From 725c7b570fda4207e465ff8856c2c12c2645a685 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Antoine=20T=C3=A9nart?= Date: Wed, 30 Jul 2014 20:13:56 +0200 Subject: ata: libahci_platform: move port_map parameters into the AHCI structure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch moves force_port_map and mask_port_map into the ahci_host_priv structure. This allows to modify them into the AHCI framework. This is needed by the new dt bindings representing ports as the port_map mask is computed automatically. Parameters modifying force_port_map, mask_port_map and flags have been removed from the ahci_platform_init_host() function, and inputs in the ahci_host_priv structure are now directly filed.
