This patch fixes the LCDC driver to avoid calling the function sh_mobile_lcdc_start_stop(priv, 0) unless the same function has been called before to start the LCDC hardware. Triggered when sh_mobile_lcdcfb.c failed to probe() due to missing MSTP clocks. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch adds suspend/resume support to the LCDC driver for SuperH Mobile - sh_mobile_lcdcfb. We simply stop hardware on suspend and start it again on resume. For RGB panels this is trivial, but for SYS panels in deferred io mode this becomes a bit more difficult - we need to wait for a frame end interrupt to make sure the clocks are balanced before stopping the actual hardware.

Fix deferred io cleanup patch in the sh_mobile_lcdcfb driver. If probe() fails early the sh_mobile_lcdc_stop() function will be called to clean up deferred io. This patch modifies the code to only call fb_deferred_io_cleanup() after deferred io has been initialized. With this patch applied we no longer hit BUG_ON() inside fb_deferred_io_cleanup(). Triggers on a Migo-R with the SYS QVGA panel board unmounted. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch adds sh_mobile_lcdcfb deferred io support for SYS panels. The LCDC hardware block managed by the sh_mobile_lcdcfb driver supports RGB or SYS panel configurations. SYS panels come with an external display controller that is resposible for refreshing the actual LCD panel. RGB panels are controlled directly by the LCDC and they need to be refreshed by the LCDC hardware. In the case of SYS panels we can save some power by configuring the LCDC hardware block in one-shot mode. In this one-shot mode panel refresh is managed by software. This works well together with deferred io since it allows us to stop clocks for most of the time and only enable clocks when we actually want to trigger an update. When there is no fbdev activity the clocks are kept stopped which allows us to deep sleep. The refresh rate in deferred io mode is set using platform data. The same platform data can also be used to disable deferred io mode. As with other deferred io frame buffers user space code should use fsync() on the frame buffer device to trigger an update.

Since the sh_mobile_lcdc hardware has the framebuffer(s) in system RAM, use FB_SYS instead of FB_CFB. Also hook in read and write helpers. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This provides a workaround for users of sh_mobile_lcdcfb that don't define HAVE_CLK and have otherwise sane clock initialization. At the same time, move the sh_mobile_lcdc.h header to include/video/. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This is the SuperH Mobile LCDC frame buffer driver V2, adding support for the LCDC block found in SuperH Mobile processors. The hardware supports up to two LCD panels per LCDC block, and both RGB and SYS interfaces can be used to hook up LCD panels/modules. The device driver is a regular platform driver, so LCD configuration and board specific hooks are passed to the driver using platform data. LCD modules using SYS interface often require special configuration using the SYS bus, and to solve this cleanly the driver provides SYS interface operations to the board code. Tested on sh7723 and sh7722 processors with a SYS16A QVGA panel and WVGA panels using RGB16 and RGB18 interfaces.
