Subject: [PATCH v4 08/13] ata: ahci_sunxi: add support for r40
Date:   Thu, 30 Aug 2018 21:01:15 +0200
Message-Id: <20180830190120.722-9-clabbe.montjoie@gmail.com>
In-Reply-To: <20180830190120.722-1-clabbe.montjoie@gmail.com>
References: <20180830190120.722-1-clabbe.montjoie@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch add the r40 compatible to the ahci_sunxi's supported list of
compatible.

Since R40 need ahci_platform to handle the reset controller, we also add
the new AHCI_PLATFORM_GET_RESETS flag for ahci_platform_get_resources().
This has no consequence for older platform (a10, a20) since the reset is
optional.
