From 24a41a38dd2df065ee942221c2fae5e314770865 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Wed, 20 Jan 2021 03:31:52 +0300 Subject: ASoC: tegra: ahub: Add missing resets AHUB driver misses D_AUDIO and APBIF resets. CPU hangs on trying to access hardware if resets aren't de-asserted. This problem is currently masked by the tegra-clk driver which implicitly de-asserts the resets when the corresponding clocks are enabled. Soon the implicit de-assertion will be gone from the tegra-clk driver, thus we need to fix the AHUB driver. Add the missing resets to the driver.
