2014-07-04OMAPDSS: HDMI5: use common AVI infoframe supportTomi Valkeinen
Instead of using OMAP specific AVI infoframe structs, use the common one from include/linux/hdmi.h. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-07-04OMAPDSS: HDMI4: use common AVI infoframe supportTomi Valkeinen
Instead of using OMAP specific AVI infoframe structs, use the common one from include/linux/hdmi.h. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-07-04OMAPDSS: Kconfig: select HDMITomi Valkeinen
Select HDMI support to be able to use HDMI infoframe helpers. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-07-04OMAPDSS: HDMI: fix name conflictTomi Valkeinen
OMAP HDMI driver has an 'enum hdmi_audio_sample_size', which conflicts with the common include/linux/hdmi.h. Change the name of the OMAP specific enum with '_omap" postfix. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-07-04OMAPDSS: DISPC: clean up dispc_mgr_timings_okTomi Valkeinen
dispc_mgr_timings_ok() is a bit confusing how it handles the return value. Change the function to just return immediately when a timing is deemed not valid, making the code much easier to follow. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-07-04OMAPDSS: DISPC: reject interlace for lcd outTomi Valkeinen
OMAP2/3 does not support interlace for LCD out. OMAP4+ does, but is not supported by the driver at the moment. The driver still accepts interlaced mode for LCD out, causing broken display output. This patch makes dispc reject interlace for LCD out. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-07-04OMAPDSS: DISPC: fix debugfs reg dumpTomi Valkeinen
DISPC reg dump prints a few registers twice. Remove the extra prints. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-06-26video: omapdss: Fix potential null pointer dereferenceSachin Kamat
kmalloc can return null. Add a check to avoid potential null pointer dereference error when the pointer is accessed later. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-28OMAPDSS: move 'compatible' converter to omapdss driverTomi Valkeinen
Move the panel/encoder driver compatible-string converter from arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical place for it, as it's really an omapdss internal hack. The code is rewritten to follow the video node graph, starting from omapdss. This removes the need to have the device compatible-string database. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-23OMAPDSS: HDMI: fix devm_ioremap_resource error checksTomi Valkeinen
devm_ioremap_resource returns ERR_PTR on error, not NULL. Fix the error checks in the driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-23OMAPDSS: HDMI: remove unused definesTomi Valkeinen
Remove some unused defines from the HDMI driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-23OMAPDSS: HDMI: cleanup WP ioremapsTomi Valkeinen
Commit 59b3d38a3691396783df108e6afbba30656edccb missed cleaning up the hdmi_wp.c file. Clean up hdmi_wp.c the same way as the others. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2014-05-09OMAPDSS: Fix writes to DISPC_POL_FREQTomi Valkeinen
When omapdss writes to DISPC_POL_FREQ register, it always ORs the bits with the current contents of the register, never clearing the old ones, causing wrong signal polarity settings. As we write all the bits in DISPC_POL_FREQ, we don't need to care about the current contents of the register. So fix the issue by constructing new register value from scratch. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09OMAPDSS: HDMI: cleanup ioremapsTomi Valkeinen
Now that all the boards using OMAP HDMI are using DT boot, we can remove the hacks for getting the ioresources with non-DT boot. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09OMAPDSS: HDMI: Add OMAP5 HDMI supportTomi Valkeinen
This adds a new driver to omapdss for OMAP5 HDMI. However, the new driver uses common HDMI files which are shared with OMAP4 HDMI driver. OMAP5 HDMI has a different HDMI core IP compared to OMAP4, but has very similar PLL and PHY IPs which can be handled with common code. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09OMAPDSS: HDMI: PLL changes for OMAP5Archit Taneja
Add a features struct to differentiate between the HDMI PLLs on OMAP4 and OMAP5. The OMAP5 PLL is more sensitive when it comes to locking. We need to ensure that the DCO freq isn't too low for lower pixel clocks. Modify the PLL computation slightly to ensure the HDMI PLL locks for lower frequencies. This will be later replaced by a more complex computation which makes sure all the PLL constraints are met.

2014-05-09OMAPDSS: HDMI: PHY changes for OMAP5Archit Taneja
OMAP5 HDMI PHY has some differences compared to OMAP4 HDMI PHY. This patch creates a features struct which help the driver configure the PHY based on what SoC it is. Some of the features aren't currenlty used, but will come in use later. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09OMAPDSS: HDMI: support larger register offsets for OMAP5 HDMI coreArchit Taneja
The HDMI core IP on OMAP5 has a wider address range for registers. The offsets for the later registers can't fit into the u16 type currently used for hdmi register read and write functions. Use u32 for offsets instead. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09OMAPDSS: HDMI: move irq & phy pwr handlingTomi Valkeinen
HDMI IRQ handling was moved into hdmi_phy.c when restructuring the HDMI driver. While this worked fine, it's not correct. The HDMI IRQ handling should be either in the hdmi_wp, or in the main hdmi driver. This patch moves the handling to the main hdmi driver, as I feel it's a more appropriate choice. This move also requires changing the handling of the PHY power, as that was partly handled in the IRQ handler. The PHY power is handled via the WP module. An option would be to give HDMI PHY driver function pointers that it could use to manage the PHY power, but as the PHY power is not needed to access the PHY registers, the handling was also moved to the main HDMI driver. This could be changed later if need be. Note that there's slightly similar power issue with the PLL: the HDMI PLLs power is also handled via the WP module. For now, the PLL power handling is still done inside the PLL driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09OMAPDSS: HDMI: improve MakefileTomi Valkeinen
We'll soon add support for OMAP5 HDMI, which uses some of the same files as OMAP4 HDMI does. This patch adds a new config entry "OMAP2_DSS_HDMI_COMMON", which both OMAP4 and OMAP5 HDMI config entries can select. OMAP2_DSS_HDMI_COMMON will cause the common HDMI files to be compiled.

2014-05-09OMAPDSS: DPI: fix LCD3 DSI sourceTomi Valkeinen
At the moment the dpi driver does not handle LCD3 clock source at all. LCD3 channel gets the DSI PLL clock from DSI2 instance. Add support for LCD3's clock source in the dpi driver. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2014-05-09OMAPDSS: remove venc_panel.cTomi Valkeinen
The use of venc_panel.c was removed in 09d2e7cdebd53b7572380a215008b334ff6321a5 (OMAPDSS: VENC: remove code related to old panel model), but the file itself was left behind. Remove the unused file. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2014-05-09omapdss: remove check for simpler port/endpoint bindingArchit Taneja

2014-04-17video: move fbdev to drivers/video/fbdevTomi Valkeinen
The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
