error. For TDM mode, McASP is capable to play or receive 32 channels for one

Archit Taneja [Tue, 26 Mar 2013 13:45:19 +0000 (19:15 +0530)]
drm/omap: Fix and improve crtc and overlay manager correlation

The omapdrm driver currently takes a config/module arg to figure out the number
of crtcs it needs to create. We could create as many crtcs as there are overlay
managers in the DSS hardware, but we don't do that because each crtc eats up
one DSS overlay, and that reduces the number of planes we can attach to a single
crtc.

Since the number of crtcs may be lesser than the number of hardware overlay
managers, we need to figure out which overlay managers to use for our crtcs. The
current approach is to use pipe2chan(), which returns a higher numbered manager
for the crtc.

The problem with this approach is that it assumes that the overlay managers we
choose will connect to the encoders the platform's panels are going to use,
this isn't true, an overlay manager connects only to a few outputs/encoders, and
choosing any overlay manager for our crtc might lead to a situation where the
encoder cannot connect to any of the crtcs we have chosen. For example, an
omap5-panda board has just one hdmi output. If num_crtc is set to 1, with the
current approach, pipe2chan will pick up the LCD2 overlay manager, which cannot
connect to the hdmi encoder at all. The only manager that could have connected
to hdmi was the TV overlay manager.

Therefore, there is a need to choose our overlay managers keeping in mind the
panels we have on that platform. The new approach iterates through all the
available panels, creates encoders and connectors for them, and then tries to
get a suitable overlay manager to create a crtc which can connect to the
encoders.

We use the dispc_channel field in omap_dss_output to retrieve the desired
overlay manager's channel number, we then check whether the manager had already
been assigned to a crtc or not. If it was already assigned to a crtc, we assume
that out of all the encoders which intend use this crtc, only one will run at a
time. If the overlay manager wan't assigned to a crtc till then, we create a
new crtc and link it with the overlay manager.

This approach just looks for the best dispc_channel for each encoder. On DSS HW,
some encoders can connect to multiple overlay managers. Since we don't try
looking for alternate overlay managers, there is a greater possibility that 2
or more encoders end up asking for the same crtc, causing only one encoder to
run at a time.

Also, this approach isn't the most optimal one, it can do either good or bad
depending on the sequence in which the panels/outputs are parsed. The optimal
way would be some sort of back tracking approach, where we improve the set of
managers we use as we iterate through the list of panels/encoders. That's
something left for later.

drm/omap: Take a fb reference in omap_plane_update()

When userspace calls SET_PLANE ioctl, drm core takes a reference of the fb and
passes control to the update_plane op defined by the drm driver.

In omapdrm, we have a worker thread which queues framebuffers objects received
from update_plane and displays them at the appropriate time.

It is possible that the framebuffer is destoryed by userspace between the time
of calling the ioctl and apply-worker being scheduled. If this happens, the
apply-worker holds a pointer to a framebuffer which is already destroyed.

Take an extra refernece/unreference of the fb in omap_plane_update() to prevent
this from happening. A reference is taken of the fb passed to update_plane(),
the previous framebuffer (held by plane->fb) is unreferenced. This will prevent
drm from destroying the framebuffer till the time it's unreferenced by the
apply-worker.

This is in addition to the exisitng reference/unreference in update_pin(),

drm/omap: move out of staging

Now that the omapdss interface has been reworked so that omapdrm can use
dispc directly, we have been able to fix the remaining functional kms
issues with omapdrm.  And in the mean time the PM sequencing and many
other of that open issues have been solved.  So I think it makes sense
to finally move omapdrm out of staging.

omapdss: hdmi: Add an i2c adapter node as a possible DT phandle

The hdmi driver supports reading edid either via HDMI IP's ddc in the case
of omap4. We support a bitbanged gpio i2c mode for omap5. For Vayu, the pins
muxed with HDMI IP's ddc are the I2C2 lines, so we provide a mode where we allow
the i2c adapter to be passed as a phandle by DT.

Add a DT node for hdmi similar to that as of omap5-uevm. The difference on Vayu
evm is that it the hdmi ddc lines are the I2C2 line instead of bitbanged gpio
lines. There is a also a PCF level shifter on I2C2 which is used to drive LS_OE
and CT_HPD pins in the TPS level shifter. The HPD gpio is connected directly to
a Vayu GPIO bank.

HACK: omapdss: HDMI hacks for DRA7x

- Vayu evm has a demux which decides whether i2c2 lines go to the hdmi level
shifter(and finally to the panel) or if they are in their normal state(where
i2c2 is connected to many slaves, one of which is a gpio expander to configure
the LS_OE and CT_HPD pins of the level shifter). This demux is controlled by
a mcasp based gpio. There is no mcasp-gpio driver, neither there is a clean
way to represent such a pin in DT. So the bit is toggled as a hack in the
hdmi driver itself.

- On DRA7x, hdmi phy state transition checks are failing even though hdmi phy is
transitioning correctly, ignore the phy transition checks for now.

These need to be cleaned up later.
