Currently we are using "automatic" frame change event generation. The event is generated by any access to plane or pipe registers. We have option to use "PSR PR Frame Change Enable" bit in TRANS_PUSH register to enable frame change event generation on trans push. When this bit is set "automatic" frame change event generation doesn't work anymore. This patch set is taking trans push mechanism into use.
