Subject: [PATCH v2 03/17] clk: BD718x7: Do not depend on parent driver data
Date: Tue, 19 Jan 2021 09:15:17 +0200 [thread overview]
Message-ID: <bfe41e384fba1cc340ac0d9c8a033d3f91776ed8.1611037866.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1611037866.git.matti.vaittinen@fi.rohmeurope.com>
The bd718x7 only needs a regmap from parent device. This can be
obtained by call to dev_get_regmap. Do not require parent to
populate the driver data for this.
