-off-by: Timur Tabi <timur@freescale.com>
2012-11-26drivers/video: fsl-diu-fb: add support for set_gamma ioctlsTimur Tabi

2012-11-26drivers/video: fsl-diu-fb: simplify platforms that have only one portTimur Tabi
