[PATCH v2 08/10] drm/imx: atomic phase 3 step 3: Legacy callback fixups

Tue May 31 09:24:29 UTC 2016
Now that we can use atomic configurations, all the legacy callbacks
of CRTCs, encoders and connectors can be switched to the atomic version.
For the imx-ldb driver, there is a clock parent setting mismatch bewteen
->enable and ->disable after the switch, so a fixup is added. For the
imx-tve driver, since the encoder's callback ->dpms is replaced by
->disable, we need to move the setting for the IPU_CLK_EN bit(in register
TVE_COM_CONF_REG) from ->enable/->disable to ->mode_set, otherwise, the
relevant CRTC cannot be disabled correctly with a warning on DC stop timeout.
Signed-off-by: Liu Ying <gnuiyl at gmail.com>

v1->v2:
* A fixup on the TVE register bit IPU_CLK_EN to avoid a warning on DC
stop timeout when doing mode setting.
