| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a device is disabled after error recovery it doesn't make any sense to generate an ATA sense, but we should rather return a generic sense code indicating the device is gone.

| * | | dmaengine: dw: rename masters to reflect actual topologyAndy Shevchenko2016-04-13

The patch changes the master names to reflect which one is related to which independently on the transfer direction. The outcome of the change is that the memory data width is now always limited by a data width of the master which is dedicated to communicate to memory. The patch will not break anything since all current users have the same data width for all masters. Though it would be nice to revisit avr32 platforms to check what is the actual hardware topology in use there. It seems that it has one bus and two masters on it as stated by Table 8-2, that's why everything works independently on the master in use. The purpose of the sequential patch is to fix the driver for configuration of more than one bus. The change is done in the assumption that src_master and dst_master are reflecting a connection to the memory and peripheral correspondently on avr32 and otherwise on the rest.

In the case of an AHCI controller, the SGPIO feature is ideally implemented using the "Enclosure Management" register of the AHCI controller, but those registeres are not implemented in the Seattle SoC. Instead SoC (Rev B0 onwards) provides a 32-bit SGPIO control register which should be programmed to control the activity, locate and fault LEDs. The driver is based on ahci_platform driver.

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.

The total 15s is too short for some drives to complete spinup (e.g. drives with a large indirection table stored on media), resulting in ata_dev_read_id to fail twice on the execution of SETFEATURES_SPINUP. For this feature, allow a larger default timeout of 30 seconds. However, in the same spirit as with the timeout of other feature subcommands, do not ignore ata_probe_timeout if it is set).

| * | sata_via: Apply WD workaround only when needed on VT6421Ondrej Zary2016-02-25

And it has a bug - it's not applied after resume. Apply the workaround only if the error really appears (SErr == 0x1000500). This allows unaffected drives to run at full speed (provided that no affected drive is connected to the controller). Also make sure the workaround is re-applied on resume. Tested on VT6421. As SCR registers access is known to cause problems on VT6420 (and I don't have it to test), keep the workaround applied always on VT6420.

| * | ahci: Add runtime PM support for the host controllerMika Westerberg2016-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds runtime PM support for the AHCI host controller driver so that the host controller is powered down when all SATA ports are runtime suspended. Powering down the AHCI host controller can reduce power consumption and possibly allow the CPU to enter lower power idle states (S0ix) during runtime. Runtime PM is blocked by default and needs to be unblocked from userspace as needed (via power/* sysfs nodes).

| * | ahci: Add functions to manage runtime PM of AHCI portsMika Westerberg2016-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new functions ahci_rpm_get_port()/ahci_rpm_put_port() that change runtime PM status of AHCI ports. Depending if the AHCI host has runtime PM enabled or disabled calling these may trigger runtime suspend/resume of the host controller. We also call these functions in appropriate places to make sure host controller registers are available before using them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to add support for runtime PM to the ahci driver we first need to convert the driver to use modern non-legacy system suspend hooks. There should be no functional changes. tj: Updated .driver.pm init for older compilers as suggested by Andy and Chrsitoph.
