From: André Draszik Date: Thu, 22 Jan 2026 15:43:37 +0000 (+0000) Subject: regulator: add REGULATOR_LINEAR_VRANGE macro X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7d33c0a4c6a3356db2b2f599820baf75d3753d44;p=thirdparty%2Fkernel%2Flinux.git regulator: add REGULATOR_LINEAR_VRANGE macro REGULATOR_LINEAR_VRANGE is similar to REGULATOR_LINEAR_RANGE, but allows a more natural declaration of a voltage range for a regulator, in that it expects the minimum and maximum values as voltages rather than as selectors. Using voltages arguably makes this macro easier to use by drivers and code using it can become easier to read compared to REGULATOR_LINEAR_RANGE.
