X-Git-Tag: v5.15~2056^2~76
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8f87b6271ec85c09af6406665324c74bb79e3216;p=platform%2Fkernel%2Flinux-starfive.git

crypto: qat - remove global CSRs helpers

Include the offset of GLOBAL_CSR directly into the enum hal_global_csr
and remove the macros SET_GLB_CSR/GET_GLB_CSR to simplify the global CSR
access.
