Subject: [PATCH 1/8] dt-bindings: power: supply: Add DT schema for Qualcomm SMBCHG
Date: Mon, 8 Aug 2022 08:34:52 +0100 [thread overview]
Message-ID: <20220808073459.396278-2-y.oudjana@protonmail.com> (raw)
In-Reply-To: <20220808073459.396278-1-y.oudjana@protonmail.com>
From: Yassine Oudjana <y.oudjana@protonmail.com>
Add DT schema for the switch-mode battery charger found on Qualcomm
PMICs such as PMI8994. Due to lack of documentation, some interrupt
descriptions might be inaccurate.
