From e1a84d56fcb92d4551692cbec4bada1cec00e620 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Thu, 24 Oct 2019 09:52:25 +0300 Subject: habanalabs: use registers name defines for ETR block We have a single ETR block in the SOC, so use explicit register name defines for initializing this block. This makes it more readable and maintainable.
