Subject: [PATCH v2 2/4] pinctrl: qcom: Remove irq_disable callback from msmgpio irqchip
Date: Sat, 23 May 2020 22:41:11 +0530
Message-ID: <1590253873-11556-3-git-send-email-mkshah@codeaurora.org> (raw)
In-Reply-To: <1590253873-11556-1-git-send-email-mkshah@codeaurora.org>

The gpio can be marked for wakeup and drivers can invoke disable_irq()
during suspend, in such cases unlazy approach will also disable at HW
and such gpios will not wakeup device from suspend to RAM.

Remove irq_disable callback to allow gpio interrupts to lazy disabled.
The gpio interrupts will get disabled during irq_mask callback.
