2016-03-04drm/atomic: Clean up update_output_state.Maarten Lankhorst
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.

2016-02-26drm/fsl-dcu: fix register initializationStefan Agner
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>
2016-02-26drm/fsl-dcu: use mode flags for hsync/vsync polarityStefan Agner
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: Thierry Reding <treding@nvidia.com> Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-02-26drm/fsl-dcu: fix alpha blendingStefan Agner
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: Stefan Agner <stefan@agner.ch>
2016-02-26drm/fsl-dcu: mask all interrupts on initializationStefan Agner
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 <stefan@agner.ch>
2016-02-26drm/fsl-dcu: handle initialization errors properlyStefan Agner
If initialization fails (e.g. due to missing panel node or deferred probe) make sure to roll-back all operations and return the error code. Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-02-26drm/fsl-dcu: avoid memory leak on errorsStefan Agner
Improve error handling during CRTC initialization. Especially avoid memory leaks in the primary plane initialization error path. Signed-off-by: Stefan Agner <stefan@agner.ch>
2016-02-26drm/fsl-dcu: remove regmap return value checksStefan Agner
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 <stefan@agner.ch>
2016-02-26drm/fsl-dcu: specify volatile registersStefan Agner
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: Stefan Agner <stefan@agner.ch>

2016-02-23drm: rcar-du: Output the DISP signal on the ODDF pinLaurent Pinchart
The ODDF signal, output by default on the ODDF pin, isn't used on any board supported in the kernel. As the Gen3 Salvator-X board uses the ODDF pin as a DISP signal, hardcode that configuration in the driver. Use of the ODDF signal will be implemented later through proper DT-based configuration of the DU pins. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2016-02-23drm: rcar-du: Output the DISP signal on the DISP pinLaurent Pinchart

2016-02-23drm: rcar-du: Expose the VSP1 compositor through KMS planesLaurent Pinchart
On R-Car Gen3 SoCs the DU lost its ability to access memory directly and needs to work in conjunction with the VSP to do so. This commit handles the VSP internally to hide it from the user. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2016-02-20drm: rcar-du: Move plane allocator to rcar_du_plane.cLaurent Pinchart

2016-02-20drm: rcar-du: Restart the DU group when a plane source changesLaurent Pinchart
Plane sources are configured by the VSPS bit in the PnDDCR4 register. Although the datasheet states that the bit is updated during vertical blanking, it seems that updates only occur when the DU group is held in reset through the DSYSR.DRES bit. Restart the group if the source changes. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

2016-02-20drm: rcar-du: Add VSP1 support to the planes allocatorLaurent Pinchart
The R8A7790 DU can source frames directly from the VSP1 devices VSPD0 and VSPD1. VSPD0 feeds DU0/1 plane 0, and VSPD1 feeds either DU2 plane 0 or DU0/1 plane 1. Allocate the correct fixed plane when sourcing frames from VSPD0 or VSPD1, and allocate planes in reverse index order otherwise to ensure maximum availability of planes 0 and 1.

2016-02-20drm: rcar-du: Don't update planes on disabled CRTCsLaurent Pinchart
A disabled CRTC can't display planes, the driver shouldn't try to configure it when updating planes. The DRM core will store the plane state for us, and the plane will be configured appropriately the next time the CRTC is enabled. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2016-02-20drm: rcar-du: Remove local CRTC enabled stateLaurent Pinchart
The atomic framework guarantees that the CRTC enable and disable functions will only be called when needed, there's no need to duplicate the CRTC state check. By replacing the local CRTC enabled state check at resume time with the CRTC active state we can remove the local CRTC enabled state altogether.

2016-02-20drm: rcar-du: Perform initialization/cleanup at probe/remove timeLaurent Pinchart
The drm driver .load() operation is prone to race conditions as it initializes the driver after registering the device nodes. Its usage is deprecated, inline it in the probe function and call drm_dev_alloc() and drm_dev_register() explicitly. For consistency inline the .unload() handler in the remove function as well.
