The Rockchip DSI driver was separate till now, not using the common
bridge driver that was introduced a bit later. So this series migrates
over to use that common bridge driver and then also adds support for
dual-dsi to both the bridge and Rockchip glue code.
The bridge-migration itself is based on Nickeys earlier v8
work, but adapted to current kernels and with a new split between probe
and bind, so that we do not create and drop the dsi-host on each deferred
bind attempt.
changes in v2:
- rebase against newer drm code (dsi-bridge+rockchip changes)
- add SPDX header to new glue driver
- expect regular interface lanes from panel (like 4) not the double number
Similar to tegra
- keep links to both master and slave
changes in v3:
- don't defer in bridge_attach, instead add ability to check for finalized
panel attachement, for example in bind
- address bridge-conversion comments from Andrzej:
- include ordering
- moved hwaccess from mode_set to enable callback
- move pllref_clk enablement to bind (needed by bridge mode_set->lane_mbps)
- limited slave settings to dw_mipi_dsi_set_slave
- address dual-dsi comments from Philippe:
- remove unneeded separate variables
- remove unneeded second slave settings
- disable slave before master
- lane-sum calculation comments
changes in v4:
- rebase against some legacy rockchip-dsi changes
- add dsi-component only after panel has attached to dsi host
This solves quite some concurrency problems that happen when trying
to determine dsi-panel availability
Unchanged from review comments:
- kept dw_mipi_dsi_bind, as the dsi->bridge member is only part of the
bridge drivers struct, so not accessible from glue drivers
- kept helper to find second host, as I think it's pretty near to
Archit's description
- kept dual-dsi handling that mimicks tegra
