From 675c0ee514f56ea39f6f550299621aafe9a53fc0 Mon Sep 17 00:00:00 2001 From: Matthias Reichl Date: Wed, 8 Nov 2017 21:03:31 +0100 Subject: [PATCH] ASoC: bcm2835: Support additional samplerates up to 384kHz Sample rates are only restricted by the capabilities of the clock driver, so use SNDRV_PCM_RATE_CONTINUOUS instead of SNDRV_PCM_RATE_8000_192000. Tests (eg with pcm5122) have shown that bcm2835 works fine in 384kHz/32bit stereo mode, so change the maximum allowed rate from 192kHz to 384kHz.
