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.

Setting the VSYSREG_SET register as per Charge State Machine of
the BD9995X datasheet.
1. Set VSYSREG_SET <= VBAT so that the charger is in Fast-Charge
state when charging.
2. Set VSYSREG_SET > VBAT so that the charger is in Pre-Charge
state when not charging or discharging.
BUG=chrome-os-partner:55220
BRANCH=none
TEST=Manually tested on Reef. Observed 'Charger State Machine Status'
register value when charging it is in Fast-Charge state and
when not charging/discharging it is in Pre-Charge state.

- Defined the config option CONFIG_USB_PD_DTS to board.h.
- Added ccd_set_mode function in board.c
- Removed ccd attach/detach functions from board.c as that function is
- now integrated in the the usb_pd state machine.
- Removed the fixed polarity that was being used in usb_pd_config.h so
that the DUT port could connect as a SNK device.
- Defined PD_ROLE_DEFAULT to override the value in usb_Pd.h so that
CHG is SNK and DUT is SRC
This set of changes allows servo_v4 to act like a suzyq. Hoever, PD
messaging is still not supported. The CHG port can still connect as a
SNK device, but VBUS on the DUT is only being provided by the host and
not the CHG port.
BUG=chrome-os-partner:61878
BRANCH=None
TEST=Manual Connected zinger to CHG port and verifed via servo_v4
console that it reached SNK_READY. Connected DUT port to Reef and
verified that it reached SRC_ACCESSORY state and that the correct SBU
polarity was selected and that lsusb shows H1 as a USB device.

The cipher command implementation had to change to account for reduced
heap size and to improve coverage.
Note that the goal of this command is not to verify correctness of the
encryption services provided by the dcrypto, but to allow to exercise
the crypto engine on multiple passes, each time using the same clear
text but different initialization vector.

This patch locks the ec.
This also locks PD communication until sysjump to RW.
We don't want to allow communication to outside world until
we jump to RW. This can by overridden with the removal of
the write protect screw to allow for easier testing.

We wanted to reduce the number of interrupts that uart was producing so
we increased the number of characters needed in the fifos before it
would trigger an interrupt. Right now it needs 4 characters. If you
aren't printing a multiple of four characters, then not all text will be
printed.
This change changes the rxilvl back to 1. This will make using the
consoles and testing cr50 functionality more reliable.
