Subject: [PATCH v5 2/7] gpio: pca953x: add more register definitions for pcal953x
Date: Sat, 28 Apr 2018 18:31:32 +0200	[thread overview]
Message-ID: <79da0e04213915b797222027bbeaebf513387e62.1524933096.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1524933096.git.hns@goldelico.com>
In-Reply-To: <cover.1524933096.git.hns@goldelico.com>

PCAL chips ("L" seems to stand for "latched") have additional
registers starting at address 0x40 to control the latches,
interrupt mask, pull-up and pull down etc.
