This patch series attempts to address a problem of missing support for DSI
bridge-to-bridge or panel-to-bridge clock frequency negotiation. The problem
has two variants.
First, a DSI->to->x bridge derives its own internal clock from DSI HS clock,
but the DSI HS clock cannot be set to arbitrary
Pass negotiated bridge state, which now optionally contains required DSI bus
clock, into dw_mipi_dsi_get_lane_mbps(). The dw_mipi_dsi_get_lane_mbps() is
a misnomer, it is also responsible for configuration of the bridge PLL and
thus also configuration of the clock the bridge outputs on the DSI
Extend struct drm_bus_cfg with a clock field. This makes it possible for an
upstream bridge (further from scanout engine) to indicate to a downstream
bridge which frequency it expects on a link. This is particularly useful in
case of DSI bridges which derive their own internal clock from the DSI
The TC358767/TC358867/TC9595 are all capable of operating without RefClk
Xtal in DSI-to-DPI mode. In this mode of operation, the chip PLLs are fed
with clock derived from the DSI HS clock.
The SYSPLL is fed from DSI HS clock divided by 2*7 and the resulting clock
must match the allowed RefClk
Add new .atomic_get_input_bus_cfgs callback into struct drm_bridge_funcs {}.
This is an extended version of .atomic_get_input_bus_fmts callback which
only returns list of bus formats supported by a bridge and provides no way
to e.g. limit clock frequency required between neighboring bridges.
The
The bridge clock configuration should happen in atomic_enable
instead of mode_set callback, since that is where the current
state of the bridge is available. Move the clock configuration
into atomic_enable callback.

Pass the entire struct drm_bus_cfg {} to select_bus_fmt_recursive()

The bridge_state now contains clock frequency required by the next bridge.
This information is optional, since very few drivers pass this information
now. In case the required clock frequency is part of bridge state, use it
for the DSI bus clock frequency, otherwise fall back to the old guesswork.
