* PTN5150 CC (Configuration Channel) Logic device
PTN5150 is a small thin low power CC logic chip supporting the USB Type-C
connector application with CC control logic detection and indication functions.
It is interfaced to the host controller using an I2C interface.
Required properties:
- compatible: should be "nxp,ptn5150"
- reg: specifies the I2C slave address of the device
- int-gpio: should contain a phandle and GPIO specifier for the GPIO pin
connected to the PTN5150's INTB pin.
- vbus-gpio: should contain a phandle and GPIO specifier for the GPIO pin which
is used to control VBUS.
- pinctrl-names : a pinctrl state named "default" must be defined.
- pinctrl-0 : phandle referencing pin configuration of interrupt and vbus
control.
Example:
ptn5150@1d {
compatible = "nxp,ptn5150";
reg = <0x1d>;
int-gpio = <&msmgpio 78 GPIO_ACTIVE_HIGH>;
vbus-gpio = <&msmgpio 148 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&ptn5150_default>;
status = "okay";
};

Overview
========
Nitro Enclaves (NE) is a new Amazon Elastic Compute Cloud (EC2) capability
that allows customers to carve out isolated compute environments within EC2
instances [1].
For example, an application that processes sensitive data and runs in a VM,
can be separated from other applications running in the same VM. This
application then runs in a separate VM than the primary VM, namely an enclave.
An enclave runs alongside the VM that spawned it. This setup matches low latency
applications needs. The resources that are allocated for the enclave, such as
memory and CPUs, are carved out of the primary VM. Each enclave is mapped to a
process running in the primary VM, that communicates with the NE driver via an
ioctl interface.
In this sense, there are two components:
1. An enclave abstraction process - a user space process running in the primary
VM guest that uses the provided ioctl interface of the NE driver to spawn an
enclave VM (that's 2 below).
There is a NE emulated PCI device exposed to the primary VM. The driver for this
new PCI device is included in the NE driver.
The ioctl logic is mapped to PCI device commands e.g. the NE_START_ENCLAVE ioctl
maps to an enclave start PCI command. The PCI device commands are then
translated into actions taken on the hypervisor side; that's the Nitro
hypervisor running on the host where the primary VM is running. The Nitro
hypervisor is based on core KVM technology.
2. The enclave itself - a VM running on the same host as the primary VM that
spawned it. Memory and CPUs are carved out of the primary VM and are dedicated
for the enclave VM. An enclave does not have persistent storage attached.
The memory regions carved out of the primary VM and given to an enclave need to
be aligned 2 MiB / 1 GiB physically contiguous memory regions (or multiple of
this size e.g. 8 MiB). The memory can be allocated e.g. by using hugetlbfs from
user space [2][3]. The memory size for an enclave needs to be at least 64 MiB.
The enclave memory and CPUs need to be from the same NUMA node.
An enclave runs on dedicated cores. CPU 0 and its CPU siblings need to remain
available for the primary VM. A CPU pool has to be set for NE purposes by an
user with admin capability. See the cpu list section from the kernel
documentation [4] for how a CPU pool format looks.
An enclave communicates with the primary VM via a local communication channel,
using virtio-vsock [5]. The primary VM has virtio-pci vsock emulated device,
while the enclave VM has a virtio-mmio vsock emulated device. The vsock device
uses eventfd for signaling. The enclave VM sees the usual interfaces - local
APIC and IOAPIC - to get interrupts from virtio-vsock device. The virtio-mmio
device is placed in memory below the typical 4 GiB.
The application that runs in the enclave needs to be packaged in an enclave
image together with the OS ( e.g. kernel, ramdisk, init ) that will run in the
enclave VM. The enclave VM has its own kernel and follows the standard Linux
boot protocol [6].
The kernel bzImage, the kernel command line, the ramdisk(s) are part of the
Enclave Image Format (EIF); plus an EIF header including metadata such as magic
number, eif version, image size and CRC.
Hash values are computed for the entire enclave image (EIF), the kernel and
ramdisk(s). That's used, for example, to check that the enclave image that is
loaded in the enclave VM is the one that was intended to be run.
These crypto measurements are included in a signed attestation document
generated by the Nitro Hypervisor and further used to prove the identity of the
enclave; KMS is an example of service that NE is integrated with and that checks
the attestation doc.
The enclave image (EIF) is loaded in the enclave memory at offset 8 MiB. The
init process in the enclave connects to the vsock CID of the primary VM and a
predefined port - 9000 - to send a heartbeat value - 0xb7. This mechanism is
used to check in the primary VM that the enclave has booted. The CID of the
primary VM is 3.
If the enclave VM crashes or gracefully exits, an interrupt event is received by
the NE driver. This event is sent further to the user space enclave process
running in the primary VM via a poll notification mechanism. Then the user space
enclave process can exit.

Support is provided through the sysfs entry ``w1_slave``. Each open and
read sequence will initiate a temperature conversion, then provide two
lines of ASCII output. The first line contains the nine hex bytes
read along with a calculated crc value and YES or NO if it matched.
If the crc matched the returned values are retained. The second line
displays the retained values along with a temperature in millidegrees
Centigrade after t=.
Alternatively, temperature can be read using temperature sysfs, it
return only temperature in millidegrees Centigrade.
Alternatively, temperature can be read using ``temperature`` sysfs, it

A bulk read of all devices on the bus could be done writing ``trigger``
to ``therm_bulk_read`` entry at w1_bus_master level. This will
send the convert command to all devices on the bus, and if parasite
powered devices are detected on the bus (and strong pullup is enabled
in the module), it will drive the line high during the longer conversion
time required by parasited powered device on the line. Reading
therm_bulk_read will return 0 if no bulk conversion pending,
``therm_bulk_read`` will return 0 if no bulk conversion pending,
-1 if at least one sensor still in conversion, 1 if conversion is complete
but at least one sensor value has not been read yet. Result temperature is
then accessed by reading the temperature sysfs entry of each device, which
then accessed by reading the ``temperature`` entry of each device, which
may return empty if conversion is still in progress. Note that if a bulk
read is sent but one sensor is not read immediately, the next access to
temperature on this device will return the temperature measured at the
``temperature`` on this device will return the temperature measured at the
time of issue of the bulk read command (not the current temperature).
Writing a value between 9 and 12 to the sysfs w1_slave file will change the
precision of the sensor for the next readings. This value is in (volatile)
SRAM, so it is reset when the sensor gets power-cycled.
A strong pullup will be applied during the conversion if required.
To store the current precision configuration into EEPROM, the value 0
has to be written to the sysfs w1_slave file. Since the EEPROM has a limited
amount of writes (>50k), this command should be used wisely.
``conv_time`` is used to get current conversion time (read), and
adjust it (write). A temperature conversion time depends on the device type and
it's current resolution. Default conversion time is set by the driver according
to the device datasheet. A conversion time for many original device clones
deviate from datasheet specs. There are three options: 1) manually set the
correct conversion time by writing a value in milliseconds to ``conv_time``; 2)
auto measure and set a conversion time by writing ``1`` to
``conv_time``; 3) use ``features`` to enable poll for conversion
completion. Options 2, 3 can't be used in parasite power mode. To get back to
the default conversion time write ``0`` to ``conv_time``.
Alternatively, resolution can be set or read (value from 9 to 12) using the
dedicated resolution sysfs entry on each device. This sysfs entry is not
present for devices not supporting this feature. Driver will adjust the
correct conversion time for each device regarding to its resolution setting.
In particular, strong pullup will be applied if required during the conversion
duration.
Writing a resolution value (in bits) to ``w1_slave`` will change the
precision of the sensor for the next readings. Allowed resolutions are defined by
the sensor. Resolution is reset when the sensor gets power-cycled.
The write-only sysfs entry eeprom is an alternative for EEPROM operations:
* 'save': will save device RAM to EEPROM
* 'restore': will restore EEPROM data in device RAM.
To store the current resolution in EEPROM, write ``0`` to ``w1_slave``.
Since the EEPROM has a limited amount of writes (>50k), this command should be
used wisely.
ext_power syfs entry allow tho check the power status of each device.
* '0': device parasite powered
* '1': device externally powered
Alternatively, resolution can be read or written using the dedicated
``resolution`` entry on each device, if supported by the sensor.
sysfs alarms allow read or write TH and TL (Temperature High an Low) alarms.
Some non-genuine DS18B20 chips are fixed in 12-bit mode only, so the actual
resolution is read back from the chip and verified.
Note: Changing the resolution reverts the conversion time to default.
The write-only sysfs entry ``eeprom`` is an alternative for EEPROM operations.
Write ``save`` to save device RAM to EEPROM. Write ``restore`` to restore EEPROM
data in device RAM.
``ext_power`` entry allows checking the power state of each device. Reads
``0`` if the device is parasite powered, ``1`` if the device is externally powered.
Sysfs ``alarms`` allow read or write TH and TL (Temperature High an Low) alarms.
Values shall be space separated and in the device range (typical -55 degC
to 125 degC). Values are integer as they are store in a 8bit register in

detection algorithm. This feature allows you to determine the physical
location of the chip in the 1-wire bus without needing pre-existing
knowledge of the bus ordering. Support is provided through the sysfs
w1_seq file. The file will contain a single line with an integer value
``w1_seq``. The file will contain a single line with an integer value
representing the device index in the bus starting at 0.
``features`` sysfs entry controls optional driver settings per device.
Insufficient power in parasite mode, line noise and insufficient conversion
time may lead to conversion failure. Original DS18B20 and some clones allow for
detection of invalid conversion. Write bit mask ``1`` to ``features`` to enable
checking the conversion success. If byte 6 of scratchpad memory is 0xC after
conversion and temperature reads 85.00 (powerup value) or 127.94 (insufficient
power), the driver returns a conversion error. Bit mask ``2`` enables poll for
conversion completion (normal power only) by generating read cycles on the bus
after conversion starts. In parasite power mode this feature is not available.
Feature bit masks may be combined (OR). More details in

compatible with DS18B20. Added are lowest 2\ :sup:`-5`, 2\ :sup:`-6` temperature
bits in Config register; R2 bit in Config register enabling 13 and 14 bit
resolutions. The device is powered up in 14-bit resolution mode. The conversion
