Subject: [PATCH v2 1/2] dt-bindings: at24: Add address-width property
Date: Tue, 26 Jun 2018 14:22:07 +0800 [thread overview]
Message-ID: <1529994128-26770-2-git-send-email-alanx.chiang@intel.com> (raw)
In-Reply-To: <1529994128-26770-1-git-send-email-alanx.chiang@intel.com>
From: "alanx.chiang" <alanx.chiang@intel.com>
The AT24 series chips use 8-bit address by default. If some
chips would like to support more than 8 bits, should add the compatible
field for specfic chips in the driver.
Provide a flexible way to determine the addressing bits through
address-width in this patch.

since v1:
-- Remove the address-width field in the example.
