Subject: [PATCH V1 7/9] spmi: pmic-arb: support updating interrupt type flags
Date: Fri, 20 Aug 2021 12:58:02 +0800	[thread overview]
Message-ID: <1629435488-10228-8-git-send-email-quic_fenglinw@quicinc.com> (raw)
In-Reply-To: <1629435488-10228-1-git-send-email-quic_fenglinw@quicinc.com>

From: Yimin Peng <yiminp@codeaurora.org>

Have the qpnpint_irq_set_type function clear unwanted high/low
trigger bits when updating the interrupt flags.
