[PATCH V3 0/9] pm80xx updates

[Viswas G]

This patch set include some bug fixes and enhancement for pm80xx driver.

Changes from V2:
	- Corrected date.

Changes from V1:
        - sas_identify_frame_local structure moved to pm80xx_hwi.h
        - sata abort handling patch split to four patches.
                - tag allocation for phy control request.
                - cleanup in pm8001_abort_task function.
                - modified port reset timer value for PM8006 card
                - corrected SATA abort handling sequence.


Viswas G (9):
  pm80xx : redefine sas_identify_frame structure
  pm80xx : ILA and inactive firmware version through sysfs
  pm80xx : Different SAS addresses for phys.
  pm80xx : tag allocation for phy control request.
  pm80xx : cleanup in pm8001_abort_task function.
  pm80xx : modified port reset timer value for PM8006 card

[PATCH V3 1/9] pm80xx : redefine sas_identify_frame structure

[Viswas G]

sas_identify structure defined by pm80xx doesn't have CRC field.
So added a new sas_identify structure without CRC.

v2:
        - Since the structure changes is applicable for only pm80xx,
          sas_identify_frame_local structure moved to pm80xx_hwi.h.

[PATCH V3 7/9] pm80xx : corrected SATA abort handling sequence.

[Viswas G]

Modified SATA abort handling with following steps:
1) Set device state as recovery.
2) Send phy reset.
3) Wait for reset completion.
4) After successful reset, abort all IO's to the device.
5) After aborting all IO's to device, set device state as operational.

[PATCH V3 8/9] pm80xx : panic on ncq error cleaning up the read log.

[Viswas G]

when there's an error in 'ncq mode' the host has to read the ncq
error log (10h) to clear the error state. however, the ccb that
is setup for doing this doesn't setup the ccb so that the
previous state is cleared. if the ccb was previously used for an IO
n_elems is set and pm8001_ccb_task_free() treats this as the signal
to go free a scatter-gather list (that's already been free-ed).
