Subject: [PATCH v3 2/5] arm64: dts: qcom: msm8998: Allow drivers to set-load
Date: Mon, 4 Feb 2019 18:37:16 +0100 [thread overview]
Message-ID: <31108a78-e158-5147-2f2f-cd300cb5d49b@free.fr> (raw)
In-Reply-To: <e3c82a49-c601-effc-348f-f768656c659f@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.
