| | * OMAPDSS: DPI: DRA7xx supportTomi Valkeinen2015-02-041-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | * OMAPDSS: encoder-tpd12s015: Fix race issue with LS_OETomi Valkeinen2015-02-041-47/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | fbdev: fix CVT vertical front and back porch valuesTomi Valkeinen2015-01-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When receiving video it is very useful to be able to unpack the InfoFrames. Logging is useful as well, both for transmitters and receivers. Especially when implementing the VIDIOC_LOG_STATUS ioctl (supported by many V4L2 drivers) for a receiver it is important to be able to easily log what the InfoFrame contains. This greatly simplifies debugging.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | IRQ_TYPE_PRIO is no longer used by the Atari platform interrupt code since commit 734085651c9b80aa ("[PATCH] m68k: convert atari irq code") in v2.6.18-rc1, so drop it. Note that its value has been reused for a different purpose (IRQ_TYPE_EDGE_FALLING) since commit 6a6de9ef5850d063 ("[PATCH] genirq: core") in v2.6.18-rc1.

* OMAPDSS: SDI: fix output port_numTomi Valkeinen2014-12-301-0/+2
| | | | | | | | | | | | | | After the commit ef691ff48bc8 (OMAPDSS: DT: Get source endpoint by matching reg-id) we look for the SDI output using the port number. However, the SDI driver doesn't set the port number, which causes the SDI display to not initialize. Fix this by setting the SDI port number to 1. We use a hardcoded value, as SDI was used only on OMAP3 and it's always port number 1 there.

* video/fbdev: fix defio's fsyncTomi Valkeinen2014-12-301-2/+3
| | | | | | | | | | | fb_deferred_io_fsync() returns the value of schedule_delayed_work() as an error code, but schedule_delayed_work() does not return an error. It returns true/false depending on whether the work was already queued. Fix this by ignoring the return value of schedule_delayed_work().

* video/logo: prevent use of logos after they have been freedTomi Valkeinen2014-12-291-1/+16
| | | | | | | | | | | | | | | | | | | | 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
