* fbdev: sh_mobile_lcdc: Rename (lcd|num)_cfg (lcd|num)_modesLaurent Pinchart2012-03-122-29/+29
| | | | | | | | 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>
* fbdev: sh_mobile_lcdc: Store display mode in a struct fb_videomodeLaurent Pinchart2012-03-122-36/+44
| | | | | | | 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>
* fbdev: sh_mobile_hdmi: Don't access LCDC fb_infoLaurent Pinchart2012-03-123-31/+28
| | | | | | | | | 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>
* fbdev: sh_mobile_hdmi: Don't set sh_hdmi::mode in the display on handlerLaurent Pinchart2012-03-121-7/+1
| | | | | | | | The struct sh_hdmi mode field is only used after being assigned by the EDID read code. There is thus no need to initialize it from the LCDC display var in the display on handler. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
* fbdev: sh_mobile_lcdc: Pass a video mode to the notify callbackLaurent Pinchart2012-03-123-50/+48

* sh_mobile_hdmi: Use LCDC notification callbackLaurent Pinchart2012-03-121-77/+14
| | | | | | | | Instead of accessing the LCDC channel and fb_info structures directly, use the LCDC notification callback to inform the LCDC driver about display-related events. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
* sh_mobile_lcdc: Add display notify callback to sh_mobile_lcdc_chanLaurent Pinchart2012-03-122-0/+94
| | | | | | | | | | | | | 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>

* video: s3c-fb: Add support EXYNOS5 FIMDJingoo Han2012-03-061-5/+47
| | | | | | | | | | | | | | | | This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5 and adds extended timing control setting. EXYNOS5 FIMD needs extended setting for video timing control. Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and VIDOSDxB registers in order to set timing value for lager resolution. Also, address offset of VIDTCONx registers is changed from 0x0 to 0x20000, thus variable type should be changed to int type to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

But now they are actually 20 bit. So the fix is simplicity itself. I've tested with 300 devices and all user-mode utils work just fine. I have also mechanically added 10,000 to the ida (so devices are /dev/osd10000, /dev/osd10001 ...) and was able to mkfs an exofs filesystem and access osds from user-mode. All the open-osd user-mode code uses the same library to access devices through their symbolic names in /dev/osdX so I'd say it's pretty safe. (Well tested) This patch is very important because some of the systems that will be deploying the 3.2 pnfs-objects code are larger than 64 OSDs and will stop to work properly when reaching that number.

The corresponding registers are then read-only. If the user tries it nonetheless, error out with EINVAL instead of silently doing nothing.

Make the driver detect the latter mode, and expose the different modes in sysfs as per pwm_enable, so that the user can switch between them. The interpretation of the pwm_enable attribute for the F75387 is adjusted to be a superset of those values used for similar Fintek chips which do not support automatic duty mode, with 2 mapping to automatic speed mode, and moving automatic duty mode to the new value 4. Toggling the duty mode via pwm_enable is currently denied for the F75387, as the chip then simply reinterprets the fan configuration register values according to the new mode, switching between RPM and PWM units, which makes this a dangerous operation. This patch introduces a new pwm mode into the driver. This is necessary because the new mode (automatic pwm mode, 4) may already be enabled by the BIOS, and the driver should not break existing functionality. This was seen on at least one board.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the F75387, the register holding the current PWM duty cycle value is r/o; changing it requires writing to the fan expect register instead.
