Subject: [PATCH v2 07/91] clk: bcm: rpi: Use clk_hw_register for pllb_arm
Date: Fri, 24 Apr 2020 17:33:48 +0200 [thread overview]
Message-ID: <cc3e292006cd3c2754e650a5691e3deed4dfaa3a.1587742492.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.d1e741d37e43e1ba2d2ecd93fc81d42a6df99d14.1587742492.git-series.maxime@cerno.tech>
The pllb_arm clock is defined as a fixed factor clock with the pllb
clock as a parent. However, all its configuration is entirely static,
and thus we don't really need to call clk_hw_register_fixed_factor() but
can simply call clk_hw_register() with a static clk_fixed_factor
structure.
