* fbdev: sh_mobile_lcdc: fixup B side hsync adjust settingsKuninori Morimoto2013-03-271-0/+1
| | | | | | | | | | | | | | The lcdc B side horizon output is shifted if sh_mobile_lcdc_pan() was called. This patch fixup this issue. It is tested on R8A7740 Armadillo800eva HDMI output.

* Drivers: video: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-9/+9
| | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* fbdev: sh_mobile_lcdc: Store the backlight brightness internallyLaurent Pinchart2012-11-211-1/+2
| | | | | | | | There's no need to query the hardware for the currenty brightness value through a platform data callback when we can cache the value internally in the LCDC driver. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
* fbdev: sh_mobile_lcdc: Remove priv argument from channel and overlay initLaurent Pinchart2012-11-211-18/+17

* fbdev: sh_mobile_lcdc: use dma_mmap_coherentHideki EIRAKU2012-11-211-0/+20
| | | | | | | | | | fb_mmap() implemented in fbmem.c uses smem_start as the physical address of the frame buffer. In the sh_mobile_lcdc driver, the smem_start is a dma_addr_t that is not a physical address when IOMMU is enabled. dma_mmap_coherent() maps the address correctly.

| | | | | | | | | Commit 15dede882e564601947f2ce4b647742c0351be6d added support for horizontal panning but accidentally computes the Y pan step value incorrectly for NV12/21 and NV16/61 formats.

* fbdev: sh_mobile_meram: Remove unneeded sanity checksLaurent Pinchart2012-03-121-4/+1
| | | | | | | | | | | | The meram_register(), meram_unregister() and meram_update() operations check that the pointers they get from the caller are not NULL. Those checks can be remove, as the caller already ensures that the pointers are valid. The platform sanity checks can also be removed, as the operations can't be accessed without valid platform data anyway. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

* fbdev: sh_mobile_lcdc: Don't store copy of platform dataLaurent Pinchart2012-03-121-36/+35
| | | | | | | | | | Instead of copying the whole platform data structure to struct sh_mobile_lcdc_chan, store a const pointer to the channel platform data. MERAM configuration information needs to be changed at runtime, so copy it to struct sh_mobile_lcdc_chan. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
* fbdev: sh_mobile_meram: Allocate ICBs automaticallyLaurent Pinchart2012-03-121-15/+12
| | | | | | | | | | | | Instead of manually specifying the ICBs to use in platform data, allocate them automatically at runtime. The range of reserved ICBs (for instance to be used through UIO), if any, is passed in the platform data reserved_icbs field as a bitmask. The MERAM registration function now returns a pointer to an opaque MERAM object, which is passed to the update and unregistration functions.
