2013-11-11fbdev: shmobile-hdmi: Convert to clk_prepare/unprepareLaurent Pinchart
Turn clk_enable() and clk_disable() calls into clk_prepare_enable() and clk_disable_unprepare() to get ready for the migration to the common clock framework.

2011-06-15fbdev: sh_mobile_hdmi: fix regression: statically enable RTPMGuennadi Liakhovetski
A recent modification to the runtime PM code on mach-shmobile made a wrong RTPM implementation in the sh_mobile_hdmi driver apparent, which broke HDMI hotplug detection support on ap4evb. This patch does not implement a proper dynamic RTPM support for sh_mobile_hdmi, instead it restores the previous working state by statically enabling it.

2011-01-26console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn
The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

2011-01-11fbdev: sh_mobile_hdmi: add command line option to use the preferred EDID modeGuennadi Liakhovetski
Currently, if no command-line option is specified, the sh_mobile_hdmi will use the default 720p video mode. If a command line option of the form "video=sh_mobile_lcdc:<width>x<height>@<refresh>" is provided, the driver will look for that mode among those, available in the monitor EDID. This patch adds the ability to request the driver to use monitor's preferred mode by specifying 0 as width and hight in the above string. If that mode is not supported by the system, the driver will continue scanning through EDID modes, until it finds a suitable one.

With this patch hot-plugging of an HDMI or a DVI monitor can select a different video mode and reconfigure the LCDC and HDMI controllers accordingly. Due to a lack of a standard API to inform framebuffer users of a changed video mode, the framebuffer configuration is preserved regardless of a specific mode, selected for the monitor. As described in a previous patch, this leads to smaller framebuffers being displayed on larger monitors or a part of a larger framebuffer being displayed on a smaller resolution monitor.

2010-09-14fbdev: sh_mobile_hdmi: implement lockingGuennadi Liakhovetski
The SH-Mobile HDMI driver runs in several contexts: ISR, delayed work-queue, task context, when called from the sh_mobile_lcdc framebuffer driver. This creates ample race possibilities. Even though most these races are purely theoretical, it is better to close them. To trace fb_info validity we install a notification callback in the HDMI driver, and the only way for it to get to driver internal data is by using struct sh_mobile_lcdc_chan, therefore it had to be extracted into a separate common header.
