68573a5613 drm: renesas: rz-du: rzg2l_du_encoder: Fix max dot clock for DPI 
As per the RZ/G2UL hardware manual Table 33.4 Clock List, the maximum
dot clock for the DPI interface is 83.5 MHz. Add mode_valid callback
to reject modes greater than 83.5 MHz.

cb2e1c2136 drm: remove driver date from struct drm_driver and all drivers 
We stopped using the driver initialized date in commit 7fb8af6798
("drm: deprecate driver date") and (eventually) started returning "0"
for drm_version ioctl instead.

Finish the job, and remove the unused date member from struct
drm_driver, its initialization from drivers, along with the common
DRIVER_DATE macros.

v2: Also update drivers/accel (kernel test robot)

e70140ba0d Get rid of 'remove_new' relic from platform driver struct 
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.

1b5dfd1881 drm: renesas: Move RZ/G2L MIPI DSI driver to rz-du

so it makes sense to move the RZ/G2L MIPI DSI driver there instead of
keeping it in the rcar-du folder. This change improves the organization
and modularity of the driver configuration by grouping related settings together.
