From 955ac624058f91172b3b8820280556e699e1e0ff Mon Sep 17 00:00:00 2001 From: Shengjiu Wang Date: Thu, 16 Apr 2020 20:25:37 +0800 Subject: ASoC: fsl_easrc: Add EASRC ASoC CPU DAI drivers EASRC (Enhanced Asynchronous Sample Rate Converter) is a new IP module found on i.MX8MN. It is different with old ASRC module. The primary features for the EASRC are as follows: - 4 Contexts - groups of channels with an independent time base - Fully independent and concurrent context control - Simultaneous processing of up to 32 audio channels - Programmable filter charachteristics for each context - 32, 24, 20, and 16-bit fixed point audio sample support - 32-bit floating point audio sample support - 8kHz to 384kHz sample rate - 1/16 to 8x sample rate conversion ratio Signed-off-by: Shengjiu Wang Signed-off-by: Cosmin-Gabriel Samoila Acked-by: Nicolin Chen Link: https://lore.kernel.org/r/260d7a9fbddf9fa90760d30095df60a4c25fd0a1.1587038908.git.shengjiu.wang@nxp.com Signed-off-by: Mark Brown --- sound/soc/fsl/Kconfig | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'sound/soc/fsl/Kconfig') diff --git a/sound/soc/fsl/Kconfig b/sound/soc/fsl/Kconfig index 65e8cd4be930..ea7b4787a8af 100644 --- a/sound/soc/fsl/Kconfig +++ b/sound/soc/fsl/Kconfig @@ -84,6 +84,17 @@ config SND_SOC_FSL_MICFIL Say Y if you want to add Pulse Density Modulation microphone interface (MICFIL) support for NXP. +config SND_SOC_FSL_EASRC + tristate "Enhanced Asynchronous Sample Rate Converter (EASRC) module support" + depends on SND_SOC_FSL_ASRC + select REGMAP_MMIO + select SND_SOC_GENERIC_DMAENGINE_PCM + help + Say Y if you want to add Enhanced ASRC support for NXP.
