[PATCHv3 0/3] fpga: altera-cvp: Add Stratix10 Support

[thor . thayer]

From: Thor Thayer <thor.thayer@xxxxxxxxxxxxxxx>

Newer versions (V2) of Altera/Intel FPGAs CvP have different PCI
Vendor Specific Capability offsets than the older (V1) Altera/FPGAs.

Most of the CvP registers and their bitfields remain the same
between both the older parts and the newer parts.

This patchset implements changes to discover the Vendor Specific
Capability offset and then add Stratix10 CvP support.

V2 Changes:
  Remove inline designator from abstraction functions.
  Reverse Christmas Tree format for local variables
  Remove redundant mask from credit calculation
  Add commment for the delay(1) function in wait_for_credit()

V3 Changes
  Return int instead of void for abstraction functions
  Check the return code from read in altera_cvp_chk_error()
  Move reset of current_credit_byte to clear_state().
  Check return codes of read/writes in added functions.

  fpga: altera-cvp: Add Stratix10 (V2) Support
