Subject: [PATCH v3 2/2] ASoC: meson: g12a-toacodec: add support for SM1 TOACODEC
This adds support for the TOACODEC found in Amlogic SM1 SoCs.
The bits are shifted for more selection of clock sources, so this only
maps the same support for G12A to the SM1 bits.
Signed-off-by: Neil Armstrong <narmstrong@...libre.com>
