Subject: [PATCH 1/3] Input: omap4-keypad - configure interrupt as level
Date: Fri, 28 Feb 2020 09:12:21 -0800 [thread overview]
Message-ID: <20200228171223.11444-2-tony@atomide.com> (raw)
In-Reply-To: <20200228171223.11444-1-tony@atomide.com>
The interrupt should be level high for SoC internal devices.
Otherwise interrupts may not be seen after a wake-up event.
