Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx.

Subject: [PATCH 229/454] ASoC: pcm512x: implement set_tdm_slot interface
|
|
|
|
PCM512x can accept data padded with additional BCLK cycles
|
|
but the driver currently lacks an interface to configure this.
|
|
|
|
This leads to the problem that S24_LE format in master mode
|
|
can result in non-integer clock divisors and pcm512x running
|
|
at a rather off rate.
|
|
|
|
For example 48kHz with 48fs BCLK and SCLK at 24.576MHz uses
|
|
a divisor of 10 (rounded down from 10.6666) and results in a
|
|
51.2kHz LRCLK. With 64fs BCLK a divisor of 8 is used and
|
|
LRCLK runs at exactly 48kHz.
|
|
|
|
Fix this by providing a minimal set_tdm_slot implementation
|
|
so machine drivers can optionally configure custom BCLK ratios.
