Here are a bunch of patches that change the DSS2 driver's driver model a bit. This change was triggered by trying to support new hardware, and realizing that the current model just won't work. Currently the omapdss driver is in control of most aspects of the DSS, and omapdss calls necessary functions in display drivers. I made it that way to keep the display drivers simple, and I, naively, thought that it will work because the display panels are using standard bus interfaces and thus will be very similar. I was so wrong =). This patch set moves the control to the display driver. The display driver then calls omapdss functions to perform whatever deed is needed at that time. This will make display drivers slightly more complex, but it will be easier to control the hardware properly with strange or complex display devices. As a simple example, let's look at the update function. Currently user space app issues OMAPFB_UPDATE_WINDOW ioctl, and omapfb driver then calls update() in corresponding dss device struct, which goes to omapdss. omapdss will configure the update, calling the panel driver if needed. After these patches, omapfb will call update() in the panel driver. The panel driver will then call functions in omapdss to setup the update, start the update, and the panel driver will eventually get a callback informing that the update is done. These patches are still under work, but my basic tests on 3430SDP board seems to work ok.
