Subject: [PATCH 12/13] clk: samsung: acpm: drop determine_rate op and use CLK_ROUNDING_FW_MANAGED flag
Date: Thu, 26 Feb 2026 13:16:56 -0500 [thread overview]
Message-ID: <20260226-clk-det-rate-fw-managed-v1-12-4421dd2f6dc6@redhat.com> (raw)
In-Reply-To: <20260226-clk-det-rate-fw-managed-v1-0-4421dd2f6dc6@redhat.com>
This clk driver has a noop determine_rate clk op. Drop this empty
function, and enable the CLK_ROUNDING_FW_MANAGED flag.
