#1661838 — [PATCH v6 0/2] Altera CvP driver

Add FPGA manager support for PCIe CvP on Cyclone-V/Stratix-V/Arria-V
and Arria-10 FPGAs.

Changes in v6:
 - rebase to apply on top of queued fpga manager patches
 - add comment for new fpga info flag in patch 1/2
 - resubmit FPGA_MGR_COMPRESSED_BITSTREAM patch together
   with driver patch (it was a single patch before)
 - minor style changes (variable names, return value checking, etc.)
 - do {} while() loop style changes
 - capitalize acronyms in comments
 - simplify code by using pci_name() string for FPGA manager name
 - numclks init style changes
 - %s/VSEC_/VSE_/g

#1661841 — [PATCH v6 1/2] fpga: Add flag to indicate bitstream needs decompression

Add a flag that is passed to the write_init() callback, indicating
that the bitstream is compressed.

The low-level driver will deal with the flag, or return an error,
if compressed bitstreams are not supported.

this series has been reviewed, could you please queue it for 4.13,
together with altera-ps-spi driver series?

Thanks,
Anatolij
