Also the pclk isn't coming from the cru but from some external source at least on px30 and rk3288 (and I guess others as well), so maybe that deserves a distinct name. Maybe something like aclk, hclk, pclkin or so? Also the cif_out clock is not actual part of the CIF block, on both the rk3288 and px30 (and probably the others too) it is generated in the SoC's clock controller and then just led to an output-pin on the soc, so I'd assume a peripheral wanting to use that would take care of setting+enabling that clock (similar to the i2s mclk)? > + > + resets: > + items: > + - description: Reset CIF A > + - description: Reset CIF H > + - description: Reset CIF PCLK IN > + > + reset-names: > + items: > + - const: rst_cif_a > + - const: rst_cif_h > + - const: rst_cif_pclkin Same here, maybe just "axi", "ahb", "pclkin" like the vop resets do?
