drm/imx: Fix memory leak in imx_pd_connector_get_modes

2022-04-20T07:06:43Z

[ Upstream commit bce81feb03a20fca7bbdd1c4af16b4e9d5c0e1d3 ] Avoid leaking the display mode variable if of_get_drm_display_mode fails. Fixes: 76ecd9c9fb24 ("drm/imx: parallel-display: check return code from of_get_drm_display_mode()") Addresses-Coverity-ID: 1443943 ("Resource leak") Signed-off-by: José Expósito Signed-off-by: Philipp Zabel Link: https://lore.kernel.org/r/20220108165230.44610-1-jose.exposito89@gmail.com Signed-off-by: Sasha Levin

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

2016-08-29T14:30:48Z

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

2016-08-29T10:45:05Z

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

2016-08-08T09:44:20Z

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

2016-07-14T09:18:46Z

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()

2016-07-12T16:26:06Z

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

2016-07-12T16:24:29Z

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

drm/imx: store internal bus configuration in crtc state

2016-07-12T16:24:28Z

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

2016-07-12T16:24:27Z

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

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

2016-07-12T16:24:12Z

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.
