Subject: [RFC PATCH 0/5] Flexible sysclk/pll configuration
This series attempts to add flexible system clock (sysclk) and pll
configuration for the DAI controller from simple card or audio graph
card.
Sysclk configuration
====================
Motivation:
-----------
The problem this tries to address is, some Codecs may have
multiple clocks and multiple sources for its sysclk. For example
sysclk may depend on MCLK provided by SoC or it may used an
internal pll. The simple card or audio graph card driver is
generic and can be used on multiple platforms. So if a platform
using this driver needs a generic configuration, then the Codec
specific stuff cannot be hardcoded in the driver. Hence it would
be better if the info is driven from DT, especially from a
Codec DAI or endpoint subnode.
Solution:
---------
"system-clock-id" and "system-clock-source" DT properties can be
exposed for a flexible sysclk configuration. These properties
go into a Codec DAI or endpoint subnode.
Please note that other sysclk related properties like
"system-clock-frequency" and "system-clock-direction-out" are
already present.
Currently snd_soc_dai_set_sysclk() does not have an argument
for source. This series adds this additional field and updates
all the required drivers. This is needed because ideally sysclk
"clk_id" and "source" fields are different. Some drivers are
making use of "clk_id" field to program source information.
**May be this needs to be corrected going ahead**
Pll configuration
=================
Motivation:
-----------
Similar to sysclk configuration, pll configuration also needs
little more flexibility. If a Codec has internal pll and it
can be sourced from multiple clocks a specific configuration
may be required for a given platform.
Some of the cases are:
- MCLK (supplied by SoC) --> Codec pll -> Codec sysclk
- SoC I2S bit clock (BCLK) --> Codec pll -> Codec sysclk
Solution:
---------
Approach is similar to what is done for extending sysclk
flexibility. Following DT properties are added to address the
same.
"pll-id"
"pll-source"
"pll-input-reference"
"pll-output-reference"
"pll-input-frequency"
"pll-output-frequency"
All these are optional properties. Simple card or audio graph
card drivers can use above info and call snd_soc_dai_set_pll()
for necessary configuration.
Sameer Pujar (5):
ASoC: soc-component: Fix return value of snd_soc_component_set_pll()
ASoC: soc-dai: Add sysclk source to snd_soc_dai_set_sysclk()
ASoC: audio-graph-card: Add bindings for sysclk and pll
ASoC: simple-card-utils: Parse sysclk id and source
ASoC: simple-card-utils: Support pll configuration
