2009-11-26mfd: glamo: Enable FIFO stage for the LCD engine's memory accessThomas White
By avoiding conflicts of memory access inside Glamo, this doubles the speed of internal memory access. Signed-off-by: Thomas White <taw@bitwiz.org.uk> Signed-off-by: Paul Fertser <fercerpav@gmail.com>

2009-06-13gta02: move debugging messages to the appropriate levelsPaul Fertser
Clean up debugging messages so that we don't see any output with loglevel=4 (default for Qi). This avoids slowing down suspend/resume by slow fb output. Checkpatch barks on this patch but i guess most of that debugging would have to be changed prior to upstream submission anyway. Signed-off-by: Paul Fertser <fercerpav@gmail.com>
2009-06-02Reorganise memory map (again)Thomas White

To disable the workaround at run-time run: echo 0 > /sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-regltr.9/glamo3362.0/glamo-fb.0/xglamo_hack I guess I should add a compile option now to completely disable the workaround but let's call this an enhancement and let's close the bug now. By default the workaround is enabled. Signed-off-by: Nelson Castillo <arhuaco@freaks-unidos.net> Reported-by: Timo Juhani Lindfors <timo.lindfors@iki.fi>

2009-04-19Revert "Fixed the LCM driver state transition delay and pixel clock issue"Nelson Castillo
This reverts commit bd4b7e8e84ab43a13a4620b001d52d373c2122b3 which brought WSOD back for some devices. It was reported that the problem does not happen with Qi and it seem it is good news. See: https://docs.openmoko.org/trac/ticket/2274 Conflicts: drivers/video/display/jbt6k74.c
2009-04-05Fixed the LCM driver state transition delay and pixel clock issueNicolas Dufresne
Space transition between sleep-in and sleep-out of at least 120 ms as mentionned in the spec. Also, made sure the LCM is moved into sleep state before the pixel clock is turned off. To do so, I've modified glamo-fb to send FB_BLANK_POWERDOWN before turning off the pixel clock. Also fixed various violation of coding style. This patch should reduce the risk of white screen.

2009-03-26Import part of Thomas White DRM tree:Jorge Zapata
Handle new memory layout. The "not-needed" memory should not be taken by the framebuffer driver. Use that for the DRM driver. Add the cmdq platform device Set aside 4k for hardware cursor, reject cursors that don't fit.

It looks like I made a mistake in the original pan implementation that is now getting exercised. The following fixes pan again. Cheers, Sean

2008-11-19debug-resume-hang.patchAndy Green
Weeks of frantic effort to control Glamo, traced the issue to two outcomes: nWAIT is forced down and the device is hard locked, or we survive immediate Glamo resume and die again with nWAIT forced down when the framebuffer driver tries to flash the soft cursor.

2008-11-19fix-glamofb-remove-soft-delays.patchAndy Green
The delay versions of the access to registers were based on a misunderstanding of the Glamo docs: it can force nWAIT differently depending on the access type. Therefore we don't need to take special care about delays on CPU side. Signed-off-by: Andy Green <andy@openmoko.com>

2008-11-19glamo_fb: Implement screen blankingHarald Welte
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.
