Subject: [PATCH 2/3] dt-bindings: auxdisplay: Add JHD1313 bindings
Date: Thu, 28 Nov 2019 10:55:07 +0000 [thread overview]
Message-ID: <20191128105508.3916-3-kbingham@kernel.org> (raw)
In-Reply-To: <20191128105508.3916-1-kbingham@kernel.org>
From: Kieran Bingham <kbingham@kernel.org>
The JHD1313 is used in the Grove RGB LCD controller [0] and provides
an I2C interface to control the LCD.
The implementation is based upon the datasheet for the JHD1214 [1], as
this is the only datasheet referenced by the documentation for the Grove
part.

+title: DT bindings for the JHD1313 Character LCD Controller

+description:
+ The JHD1313 Character LCD Controller is used by the widely available Grove
+ LCD RGB Backlight display. This currently supports only 16x2 LCD Modules. The
+ reg property specifies the I2C address of the module, and is expected to be
+ 0x3e.
