2015-02-04OMAPDSS: DPI: DRA7xx supportTomi Valkeinen
Add support for DRA7xx DPI output. DRA7xx has three DPI outputs, each of which gets its input from a DISPC channel. However, DRA72x has only one video PLL, and DRA74x has two video PLLs. In both cases the video PLLs need to be shared between multiple outputs. The driver doesn't handle this at the moment. Also, DRA7xx requires configuring CONTROL module bits to route the clock from the PLL to the used DISPC channel. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-02-04OMAPDSS: HDMI: Add DRA7xx supportTomi Valkeinen

2015-02-04OMAPDSS: Add Video PLLs for DRA7xxTomi Valkeinen
DRA7xx SoCs have one (DRA72x) or two (DRA74x) video PLLs. They are basically the same as DSI PLLs on OMAPs, but without the rest of the DSI hardware. The video PLLs also require some configuration via the CONTROL module. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

This register configures whether the PLL registers are accessed internally by DSS, or externally using OCP2SCP interface. They also configure muxes which route the PLL output to a particular LCD overlay manager within DSS. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2015-02-04OMAPDSS: encoder-tpd12s015: Fix race issue with LS_OETomi Valkeinen
A race issue has been observed with the encoder-tpd12s015 driver, which leads to errors when trying to read EDID. This has only now been observed, as OMAP4 and OMAP5 boards used SoC's GPIOs for LS_OE GPIO. On dra7-evm boards, the LS_OE is behind a i2c controlled GPIO expander, which increases the time to set the LS_OE. This patch simplifies the handling of the LS_OE gpio in the driver by removing the interrupt handling totally. The only time we actually need to enable LS_OE is when we are reading the EDID, and thus we can just set and clear the LS_OE gpio inside the read_edid() function. This also has the additional benefit of very slightly decreasing the power consumption. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2015-02-04OMAPDSS: OMAP5: fix digit output's allowed mgrsTomi Valkeinen
The OMAP5 HW supports directing DIGIT channel to DPI output, but the driver doesn't support that. However, we have marked that configuration as possible in the dss features, so in certain cases the driver tries to use that configuration, leading to broken display. Fix the problem by allowing DIGIT channel to go only to HDMI output. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2015-01-27fbdev: fix CVT vertical front and back porch valuesTomi Valkeinen
CVT v1.1 spec says: "the vertical front porch shall in all cases be fixed to 3 lines". The code in fbcvt.c instead sets the _back_ porch to 3 (plus margin). After swapping cvt.v_front_porch and cvt.v_back_porch the resulting timings were in line with CVT timings in VESA DMT spec. The bug seems to be more than 9 years old, but I presume it has not been noticed as usually the video timings come from the EDID or from the timing tables in fbdev, and probably swapped values for vfp and vbp work fine for most of the displays.

2015-01-15video: fbdev: Validate mode timing against monspecDavid Ung
fbmon may generate mode timings that are out of spec of the monitor. eg DELL U2410 has a max clock 170mhz but advertises a resolutions of 1920x1200@60 in its Standard Timings using 2byte code of D1 00. When this is looked up in the DMT table it gives it a 193mhz clock. Although the DELL monitor supports 1920x1200@60, it can only run with reduced timings at 154mhz or DMT id 0x44 which has no STD 2byte code. This patch checks to see if the mode can be supported by the monitor by comparing against monspecs.dclkmax.

2014-12-29video/logo: prevent use of logos after they have been freedTomi Valkeinen
If the probe of an fb driver has been deferred due to missing dependencies, and the probe is later ran when a module is loaded, the fbdev framework will try to find a logo to use. However, the logos are __initdata, and have already been freed. This causes sometimes page faults, if the logo memory is not mapped, sometimes other random crashes as the logo data is invalid, and sometimes nothing, if the fbdev decides to reject the logo (e.g. the random value depicting the logo's height is too big). This patch adds a late_initcall function to mark the logos as freed. In reality the logos are freed later, and fbdev probe may be ran between this late_initcall and the freeing of the logos. In that case we will miss drawing the logo, even if it would be possible. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: stable@vger.kernel.org
