This is necessary because of parasitic capacities on different systems. In the last patch there is a fix of dtc warning if someone is using the given example Changes against v3: - added suggestion of Rob to rename the new attribute to clock-frequency Changes against v2: - added suggestion of Jonathan to add vendor prefix in device tree setting Andreas Klinger (3): iio: hx711: add clock-frequency property in DT iio: hx711: add delay until DOUT is ready iio: hx711: warning in dt binding example doc .../devicetree/bindings/iio/adc/avia-hx711.txt | 12 +++++++- drivers/iio/adc/hx711.c | 33 ++++++++++++++++++++++ 2 files changed, 44 insertions(+), 1 deletion(-) -- 2.1.4
