bee58e5d3e npcx: set eSPI speed to max supported by hardware
the npcx7 can only run eSPI at (up to) 50MHz while the npcx5 can go up
to 66MHz.  so, set the max speed to whatever the hardware can actually
do.  the bit pattern for 66MHz is "reserved" on the npcx7, so let's
not even define it in the npcx7 case.

52e5ab0730 eve: Use PCH ACOK signal to control Deep Sleep entry
Deep Sleep states (DS3, DS5) are a special mode of the Intel PCH chipset
that has very limited wake capabilities and breaks a number of common
user expected behahviors.

In particular, when in Deep S3 the USB ports are turned off and cannot
continue to charge, wake the system, or maintain their internal state
as they will lose 5V power.  This is particularly painful with gnubby
devices as they will need unlocked after every DS3 suspend/resume cycle.

The only external signal that the PCH uses to determine whether or not
to enter Deep Sx states is the ACPRESENT (aka ACOK) pin.

Currently this pin is simply buffered from the charger and will be
asserted whenever a charger is connected.  This change extends the EC
control over the pin to also assert ACPRESENT if either Type-C port is
currently supplying VBUS.

Now when a USB device is inserted the system will be enter S3 state,
but not go into Deep S3 state.  This allows the USB device to continue
to charge, maintain it's internal state, and wake the system.

BUG=b:64406191
BRANCH=eve
TEST=verify GPIO_PCH_ACOK pin from the EC in different scenarios and
test that system goes into S3 or DS3 state as expected:
1) no charger, no USB device: ACOK not asserted, DS3 enabled
2) charger but no USB device: ACOK asserted, DS3 disabled
3) no charger but USB device: ACOK asserted, DS3 disabled
4) charger and USB device:    ACOK asserted, DS3 disabled

730491df20 stm32: add internal flash support for STM32H7 family
The STM32H7 family has 2 banks of flash (with 2 hardware controllers
able to do 2 parallel operations at the same time).
Each bank of flash has 4 or 8 128-kB erase blocks (1MB and 2MB
variants).
The flash can only be written by 256-bit word (with an additional 10-bit
ECC computed by the hardware).

For the flash write-protection, we cannot use our 'classical' PSTATE
scheme as the erase-blocks are too large (128-kB) to dedicate one to
this and the embedded word in the RO partition would not work as the
flash has ECC and triggers bus-fault when the ECC is incorrect (which
includes the case where the 256-bit word is written a second time).
So we will do the following:
- use the RSS1 bit in the option bytes as the Write-Protect enabled bit.
- if the WP GPIO is set, lock at startup the option bytes until next
  reboot.

When AP requests cold reboot, currently EC does not perform PMIC
reset because chipset_handle_reboot is executed only after EC jumps

96470c4dfb lpc: Prevent watchdog reset caused by KBC IBF interrupt on chromebox.
Since there is no KEYPROTO task on chromebox such as fizz and sion, lpc
driver doesn't declare KBC IBF/OBE ISRs for these events. If host put
data in ec's KBC input buffer unexpectedly, exception_panic() will be
executed in default_handler. Then we will see ec print
"=== PROCESS EXCEPTION: 29 ====== xPSR: 01000000 ===" message without

This CL fixed this symptom by turning off KBC if there is no KEYPROTO task.

bb5f21ed1a Fizz: Monitor input current (version 2.0)
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.

d940d2a991 common: Add support for PWM LEDs.
This commit adds support for a common framework for PWM controlled LEDs.
If there are multiple LEDs, they will all follow the same pattern.  The
pattern is such that it follows the Chrome OS LED behaviour
specification, essentially a similar version of led_policy_std.c but for
PWM controlled LEDs.

To use this framework, a board must do the following:

- First, define the number of logical PWM LEDs which will be controlled
  by this common policy, CONFIG_LED_PWM_COUNT.

- Then declare those logical LEDs and define the PWM channels that
 comprise those LEDs. (struct pwm_led pwm_leds[]).

- Next, define what each color should look like (struct pwm_led
  led_color_map[]).

By default, the colors follow the recommended colors in the LED
behaviour spec, which assume an LED with a red and green channel.  If a
board differs or wishes to change the colors in general, they can
redefine the colors (CONFIG_LED_PWM_*_COLOR) as they see fit.  The
colors must be one in enum ec_led_colors.  These colors are the ones
that can represent the charging state, SoC state, etc.
