connector_state->crtc can no longer be unset by accident, so that check can be removed. The other code open-codes drm_atomic_get_existing_crtc_state, so use that. Signed-off-by:

Now that only encoders can be stolen that are part of the state steal_encoder no longer needs to inspect all connectors, just those that are part of the atomic state. Changes since v1: - Change return value to void, can no longer fail. Signed-off-by:

The current check doesn't handle the case where we don't steal an encoder, but keep it on the current connector. If we repurpose disable_conflicting_encoders to do the checking, we just have to reject the ones that conflict. Changes since v1: - Return early with empty encoder_mask, drm_for_each_connector requires connection_mutex held. Changes since v2: - Add comments for the loops. Signed-off-by:

Instead of failing with -EINVAL when conflicting encoders are found, the legacy set_config will disable other connectors when encoders conflict. With the previous commit this becomes a lot easier to implement. set_config only adds connectors to the state that are modified, and because of the previous commit that calls add_affected_connectors only on set->crtc it means any connector not part of the modeset can be stolen from. We disable the connector in that case, and possibly the crtc if required. Atomic modeset itself still doesn't allow encoder stealing, the results would be too unpredictable. Signed-off-by:

There's no need to have a separate function to get the crtc which is stolen, this can already be found when actually stealing the encoder. drm_for_each_connector already checks for connection_mutex, so use that macro now. Changes since v1: - Do not check for NULL crtc in connector_state, this may happen when a crtc is disabled and its encoder stolen. - Because of this, use connector->state->crtc instead of conn_state->crtc.

Minor cleanup, connector and connector_state are always non-NULL here. Signed-off-by:
-
Maarten Lankhorst authored
With the addition of crtc_state->connector_mask other connectors from different crtc's aren't needed any more to determine if a crtc has connectors, so only call add_affected_connectors on the target crtc. This allows a cleanup to first remove all current connectors, then add all set->connectors to the target crtc. Signed-off-by:

The layer enumeration start with 0 (0-15 for LS1021a and 0-63 for Vybrid) whereas the register enumeration start from 1 (1-10 for LS1021a and 1-9 for Vybrid). The loop started off from 0 for both iterations and initialized the number of layers inclusive, which is one layer too many. All extensively written registers seem to be unassigned, it seems that the write to those registers did not do any harm in practice. Signed-off-by:Stefan Agner <stefan@agner.ch>

The current default configuration is as follows: - Invert VSYNC signal (active LOW) - Invert HSYNC signal (active LOW) The mode flags allow to specify the required polarity per mode. Furthermore, none of the current driver settings is actually a standard polarity. This patch applies the current driver default polarities as explicit flags to the display which has been introduced with the driver (NEC WQVGA "nec,nl4827hc19-05b"). The driver now also parses the flags field and applies the configuration accordingly, by using the following values as standard polarities: (e.g. when no flags are specified): - VSYNC signal not inverted (active HIGH) - HSYNC signal not inverted (active HIGH) Acked-by:

Fix alpha blending by enabling alpha blending for the whole frame if a color mode with alpha channel is selected (DRM_FORMAT_ARGB*). Also support color modes without alpha channel (DRM_FORMAT_XRGB*) by just not enabling alpha blending on layer level. Signed-off-by: -

The state of the interrupt mask register on initialization is unknown, e.g. U-Boot could already used the DCU. So depending on the boot loader, the outcome of the interrupt mask register could be different. A defined state is much more preferable. Also, there is no value in keeping interrupts enabled which we don't need. Therefor, mask all interrupts on initialization. Signed-off-by: -

Stefan Agner authored
It is not common to do regmap return value checks, especially not for memory mapped device. We can rule out most error returns since the conditions are static and we know they are ok (e.g. offset aligned to register stride). Also without proper error handling they are not really valuable for the user. Hence remove most of them. The check in the interrupt handler is worth keeping since a volatile register won't be readable in case register caching is still enabled. Signed-off-by: -
Stefan Agner authored
Since we are using cached registers, we need to specify volatile registers explicitly to avoid reading their value from the cache. This allows to read the correct interrupt status in fsl_dcu_drm_irq and clear the asserted bits only. Signed-off-by: -
