From d1478aea649e739a0a0e4890cd8b049ae5d08c13 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 29 Jun 2023 18:01:32 +0200 Subject: memory: tegra: Add dummy implementation on Tegra194 With the introduction of commit 9365bf006f53 ("PCI: tegra194: Add interconnect support in Tegra234"), the PCI driver on Tegra194 and later requires an interconnect provider. However, a provider is currently only exposed on Tegra234 and this causes PCI on Tegra194 to defer probe indefinitely. Fix this by adding a dummy implementation on Tegra194. This allows nodes to be provided to interconnect consumers, but doesn't do any bandwidth accounting or frequency scaling.
