94bedc45ac drm/rockchip: add ability to handle external dphys in mipi-dsi
While the common case is that the dsi controller uses an internal dphy,
accessed through the phy registers inside the dsi controller, there is
also the possibility to use a separate dphy from a different vendor.

One such case is the Rockchip px30 that uses a Innosilicon Mipi dphy,
so add the support for handling such a constellation, including the pll
also getting generated inside that external phy.

25ed8aeb9c drm/bridge/synopsys: dsi: driver-specific configuration of phy timings
The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.

To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.

Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.

changes in v5:
- rebase on 5.5-rc1
- merge into px30 dsi series to prevent ordering conflicts

changes in v4:
- rebase to make it directly fit on top of drm-misc-next after all

changes in v3:
- check existence of phy_ops->get_timing in __dw_mipi_dsi_probe()
- emit actual error when get_timing() call fails
- add tags from Philippe and Yannick

changes in v2:
- add driver-specific handling, don't force all bridge users to use
  the same timings, as suggested by Philippe

f4563f3cec drm/rockchip: use DRM_DEV_ERROR for log output
Replace the use of the dev_err macro with the DRM_DEV_ERROR
DRM helper macro. rockchip driver uses almost exclusively DRM_* logging
(aside from 2 dev_* instances, one of which is converted in this patch),
so this makes things more consistent.

c2156ccd96 drm/rockchip: drop use of drmP.h
Drop use of the deprecated drmP.h header file.

While touching the list of include files move the
blocks so they follow the common pattern:

\#include <linux/*>

\#include <video/*>

\#include <drm/*>

\#include ""

Within each block sort the include files.
Add the includes needed to fix build after the removal of drmP.h.

63f8f3badf drm: bridge: Constify mode arguments to bridge .mode_set() operation
The mode and ajusted_mode passed to the bridge .mode_set() operation
should never be modified by the bridge (and are not in any of the
existing bridge drivers). Make them const to make this clear.

cf6d100dd2 drm/rockchip: dsi: add dual mipi support
Add the Rockchip-sepcific dual-dsi setup and hook it into the VOP as well.
As described in the general dual-dsi devicetree binding, the panel should
define two input ports and point each of them to one of the used dsi-
controllers, as well as declare one of them as clock-master.
This is used to determine the dual-dsi state and get access to both
controller instances.

v6:
  handle master+slave component in dsi-attach
v5:
  use driver-internal mechanism to find dual dsi slave
v4:
  add component directly in probe when adding empty dsi slave controller
