2018-08-22ata: add an extra argument to ahci_platform_get_resources()Kunihiko Hayashi1-1/+1
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.

2016-06-15ata: fix return value check in ahci_seattle_get_port_info()Wei Yongjun1-1/+1
In case of error, the function devm_kzalloc() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

2016-04-13ata: add AMD Seattle platform driverBrijesh Singh1-0/+210
AMD Seattle SATA controller mostly conforms to AHCI interface with some special register to control SGPIO interface. In the case of an AHCI controller, the SGPIO feature is ideally implemented using the "Enclosure Management" register of the AHCI controller, but those registeres are not implemented in the Seattle SoC. Instead SoC (Rev B0 onwards) provides a 32-bit SGPIO control register which should be programmed to control the activity, locate and fault LEDs. The driver is based on ahci_platform driver.
