Subject: [PATCH 1/6] arm64: dts: imx8mm-var-som: fix missing PMIC's interrupt line pull-up
Date: Sun, 27 Sep 2020 18:59:42 +0200	[thread overview]
Message-ID: <20200927165947.7317-1-krzk@kernel.org> (raw)

The PMIC's interrupt is level low and should be pulled up.  The PMIC's
device node had pinctrl-0 property but it lacked pinctrl-names which
is required to apply the pin configuration.  The actual problem in DTS
was pointed out by Felix Radensky from Variscite.

Reported-by: Felix Radensky <felix.r@variscite.com>
Fixes: 5f67317bd967 ("arm64: dts: imx8mm: correct interrupt flags")
