2017-10-12drm/vblank: Fix flip event vblank countVille Syrjälä
On machines where the vblank interrupt fires some time after the start of vblank (or we just manage to race with the vblank interrupt handler) we will currently stuff a stale vblank counter value into the flip event, and thus we'll prematurely complete the flip. Switch over to drm_crtc_accurate_vblank_count() to make sure we have an up to date counter value, crucially also remember to add the +1 so that the delayed vblank interrupt won't complete the flip prematurely.

The HDMI controller found in the A31 SoCs is slightly different from the one already supported, which is found in the A10s: - Need different initial values for the PLL related registers - Different behavior of the DDC and TMDS clocks - Different register layout for the DDC portion - Separate DDC parent clock This patch adds support for it.

2017-10-11drm/sun4i: hdmi: Add support for controller hardware variantsChen-Yu Tsai
The HDMI controller found in earlier Allwinner SoCs have slight differences between the A10, A10s, and the A31: - Need different initial values for the PLL related registers - Different behavior of the DDC and TMDS clocks - Different register layout for the DDC portion - Separate DDC parent clock on the A31 - Explicit reset control For the A31, the HDMI TMDS clock has a different value offset for the divider. The HDMI DDC block is different from the one in the other SoCs. As far as the DDC clock goes, it has no pre-divider, as it is clocked from a slower parent clock, not the TMDS clock. The divider offset from the register value is different. And the clock control register is at a different offset. A new variant data structure is created to store pointers to the above functions, structures, and the different initial values. Another flag notates whether there is a separate DDC parent clock. If not, the TMDS clock is passed to the DDC clock create function, as before. Regmap fields are used to deal with the different register layout of the DDC block.

2017-10-11drm/sun4i: hdmi: create a regmap for later useChen-Yu Tsai
The HDMI driver is written with readl/writel I/O to the registers. However, to support the A31 variant, which has a different layout for the DDC registers, it was recommended to use regfields to have a cleaner implementation. To use regfields, we need to create an underlying regmap. This patch only adds the regmap. It does not convert the existing driver accesses to use regmap.

2017-10-11drm/sun4i: hdmi: Disable clks in bind function error path and unbind functionChen-Yu Tsai
The HDMI driver enables the bus and mod clocks in the bind function, but does not disable them if it then bails our due to any errors. Neither does it disable the clocks in the unbind function. Fix this by adding a proper error path to the bind function, and clk_disable_unprepare calls to the unbind function. Also rename the err_cleanup_connector label to err_cleanup_encoder, since it is the encoder that gets cleaned up.

2017-10-11drm/sun4i: tcon: Add variant callback for TCON output muxingChen-Yu Tsai
Different SoCs have different muxing options and values for the TCON outputs. Instead of stuffing every possibility in sun4i_tcon_set_mux(), add a callback pointer to sun4i_tcon_quirks that each TCON variant can use to provide muxing support. The current muxing options in sun4i_tcon_set_mux() for sun5i-a13 are moved to a new sun5i-specific callback function. Since the new callback replaces what the .has_unknown_mux field in tcon quirks did in the past, the field is removed.
