Cc: devicetree@vger.kernel.org Cc: phone-devel@vger.kernel.org Cc: Andy Shevchenko Cc: Jonathan Bakker Reviewed-by: Rob Herring Signed-off-by: Linus Walleij --- ChangeLog v5->v6: - Resend with the other patch. No changes. ChangeLog v4->v5: - Collect Rob's Reviewed-by tag. ChangeLog v3->v4: - Rename the bindings and file yas530 after the first introduced component in the family. - Simplify conditional logic using the if: not: YAML constructions. - Use the possibility to set a property to false to just remvove reset GPIOs and interrupts from variants that do not have them. ChangeLog v2->v3: - Restrict to cover the YAS53x variants, it turns out that YAS529 is a very different component from the others so keep that for a separate document when/if needed. - Rename the file and binding yamaha,53x.yaml - Use - if: clauses to restrict some properties. - Fix some spelling mistakes. - Restrict the nodename to be "magnetometer@[0-9a-f]" ChangeLog v1->v2: - Add Yamaha to the vendor list, I was surprised to find they were not yet listed. --- .../iio/magnetometer/yamaha,yas530.yaml | 112 ++++++++++++++++++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + 2 files changed, 114 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/magnetometer/yamaha,yas530.yaml diff --git a/Documentation/devicetree/bindings/iio/magnetometer/yamaha,yas530.yaml b/Documentation/devicetree/bindings/iio/magnetometer/yamaha,yas530.yaml new file mode 100644 index 000000000000..4b0ef1ef5445 --- /dev/null +++ b/Documentation/devicetree/bindings/iio/magnetometer/yamaha,yas530.yaml @@ -0,0 +1,112 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/magnetometer/yamaha,yas530.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Yamaha YAS530 family of magnetometer sensors + +maintainers: + - Linus Walleij + +description: + The Yamaha YAS530 magnetometers is a line of 3-axis magnetometers + first introduced by Yamaha in 2009 with the YAS530.
