-Subject: [PATCH] glamo_fb: Implement screen blanking
-
-This patch implements fb_blank() for the glamo-fb driver, which switches off
-the pixel clock (DCLK) for power saving.
-
-We currently delay the actual pixel clock switch until we enter
-FB_BLANK_POWERDOWN, since the backlight fade is slow and we don't want the
-user to see artefacts on the screen while the backlight is fading out.
-
-So since the X server first sends FB_BLANK_{V,H}SYNC_SUSPEND, we start the
-backlight fade here, and only once we get FB_BLANK_POWERDOWN the pixel clock is
-disabled.
-
-There are no measurements yet, but the power savings should be double, since
-there is no longer any  generation of the high-frequency LCM signals, and
-there are no video-related SDRAM accesses anymore.
-
