Subject: dt-bindings: bluetooth: qcom,wcn3990-bt: Split to separate schema
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=77f1835364c86a660b7d95b69c598d6373c4f13f;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: bluetooth: qcom,wcn3990-bt: Split to separate schema

One big Qualcomm Bluetooth schema is hardly manageable: it lists all
possible properties (19 supplies).  Split qcom,wcn3990-bt to separate
bindings, so device schema will be easier to read/maintain and list only
relevant properties.

This binding is very similar to qcom,wcn3950-bt, however devices have
additional VDD_CH1 supply.
