drm/rockchip already has support for disabling all displays on suspend
and enabling them on resume.
Disable automatic VT switching on suspend by the pm console tracking
layer.
Tested on veyron, used `echo mem > sys/power/state`
=> verified no VT switch

The function disables the dclk at the beginning, so don't simply return
when an error happens, but instead enable the clock again, so that
enable and disable calls are balanced.
ret_clk is introduced to hold the clk_enable result and not mangle the
original error code.

The HannStar HSD070PWW1 LVDS panel data sheet lists allowed ranges
additionally to the typical values for pixel clock rate (64.3-82 MHz)
and blanking intervals (54-681 clock cycles horizontally, 3-23 lines
vertically).
This patch replaces this panel's display mode with the display timing
information to describe acceptable timings. Since the HSYNC and VSYNC
are unused, the distribution between front porches, back porches, and
sync pulse lengths was chosen at will.

Many panel data sheets, additionally to typical values, list allowed
ranges for timings such as hsync/vsync lengths, porches, and the pixel
clock rate. These can be stored in a struct display_timing, to be used
by an encoder mode_fixup callback to clamp user provided timing values
or to validate workarounds for clock source limitations.
This patch adds a new drm_panel_funcs callback that returns the panel's
available display_timing entries.

Instead of duplicating the code, make use of the newly introduced atomic
state duplicate and destroy helpers. This allows changes to the base
atomic state handling to automatically propagate to the Tegra driver and
thereby prevent breakage resulting from both copies going out of sync.
Signed-off-by: Thierry Reding <treding@nvidia.com>
|

Drivers that subclass CRTC, plane or connector state need to carefully
duplicate the code that the atomic helpers have. This is bound to cause
breakage eventually because it requires auditing all drivers and update
them when code is added to the helpers.
In order to avoid that, implement new helpers that perform the required
steps when copying and destroying state. These new helpers are exported
so that state-subclassing drivers can use them. The default helpers are
implemented using them as well, providing a single location that needs
to be changed when adding to base atomic states.

SMP blocks are configured for specific client IDs (ports).
These client IDs can be different from one chip to another for a
given pipe.
e.g.: DMA0 pipe fetch Y component is connected to:
- port #10 for MDP5 v1.3
- port #4 for MDP5 v1.6
In order to be compatible for upcoming versions of MDP5, the
client ID list is passed through the MDP5 config module rather
than using a list of hard-coded enum values.

DSI and WB interfaces need a more complex pipeline configuration
than the current mdp5_ctl_set_intf().
For example, memory output connections need to be selected for
WB. Interface mode (Video vs. Command modes) also need to be
configured for DSI.
This change takes care of configuring the whole pipeline as far
as operation mode goes. DSI and WB interfaces will be added
later.
