2012-09-07OMAPDSS: Improve fifo management codeTomi Valkeinen1-8/+31
OMAP4+ allows assigning the overlay FIFOs freely, but that is not supported by omapdss yet. This patch takes a step forward by improving the fifo management to be more flexible. dispc.c is changed to keep track of the sizes of each fifo, and also the overlay using each fifo.

2012-09-07Revert "OMAPDSS: APPLY: add fifo merge support funcs"Tomi Valkeinen1-43/+0
This reverts commit fb0119742291b6f30cd97026ee137b2d3d1f4de8. Adding fifo merge feature as an omapdss internal configuration was a mistake. We cannot hide from the users of omapdss the complexities of fifo merge. The previous commit removed fifo merge itself, and this removes the remaining fifo merge support functions.

2012-09-07Revert "OMAPDSS: APPLY: add fifo-merge support"Tomi Valkeinen1-146/+8
This reverts commit 1d71f42b35ed66d90a9a39bc515bb16cfe2d4a46. Adding fifo merge feature as an omapdss internal configuration was a mistake. We cannot hide from the users of omapdss the complexities of fifo merge. This commit removes the fifo merge support, which luckily is easily done as it was handled totally inside apply.c. Note that this is not a 1:1 revert, but some resolving was needed for the dss_ovl_setup_fifo. The plan is to try fifo merge again later when it is more clear how the hardware acts in various situations, and how the omapdrm wants to use fifo merge.

Instead of storing the panel's platform data, we'll "parse" the platform data and store the required information in driver's own data. This way adding device tree data parsing is simple.

Currently vram.c clears the allocated memory automatically using OMAP system DMA. In an effort to reduce OMAP dependencies, we'll do the memory clear with CPU from now on. The previous patch implemented memory clear in the omapfb driver, and this patch removes the now obsolete clear functionality from vram.c.

2012-09-07OMAPDSS: fix use of dssdev->capsTomi Valkeinen4-6/+3
Recent commit dca2b1522ccab28d03fb79f6e70e70ea78033d52 (OMAPDSS: DSI: Maintain copy of operation mode in driver data) broke DSI for video mode displays. The commit changed the way dssdev->caps are initialized, and the result was that every DSI display is initialized with manual-update and tear-elim caps. The code that sets dssdev->caps is not very good, even when fixed. omapdss driver shouldn't be writing dssdev->caps at all. This patch fixes the problem with video mode displays by moving the initialization of dssdev->caps to the panel driver. The same change is done for RFBI.

2012-09-07OMAPDSS: DSI: calculate dsi clockTomi Valkeinen2-0/+132
Currently the way to configure clocks related to DSI (both DSI and DISPC clocks) happens via omapdss platform data. The reason for this is that configuring the DSS clocks is a very complex problem, and it's impossible for the SW to know requirements about things like interference. However, for general cases it should be fine to calculate the dividers for clocks in the SW. The calculated clocks are probably not perfect, but should work. This patch adds support to calculate the dividers when using DSI command mode panels. The panel gives the required DDR clock rate and LP clock rate, and the DSI driver configures itself and DISPC accordingly. This patch is somewhat ugly, though. The code does its job by modifying the platform data where the clock dividers would be if the board file gave them. This is not how it's going to be in the future, but allows us to have quite simple patch and keep the backward compatibility. It also allows the developer to still give the exact dividers from the board file when there's need for that, as long as the panel driver does not override them. There are also other areas for improvement. For example, it would be better if the panel driver could ask for a DSI clock in a certain range, as, at least command mode panels, the panel can work fine with many different clock speeds. While the patch is not perfect, it allows us to remove the hardcoded clock dividers from the board file, making it easier to bring up a new panel and to use device tree from omapdss.

2012-09-07OMAPDSS: HDMI: use vdda_hdmi_dacTomi Valkeinen1-0/+23
The HDMI driver requires vdda_hdmi_dac power for operation, but does not enable it. This has worked because the regulator has been always enabled. But this may not always be the case, as I encountered when implementing HDMI device tree support. This patch changes the HDMI driver to use the vdda_hdmi_dac.

2012-09-07OMAPDSS: HDMI: Move GPIO handling to HDMI driverTomi Valkeinen1-20/+55
We currently manage HDMI GPIOs in the board files via platform_enable/disable calls. This won't work with device tree, and in any case the correct place to manage the GPIOs is in the HDMI driver. This patch moves the handling of the GPIOs to the HDMI driver. The GPIO handling is moved to the common hdmi.c file, and this probably needs to be revisited when adding OMAP5 HDMI support to see if the GPIO handling needs to be moved to IP specific files.
