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@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.
