Throughout the night, omap2_mcspi has consumed a reasonable amount of CPU while the phone was idle. At midnight it was at about 0.02% (nothing to worry about here) and at about 3pm started rising to 3.0% where it stayed until I unplugged it. The process only consumed CPU if the phone was plugged in. I'm not concerned about battery usage, but am curious what this process does. A few google searches didn't return anything. Any ideas?
