Hi, we use the AD7873 controller with internal reference. The current implementation for AD7873 in the ads7846 driver forces the vref to switch off after every sample. So measurements especially in the edge of the screen become unreliable due to the settling time for the internal reference (I guess). Is there a special reason to override the "keep_vref_of" setting of the platform data for the AD7873 in ads7846_setup_spi_msg? We did already some tests and found out, that leaving vref on makes out system usable with AD7873.
