From 3e2db2c2418d5373205f7214ff1ef4e70aafefe1 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 13 Jan 2023 02:04:13 +0000 Subject: arm64: dts: renesas: Add ulcb{-kf} Audio Graph Card2 dtsi ALSA SoC has many types of Generic Audio Card drivers (Simple Audio Card, Audio Graph Card, Audio Graph Card2), and Renesas/Kuninori Morimoto wants to test these. The Generic Audio Card driver had been requested on ALSA SoC. It supports many types of device connection methods, and historically, the requested connection support range of the generic driver has been upgraded. Upgrading the connection support range itself could not be implemented in the generic driver, because we need to keep compatibility with old DTBs. This is one of the reasons why we have many types of Generic Audio Card driver. The ULCB/KF combo is a good board stack to test these. Kuninori has been testing these Generic Audio Card drivers by using his local patches to switching drivers. But from an information sharing point of view, it is a good idea to upstream these, because the DT configuration is complex. Hence this can be a good sample for the user. Hence add an "Audio Graph Card2" DT setting file for ULCB/KF, and switch to use it. You can switch to a different Generic Audio Graph driver by updating ulcb.dtsi / ulcb-kf.dtsi. From a normal user point of view who doesn't need to test the driver, everything should stay as-is, and nothing changes. Note that because this needs "switching driver", and not "adding extra feature", this does not use a Device Tree overlay.
