Subject: [PATCH v2 0/2] ata: ahci_brcm: Recover from failures to identify devices

Hi Tejun, Kishon,

This patch series implement a recovery mechanism to work around a HW bug
on Broadcom AHCI SATA controller subject to noise triggering a failure to
identify hard drives.

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
