mfd: STMPExxxx fixes and touch screen support
Hi Rabin, I merged your stmpexxx patches and tested them on my board with a stmpe811 chip (gpio + touchscreen). In the following are few fixes for the gpio driver. In the serie is also the V4 of my stmpe touchscreen driver, which is now converted to the stmpexxx core. There appears to be two stmpe variants wit... 24 Jun 2010 07:26
