f7c4a15225 drm/panel: st7701: Add Anbernic RG28XX panel support 
The Anbernic RG28XX is a handheld gaming device with a 2.8 inch 480x640
display. Add support for the display panel.

This panel is driven by a variant of ST7701 driver IC internally,
confirmed by dumping and analyzing its BSP initialization sequence
by using a logic analyzer. It is very similar to the existing
densitron,dmt028vghmcmi-1a panel, but differs in some unknown
register values. Besides, it is connected via SPI, so add a new entry
for the panel.

9a01fb40fd dt-bindings: display: st7701: Add Anbernic RG28XX panel 
The RG28XX panel is a display panel of the Anbernic RG28XX, a handheld
gaming device from Anbernic. It is 2.8 inches in size (diagonally) with
a resolution of 480x640.

This panel is driven by a variant of the ST7701 driver IC internally,
confirmed by dumping and analyzing its BSP initialization sequence
by using a logic analyzer. It is very similar to the existing
densitron,dmt028vghmcmi-1a panel, but differs in some unknown
register values, so add a new entry for the panel to distinguish them.

Additionally, the panel only has an SPI instead of MIPI DSI.
So add and modify for SPI as well.

Although a panel connected via SPI with a D/CX pin theoretically exists,
no such panels have been found for this driver yet. Therefore, disable
the use of the dc-gpios property for all currently known devices.

dpi_hsync_input polarity. Bit 1 is reserved, and should therefore not be

11c742bb5a drm: bridge: anx7625: Use of_property_read_variable_u8_array() 
There's no need to get the length of an DT array property before
parsing the array. of_property_read_variable_u8_array() takes a minimum
and maximum length and returns the actual length (or error code).

This is part of a larger effort to remove callers of of_get_property()
and similar functions. of_get_property() leaks the DT property data
pointer which is a problem for dynamically allocated nodes which may
be freed.

unnecessary calls to clk_disable_unprepare().

Similarly, use devm_clk_get_optional_enabled() helper for cec clock,
which additionally allows to remove the -ENOENT test.

Moreover, the clock related members of struct dw_hdmi are not required
anymore, hence drop them.

If the bridge is attached with the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag set,
this driver won't initialize a connector and hence display mode won't be

validation from drm_connector_helper_funcs::mode_valid() to
drm_bridge_funcs::mode_valid(), because the mode validation is always done
for the bridge.

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.
