Currently if an interrupt is pending before it is enabled the interrupt
will fire immediately. In most cases this is fine, but if we want to
use the interrupt to trigger something like waking the AP it should be
sure that it won't immediately fire once enabled.
For example: on the Eve board we have the trackpad interrupt run to the
AP and the EC in order to support wake from Deep S3 (magic AP state that
only the EC can wake it from). This interrupt is used in S0 by the AP
while ignored by the EC, and then enabled on the transition to S3 in
order to be able to wake. Since it has been active the interrupt may
be pending in the EC (depending on the chip), which can result in the
interrupt firing immediately and waking the AP.

This follows the basics of what is decribed in
RM0091 Reference Manual 30.5.5 Suspend/Resume events .
We call enable/disable_sleep at suspend/resume, to make
sure the EC stays awake when USB is connected and active.
We also call clock_enable/disable_module, which is stubbed on
stm32f0, but can be used on other devices in the family.
This also fixes interrupt handling in usb_interrupt, by only
clearing interrupt bits that were handled instead of resetting
them all, which is racy, and can potentially lead to issues
if reset comes soon after a resume event.

Our previous idea to cut Rd for many reset cases cannot work if cr50
consistently resets the EC by asserting the reset pin shortly after
power-on. Therefore, make a decision based upon whether battery-backed
memory indicates we previously negotiated a PD power contract as a sink.
If we previously did not negotiate a contract, or if power was removed
from the device (causing battery-backed memory to wipe) then we can
assume that we don't have an active power contract.

first then wait for 10ms.
This code doesn't have the wake-up read to avoid 10ms delay.
Instead, we call this function immediately after the chip is

Once it's called, the chip info will be stored in cache, which
can be accessed by tcpc_get_chip_info without worrying about

In case there is a sudden power loss to PCH, then there are no eSPI VW
messages sent from the PCH to EC indicating power state transition into
S5. Instead, the eSPI compatibility spec defines such events as global
reset events. For global reset events, eSPI_Reset# signal is asserted
without SLP_SUS# being asserted. This acts as an indication to the EC
that there was a global reset event.
Add a callback chipset_handle_espi_reset_assert that takes any necessary
action whenever eSPI_Reset# pin is asserted. On skylake, it would check
if power button was being pressed and release the button.

The cr50 needs to be aware of the power state of the system and of the
moment when the AP is reset, because this is when the TPM needs to be
reset too.
Arm and x86 platforms provide different hints in these cases.
In case of x86 there is a single signal cr50 can rely on: PLT_RST_L.
This active low signal is asserted when the system is going into any
power state deeper than s0ix. The cr50 can fall into deep sleep when
PLT_RST_L is asserted, and has to wake up and reset the TPM when this
signal is deasserted. There could be other wake triggers, but the tpm
should not be reset unless PLT_RST_L is inactive. It is also important
not to fall into deep sleep when PLT_RST_L is pulsed to reboot the
system.
In case of ARM there are two separate signals. Deasserting SYS_RST_L
signal is the trigger to reset the TPM, The GPIO_DETECT_AP going low
for a duration of time is the indication of the AP going into some
kind of sleep mode. The ARM case requires more clarification.
This adds run time configuration of the the sleep state control input.
Once the input turns low, the CHIPSET_SHUTDOWN signal is sent and deep
sleep mode is enabled. Again, this will require adjustment for ARM
platforms.
The wake from deep sleep state is controlled by the wake pins as
before, but by level instead of edge. This makes sure that in case the
trigger for deep sleep goes away while deep sleep preparation is under
way, the device resumes immediately instead of getting stuck missing
the edge.
The TPM_RST_ input is now triggering interrupts on deassertion
- this is the moment when the TPM needs to be reset. The ISR is being
renamed accordingly.
The processing previously happening inside the ISR is being moved into
a deferred function running on the hooks task context.
There is no need to invoke TPM reset related functions from the PMU
wake up ISR anymore.

The INAs are only used for development and testing
purposes. Therefore, the 3.3V rail to the INAs is off by default and
the I2Cm module is not enabled. Enabling INA power and connecting the
I2Cm module was done at the beginning of each USB to I2C request. The
problem with this approach is that INA measurments didn't always
succeed due to not enough time for the INAs to initialize.
Rather than add some arbitrary delay, it is better to tie the INAs to
when rdd is attached/detached. It is only when rdd is attached that
the INAs will be accessed, so there is no need to enable/disable for
each individual I2C transaction.
This CL ties the enabling/disabling of the INA and I2Cm module to the
rdd state. This change makes the previous use of
usb_i2c_board_enable() and usb_i2c_board_disable() obslete.
