Subject: [PATCH] gpio: pca953x: Add support for the NXP PCAL9554B/C
Date: Mon, 28 Sep 2020 09:33:17 +0200 [thread overview]
Message-ID: <20200928073317.7240-1-mike.looijmans@topic.nl> (raw)
The NXP PCAL9554B is a variant of the PCA953x GPIO expander,
with 8 GPIOs, latched interrupts and some advanced configuration
options. The "C" version only differs in I2C address.
Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl>
