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.
The patches can also be found from

Physical DSI bus is protected by a mutex. This patch changed the mutex to
a semaphore, so that we can lock and unlock the bus_lock from different
threads.
This is needed as the update process is started by user space program, and
thus the lock is acquired in that context, but the lock can be released in
different context, a work thread via irq.

Remove performance measurement for auto-update. Auto-update and thus
performance measurement cannot be supported after the driver change where
the control is moved to display drivers.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.

From: Tomi Valkeinen @ 2010-02-08 15:57 UTC (permalink / raw)
To: linux-omap, linux-fbdev; +Cc: Tomi Valkeinen
Move update() and sync() from omap_dss_device to omap_dss_driver.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.

To: linux-omap, linux-fbdev; +Cc: Tomi Valkeinen
Move enable/disable/suspend/resume from omap_dss_device to
omap_dss_driver.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.

From: Tomi Valkeinen @ 2010-02-08 15:57 UTC (permalink / raw)
To: linux-omap, linux-fbdev; +Cc: Tomi Valkeinen
Move set/get_wss() from omap_dss_device to omap_dss_driver.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.

To: linux-omap, linux-fbdev; +Cc: Tomi Valkeinen
Move check/set/get_timings() from omap_dss_device to omap_dss_driver.
This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.
