This function becomes a lot simpler when having passed both the old and new state to it. Looking at all callers, it seems that old_plane_state is never NULL so the check can be dropped.

There are new iterator macros that annotate whether the new or old state should be used. This is better than using a state that depends on whether it's called before or after swap. For clarity, also rename the variables from $obj_state to (old,new)_$obj_state as well. Changes since v1: - Use old/new_*_state for variable names as much as possible. (pinchartl) - Expand commit message. Changes since v2: - Rebase on top of link training patches. - free -> cleanup (pinchartl) Signed-off-by: NMaarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: NLaurent Pinchart <laurent.pinchart@ideasonboard.com> Link: http://patchwork.freedesktop.org/patch/msgid/aafa0d4d-474d-441f-3685-fa6c042ef37e@linux.intel.comTested-by: NLaurent Pinchart <laurent.pinchart@ideasonboard.com>

The THC63LVDM83D is a transparent LVDS encoder. Unlike dumb LVDS encoders it can be controlled through a few pins (power down, LVDS swing, clock edge selection) and requires power supplies. However, on several boards where the device is used neither the control pins nor the power supply are controllable. To avoid developing a separate device-specific driver add a "thine,thc63lvdm83d" compatible entry to the lvds-encoder driver. This will allow supporting many THC63LVDM83D-based boards easily, while allowing future development of an thc63lvdm83d driver when needed without breaking backward compatibility.

The video processing pipeline on the second output on the GE B850v3: Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output Each bridge has a dedicated flash containing firmware for supporting the custom design. The result is that in this design neither the STDP4028 nor the STDP2690 behave as the stock bridges would. The compatible strings include the suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with the firmware which is specific for the GE B850v3. The driver is powerless to control the video processing pipeline, as the two bridges behaves as a single one. The driver is only needed for telling the host about EDID / HPD, and for giving the host powers to ack interrupts. This driver adds one i2c_device for each bridge, but only one drm_bridge. This design allows the creation of a functional connector that is capable of reading EDID from the STDP2690 while handling interrupts on the STDP4028.

The multiplication ratio for the PLL is required to be even due to the use of a "by 2 pre-scaler". Currently we are likely to end up with an odd multiplier even though there is an equivalent set of parameters with an even multiplier. For example, using the 324MHz bit rate with a reference clock of 24MHz we end up with M = 27, N = 2 whereas the example in the PHY databook gives M = 54, N = 4 for this bit rate and reference clock. By walking down through the available multiplier instead of up we are more likely to hit an even multiplier. With the above example we do now get M = 54, N = 4 as given by the databook. While doing this, change the loop limits to encode the actual limits on the divisor, which are: 40MHz >= (pllref / N) >= 5MHz Signed-off-by: NJohn Keeping <john@metanate.com> Reviewed-by: NSean Paul <seanpaul@chromium.org> Signed-off-by: NSean Paul <seanpaul@chromium.org> Link: http://patchwork.freedesktop.org/patch/msgid/20170224125506.21533-18-john@metanate.com
