Hi,

I'm having a problem where the DSS driver isn't restoring the
framebuffer parameters after going in and out of blanking with OFF
mode enabled. The problem appears to be in dss_get_ctx_id() in that
pdata->get_last_off_on_transaction_id is 0. Commenting out the call to
dss_need_ctx_restore() in dss_clk_enable() appears to do the right
thing. I'm using the current master branch of linux-omap.
You need to fill the func pointer in the board file:

static struct omap_dss_board_info xxx_dss_data = {
                 .get_last_off_on_transaction_id > omap_pm_get_dev_context_loss_count,
none of l-o board files seem to do this. I guess
with off capable master, we need this to be 
defaulted under CONFIG_PM within dss/core itself?
I mean the defaults prevent display function
at off, so why ask all boards to fill it up?

Nishanth Menon
