ahci: Add PCI ids for Intel Bay Trail, Cherry Trail and Apollo Lake AHCI

2018-02-16T19:06:47+00:00

commit 998008b779e424bd7513c434d0ab9c1268459009 upstream.

Add PCI ids for Intel Bay Trail, Cherry Trail and Apollo Lake AHCI
SATA controllers. This commit is a preparation patch for allowing a
different default sata link powermanagement policy for mobile chipsets.

ahci: Annotate PCI ids for mobile Intel chipsets as such

2018-02-16T19:06:47+00:00

commit ca1b4974bd237f2373b0e980b11957aac3499b56 upstream.

Intel uses different SATA PCI ids for the Desktop and Mobile SKUs of their
chipsets. For older models the comment describing which chipset the PCI id
is for, aksi indicates when we're dealing with a mobile SKU. Extend the
comments for recent chipsets to also indicate mobile SKUs.

The information this commit adds comes from Intel's chipset datasheets.

This commit is a preparation patch for allowing a different default
sata link powermanagement policy for mobile chipsets.

libata: apply MAX_SEC_1024 to all LITEON EP1 series devices

2017-12-19T13:30:38+00:00

LITEON EP1 has the same timeout issues as CX1 series devices.

Revert max_sectors to the value of 1024.

libata: sata_down_spd_limit should return if driver has not recorded sstatus speed

2017-12-04T21:57:03+00:00

During hotplug, it is possible for 6Gbps link speed to be limited all
the way down to 1.5 Gbps which may lead to a slower link speed when
drive is re-connected.

This behavior has been seen on a Intel Lewisburg SATA controller
(8086:a1d2) with HGST HUH728080ALE600 drive where SATA link speed was
limited to 1.5 Gbps and when re-connected the link came up 3.0 Gbps.

This patch was retested on above configuration and showed the
hotplugged link to come back online at max speed (6Gbps). I did not
see the downgrade when testing on Intel C600/X79, but retested patched
linux-4.14-rc5 kernel and didn't see any side effects from this
change. Also, successfully retested hotplug on port multiplier 3Gbps
link.

tj: Minor comment updates.

ahci: mtk: Change driver name to ahci-mtk

2017-12-04T20:35:29+00:00

The driver name "ahci" is already used by the ahci platform driver.
This leads to the following error:
Error: Driver 'ahci' is already registered, aborting...

Change the name to ahci-mtk to fix this.

ahci: qoriq: refine port register configuration

2017-12-04T20:18:08+00:00

These PP2C and PP3C registers control the configuration of the PHY
control OOB timing for the COMINIT/COMWAKE parameters respectively
for sata port. Overwrite default values with calculated ones to get
better OOB timing.
