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.

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

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: Don't pass struct device aroundLaurent Pinchart1-20/+21
Pass a pointer to a struct sh_mobile_lcdc_priv instead, which stores a pointer to the device. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
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>
2012-03-12fbdev: sh_mobile_lcdc: Mark init-only symbols with __devinit(const)Laurent Pinchart1-2/+2
default_720p and sh_mobile_lcdc_check_interface are used at device initialization time only. Mark them as __devinitconst and __devinit respectively. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Reorder code into sectionsLaurent Pinchart1-190/+231

2011-10-31video: Add module.h to drivers/video files who really use it.Paul Gortmaker1-0/+1
They were getting this implicitly by an include of module.h from device.h -- but we are going to clean that up and break that include chain, so include module.h explicitly now. [ with contributions from Axel Lin <axel.lin@gmail.com> ] Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.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]). So now this flag is a NOOP and can be removed.

2011-09-05fbdev: sh_mobile_lcdc: Remove sh_mobile_lcdc_set_bpp()Laurent Pinchart1-70/+17
The function duplicates code found in sh_mobile_check_var(). Remove sh_mobile_lcdc_set_bpp() and call sh_mobile_check_var() instead. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
2011-09-05fbdev: sh_mobile_lcdc: Split channel initialization from probe functionLaurent Pinchart1-118/+129
Move channel initialization to sh_mobile_lcdc_channel_init() and call the function from sh_mobile_lcdc_probe(). This makes the code more readable and prepares it for fix/var initialization rework.

2011-08-19fbdev: sh_mobile_lcdc: Restart LCDC in runtime PM resume handlerLaurent Pinchart1-44/+5
Instead of restoring registers blindly, restart the LCDC by going through the startup sequence when resuming from runtime PM suspend. All registers are now correctly initialized in the right order. As a side effect, this also gets rid fo a possible panning restore issue caused by always saving the frame buffer base address registers from set A instead of the currently active set. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2011-08-19fbdev: sh_mobile_lcdc: Store the frame buffer base address when panningLaurent Pinchart1-13/+9
When the frame buffer base address is changed by a panning operation, store it in the channel structure. It will be reused when runtime PM code will use __sh_mobile_lcdc_start(). Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2011-08-19fbdev: sh_mobile_lcdc: Split LCDC start code from sh_mobile_lcdc_startLaurent Pinchart1-158/+151
Splitting the LCDC start code from clock, MERAM and panel management will make the code usable by runtime PM. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2011-08-19fbdev: sh_mobile_lcdc: Compute clock pattern using divider denominatorLaurent Pinchart1-4/+6
The clock divider pattern is computed based on the dot clock register value which stores the divider denumerator. However, when using a 1:1 divider ratio, the register is programmed with a value that must not be interpreted as a denominator. This results in a shift left operation with a value of 32, which produces undefined behaviour. Compute the clock pattern using the divider denominator, not the dot clock register value.

2011-08-19fbdev: sh_mobile_lcdc: Don't acknowlege interrupts unintentionallyLaurent Pinchart1-12/+8
The LDINTR register caries both interrupt enable and interrupt status bits. When setting or clearing interrupt enable bits, write all status bits to 1 to avoid acknowledging interrupts by mistake. When acknowledging interrupts, write 1 to all non-triggered interrupt bits to avoid losing interrupts. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2011-08-19fbdev: sh_mobile_lcdc: Replace hardcoded register values with macrosLaurent Pinchart1-111/+93
Instead of hardcoding register values through the driver, define macros for individual register bits using the register name and the bit name, and use the macros. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2011-08-19fbdev: sh_mobile_lcdc: Turn dot clock on before resuming from runtime PMLaurent Pinchart1-3/+3
Resuming from runtime PM restores all LCDC registers. If the dot clock is off at that time display panning information will be corrupted. Turn the dot clock on before resuming from runtime PM. Similarly, turn the clock off after suspending the LCDC. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Tested-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de>
2011-08-19fbdev: sh_mobile_meram: Enable/disable MERAM along with LCDCDamian Hobson-Garcia1-0/+4
