* drm: omapdrm: displays: Get encoder source at connect timeLaurent Pinchart2018-03-011-44/+22
| | | | | | | | | | | | | | | | The encoder drivers need a handle to the source they are connected to in order to control the source. All drivers get that handle at probe time, resulting in probe deferral when the source hasn't been probed yet. However they don't need the handle until their connect handler is called. Move retrieval of the source handle to the connect handler to avoid probe deferrals.

| | | | | | | | | No encoder is instantiated through platform data anymore, there is no need to check for OF node presence.

* drm: omapdrm: Remove filename from header and fix copyright tagAndrew F. Davis2017-12-191-1/+1
| | | | | | | | | | Having the filename in the header serves little purpose and is often wrong after renames as it is here in several places, just drop it from all omapdrm files. While we are here unify the copyright tags to the TI recommended style. Signed-off-by: Andrew F. Davis <afd@ti.com>
* omapdrm: omapdss_hdmi_ops: add lost_hotplug opHans Verkuil2017-10-121-1/+5
| | | | | | | | | | | The CEC framework needs to know when the hotplug detect signal disappears, since that means the CEC physical address has to be invalidated (i.e. set to f.f.f.f). Add a lost_hotplug op that is called when the HPD signal goes away. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* omapdrm: encoder-tpd12s015: keep ls_oe_gpio highHans Verkuil2017-10-121-8/+4
| | | | | | | | | | | | | | | For OMAP4 CEC support the CEC pin should always be on. So keep ls_oe_gpio high all the time in order to support CEC. Background: even if the HPD is low it should still be possible to use CEC. Some displays will set the HPD low when they go into standby or when they switch to another input, but CEC is still available and able to wake up/change input for such a display. This is explicitly allowed by the CEC standard. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

* drm/omap: tpd12s015: fix error handlingTomi Valkeinen2016-12-081-4/+9
| | | | | | | | tpd12s015 driver is missing error value handling for gpio initialization, causing 0 to be returned as an error if gpiod_get_* fails. This may cause deferred probing to fail. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* drm/omap: Use consistent name for struct videomodePeter Ujfalusi2016-11-021-10/+10
| | | | | | | | | | Use 'vm' to refer to a struct videomode instead of 'p', 't', 'timings' or something else. The code will be easier to follow if we use consistent names. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
* drm/omap: Replace struct omap_video_timings with videomodePeter Ujfalusi2016-11-021-4/+4
| | | | | | | | | | | | | omap_video_timings can be replaced with the generic videomode in omapdrm and the omap_video_timings can be removed. This patch will replace the omap_video_timings with videomode. With the change we no longer need the functions to convert to/from videomode and drm_display_mode to omap_video_timings, these can be removed as well.

* drm/omap: tpd12s015: CT_CP_HPD as optional gpioManisha Agrawal2016-03-031-1/+1
| | | | | | | | | | | | tpd12s015 HW has LS_OE, CT_CP_HPD and HPD gpios. Out of these gpios, driver only handled LS_OE as optional. The CT_CP_HPD gpio should also be treated as optional gpio as it is just a power saving feature. Some boards hardwire this gpio to be always enable. In this patch, all access to CT_CP_HPD gpio is made optional.

* drm/omap: move omapdss & displays under omapdrmTomi Valkeinen2015-12-291-0/+379
Now that omapfb has its own copy of omapdss and display drivers, we can move omapdss and display drivers which omapdrm uses to omapdrm's directory. We also need to change the main drm Makefile so that omapdrm directory is always entered, because omapdss has a file that can't be built as a module.
