From 1d4605e0aff9ffe5163b84ccefaa8c6c2387504d Mon Sep 17 00:00:00 2001 From: Ajay Gupta Date: Sun, 15 Dec 2019 22:14:52 -0800 Subject: [PATCH] net: stmmac: dwc-qos: avoid clk and reset for acpi device There are no clocks, resets or gpios referenced by Tegra ACPI device so don't access clocks, resets or gpios interface with ACPI device. Clocks, resets and GPIOs for ACPI devices will be handled via ACPI interface. Signed-off-by: Ajay Gupta Signed-off-by: David S.
