To: Tejun Heo, Hans de Goede, Maxime Ripard, linux-ide, linux-kernel
Cc: wangkefeng.wang, kefeng.wang
changes in v4:
1) add a dynamic host_flags parameter in ahci_platform_init_host
to make it more flexible, modify some driver to use new
way to pass host flags, suggested by Hans
changes in v3:
1) move NO_FBS chunk after YES_FBS, Tejun's suggestion
2) use ata_port_info pointer to avoid struct ata_port_info
on the stack twice
changes in v2:
1) make code more concise according to Hans's advice
Kefeng Wang (3):
ata: ahci: append new hflag AHCI_HFLAG_NO_FBS
libahci_platform: add host_flags parameter in
ahci_platform_init_host()
ahci: add support for Hisilicon sata
