Subject: [PATCH 0/5] Add LPASS LPI pin controller support for SM6350
Date: Wed, 28 Jan 2026 13:26:48 +0100 [thread overview]
Message-ID: <20260128-sm6350-lpi-tlmm-v1-0-36583f2a2a2a@fairphone.com> (raw)
Introduce support for the LPASS LPI pin controller for the Qualcomm
SM6350 SoC, by adding the dt-bindings, driver, dts bits and enabling it
in the arm64 defconfig.
The custom slew offset for gpio14 is described as
"qcom,lpi-slew-base-tbl" in the downstream dts[0]. I've tried to find
some reasonable solution to have this handled correctly in the patches
here, but suggestions are welcome how to improve the situation. There's
of course several ways to implement a solution for this.
