CONFIG_OMAP2_DSS_SLEEP_BEFORE_RESET: Sleep 50ms before DSS reset

General informations

The Linux kernel configuration item CONFIG_OMAP2_DSS_SLEEP_BEFORE_RESET:

• prompt: Sleep 50ms before DSS reset
• type: bool
• depends on: (none)
• defined in drivers/video/omap2/dss/Kconfig
• found in Linux kernels: 3.0

Help text

For some unknown reason we may get SYNC_LOST errors from the display subsystem at initialization time if we don't sleep before resetting the DSS. See the source (dss.c) for more comments.

However, 50ms is quite long time to sleep, and with some configurations the SYNC_LOST may never happen, so the sleep can be disabled here.
