Subject: [PATCH v3 00/15] clk: introduce clk_determine_rate_noop() and update drivers to use it
Date: Tue, 05 May 2026 20:48:56 -0400 [thread overview]
Message-ID: <20260505-clk-determine-rate-noop-v3-0-f3f829fbacdf@redhat.com> (raw)
There are some clocks where the determine_rate clk op is just an empty
function that returns 0. This can be either because the rounding is
managed by the firmware/hardware, or the clock is capable of any rate.
Let's add a new new shared function to clk.c named
clk_determine_rate_noop(), and update all of the drivers that have an
empty determine_rate() ops to use this new shared function.
The first patch in this series also includes a minor cleanup to
drivers/clk/imx/clk-scu.c. I included it as the first patch so it
doesn't get buried in the middle of this series. I change this same
driver later in the series to use clk_determine_rate_noop().
Changes since v2:
https://lore.kernel.org/all/20260309-clk-det-rate-fw-managed-v2-0-c48ef5a3100a@redhat.com/
- Dropped the NOOP flag and just use a dedicated noop function.
Merge Strategy
--------------
All of this needs to be directly merged by Stephen as one series into
his tree. Subsystem maintainers: please leave a Reviewed-by or Acked-by
for Stephen. To reduce the noise, I am only CCing people on their
respective drivers.
Since there's only 3 drivers outside of drivers/clk that need to be
updated, I included them in this same series for completeness. These
should go through Stephen's tree as well.
