Subject: [PATCH V6 3/7] device property: Introduce a common API to fetch device match data
Date: Tue, 5 Dec 2017 12:04:48 -0500 [thread overview]
Message-ID: <1512493493-6464-4-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1512493493-6464-1-git-send-email-okaya@codeaurora.org>
There is an OF/ACPI function to obtain the driver data. We want to hide
OF/ACPI details from the device drivers and abstract following the device
family of functions.
