Subject: [PATCH v3 0/2] Add mode_valid hook for sii902x bridge

Currently, there are no check to validate the modes in the bridge.
Add pixel clock check to validate the modes that the bridge can support.

Also add the mode_valid hook in drm_bridge_funcs structure to take care
of the case when the encoder attaches the bridge chain with the
DRM_BRIDGE_ATTACH_NO_CONNECTOR flag in which case, the connector is not
initialized in the bridge's attach call.

Also add this check to the atomic_check call as suggested by Maxime in
v1 patch.

Changelog v2->v3:
- Remove newline that was introduced in [1/2] and later deleted in [2/2]
  in v2

v2 patch:
<https://lore.kernel.org/all/20240524073305.107293-1-j-choudhary@ti.com/>

Changelog v1->v2:
- Add KHZ suffix in the macros to be more clear
- Add the hook for drm_bridge_funcs as well
- Add check in atomic_check dunction call (in a separate patch)

v1 patch:
<https://lore.kernel.org/all/20240408081435.216927-1-j-choudhary@ti.com/>
