Subject: [PATCH v4 2/7] gpio: pca953x: add more register definitions for pcal953x
Date: Thu, 26 Apr 2018 19:34:57 +0200 [thread overview]
Message-ID: <a4d21a45bc8258ca4adc982e312cec01a69cfb69.1524764101.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1524764101.git.hns@goldelico.com>
In-Reply-To: <cover.1524764101.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.
