libata: mask swap internal and hardware tag

2018-09-20T14:30:55Z

hen we're comparing the hardware completion mask passed in from the driver with the internal tag pending mask, we need to account for the fact that the internal tag is different from the hardware tag. If not, then we can end up either prematurely completing the internal tag (since it's not set in the hw mask), or simply flag an error: ata2: illegal qc_active transition (100000000->00000001) If the internal tag is set, then swap that with the hardware tag in this case before comparing with what the hardware reports.

ata: ftide010: Add a quirk for SQ201

2018-08-27T20:25:54Z

The DMA is broken on this specific device for some unknown reason (probably badly designed or plain broken interface electronics) and will only work with PIO. Other users of the same hardware does not have this problem. Add a specific quirk so that this Gemini device gets DMA turned off. Also fix up some code around passing the port information around in probe while we're at it. Signed-off-by: Linus Walleij Signed-off-by: Jens Axboe

ata: ahci_platform: enable to get and control reset

2018-08-22T15:08:28Z

Unlike SoC-specific driver, generic ahci_platform driver doesn't have any chances to control resets. This adds AHCI_PLATFORM_GET_RESETS to ahci_platform_get_resources() on the generic driver to enable reset control support.

ata: libahci_platform: add reset control support

2018-08-22T15:08:27Z

Add support to get and control a list of resets for the device as optional and shared. These resets must be kept de-asserted until the device is enabled. This is specified as shared because some SoCs like UniPhier series have common reset controls with all ahci controller instances. However, according to Thierry's view, https://www.spinics.net/lists/linux-ide/msg55357.html some hardware-specific drivers already use their own resets, and the common reset make a path to occur double controls of resets. The ahci_platform_get_resources() can get and control the reset only when the second argument includes AHCI_PLATFORM_GET_RESETS bit.

ata: add an extra argument to ahci_platform_get_resources()

2018-08-22T15:08:27Z

Add an extra argument to ahci_platform_get_resources(), that is for the bitmap representing the resource to get in this function. Currently there is no resources to be defined, so all the callers set '0' to the argument.
