[PATCH v5 5/5] iio: humidity: si7020: add No Hold read mode

The Si7013/20/21 modules support 2 read modes: * Hold mode (blocking), where the device stretches the clock until the end of the measurement * No Hold mode (non-blocking), where the device replies NACK for every I2C call during the measurement Here the No Hold mode is implemented, selectable

Hi Wolfram, Thank you for the patch. I'm afraid this doesn't make any noticeable difference. With or without the patch applied the adv7511 can't be detected using the latest driver tag (renesas-devel-20151026-v4.3-rc7). However, I have a bit more information to report. First of all, I got
