From fc566dab45f9eab9b07c971daedd0843e688e777 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Sun, 28 Mar 2021 12:31:08 -0500 Subject: [PATCH] net: ipa: switch to version based configuration Rename the SDM845 configuration data file so that its name is derived from its IPA version. I am not aware of any special IPA behavior or handling that would be based on a specific SoC (as opposed to a specific version of the IPA it contains). Update a few other references to the code that talk about the SDM845 rather than just IPA v3.5.1. Signed-off-by: Alex Elder Signed-off-by: David S.
