| * OMAP: DSS2: don't power off a panel twiceStanley.Miao2010-10-226-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If we blank the panel by echo 1 > /sys/devices/platform/omapfb/graphics/fb0/blank Then, we reboot the sytem, the kernel will crash at drivers/video/omap2/dss/core.c:323 This is because the panel is closed twice.

| | * OMAP: DSS2: Replace strncmp() with sysfs_streq() in overlay_manager_store()Archit Taneja2010-08-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function overlay_manager_store currently fails if the sysfs input is a prefix string of an existing overlay manager name. This occurs because strncmp compares the two strings only till the length of the input sysfs string. So a sysfs input "lcd" will match manager name "lcd2" which is incorrect behavior. The use of sysfs_streq here will prevent this false positive match to occur. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

| | * OMAP: DSS2: adjust YUV overlay width to be evenTomi Valkeinen2010-08-051-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An overlay in YUV mode has to have an even input width, because data for each pixel is divided between two adjacent pixels. The algorithm handling manual update overlay adjusting may adjust the overlay width to be odd. This patch adds a check for that situation, and makes the width even. The width is increased by one if it is possible (the unadjusted input width is larger than the width), and decreased by one if increasing is not possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP DSS HW cannot send updates with odd widths. Normally the widths are made even while preparing the update. This patch adds a BUG_ON() to check if the update width is even. This is to detect broken updates cleanly, as otherwise the OMAP DSS HW will just halt, leading to obscure error situations.

| | * OMAP: DSS2: DSI: increase FIFO low thresholdTomi Valkeinen2010-08-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current FIFO low threshold was too low, and caused the FIFO to run empty when core domain went to INA state between FIFO fills. This patch increases the low threshold to keep that from happening. The threshold values depend quite much on the HW and the use cases, so this should actually be somehow configurable from board files, perhaps. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

| | | | | | | | | | | | | | | | | | | | | | | | SMRPS function always sent BTA after sending the SMRPS packet. This is not needed, and also caused some (buggy) panels to bug. This patch removes the BTA. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>

| | | | | | | | | | | | | | | | | | | | | | | | Currently the update area on manual update displays is automatically enlargened to fully cover scaled overlays.

| | * OMAP: DSS2: DSI: use BTA to end the frame transferTomi Valkeinen2010-08-052-63/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously a work was started on FRAMEDONE interrupt, and this work either sent a BTA synchronously or looped until TE_SIZE was zero, to wait for the end of the transfer. This patch changes a BTA to be sent asynchronously from FRAMEDONE interrupt, and when a BTA interrupt is received, the transfer is finished. This way we do the whole process asynchronously, and also inside interrupt context. This will give us much better latency to handle the end of the frame than with the previous work based solution.

| | * OMAP: DSS2: DSI: change dsi_vc_config_l4/vp()Tomi Valkeinen2010-08-051-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change dsi_vc_config_l4/vp() to loop for the VC_BUSY flag to change, and return an error if it fails. Busy looping is bad, but there's no interrupt that can be used for all the cases where VC can be busy. So the caller should first try to make sure that the VC is not busy, if possible, and then call dsi_vc_config_l4/vp(). Most notable case when the caller cannot be sure if the VC is busy is after frame has been sent. Usually DSI buffers have been emptied until we need to reconfig the VC, but in some rare cases the VC can still be busy, and this patch will handle that case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TRM tells us to wait for the DSI PLL derived clocks to become active before selecting them for use.
