2012-07-29fbdev: sh_mobile_lcdc: Fix vertical panning stepLaurent Pinchart1-6/+6
Commit 15dede882e564601947f2ce4b647742c0351be6d added support for horizontal panning but accidentally computes the Y pan step value incorrectly for NV12/21 and NV16/61 formats. Fix this.

2012-07-19fbdev: sh_mobile_lcdc: Fix pan offset computation in YUV modeLaurent Pinchart1-58/+52
The chroma plane offset in memory is equal to the luma plane maximum size. Fix offset computations. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-07-19fbdev: sh_mobile_lcdc: Fix overlay registers update during pan operationLaurent Pinchart1-0/+5
Updating overlay registers require switching to overlay update mode. This was correctly done when configuring the overlay format and size, but not when updating the base address registers during pan operation. Fix it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2012-07-19fbdev: sh_mobile_lcdc: Use channel configuration to initialize fb deviceLaurent Pinchart1-4/+6
Copy the x and y virtual resolutions from the channel information instead of recomputing them. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-07-19fbdev: sh_mobile_lcdc: Fix line pitch computationLaurent Pinchart1-8/+8
Line pitch depends on the virtual horizontal resolution, compute it accordingly. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-07-19fbdev: sh_mobile_lcdc: Destroy mutex at remove timeLaurent Pinchart1-2/+5
Add a missing mutex_destroy() call when the driver is unbound from the device. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-07-19sh_mobile_meram: Use direct function calls for the public APILaurent Pinchart1-17/+10
There's no reason to use abstract operation pointers to implement the MERAM API. Replace them by direct function calls. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-07-19sh_mobile_meram: Rename operations to cache_[alloc|free|update]Laurent Pinchart1-17/+15
The MERAM operations meram_register, meram_unregister and meram_update handle LCDC cache. In preparation for "raw" MERAM allocation, rename them to more appropriate names. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2012-06-20fbdev: sh_mobile_lcdc: Rename fb operation handlers with a common prefixLaurent Pinchart1-23/+25
Make all fb operation handlers start with sh_mobile_lcdc_ in preparation for the multi-plane support. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-06-20fbdev: sh_mobile_lcdc: Constify sh_mobile_lcdc_fix structureLaurent Pinchart1-1/+1
The structure is only read, make it const. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-05-21fbdev: sh_mobile_lcdc: Don't confuse line size with pitchLaurent Pinchart1-2/+3
When using the MERAM the LCDC line size needs to be programmed with a MERAM-specific value different than the real frame buffer pitch. Fix it.

2012-03-12fbdev: sh_mobile_meram: Remove unneeded sanity checksLaurent Pinchart1-4/+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>
2012-03-12fbdev: sh_mobile_meram: Don't perform update in register operationLaurent Pinchart1-3/+5
Remove the RGB or Y/C base address update from the meram_register() operation, as this belongs to the meram_update() operation. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Don't store copy of platform dataLaurent Pinchart1-36/+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>
2012-03-12fbdev: sh_mobile_meram: Allocate ICBs automaticallyLaurent Pinchart1-15/+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. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Pass channel pointer to sh_mobile_wait_for_vsyncLaurent Pinchart1-24/+23
The sh_mobile_wait_for_vsync() function isn't related to the fbdev API, make it generic by passing a channel pointer instead of an fb_info pointer. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Store configuration in channel structureLaurent Pinchart1-55/+54
Store the frame buffer configuration (colorspace, visible/virtual horizontal and vertical resolutions and line pitch) in the sh_mobile_lcdc_chan structure, and use it instead of accessing fb_info. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Pass physical device pointer to DMA functionsLaurent Pinchart1-2/+3
The dma_map_sg() and dma_unmap_sg() functions need a pointer to the physical device. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2012-03-12fbdev: sh_mobile_lcdc: Store the format in struct sh_mobile_lcdc_chanLaurent Pinchart1-11/+10
Store the active format in the channel structure, and use it instead of parsing info->var all over the place when the format is needed. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Add sh_mobile_format_info() functionLaurent Pinchart1-72/+102
The function returns a pointer to a structure describing a format based on its fourcc. Use the function where applicable instead of hardcoded switch-case statements. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Rename (lcd|num)_cfg (lcd|num)_modesLaurent Pinchart1-10/+10
The struct sh_mobile_lcdc_chan_cfg platform data contains a list of video modes. Name the lcd_cfg and num_cfg fields to reflect that they describe video modes. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Store display mode in a struct fb_videomodeLaurent Pinchart1-35/+39
Embed struct fb_videomode instead of struct fb_var_screeninfo in struct sh_mobile_lcdc_chan to store the display mode. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_hdmi: Don't access LCDC fb_infoLaurent Pinchart1-11/+13
The LCDC fb_info structure is only used to retrieve the default video mode in case none of the modes advertised by EDID information is acceptable. Pass a pointer to the default mode through the sh_mobile_lcdc_entity structure instead. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Pass a video mode to the notify callbackLaurent Pinchart1-17/+19
Pass pointers to struct fb_videomode and struct fb_monspecs instead of struct fb_var_screeninfo to the notify callback. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12sh_mobile_lcdc: Add display notify callback to sh_mobile_lcdc_chanLaurent Pinchart1-0/+84
The callback implements 3 notification events: - SH_MOBILE_LCDC_EVENT_DISPLAY_CONNECT notifies the LCDC that the display has been connected - SH_MOBILE_LCDC_EVENT_DISPLAY_DISCONNECT notifies the LCDC that the display has been disconnected - SH_MOBILE_LCDC_EVENT_DISPLAY_MODE notifies that LCDC that a display mode has been detected Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Return display connection state in display_onLaurent Pinchart1-1/+7

2012-03-12fbdev: sh_mobile_lcdc: Move pm runtime enable to probe()Laurent Pinchart1-18/+16
The pm_runtime_enable() and pm_runtime_resume() calls don't belong to sh_mobile_lcdc_setup_clocks(). Move them to the probe function. Remove the unneeded pm_runtime_resume() call. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2011-10-03video: irq: Remove IRQF_DISABLEDYong Zhang1-1/+1
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]).
