Subject: [PATCH v2 4/4 net-next] net: mdio device: use flexible sleeping in reset function
Date: Thu, 30 Jul 2020 21:57:49 +0200
Message-ID: <20200730195749.4922-5-bruno.thomsen@gmail.com> (raw)
In-Reply-To: <20200730195749.4922-1-bruno.thomsen@gmail.com>

MDIO device reset assert and deassert length was created by
usleep_range() but that does not ensure optimal handling of
all the different values from device tree properties.
By switching to the new flexible sleeping helper function,
fsleep(), the correct delay function is called depending on
delay length, e.g. udelay(), usleep_range() or msleep().
