* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-272-1/+21
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

| * video: Add Video Pipeline (VPL) supportSascha Hauer2015-07-132-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complex video pipelines are modelled with the of_graph bindings in the devicetree. This patch adds a ioctl infrastructure to issue commands to the remote endpoint of a of_graph. Currently defined ioctls are prepare/unprepare, enable/disable and get_modes. This is enough to control LVDS or HDMI encoder or simple panels. A device node which contains of_graph endpoints can be registered as a VPL entity. An entity can receive ioctls via the .ioctl callback and also issue ioctls by calling vpl_ioctl. The core itself will never iterate over the entire pipeline. Instead, the different VPL entities should forward an ioctl to the next instance in the pipeline whenever necessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
