Subject: [PATCH v2 3/7] ARM: davinci: da8xx: creation of gpio platform device
Date: Fri, 14 Jun 2013 15:05:28 +0530	[thread overview]
Message-ID: <1371202532-14628-4-git-send-email-avinashphilip@ti.com> (raw)
In-Reply-To: <1371202532-14628-1-git-send-email-avinashphilip@ti.com>

From: KV Sujith <sujithkv@ti.com>

gpio controller resource information being associated with
davinci_soc_info structure and not created any device. Hence davinci
gpio didn't fall under proper device model. This patch creates gpio
davinci as a platform device for da8xx platforms.

- Add Memory and IRQ resources for da8xx
- Register GPIO platform driver for da8xx.
- Add da8xx_register_gpio API to create platform device for da8xx
  platforms.
