Subject: [PATCH platform-next v1 7/8] platform_data/mlxreg: Add presence register field for FAN devices
Date:   Mon,  1 Jun 2020 12:18:50 +0300
Message-Id: <20200601091851.5491-8-vadimp@mellanox.com>
In-Reply-To: <20200601091851.5491-1-vadimp@mellanox.com>
References: <20200601091851.5491-1-vadimp@mellanox.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add new field 'reg_prsnt' to the structure 'mlxreg_core_data' to
provide the number FAN drawers equpped within the system. The purpose
is to allow mapping between FAN drawers and FAN rotors (tachometer),
since FAN drawer can be eqipped with a few rotors.
