MT6873/8192 are highly integrated SoCs and use PMIC_MT6359 for
power management. This patch adds pwrap master driver to
access PMIC_MT6359.

I find this macro name a bit weird, because you are actually using
this mask on PWRAP_WACS2_RDATA register value (just like
PWRAP_GET_WACS_FSM below).
Should it be something like PWRAP_GET_WACS_ARB_FSM?!

Those !HAS_CAP tests are a little hard to read. Also, ret isn't really needed.
So I'd do this:
if (HAS_CAP(wrp->master->caps, PWRAP_CAP_ARB))
return PWRAP_GET_SWINF_2_FSM(val) == PWRAP_WACS_FSM_IDLE;
return PWRAP_GET_WACS_FSM(val) == PWRAP_WACS_FSM_IDLE;

Not 100% convinced if worth it, but you could also do:
if (HAS_CAP(wrp->master->caps, PWRAP_CAP_ARB))
val = adr;
else
val = (adr >> 1) << 16;
pwrap_writel(wrp, val, PWRAP_WACS2_CMD);

Similarly:
if (HAS_CAP(wrp->master->caps, PWRAP_CAP_ARB))
val = pwrap_readl(wrp, PWRAP_SWINF_2_RDATA_31_0);
else
val = pwrap_readl(wrp, PWRAP_WACS2_RDATA);
*rdata = PWRAP_GET_WACS_RDATA(val);
(or set the register address in an `reg` variable)
