> Subject: [Intel-wired-lan] [PATCH v4 03/15] ice: fix E825-C TSPLL register 
> definitions
>
> The E825-C hardware has a slightly different register layout for register
19 of the Clock Generation Unit and TSPLL. The fbdiv_intgr value can be 10 bits 
wide.
>
> Additionally, most of the fields that were in register 24 are made available 
> in register 23 instead. The programming logic already has a corrected 
> definition for register 23, but it incorrectly still used the 8-bit 
> definition of fbdiv_intgr. This results in truncating some of the values of 
> fbdiv_intgr, including the value used for the 156.25MHz signal.
>
> The driver only used register 24 to obtain the enable status, which we should 
> read from register 23. This results in an incorrect output for the log 
> messages, but does not change any functionality besides disabled-by-default 
> dynamic debug messages.
>
> Fix the register definitions, and adjust the code to properly reflect the 
> enable/disable status in the log messages.
