Subject: [PATCH 01/22] fjes: Introduce FUJITSU Extended Socket Network Device driver
Date: Thu, 18 Jun 2015 09:49:26 +0900 [thread overview]
Message-ID: <1434588587-25655-1-git-send-email-izumi.taku@jp.fujitsu.com> (raw)
In-Reply-To: <1434588359-25589-1-git-send-email-izumi.taku@jp.fujitsu.com>
This patch adds the basic code of FUJITSU Extended Socket
Network Device driver.
When "PNP0C02" is found in ACPI DSDT, it evaluates "_STR"
to check if "PNP0C02" is for Extended Socket device driver
and retrieves ACPI resource information. Then creates
platform_device.
