Subject: [PATCH 2/4] clk: meson: regmap: export regmap_div ops functions
Date: Mon, 29 Jul 2019 15:16:54 +0200 [thread overview]
Message-ID: <20190729131656.7308-3-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190729131656.7308-1-narmstrong@baylibre.com>
The G12A CPU Clock Postmux divider needs a custom div_set_rate() call.
Export the clk_regmap_div_round_rate() and clk_regmap_div_recalc_rate()
to be able to override the default clk_regmap_div_set_rate() callback.
