Subject: [PATCH 117/454] 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.
