ata: ahci-platform: Add ports-implemented DT bindings.

2016-05-11T09:21:21Z

commit 17dcc37e3e847bc0e67a5b1ec52471fcc6c18682 upstream. On some SOCs PORTS_IMPL register value is never programmed by the firmware and left at zero value. Which means that no sata ports are available for software. AHCI driver used to cope up with this by fabricating the port_map if the PORTS_IMPL register is read zero, but recent patch broke this workaround as zero value was valid for NVMe disks. This patch adds ports-implemented DT bindings as workaround for this issue in a way that DT can can override the PORTS_IMPL register in cases where the firmware did not program it already.

Revert "ahci: added support for Freescale AHCI sata"

2015-09-08T16:30:06Z

This reverts commit 5163fb62541e ("ahci: added support for Freescale AHCI sata") The reverted patch added Freescale QorIQ AHCI sata support to ahci_platform driver though, but it left SoC specific settings to uboot. It leads to QorIQ sata heavily depending on uboot. In order to removing the dependency we first revert the old patch and then will add a new driver for QorIQ SATA. Since there are no LS* platforms that have been upstreamed, So the revert would not break anything exists. Signed-off-by: Tang Yuantian Reviewed-by: Hans de Goede Signed-off-by: Tejun Heo

ahci: st: Update the ahci_st DT documentation

2015-04-01T16:07:02Z

As part of testing ahci_st driver working on stih407 I noticed several things wrong in the DT documentation: - 1) Compatible string doesn't match the driver code 2) pwr-rst reset isn't documented (but exists in the driver) 3) some whitespace issues (spaces not tabs) Also add in a stih407 family example into the doc.

ahci: st: Update the DT example for how to obtain the PHY.

2015-04-01T16:05:41Z

The example is wrong in that the phys property should take a phandle to the phy port. Also with the changing over to generic PHY type constants we also update that as well. Signed-off-by: Peter Griffin Acked-by: Rob Herring Acked-by: Lee Jones Signed-off-by: Tejun Heo
