Subject: [PATCH v5 1/6] pinctrl: qcom: Set IRQCHIP_SET_TYPE_MASKED and IRQCHIP_MASK_ON_SUSPEND flags
Date: Sat, 22 Aug 2020 21:46:56 +0530	[thread overview]
Message-ID: <1598113021-4149-2-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1598113021-4149-1-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>
