2009-07-01Nasty jbt stuffThomas White
This adds a stopgap measure to permit manipulation of the LCD controller chip in the absence of an fb notifier chain. It also adds some messing around with the DPMS stuff. Signed-off-by: Thomas White <taw@bitwiz.org.uk>

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.

2009-03-02Fixed corruption of LCM registersNicolas Dufresne
Some registers where not set properly, or at the right time (thanks to Balaji for his patch). Weak locking could lead to corruption when using sysfs to switch state from multiple threads or processes. The state transitions are now all atomic. The driver attribute 'last_state' was used for same purpose of 'normal_state'. Kept only 'normal_state' and used it in 'init_regs' instead of custom qvga parameter. This patch should fix bug #2235.

Hi Andy, Here's the fix for the qvga-normal bug we observed the other day here - when the screen is powered up again after a blanking, in qvga-normal mode, we see a WSOD(kind of!)

2008-11-19fix-pcf50633-kill-white-splash-of-death-on-suspend.patchAndy Green
mach-gta02 meddles with the regulator platform struct after it is defined, leading to LCM power getting lost in suspend despite I set it to be left up. Fixing this finally removes the incredibly stubborn white LCM on suspend "flash". This is also going to be implicated in Sean McNeil's experience of monochromatic LCM after resume, which was previously attacked by resetting and re-initing the LCM from scratch. In addition, I realized that we take down core_1v3 in pcf50633 suspend action, this is happening near the start of suspend, so we are in a meta-race to finish suspend in a controlled way before the caps on core_1v3 run out (I only saw 23.3uF total). If it's true, this is where the weirdo sensitivity to timing during suspend is coming from. Therefore in this patch we also remove sleeps and dev_info() etc (which have to flush on serial console) from the pc50633 isr workqueue if we are in pcf50633 driver suspend state 1, ie, suspending... because we don't have time for it.

2008-11-19change-lcm-keep-power-faster-resume.patchAndy Green

2008-11-19add-use-pcf50633-resume-callback-jbt6k74.patchAndy Green
Adds the resume callback stuff to glamo, then changes jbt6k74 to no longer use a sleeping workqueue, but to make its resume actions dependent on pcf50633 and glamo resume (for backlight and communication to LCM respectively) Signed-off-by: Andy Green <andy@openmoko.com>
2008-11-19fix-suspend-backlight-timing-pm-debug.patchAndy Green
This patch improves the smoothness of suspend and resume action. Taking out CONFIG_PM_DEBUG allows much more rapid resume (the low level serial traffic appears to be synchronous) Added a platform callback in jbt driver and support in pcf50633 so we can defer bringing up the backlight until the LCM is able to process video again (which must happen after the glamo is up and producing video beacuse the LCM is hooked to glamo SPI) GTA01 should not be affected by all this as the callback will default to null and it is on pcf50606 Signed-off-by: Andy Green <andy@openmoko.com>

This driver adds support for the SPI-based control interface of the LCM (LCD Panel) found on the FIC GTA01 hardware. The specific panel in this hardware is a TPO TD028TTEC1, but the driver should be able to drive any other diplay based on the JBT6K74-AS controller ASIC.

2008-05-20fbdev: fix race in device_createGreg Kroah-Hartman
There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata().
