You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From 7894a7e7ea3de6c1fd5b2b43f3a73106c94ef584 Mon Sep 17 00:00:00 2001 From: Vijendar Mukunda Date: Mon, 12 Nov 2018 11:04:54 +0530 Subject: [PATCH] ASoC: amd: create ACP3x PCM platform device ACP 3x IP has I2S controller device as one of IP blocks. Create a platform device for it, so that the PCM platform driver can be bound to this device. Pass PCI resources like MMIO, irq to the platform device.
