[PATCH v3 4/5] phy: qcom: qmp: Move qphy_setbits/clrbits/checkbits to common header

From: Krishna Chaitanya Chundru

Date: Wed Sep 09 2026 - 08:15:47 EST


qphy_setbits(), qphy_clrbits() and qphy_checkbits() were duplicated
verbatim across phy-qcom-qmp-pcie.c, phy-qcom-qmp-pcie-msm8996.c,
phy-qcom-qmp-ufs.c, phy-qcom-qmp-usb.c, phy-qcom-qmp-usbc.c and
phy-qcom-qmp-combo.c. Move them to the shared phy-qcom-qmp-common.h,
which all of these drivers already include, and drop the local copies.

This also makes the helpers available to phy-qcom-qmp-pcie-multiphy.c
without introducing yet another copy.
