From fbac26b9ad21f1311136e3dd9b342d693062cddc Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sat, 31 Oct 2020 18:12:37 +0000 Subject: dt-bindings:iio:afe:current-sense-amplifier: txt to yaml conversion. Note this includes a fix in the example where we had *-mul instead of *-mult. The binding doc and driver agree that it should be *-mult Signed-off-by: Jonathan Cameron Reviewed-by: Rob Herring Cc: Peter Rosin Link: https://lore.kernel.org/r/20201031181242.742301-6-jic23@kernel.org --- .../bindings/iio/afe/current-sense-amplifier.txt | 26 ----------- .../bindings/iio/afe/current-sense-amplifier.yaml | 54 ++++++++++++++++++++++ 2 files changed, 54 insertions(+), 26 deletions(-) delete mode 100644 Documentation/devicetree/bindings/iio/afe/current-sense-amplifier.txt create mode 100644 Documentation/devicetree/bindings/iio/afe/current-sense-amplifier.yaml (limited to 'Documentation') diff --git a/Documentation/devicetree/bindings/iio/afe/current-sense-amplifier.txt b/Documentation/devicetree/bindings/iio/afe/current-sense-amplifier.txt deleted file mode 100644 index 821b61b8c542..000000000000 --- a/Documentation/devicetree/bindings/iio/afe/current-sense-amplifier.txt +++ /dev/null @@ -1,26 +0,0 @@ -Current Sense Amplifier -======================= - -When an io-channel measures the output voltage from a current sense -amplifier, the interesting measurement is almost always the current -through the sense resistor, not the voltage output.
