LF-9952 clocksource: imx-tpm: Wait for CnV write to take effect
The value write into the TPM CnV can only be updated into the HW when
CNT increase. Additional writes to the CnV write buffer are ignored until
the register has been updated. So we need to check if the CnV has been
updated before continue. Wait for 1 CNT cycle in worst case.
Additionally, current return check is not correct, if a max_delta need
be set, it will return -ETIME wrongly due to the int type cast,
so refine the check logic to fix it.

…O_CONNECTOR case If DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is set when attaching the bridge, this bridge driver won't create a DRM connector but instead relying on other drivers to do that, i.e., a bridge connector is created by a DRM driver. In that case, it6263_get_edid() should use the connector parameter of it6263_bridge_edid_read() to get EDID instead of the connector created by this driver for the !DRM_BRIDGE_ATTACH_NO_CONNECTOR case and cached in the main struct it6263, since the latter one is not initialized at all for the DRM_BRIDGE_ATTACH_NO_CONNECTOR case. Note that it6263_bridge_edid_read(), as the drm_bridge_funcs::edid_read callback, is supposed to be only called by bridge connector for the DRM_BRIDGE_ATTACH_NO_CONNECTOR case. So, pass the connector parameter from it6263_bridge_edid_read() to it6263_get_edid() and use it to get get EDID to avoid accessing the uninitialized connector. While at it, change the it6263_get_edid() function call in it6263_connector_get_modes() accordingly.
