* drm/i2c: tda998x: allow sharing of the CEC device accessesRussell King2016-11-181-19/+34
| | | | | | | | | | | | | | | | | cec_read() is non-atomic in the presence of other I2C bus transactions to the same device. This presents a problem when we add support for the TDA9950 CEC engine part - both drivers can be trying to access the device. Avoid the inherent problems by switching to i2c_transfer() instead, which allows us to perform more than one bus transaction atomically. As this means we will be using I2C transactions rather than SMBUS, we have to check that the host supports I2C functionality.

* drm/i2c: tda998x: allow interrupt to be sharedRussell King2016-11-181-25/+27
| | | | | | | | | | | | | | Some TDA998x contain several different I2C devices - there is the HDMI encoder, and there is a TDA9950 CEC engine. These two share the same interrupt signal. In order to allow a driver for the CEC engine to work, we need to be able to share the interrupt with the CEC driver, so convert the handler and registration to allow this to happen.

| | | | | | | | | | | Disabling the pre-filter block of the TDA998x saves 40mW and the colour conversion block saves 15mW. As we always disable these two blocks, we can power these sections of the chip down to save 55mW of unnecessary power consumption.

* drm/i2c: tda998x: avoid race when programming audioRussell King2016-11-181-2/+2
| | | | | | | | | | | | | | | | | | Avoid a race between programming audio and an in-progress mode set. A mode set is complex, and disables the ability to send infoframes to the sink, and is disruptive to audio - we have to mute the audio FIFO while doing a mode set. If an attempt is made to start up the audio side, we will undo the audio FIFO mute before the mode set has completed. Move the lock so that we prevent audio interfering with an in-progress mode set.

| | | | | | | | | | | | | | | | | As priv->audio_params can now be changed at run time, we need to be more careful about how we deal with a mode set. We must take the audio lock while checking if there's a valid audio configuration. However, it's slightly worse than that - during mode set, we mute the audio, and it must not be unmuted until we have finished the mode set. It is possible that the audio side may start while a mode set is in progress, so take the audio_mutex lock around the whole mode setting procedure.

| * drm/i2c: tda998x: mali-dp: hdlcd: refactor connector registrationBrian Starkey2016-10-311-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Connectors shouldn't be registered until the rest of the whole device is set up, so that consistent state is presented to userspace. As such, remove the calls to drm_connector_register() and drm_connector_unregister() from tda998x, as these are now handled by drm_dev_(un)register() itself. To work with this change, the mali-dp and hdlcd bind and unbind sequences have to be reordered, to ensure that the componentised encoder/connector is bound before drm_dev_register() registers all connectors. Similarly, the device must be unregistered before the component is unbound. Altogether, this allows other drivers using tda998x to be de-midlayered, and to have less racy initialisation of their components. Splitting this commit into three (one per driver) isn't possible without intermediate breakage, so it is all squashed together here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't want to use the old i2c slave encoder interface anymore. Remove that and make the i2c driver create a drm_bridge entity instead. Converting to bridges helps because the kms drivers don't need to exract encoder slave ops from this driver and use it within their own encoder/connector ops. The driver now creates its own connector when a kms driver attaches itself to the bridge. Therefore, kms drivers don't need to create their own connectors anymore. The old encoder slave ops are now used by the new bridge and connector entities. The of_node member in drm_bridge is accessible only when CONFIG_OF is enabled. The driver anyway only works only when OF is available. Make the driver depend on OF in its Kconfig. Signed-off-by: Archit Taneja <architt@codeaurora.org>

The codec also applies constraints for available sample-rates based on Edid Like Data from the display. The device tree binding document has been updated [1]. Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x: Add support of a DT graph of ports"-patch [2]. There may still be some identical lines left from the original patch and some of the ideas have come from there.

Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.
