title: Samsung S3C6400 SoC clock controller
maintainers:
- Krzysztof Kozlowski <krzk@kernel.org>
description: |
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names and/or provided as clock inputs to this clock controller:
- "fin_pll" - PLL input clock (xtal/extclk) - required,
- "xusbxti" - USB xtal - required,
- "iiscdclk0" - I2S0 codec clock - optional,
- "iiscdclk1" - I2S1 codec clock - optional,
- "iiscdclk2" - I2S2 codec clock - optional,
- "pcmcdclk0" - PCM0 codec clock - optional,
- "pcmcdclk1" - PCM1 codec clock - optional, only S3C6410.
All available clocks are defined as preprocessor macros in
include/dt-bindings/clock/samsung,s3c64xx-clock.h header.
