Subject: [PATCH v5 2/3] arm64: dts: ti: k3-j7200-common-proc-board: Disable unused gpio modules
Date: Wed, 10 Mar 2021 21:49:22 +0530 [thread overview]
Message-ID: <20210310161924.22256-3-a-govindraju@ti.com> (raw)
In-Reply-To: <20210310161924.22256-1-a-govindraju@ti.com>
From: Faiz Abbas <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.
