Subject: [RESEND PATCH v1 8/9] spmi: pmic-arb: make interrupt support optional
Date: Fri, 17 Sep 2021 14:33:03 +0800 [thread overview]
Message-ID: <1631860384-26608-9-git-send-email-quic_fenglinw@quicinc.com> (raw)
In-Reply-To: <1631860384-26608-1-git-send-email-quic_fenglinw@quicinc.com>
From: David Collins <collinsd@codeaurora.org>
Make the support of PMIC peripheral interrupts optional for
spmi-pmic-arb devices. This is useful in situations where
SPMI address mapping is required without the need for IRQ
support.
