Subject: [PATCH 2/5] clk: qcom: Allow custom reset ops
Date: Sat, 30 Jul 2022 14:47:41 +0530	[thread overview]
Message-ID: <20220730144713.2.I4b69f984a97535179acd9637426a1331f84f6646@changeid> (raw)
In-Reply-To: <1659172664-10345-1-git-send-email-quic_akhilpo@quicinc.com>

Add support to allow soc specific clk drivers to specify a custom reset
operation. A consumer-driver of the reset framework can call
"reset_control_reset()" api to trigger this.
