Subject: [PATCH 3/8] ARM: dts: bcm6846: Add GPIO blocks
Date: Fri, 11 Oct 2024 00:07:01 +0200 [thread overview]
Message-ID: <20241011-genexis-xg6846b-base-v1-3-f04d6f6f93ce@linaro.org> (raw)
In-Reply-To: <20241011-genexis-xg6846b-base-v1-0-f04d6f6f93ce@linaro.org>
The BCM6846 has the same simplistic GPIOs as some other
Broadcom SoCs: plain memory-mapped registers with up to
8 blocks of 32 GPIOs each totalling 256 GPIOs.
Users of the SoC can selectively enable the GPIO blocks
actually used with a certain design.
