2018-10-15drm/v3d: Add a little debugfs entry for measuring the core clock.Eric Anholt2-0/+65
This adds just enough performance counter support to measure the clock.

2018-10-11drm: Do not call drm_dp_cec_set_edid() while registering DP connectorsJosé Roberto de Souza1-2/+0
drm_dp_cec_register_connector() is called when registering each DP connector in DRM, while sounds a good idea register CEC adapters as earlier as possible, it causes some driver initialization delay trying to do DPCD transactions in disconnected connectors. This change will cause no regressions as drm_dp_cec_set_edid() will still be called in further detection of connected connectors with a valid edid parameter. This change reduced the module load of i915 by average 0.5sec in a machine with just one DP port disconnected while reducing more than 3sec in a machine with 4 DP ports disconnected.

With armada the last bigger driver that realistically needed these to convert from legacy kms to atomic is converted. These helpers have been broken more often than not the past 2 years, and as this little patch series shows, tricked a bunch of people into using the wrong helpers for their functions.

One example are the Rockchip rk3228 and rk3328 socs that use a separate vendor-type phy from Innosilicon but still report the HDMI20_TX type. So allow the glue driver to force the vendor-phy for these cases. In the future it may be necessary to allow forcing other types, but for now we'll keep it simply to the case actually seen in the wild. changes in v3: - only allow forcing vendor type, as suggested by Laurent Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Robin Murphy <robin.murphy@arm.com> Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> Reviewed-by: Zheng Yang <zhengyang@rock-chips.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180912124740.20343-2-heiko@sntech.de Link: https://patchwork.freedesktop.org/patch/msgid/20180912124740.20343-3-heiko@sntech.de
2018-09-27drm: stm: implement get_scanout_position functionBenjamin Gaignard3-0/+52
Hardware allow to read the position in scanout buffer so we can use this information to make wait of vblank more accurate. Active area bounds (start, end, total height) have already been computed and written in ltdc registers, read them and get the current line position to compute vpos value.

2018-09-27drm/panel: Add support for Olimex LCD-OLinuXino panelStefan Mavrodiev3-0/+343
This patch adds Olimex Ltd. LCD-OLinuXino bridge panel driver. The panel is used with different LCDs (currently from 480x272 to 1280x800). A small EEPROM chip is used for identification, which holds some factory data and timing requirements.

2018-09-27drm/panel: simple: Add support for Banana Pi 7" S070WV20-CT16 panelChen-Yu Tsai1-0/+25
This panel is marketed as Banana Pi 7" LCD display. On the back is a sticker denoting the model name S070WV20-CT16. This is a 7" 800x480 panel connected through a 24-bit RGB interface. However the panel only does 262k colors. Depending on the variant, the PCB attached to the panel module either supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel itself.

Because of the too generic DMI strings this entry is also doing bios-date matching, so the gpd_win2 data struct may very well need to be updated with some extra bios-dates in the future.
