12*7d0873ebSEmmanuel Vadotdescription: |
13*7d0873ebSEmmanuel Vadot  There are several clocks that are generated outside the SoC. It is expected
14*7d0873ebSEmmanuel Vadot  that they are defined using standard clock bindings with following
15*7d0873ebSEmmanuel Vadot  clock-output-names and/or provided as clock inputs to this clock controller:
16*7d0873ebSEmmanuel Vadot   - "fin_pll" - PLL input clock (xtal/extclk) - required,
17*7d0873ebSEmmanuel Vadot   - "xusbxti" - USB xtal - required,
18*7d0873ebSEmmanuel Vadot   - "iiscdclk0" - I2S0 codec clock - optional,
19*7d0873ebSEmmanuel Vadot   - "iiscdclk1" - I2S1 codec clock - optional,
20*7d0873ebSEmmanuel Vadot   - "iiscdclk2" - I2S2 codec clock - optional,
21*7d0873ebSEmmanuel Vadot   - "pcmcdclk0" - PCM0 codec clock - optional,
22*7d0873ebSEmmanuel Vadot   - "pcmcdclk1" - PCM1 codec clock - optional, only S3C6410.
23*7d0873ebSEmmanuel Vadot
24*7d0873ebSEmmanuel Vadot  All available clocks are defined as preprocessor macros in
25*7d0873ebSEmmanuel Vadot  include/dt-bindings/clock/samsung,s3c64xx-clock.h header.
