Subject: [PATCH v5 2/3] arm64: dts: qcom: msm8998: Allow UFSHC driver to set-load
Date: Mon, 25 Feb 2019 13:17:44 +0100 [thread overview]
Message-ID: <66d35519-e4f8-b0c0-a4e4-4b4c8a01bd7f@free.fr> (raw)
In-Reply-To: <43768d77-80b7-9cdc-b6e0-08ec4a026c21@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.
