Subject: [PATCH 3/3] arm64: dts: ti: k3-j7200-common-proc-board: Disable unused gpio modules
Date: Tue, 3 Nov 2020 00:41:20 +0530	[thread overview]
Message-ID: <20201102191120.20380-4-faiz_abbas@ti.com> (raw)
In-Reply-To: <20201102191120.20380-1-faiz_abbas@ti.com>

There are 6 gpio instances inside SoC with 2 groups as show below:
	Group one: wkup_gpio0, wkup_gpio1
	Group two: main_gpio0, main_gpio2, main_gpio4, main_gpio6

Only one instance from each group can be used at a time. So use main_gpio0
and wkup_gpio0 in current linux context and disable the rest of the nodes.
