There's no need to print an error message on probe deferral, that's a
normal situation. Probe deferral debugging can be performed by enabling
the related debug messages in the drivers core.

The omap_gem_resume() function is internal to the driver. Pass it a
drm_device pointer that the caller already has instead of looking it up
from device data.

There's no need for the omapdss-base code to be part of a separate
module. Merge it with the omapdss module. This allows removing the
exports for internal symbols.

As this series merges omapdrm and omapdss I think it would make sense to
support DSS[2-5] and DSS6 in the same module (probably with a Kconfig option
to select which variant(s) to support).

When merging the omapdrm and omapdss drivers the omapdrm virtual
platform device will disappear, and the omapdss platform device will be
used for DMA memory allocation. To prepare for that, set the DMA
coherent mask for the device.

The dpi_data structure port_initialized field is used to check in the
cleanup path whether the DPI has been initialized. This can be performed
through the associated device_node data field instead. Remove the
port_initialized field.

The venc_probe_of() function has an error cleanup path that returns
success instead of an error code. Fix it.

The number of function declarations in the omap_drv.h degrades
readability. To fix it, create new header files for each part of the
driver and move the related functions.

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The kernel favours 'unsigned int' over plain 'unsigned'. Replace all
occurences of the latter by the former. This avoid lots of checkpatch
complaints in patches that touch lines where a plain 'unsigned' is used.

When merging the omapdrm and omapdss drivers there will be not omapdrm
platform device anymore, and thus no associated probe and remove
functions. To prepare for that, split all the initialization code from
the probe function to make it usable without a platform device.
Similarly, split the cleanup code from the remove function.

The tvc_of_match variable is never referenced before its definition.
Remove the forward declaration.

The connector drivers need a handle to the source they are connected to
in order to control the source.
All drivers get that handle at probe time, resulting in probe deferral
when the source hasn't been probed yet. However they don't need the
handle until their connect handler is called.
Move retrieval of the source handle to the connect handler to avoid
probe deferrals.

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The connector drivers need a handle to the source they are connected to
in order to control the source.
All drivers get that handle at probe time, resulting in probe deferral
when the source hasn't been probed yet. However they don't need the
handle until their connect handler is called.
Move retrieval of the source handle to the connect handler to avoid
probe deferrals.

To: dri-devel; +Cc: Tomi Valkeinen
The encoder drivers need a handle to the source they are connected to in
order to control the source.
All drivers get that handle at probe time, resulting in probe deferral
when the source hasn't been probed yet. However they don't need the
handle until their connect handler is called.
Move retrieval of the source handle to the connect handler to avoid
probe deferrals.

To: dri-devel; +Cc: Tomi Valkeinen
The split between the omapdss and omapdrm driver is historic and was due
to other userspace APIs (FBDEV and V4L2) being supported in addition to
DRM/KMS. Now that the drivers only supports the DRM/KMS API, there is no
need to keep them separate anymore.
Merge the two drivers and remove the now unneeded omapdrm virtual
platform device.

To simplify implementation of debugfs seq_file show handlers, the driver
passes the pointer to the show function through the debugfs_create_file
data pointer. This prevents using the pointer to pass driver private
data to the show handler, and requires all handlers to use global
variables to access private data.
To prepare for the removal of global private data in the driver, rework
the debugfs infrastructure to allow passing a private data pointer to
show handlers.
The price to pay is explicit removal of debugfs files to free the
internally allocated memory. This is desirable anyway as debugfs entries
should be removed when a component driver is unbound, otherwise crashes
will occur due to access to freed memory when the components will be
dynamically allocated instead of stored in global variables.

Indeed, it's a leftover from a previous version where I was still exposing
struct dentry. I'll remove it in v2.

To prepare for the removal of the global variable storing DSS private
data, pass its pointer to the dss_runtime_{get,put}() functions.
As this requires getting hold of the DSS private structure in the
callers, we expose the structure through an opaque pointer that can be
retrieved through a new dss_device_get() function. The function
currently returns a pointer to the global data structure, and will later
be updated to get the pointer from device driver data when the DSS
private structure will be allocated dynamically.

This removes the need to access the global DSS private data in those
functions (both for the current accesses and the future ones that will
be introduced when allocating the DSS device dynamically).

fine.

This removes the need to access the global DSS private data in those
functions (both for the current accesses and the future ones that will
be introduced when allocating the DSS device dynamically).

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The DSS private data structure is currently stored as a global variable.
While no platform with multiple DSS devices currently exists nor is
planned, this doesn't comply with the kernel device model and should
thus be fixed.
As a first step to the fix, allocate the DSS private data structure
dynamically for each DSS instance. The pointer still needs to be stored
in a global variable as many functions exposed outside of the dss module
don't have access to the DSS private data structure. This will be fixed
in subsequent steps.

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The omap_hdmi private data structure is currently stored as a global
variable. While no platform with multiple HDMI4 encoders currently
exists nor is planned, this doesn't comply with the kernel device model
and should thus be fixed.

To: dri-devel; +Cc: Tomi Valkeinen
The omap_hdmi private data structure is currently stored as a global
variable. While no platform with multiple HDMI5 encoders currently
exists nor is planned, this doesn't comply with the kernel device model
and should thus be fixed.

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The venc private data structure is currently stored as a global
variable. While no platform with multiple VENC encoders currently exists
nor is planned, this doesn't comply with the kernel device model and
should thus be fixed.

variable. While no platform with multiple SDI encoders currently exists
nor is planned, this doesn't comply with the kernel device model and
should thus be fixed.

The wait_for_bit_change() function returns the value of the bit it
polls. This requires the caller to compare the return value to the
expected bit value. As all the existing callers need is to check whether
the bit has reached the expected value, it's easier to return a boolean
status from the function.

Internal dsi functions take a pointer to the DSI platform_device and
then cast it to a dsi_data pointer. That's pointless as the caller
already has the dsi_data pointer. Pass it directly instead of the

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
The dsi_get_dsidrv_data() and dsi_get_dsidev_from_dssdev() inline
functions convert a struct omap_dss_device pointer to the corresponding
struct platform_device, and a struct platform_device pointer to the
corresponding struct dsi_data. They are nearly always called together
without any use of the intermediate platform_device, so combine them
into a single function.
In the three locations where only dsi_get_dsidrv_data() is used, call
dev_get_drvdata() directly.

The dsi_bind() function receives a pointer to a struct device that it
casts to a struct platform_device, only to use the platform device's dev
field through the code. Use the dev pointer directly.
While at it rename the struct platform_device pointer dsidev to pdev to
make it more explicit.

The dsi_data structure stores a pointer to a struct platform_device. The
driver only uses the dev member of the platform device structure. Store
the struct device pointer instead and use it directly.

The dsi_display_init_dispc() and dsi_display_uninit_dispc() functions
take a channel argument that is reduntant as it is always identical to
the dsi->output.dispc_channel. Remove the argument and use the field
directly in the functions to avoid misuse.

The dss_mgr_*() functions take a channel argument to identify the
channel they operate on. This prevents the functions from accessing
driver data structures without resorting to global variables. In an
effort to remove global variables, pass the omap_dss_device pointer
associated with the channel instead. This will be used to look up the
omap_drm_private data structure to pass to the dss_mgr_ops.

The omap_dss_register_driver(), omap_dss_unregister_driver() and
dispc_enable_gamma_table() functions don't exist anymore, remove their
prototypes.

The dss_mgr_ops operations implemented by the omapdrm side have to look
up the omap_crtc objects from global variables as they are only passed a
channel number. In order to remove global variables pass the
omap_drm_private pointer to the dss_mgr_ops. This requires storing a
pointer to the dss_device in the omap_dss_device structure to allow
looking up the omap_drm_private in the dss_mgr_*() functions.

To: dri-devel; +Cc: Tomi Valkeinen
This removes the need to access the global DISPC private data in those
functions (both for the current accesses and the future ones that will
be introduced when allocating the DISPC private data dynamically).
In order to allow the omapdrm side to call the dispc_ops with a DISPC
pointer, we also introduce a new function dss_get_dispc() to retrieve
the DISPC corresponding to the DSS.

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
This removes the need to access the global DISPC private data in those
functions (both for the current accesses and the future ones that will
be introduced when allocating the DISPC private data dynamically).

I've split the changes in two patches to try and keep them reviewable, given
the amount of lines changed, but I'm fine merging them together too.

The dispc private data structure is currently stored as a global
variable. While no platform with multiple DISPC currently exists
nor is planned, this doesn't comply with the kernel device model and
should thus be fixed.

From: Laurent Pinchart @ 2017-10-13 14:59 UTC (permalink / raw)
To: dri-devel; +Cc: Tomi Valkeinen
As part of an effort to remove the usage of global variables in the
driver, store the debugfs root directory in the dss_device structure
instead of a global variable.

And great review ! :-) Thank you.
There will be more coming, probably another cleanup round before I start
moving the encoder, connector and panel drivers to drm_bridge and drm_panel.

If I disable HDMI audio, the spam goes away, and I just get:
[ 14.783558] dmm 4e000000.dmm: initialized all PAT entries
[ 14.805775] DSS: OMAP DSS rev 6.1

[ 14.833482] omapdss_dss 58000000.dss: master bind failed: -517
When I remove modules, something is left enabled as I get:
[ 99.623954] platform 58000000.dss: enabled after unload, idling
If, after loading omapdrm as above, I also load encoder/panel drivers, I get a picture after a spam of "omapdss_dss 58000000.dss: master bind failed: -517" and "alloc_contig_range: [fd874, fd875) PFNs busy" messages.
But then, I can't unload any modules as they are all in use.

I initially thought this would disappear after fixing the other issues, but it
seems to be a problem of its own, which I have thus investigated. I had to
trace through the runtime PM code to understand what was going on, which
wasn't a pleasant experience, but I managed to find the root cause and to
create a fix.
The culprit is initialization of runtime PM in the DSS component master bind
handler coupled with probe deferral from within that handler.
The bind handler performs the following sequence of PM operations:
pm_runtime_enable(dev);
pm_runtime_get_sync(dev);
... (access the hardware to read the device revision) ...
pm_runtime_put_sync(dev);
If a failure occurs at this point, the error path calls pm_runtime_disable()
to balance the pm_runtime_enable() call.
Now it should be noted that the bind handler is called when one of the
component registers itself, which happens in the component's probe handler.
Furthermore, as the components are children of the DSS, the device core calls
pm_runtime_get_sync() on the DSS platform device before calling the
component's probe handler. This increases the DSS power usage count but
doesn't runtime resume the device, as runtime PM is disabled at that point.
The bind handler is thus called with runtime PM disabled, with the device
runtime suspended, but with the power usage count larger than 0. The
pm_runtime_get_sync() call will thus further increase the power usage count
and runtime resume the device. The pm_runtime_put_sync() handler will decrease
the power usage count to a non-zero value and will thus not suspend the
device. Finally, the pm_runtime_disable() call will disable runtime PM,
preventing the pm_runtime_put() call in the device core from runtime
suspending the device. The DSS device is thus left powered on.
To fix this, I've created a patch that moves the runtime PM initialization
code (as well as most of the rest of the initialization code) from the bind
handler to the probe handler. I'll post it in v2 of this series.

So how do the loadtime and runtime dependencies go with this series? In
the current mainline, it's kind of clear:
We have omapdss, and the panel and encoder drivers register themselves
to omapdss. So panels and encoders depend on omapdss. On top of that we
have omapdrm which then uses both omapdss and panels. Unloading happens
in reverse order.
With only omapdrm, the panels and encoders must depend on that. But
omapdrm will use the panels, so there's a runtime dependency that way.
Do we need to use sysfs's unbind first to remove some drivers, before
module unloading is possible? Which ones? Does it work?
Tomi

I've picked the following patches from the beginning of the series for
v4.16. I would have picked a few more, but started to get conflicts.
drm: omapdrm: Deconstruct the omap_drv.h header.
drm: omapdrm: venc: Return error code on OF parsing failure
drm: omapdrm: dpi: Remove dpi_data port_initialized field
drm: omapdrm: dss: Make dss_dump_clocks() function static
drm: omapdrm: dss: Set the DMA coherent mask
drm: omapdrm: Remove unused omap_dss_find_device() function
drm: omapdrm: Pass drm_device to omap_gem_resume()
drm: omapdrm: dpi: Don't treat GPIO probe deferral as an error
