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. V4 Changes Rename delta_credit to space Simplify wait for credit do-while loop. Change from udelay() to usleep_range() Use min() to find length to send Remove NULL initialization from private structure Use #define for Version1 offsets Change current_credit_byte to u32 sent_packets. Changes to Kconfig title and description to support Stratix10.
