2018-11-09drm/vc4: Prefer PPF over TPZ when dst >= 2/3 srcBoris Brezillon1-4/+4

2018-11-09drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONEBoris Brezillon1-5/+7
For the YUV conversion to work properly, ->x_scaling[1] should never be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE into VC4_SCALING_PPF when that happens. The old ->x_scaling[0] adjustment is dropped as I couldn't find any mention to this constraint in the spec and it's proven to be unnecessary (I tested various multi-planar YUV formats with scaling disabled, and all of them worked fine without this adjustment).

Instead of retrieving the connector from the panel, get it from the encoder with the dedicated helper.

However, judging by the code, PHY is very similar to older Synopsys HDMI PHY described in i.MX6 documentation. Most registers seem to be the same. According to i.MX6 documentation, mpll settings are based on pixel clock and are not specific to each SoC.

Since DW HDMI bridge platform data has different fields for custom and Sysnopsys PHY, function sun8i_hdmi_phy_get_ops() is replaced with sun8i_hdmi_phy_set_ops().
