drm/imx: parallel-display: detach bridge or panel on unbind

2016-08-29T14:30:48+00:00

Don't leave any bridge or panel attached to a stale driver instance when unbinding, to allow reattachment on a rebind. Signed-off-by: Philipp Zabel

drm/imx: don't destroy mode objects manually on driver unbind

2016-08-29T10:45:05+00:00

Instead let drm_mode_config_cleanup() do the work when taking down the master device. This requires all cleanup functions to be properly hooked up to the mode object .destroy callback. Signed-off-by: Lucas Stach Signed-off-by: Philipp Zabel

drm/imx: convey the pixelclk-active and de-active flags from DT to the ipu-di driver

2016-08-08T09:44:20+00:00

The 'de-active' and 'pixelclk-active' DT properties are evaluated by of_parse_display_timing() called from of_get_drm_display_mode(), but later lost in the conversion from videomode.flags to drm_display_mode.flags. Enhance of_get_drm_display_mode() to also return the bus flags in a separate variable, so that they can be passed on to the ipu-di driver. Signed-off-by: Lothar Waßmann Signed-off-by: Philipp Zabel

drm/imx: parallel-display: add bridge support

2016-07-14T09:18:46+00:00

Add support for bridge chips connected externally to the i.MX DISP0/DISP1 DPI interfaces. Signed-off-by: Philipp Zabel

drm/imx: parallel-display: check return code from of_get_drm_display_mode()

2016-07-12T16:26:06+00:00

of_get_drm_display_mode() may fail. Check its return code and bail out on error. Signed-off-by: Lothar Waßmann Signed-off-by: Philipp Zabel

drm/imx: turn remaining container_of macros into inline functions

2016-07-12T16:24:29+00:00

This allows the compiler to do type checking. Signed-off-by: Philipp Zabel

drm/imx: store internal bus configuration in crtc state

2016-07-12T16:24:28+00:00

The internal bus configuration is imx-drm specific crtc state. Store it in imx_crtc_state and let the encoder atomic_check callbacks determine bus_flags, bus_format and the sync pins, possibly taking into account the mode and the connector display info. The custom imx_drm_encoder structure can be replaced again with drm_encoder. Signed-off-by: Philipp Zabel

drm/imx: remove empty mode_set encoder callbacks

2016-07-12T16:24:27+00:00

With atomic modeset support, these callbacks are optional. Signed-off-by: Philipp Zabel

drm/imx: atomic phase 3 step 2: Legacy callback fixups

2016-07-12T16:24:12+00:00

Now that we can use atomic configurations, all the legacy callbacks of CRTCs, encoders and connectors can be switched to the atomic version. For the imx-ldb driver, there is a clock parent setting mismatch bewteen ->enable and ->disable after the switch, so a fixup is added. For the imx-tve driver, since the encoder's callback ->dpms is replaced by ->disable, we need to move the setting for the IPU_CLK_EN bit(in register TVE_COM_CONF_REG) from ->enable/->disable to ->mode_set, otherwise, the relevant CRTC cannot be disabled correctly with a warning on DC stop timeout.

drm/imx: Remove encoders' ->prepare callbacks

2016-07-12T16:23:58+00:00

The main task of imx encoders' ->prepare callbacks is to set bus_format, bus_flags, di_vsync_pin and di_hsync_pin. We may create a structure named imx_encoder to cache them. The atomic encoder callback ->disable may replace ->prepare later, so let's remove ->prepare. Signed-off-by: Liu Ying Acked-by: Daniel Vetter Signed-off-by: Philipp Zabel
