Having a few problems with the description. There is only one LPO clock 
input on the 43752 chipset. From the AMPAK AP6275P datasheet:

| 31 | LPO_IN | I | External Low Power Clock input (32.768KHz) |

I would suggest to use the description from the datasheet or something 
similar.

This does not match your DTS. DTS is different, e.g. does not have
compatible. There are required properties here, some of which are required.

Best regards,

Hi Jacobe,

thanks for taking care of this. According to CYW43455 datasheet which is
also covered by this binding, there are more clocks in the hardware
design, so i suggest to reword subject and commit message that this
patch only adds the low power clock.
