From d9c01c530cc5e3b6d5bdfeae12c3d0f33fae7498 Mon Sep 17 00:00:00 2001 From: Lucas Tanure Date: Fri, 21 Jan 2022 17:24:31 +0000 Subject: [PATCH] ACPI / scan: Create platform device for CS35L41 The ACPI device with CSC3551 or CLSA0100 are sound cards with multiple instances of CS35L41 connected by I2C or SPI to the main CPU. We add an ID to the ignore_serial_bus_ids list to enumerate all I2C or SPI devices correctly. The same IDs are also added into serial-multi-instantiate so that the driver can correctly enumerate the ACPI.
