a5d024541e drm/rockchip: dw_hdmi: Fix reading EDID when using a forced mode 
EDID cannot be read on RK3328 until after read_hpd has been called and
correct io voltage has been configured based on connection status.

When a forced mode is used, e.g. video=1920x1080@60e, the connector
detect ops, that in turn normally calls the read_hpd, never gets called.

This result in reading EDID to fail in connector get_modes ops.

Call dw_hdmi_rk3328_read_hpd at end of dw_hdmi_rk3328_setup_hpd to
correct io voltage and allow reading EDID after setup_hpd.

ee689a9500 drm/rockchip: dw_hdmi: Drop superfluous assignments of mpll_cfg, cur_ctr and phy_config 
The mpll_cfg, cur_ctr and phy_config members in struct dw_hdmi_plat_data
are only used to configure the Synopsys PHYs supported internally by DW
HDMI transmitter driver (gpu/drm/bridge/synopsys/dw-hdmi.c), via
hdmi_phy_configure_dwc_hdmi_3d_tx(), which is further invoked from
dw_hdmi_phy_init().  This is part of the internal
dw_hdmi_synopsys_phy_ops struct, managed within dw_hdmi_detect_phy().

To handle vendor PHYs, DW HDMI driver doesn't make use of the internal
PHY ops and, instead, relies on the glue layer to provide the phy_ops
and phy_name members of struct dw_hdmi_plat_data.

Drop the unnecessary assignments of DW internal PHY related members from
structs rk3228_hdmi_drv_data and rk3328_hdmi_drv_data, since both set
the phy_force_vendor flag and correctly provide the expected vendor PHY
data.

6b44aa559d drm/rockchip: vop: clear DMA stop bit on RK3066 
The RK3066 VOP sets a dma_stop bit when it's done scanning out a frame
and needs the driver to acknowledge that by clearing the bit.

Unless we clear it "between" frames, the RGB output only shows noise
instead of the picture. atomic_flush is the place for it that least
affects other code (doing it on vblank would require converting all
other usages of the reg_lock to spin_(un)lock_irq, which would affect
performance for everyone).

This seems to be a redundant synchronization mechanism that was removed
in later iterations of the VOP hardware block.

Reformat the loop to count forwards instead of backwards.
