[PATCH 1/3] dt-bindings: iio: adc: stm32: add analog switches supply control

2019-06-12 Thread Fabrice Gasnier
On stm32h7 and stm32mp1, the ADC inputs are multiplexed with analog switches which have reduced performances when their supply is below 2.7V (vdda by default). Add documentation for optional vdda-supply & vdd-supply that can be used to supply analog circuitry (controlled by syscfg bits). Signed-o
