Fizz has three FETs connected to three registers: PR257, PR258,
PR7824. These control the thresholds of the current monitoring
system.
PR257 PR7824 PR258
For BJ (65W or 90W) off off off
For 4.35A (87W) on off off
For 3.25A (65W) off off on
For 3.00A (60W) off on off
The system power consumption is capped by PR259, which is stuffed
differently depending on the SKU (65W v.s. 90W or U42 v.s. U22).
So, we only need to monitor type-c adapters. For example:
a 90W system powered by 65W type-c charger
b 65W system powered by 60W type-c charger
c 65W system powered by 87W type-c charger
In a case such as (c), we actually do not need to monitor the current
because the max is capped by PR259.
AP is expected to read type-c adapter wattage from EC and control
power consumption to avoid over-current or system browns out.
The current monitoring system doesn't support less than 3A
(e.g. 2.25A, 2.00A). These currents most likely won't be enough to
power the system. However, if they're needed, EC can monitor
PMON_PSYS and trigger H_PROCHOT by itself.
BUG=b:72883633,b:64442692,b:72710630
BRANCH=none
TEST=Boot Fizz on 60W/87W/BJ charger. Verify GPIOs are set as expected.
