Document the ADIS16475 device devicetree bindings Signed-off-by: Nuno Sá <nuno.sa@analog.com> --- Changes in v2: * Remove burst32 property; * Rename clk-mode to adi,sync-mode; * Remove clock-names; * Add conditionals to state that clocks is only needed depending on adi,sync-mode property. Changes in v3: * Make use of 'allOf' in conditionals. Changes in v4: * Nothing changed.
