Problem with DSS clocks & accessing registers

2011-03-07 Thread Tomi Valkeinen
Hi Kevin, Paul, We currently have a small problem with OMAP4 DSS. When we enable the DSS clocks, it seems that the DSS registers are not always accessible right after the clock enable. I understood that on OMAP4 the clock framework doesn't guarantee that the registers are accessible after enablin
