From ec4a95409d5c28962e0097e8291aa7048f8b262a Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Thu, 22 Nov 2018 18:23:23 +0800 Subject: [PATCH] arm64: dts: allwinner: a64: add nodes necessary for analog sound support Add nodes for i2s, digital and analog parts of audiocodec on A64. The routing paths listed are entries connecting the digital and analog side of the audio codec together. Due to how device tree works, these must be copied over to each board device tree, in addition to any board level routes. The oversampling rate is set to 128, so that when playing back 192 kHz audio samples, the MCLK runs at the same rate as the module clock, at 24.576 MHz. The user manual suggests using different oversampling rates for different sample rates, but that's not possible without a platform-specific machine driver.
