Subject: Re: [PATCH v4 01/10] drivers: qcom: rpmh-rsc: Clean code reading/writing TCS regs/cmds

Quoting Douglas Anderson (2020-04-13 10:04:06)
> This patch makes two changes, both of which should be no-ops:
> 
> 1. Make read_tcs_reg() / read_tcs_cmd() symmetric to write_tcs_reg() /
>    write_tcs_cmd().
> 
> 2. Change the order of operations in the above functions to make it
>    more obvious to me what the math is doing.  Specifically first you
>    want to find the right TCS, then the right register, and then
>    multiply by the command ID if necessary.
