Subject: [RFC 2/4] clk: Add clk_gate_ro_ops for read-only gate clocks
Date: Wed, 21 Oct 2020 20:36:53 +0300 [thread overview]
Message-ID: <1603301815-24670-3-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1603301815-24670-1-git-send-email-abel.vesa@nxp.com>
The clocks that can be changed from outside of the clock common framework
scope (for example, EL3) need to have only the .is_enabled gate op.
