From aa56a7ffc0fb9ad5f754af79ee91ebe9ec96f28d Mon Sep 17 00:00:00 2001 From: Jonathan Lemon Date: Thu, 19 May 2022 14:21:48 -0700 Subject: ptp: ocp: parameterize input/output sma selectors Group the sma input/output tables together and select the correct group from the bp information. This allows adding new groups with different sma mappings.
