Subject: [PATCH v1 1/3] ARM: dts: meson8: add the xtal_32k_out pin
Date: Tue, 21 Mar 2023 18:12:11 +0100 [thread overview]
Message-ID: <20230321171213.2808460-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20230321171213.2808460-1-martin.blumenstingl@googlemail.com>
GPIOX_10 can generate a 32768Hz signal when enabling the "xtal_32k_out"
group with the xtal function. This is typically used as LPO clock for
the SDIO wifi chips.
