0048 help
0049 Some peripherals on Bay Trail and Cherry Trail platforms signal a
0050 Power Management Event (PME) to the Power Management Controller (PMC)
0051 to wakeup the system. When this happens software needs to explicitly
0052 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
0053 IRQ storm on IRQ 9.
0054
0055 This is modelled in ACPI through the INT0002 ACPI device, which is
0056 called a "Virtual GPIO controller" in ACPI because it defines the
0057 event handler to call when the PME triggers through _AEI and _L02
0058 methods as would be done for a real GPIO interrupt in ACPI.

0101 This driver add support for the Intel Cherry Trail Whiskey Cove
0102 INT33FE ACPI device found on the GPD win and the GPD pocket.
0103
0104 The INT33FE ACPI device on these mini laptops contains I2cSerialBusV2
0105 resources for a MAX17042 Fuel Gauge, FUSB302 USB Type-C Controller
0106 and PI3USB30532 USB switch.
0107 This driver instantiates i2c-clients for these, so that standard
0108 i2c drivers for these chips can bind to the them.
0109
0110 If you enable this driver it is advised to also select
0111 CONFIG_TYPEC_FUSB302=m, CONFIG_TYPEC_MUX_PI3USB30532=m and
0112 CONFIG_BATTERY_MAX17042=m.

0119 This driver is for accessing the PSE (Programmable Service Engine) -
0120 an Embedded Controller like IP - using ISHTP (Integrated Sensor Hub
0121 Transport Protocol) to get battery, thermal and UCSI (USB Type-C
0122 Connector System Software Interface) related data from the platform.
0123 Users who don't want to use discrete Embedded Controller on Intel's
0124 Elkhartlake platform can leverage this integrated solution of
0125 ECLite which is part of PSE subsystem.

0150 help
0151 This driver provides support for modifying parameters on systems
0152 equipped with Intel's Rapid Start Technology. When put in an ACPI
0153 sleep state, these devices will wake after either a configured
0154 timeout or when the system battery reaches a critical state,
0155 automatically copying memory contents to disk. On resume, the
0156 firmware will copy the memory contents back to RAM and resume the OS
0157 as usual.

0174 help
0175 Intel Smart Connect is a technology intended to permit devices to
0176 update state by resuming for a short period of time at regular
0177 intervals. If a user enables this functionality under Windows and
0178 then reboots into Linux, the system may remain configured to resume
0179 on suspend. In the absence of any userspace to support it, the system
0180 will then remain awake until something triggers another suspend.
0181
0182 This driver checks to determine whether the device has Intel Smart
0183 Connect enabled, and if so disables it.

0191 CPU with higher performance to schedule tasks.
