ata: ahci_platform: fix owner module reference mismatch for scsi host

2015-01-28T23:45:23Z

The owner module reference of the ahci platform's scsi_host is initialized to libahci_platform's one, because these drivers use a scsi_host_template defined in libahci_platform. So these drivers can be unloaded even if the scsi device is being accessed. This fixes it by pushing the scsi_host_template from libahci_platform to all leaf drivers. The scsi_host_template is passed through a new argument of ahci_platform_init_host(). Signed-off-by: Akinobu Mita Signed-off-by: Tejun Heo Cc: Hans de Goede Cc: Christoph Hellwig Cc: "James E.J.

ata: libahci: Allow using multiple regulators

2015-01-19T14:53:26Z

The current implementation of the libahci allows using multiple PHYs but not multiple regulators. This patch adds the support of multiple regulators. Until now it was mandatory to have a PHY under a subnode, now a port subnode can contain either a regulator or a PHY (or both). In order to be able to asociate a port with a regulator the port are now a platform device in the device tree case. There was only one driver which used directly the regulator field of the ahci_host_priv structure. To preserve the bisectability the change in the ahci_imx driver was done in the same patch.

ata: remove deprecated struct ahci_platform_data

2014-08-16T12:35:34Z

The last user of the deprecated struct ahci_platform_data has been cleaned up recently (SPEAr1340 got a proper PHY driver). Signed-off-by: Bartlomiej Zolnierkiewicz Acked-by: Hans de Goede Signed-off-by: Tejun Heo

ata: libahci_platform: move port_map parameters into the AHCI structure

2014-07-30T19:39:46Z

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.

libahci_platform: add host_flags parameter in ahci_platform_init_host()

2014-05-14T17:07:10Z

Add a dynamic host_flags argument to make ahci_platform_init_host more flexible, then remove the AHCI_HFLAGS(...) argument from some driver's ata_port_info, and pass that in as the new argument. Cc: Hans de Geode Reviewed-by: Hans de Goede Signed-off-by: Kefeng Wang Signed-off-by: Tejun Heo

ahci_platform: Drop unused ahci_platform_data members

2014-02-22T22:13:01Z

These members are not used anywhere, and in the future we want ahci_platform_data to go away entirely so there is no reason to keep these around. Signed-off-by: Hans de Goede Signed-off-by: Tejun Heo

ahci-platform: "Library-ise" suspend / resume functionality

2014-02-22T20:35:42Z

Split suspend / resume code into host suspend / resume functionality and resource enable / disabling phases, and export the new suspend_ / resume_host functions. tj: Minor comment formatting updates. Signed-off-by: Hans de Goede Signed-off-by: Tejun Heo

ahci-platform: "Library-ise" ahci_probe functionality

2014-02-22T20:35:42Z

ahci_probe consists of 3 steps: 1) Get resources (get mmio, clks, regulator) 2) Enable resources, handled by ahci_platform_enable_resouces 3) The more or less standard ahci-host controller init sequence This commit refactors step 1 and 3 into separate functions, so the platform drivers for AHCI implementations which need a specific order in step 2, and / or need to do some custom register poking at some time, can re-use ahci-platform.c code without needing to copy and paste it. Note that ahci_platform_init_host's prototype takes the 3 non function members of ahci_platform_data as arguments, the idea is that drivers using the new exported utility functions will not use ahci_platform_data at all, and hopefully in the future ahci_platform_data can go away entirely. tj: Minor comment formatting updates.
