2012-05-17isci: Implement waiting for suspend in the abort path.Jeff Skirvin
In order to prevent a device from receiving an I/O request while still in an RNC suspending or resuming state (and therefore failing that I/O back to libsas with a reset required status) wait for the RNC state change before proceding in the abort path.

2012-05-17isci: Make sure all TCs are terminated and cleaned in LUN reset.Jeff Skirvin
In the libsas error path, SATA disks require extra handling in libata to recover operation. However, libsas expects to be able to immediately recover all outstanding I/O once the error handler escalation stops. This patch fixes the condition where the libata error handler is scheduled for operation but libsas has already deleted the outstanding sas_tasks.

2012-05-17isci: Manage the LLHANG timer enable/disable per-device.Jeff Skirvin

2012-05-17isci: Save the suspension hint for upcoming suspensions.Jeff Skirvin
In the case of a suspend call while in SCI_RNC_POSTING or INVALIDATING states, the LLHANG detect needed to be saved so the upcoming suspension would enable it correctly. The unused suspend callback parameters were removed. Signed-off-by: Jeff Skirvin <jeffrey.d.skirvin@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2012-05-17isci: Fix the terminated I/O to not call sas_task_abort().Jeff Skirvin
This addresses a regression from the commit "isci: Redesign device suspension, abort, cleanup." in which the sas_task end condition for terminated I/Os was made to call back on sas_task_abort()".

2012-05-17isci: Add suspension cases for RNC INVALIDATING, POSTING states.Jeff Skirvin
The RNC can be any of the states in the loop from suspended to ready when the API "suspend" or "resume" are called.

2012-05-17isci: Redesign device suspension, abort, cleanup.Jeff Skirvin
This commit changes the means by which outstanding I/Os are handled for cleanup. The likelihood is that this commit will be broken into smaller pieces, however that will be a later revision. Among the changes: - All completion structures have been removed from the tmf and abort paths. - Now using one completed I/O list, with the I/O completed in host bit being used to select error or normal callback paths.

2012-05-17isci: Handle all suspending TC completionsJeff Skirvin
Add comprehensive decode for all TC completions that generate RNC suspensions. Note that this commit also removes unconditional resumptions of ATAPI devices when in the SCI_STP_DEV_ATAPI_ERROR state, and STP devices when in the SCI_STP_DEV_IDLE state. This is because the SCI_STP_DEV_IDLE and SCI_STP_DEV_ATAPI state entry functions manage the RNC resumption.

2012-05-17isci: Manage the link layer hang detect timer for RNC suspensions.Jeff Skirvin
For STP devices under certain protocol conditions, an RNC will not suspend until the current transfer state is broken with a SYNC/ESC sequence from the SCU. The SYNC/ESC driven by expiration of the SCU link layer hang detect timer, which has too small a dynamic range to support slow SATA devices, so normally it is disabled. This change enables the timer with the minimum period at the point when the suspension is requested. Note that there is potential collateral damage to other open connections to slow SATA devices on the same port, since there is no alternative but to enable the LLHANG timer on every phy in the port for the current suspension request - there is no way to tell on which phy the RNC in question is currently active.

2012-05-17isci: fix oem parameter validation on single controller skusDan Williams
OEM parameters [1] are parsed from the platform option-rom / efi driver. By default the driver was validating the parameters for the dual-controller case, but in single-controller case only the first set of parameters may be valid. Limit the validation to the number of actual controllers detected otherwise the driver may fail to parse the valid parameters leading to driver-load or runtime failures.

2012-05-17isci: fix interrupt disableDan Williams
There is a (dubious?) lost irq workaround in sci_controller_isr() that effectively nullifies attempts to disable interrupts. Until the workaround can be re-evaluated add some infrastructure to prevent the interrupt handler from inadvertantly re-enabling interrupts. The failure mode was interrupts continuing to run after the driver had been removed and its iomappings torn down.

2012-05-17isci: fix 'link-up' events occur after 'start-complete'Dan Williams
The call to wait_for_start() is meant to ensure that all links have been given a chance to come up before letting the kernel proceed with probing. However, the implementation is not correctly syncing with the port configuration agent. In the MPC case the ports are hard-coded, in the APC case we need to wait for the port-configuration to form ports from the started phys. Towards that end increase the timeout for the APC agent to form ports, and delay start complete until all phys are out of link-training.

2012-05-17isci: refactor initialization for S3/S4Dan Williams
Based on an original implementation by Ed Nadolski and Artur Wojcik In preparation for S3/S4 support refactor initialization so that driver-load and resume-from-suspend can share the common init path of isci_host_init(). Organize the initialization into objects that are self-contained to the driver (initialized by isci_host_init) versus those that have some upward registration (initialized at allocation time asd_sas_phy, asd_sas_port, dma allocations). The largest change is moving the the validation of the oem and module parameters from isci_host_init() to isci_host_alloc(). The S3/S4 approach being taken is that libsas will be tasked with remembering the state of the domain and the lldd is free to be forgetful. In the case of isci we'll just re-init using a subset of the normal driver load path.

However MCT is not operating properly on early revision of EXYNOS4 SoCs. All UniversalC210 boards are based on it, so that commit broke support for it.
