Currently, it is assumed the host will sooner or later retrieve the
events from the sensor ring: It is only used by Android and the sensor
HAL is enabling the ring buffer at boot.
But if nobody processes the ring, and the ring is almost full, the EC will
generate interrupt for every new events.
This can happen with ARC, where events generated for ChromeOS
will be in the ring but nobody will process them until Android is
started.
Add a command to allow sending ring MKBP events. It will be used when
the IIO ring buffer is enabled / disabled.
It also can be used for preventing raising interrupt when the device is
about to go to sleep.

In order to retrieve the FW version string, the TPM register

a the pointer index to 0. The same register is then
read by the AP and each read will return up to 4 bytes of the

This change adds a ccd console command to control the usb endpoints.
The uart console command is moved into this command so 'ccd uart
[enable|disable]' controls the AP and EC TX signals instead of the
'uart' console command. CCD can be enabled using 'ccd enable'. This
switches the PHY used by the USB controller to be the external PHY.
Changing the PHY exposes the cr50, AP, and EC consoles as well as the
upgrading mechanisms for the AP, EC and cr50. The AP and EC consoles
will be read only until 'ccd uart enable' is called. Cr50 can be updated
using the usb upgrade endpoint. The EC and AP can be updated using the
USB SPI endpoint.
When CCD is disabled the usb controller will switch to using the AP PHY.
None of the endpoints will be visible to the host.
The USB SPI endpoint can be used to flash the EC or AP using
'flashrom -p raiden_debug_spi:target=[AP|EC]'. If CCD is not enabled
running flashrom using the raiden_debug_spi programmer will fail. Cr50
will not forward the commands to the external AP or EC ROM, so flashrom
will not be able to find the chip.
The UART TX signals are now controlled by the 'ccd uart' console
command instead of the 'uart' console command. The UART TX is enabled
separately from CCD, because we want to be able to enable CCD while
servo is connected, and having the cr50 UART TX pins wired directly to
the Servo TX lines could damage both devices. The AP and EC consoles
are be read only until 'ccd uart enable' is called. 'ccd uart disable'
disconnects the AP and EC TX pins from the UART peripheral.
When RDD becomes reliable on cr50, ccd_set_mode will select the PHY
being used by the g chip USB controller.

Full implementation of NvMem read, write, and commit functions.
Includes partition definitions, shared memory allocation, and
initialization function.
Includes a set of unit tests located in ec/test/nvmem.c which
verify functionality.
This module is required by Cr50, however this CL does not
include any Cr50 specific code.

The console adc command prints adc values in the

in the order they are enumerated in board.h, which is not

Previously usb_charger.c supported only pi3usb9281, but now support for
additional parts is required. Move pericom-specific code (including the
usb_charger tasks that handles various quirks of that part) to the
pi3usb9281 usb_switch driver.
Going forward, usb_switch drivers must implement
usb_charger_set_switches() and must have some method (such as a task or
interrupt handler) to update charge_manager with information about
attached chargers.

GPIO console commands currently only show input voltage level,
and can only set level on predefined outputs.
This change allows GPIOs to be cycled between output, input,
and alternate function, as well as displaying the mode and
asserted level (if any) in gpioget.
This change creates CONFIG_CMD_GPIO_EXTENDED
as the internal gpio interface needs to be changed to support
this, and I can't test the other architectures. It may be
worthwhile to add this for all, or not.
This change is also necessary also for servo micro JTAG and PD
UART support, as several pins are tied together on the flex
and stm32 outputs need to be variously active or in high-z
depending on mode.
