I would like to make this this is okay with you as an approach on how to solve this. This should likely go through Tejun's tree to make sure the SATA controller and PHY changes are bundled together. Thanks! Changes in v2: - avoid introducing an unnecessary port_recovery callback and instead override read_id directly Florian Fainelli (2): phy: brcm-sata: Implement calibrate callback ata: ahci_brcm: Recover from failures to identify devices drivers/ata/ahci_brcm.c | 95 +++++++++++++++++++++++++++++++++--- drivers/phy/broadcom/phy-brcm-sata.c | 32 ++++++++++++ 2 files changed, 119 insertions(+), 8 deletions(-) -- 2.7.4
