From 8a90efd15ef6472809374aea963927dcba2bfc03 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 28 Jun 2019 10:46:14 +0900 Subject: [PATCH] ASoC: vc4: vc4_htmi: consider CPU-Platform possibility commit 6c6de1c9e2bf2 ("ASoC: vc4: vc4_hdmi: don't select unnecessary Platform") Current ALSA SoC avoid to add duplicate component to rtd, and this driver was selecting CPU component as Platform component. Thus, above patch removed Platform settings from this driver, because it assumed these are same component. But, some CPU driver is using generic DMAEngine, in such case, both CPU component and Platform component will have same of_node/name. In other words, there are some components which are different but have same of_node/name. In such case, Card driver definitely need to select Platform even though it is same as CPU. It is depends on CPU driver, but is difficult to know it from Card driver. This patch reverts above patch.
