* | mdss: display: add dsi dynamic clock controlKuogee Hsieh2016-03-23
| | | | | | | | | | | | | | | | | | | | | | This patch adds dsi dynamic clock control support which is based on reference count. Both dsi clock and mdp clock are controlled together during screen update except dsi dcs command which needs to control dsi clock independent of screen update.

* | mdss: display: add cmdlist to tx/rx dcs commandKuogee Hsieh2016-03-23
| | | | | | | | | | | | | | | | | | Since dsi link is a shared resource between pixel stream and dcs command, it needs a mechanism to protect dsi link to be accessed exclusively. cmdlist is introduced for this purpose in this patch.

* | mdss: display: add 16 bits length dcs command supportKuogee Hsieh2016-03-23
| | | | | | | | | | | | | | | | | | | | | | current implemtation only supports 8 bits of dcs length. This patch adds support of 16 bits dcs length as specified at dcs standard. Therefore all dcs related tx/rx functions are needed be updated. In addition, all dsi panel dtsi files are need to be updated too since it contains dcs header.

* | msm: mdss: flush ongoing hpd work before turning hpd offUjwal Patel2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | Since hpd off and hpd interrupt work are always in different contexts, in a very strict timing window it is possible that hpd off is scheduled the middle of hpd interrupt work. If this happens, when hpd interrupt work resumes after hpd off is serviced, un-clocked register access may lead to unknown outcome. Counter this situation by flushing the hpd interrupt work, if any, before calling hpd off.

| | | | | | | | | | | | | | | | | | | | | | | | | | Any register access within MDP domain requires mdss ahb and mdp core clocks to be enabled. In the use-case where HDMI is the only sub-module enabled and its interrupt is triggered, lack of mdp core clock leads to un-clocked access to MDSS interrupt register. Which in turn leads to ahb bus timeout and device crash or reboot. Fix this by controlling mdp core clock from HDMI driver.
