2013-09-26OMAPDSS: Add missing dependency on backlight for DSI-CM panel drierMark Brown

2013-09-19OMAPDSS: DISPC: set irq_safe for runtime PMTomi Valkeinen
We have a bug with omapdrm, where omapdrm calls dispc's pm_runtime function in atomic context, and dispc's pm_runtime is not marked as irq_safe: BUG: sleeping function called from invalid context at drivers/base/power/runtime.c:952 Dispc's runtime PM callbacks are irq safe, so we can just set the irq_safe flag to fix the issue. However, in the long term, I'd rather have omapdrm manage the runtime PM calls in a better way. Calling get/put for every small operation that touches the dispc registers is very inefficient. It'd be better and cleaner to have clear "in-use" and "not-in-use" states for dispc, so that we don't need to do register context restore for small operations, only to turn dispc off right afterwards.

2013-09-19OMAPDSS: Return right error during connector probeSathya Prakash M R
While using HDMI connector driver with sil9022 encoder came across issue where connector driver is probed first. This resulted in error. A deffered probe solved this. Most connector drivers need a encoder driver as their video source. This patch ensures we do a probe defferal if video source is not present for connector drivers.

2013-08-30OMAPDSS: rename omap_dss_device's 'device' field to 'dst'Tomi Valkeinen
In the old panel device model we had omap_dss_output entities, representing the encoders in the DSS block. This entity had "device" field, which pointed to the panel that was using the omap_dss_output. With the new panel device model, the omap_dss_output is integrated into omap_dss_device, which now represents a "display entity". Thus the "device" field, now in omap_dss_device, points to the next entity in the display entity-chain. This patch renames the "device" field to "dst", which much better tells what the field points to. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Archit Taneja <archit@ti.com>
2013-08-30OMAPDSS: rename omap_dss_device's 'output' to 'src'Tomi Valkeinen
In the old panel device model we had "outputs", which were the encoders inside OMAP DSS block, and panel devices (omap_dss_device). The panel devices had a reference to the source of the video data, i.e. reference to an "output", in a field named "output". That was somewhat confusing even in the old panel device model, but even more so with the panel device model where we can have longer chains of display entities.

Commit 5391e87d1259 (OMAPDSS: remove dispc's dependency to VENC/HDMI) introduced a possible NULL reference bug in the HDMI driver when setting timings. In practice the bug shouldn't happen, as the timings have been verified earlier, and thus the timings should always be ok.

2013-08-06OMAPDSS: HDMI: Fix AVI infoframe bugMythri P K
ti_hdmi_4xxx_basic_configure() is supposed to initialize the AVI infoframe data in the ip_data container. However, the function actually takes a copy of the infoframe from the ip_data, and then goes on initializing that copy. The initialized data is never copied back to the ip_data container, thus the infoframe in ip_data is left always zero. Afaik, this doesn't really cause any issues in the current mainline, as we don't use the advanced features offered by the AVI infoframe. This patch fixes the initialization of the AVI infoframe.

connector-analog-tv.c uses omap_dss_pal_timings, defined in omapdss's venc.c, for default timings. omap_dss_pal_timings only exists when VENC is enabled in the kernel config, so disabling VENC breaks omap_dss_pal_timings connector-analog-tv compilation. Instead of adding dependency to VENC, add internal default timings to the connector driver, because the connector driver should not depend on VENC, and it can be used with any other analog TV encoder.

DPI is supposed to skip odd dividers in the clock path when the pixel clock is higher than 100MHz. The code, however, defines the pixel clock limit as 1MHz.

2013-06-17OMAPDSS: public omapdss_register_output()Tomi Valkeinen
In order to allow multiple display block in a video pipeline, we need to give the drivers way to register themselves. For now we have the omapdss_register_display() which is used to register panels, and dss_register_output() which is used to register DSS encoders. This patch makes dss_register_output() public (with the name of omapdss_register_output), which can be used to register also external encoders. The distinction between register_output and register_display is that a "display" is an entity at the end of the videopipeline, and "output" is something inside the pipeline. The registration and naming will be made saner in the future, but the current names and functions are kept to minimize changes during the dss device model transition.
