Subject: [PATCH v4 1/7] pinctrl: qcom: Add msmgpio irqchip flags
Date: Mon, 10 Aug 2020 16:50:54 +0530	[thread overview]
Message-ID: <1597058460-16211-2-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1597058460-16211-1-git-send-email-mkshah@codeaurora.org>

Add irqchip specific flags for msmgpio irqchip to mask non wakeirqs
during suspend and mask before setting irq type.

Masking before changing type should make sure any spurious interrupt
is not detected during this operation.

Fixes: e35a6ae0eb3a ("pinctrl/msm: Setup GPIO chip in hierarchy")
Acked-by: Linus Walleij <linus.walleij@linaro.org>
