Subject: [PATCH v4 5/7] arm64: dts: qcom: msm8998: Allow drivers to set-load
Date: Fri, 8 Feb 2019 23:15:20 +0100 [thread overview]
Message-ID: <31519816-a641-ebfe-64c7-039aff074187@free.fr> (raw)
In-Reply-To: <09ce9c20-c47b-f936-a8a9-6c8ec8f0f867@free.fr>
The UFS host controller driver needs to set the load on 3 power rails
(l20, l26, s4) but the operation fails silently unless we specify the
regulator-allow-set-load property in the corresponding DT nodes.
