47 select GPIOLIB_IRQCHIP
48 help
49 Some peripherals on Bay Trail and Cherry Trail platforms signal a
50 Power Management Event (PME) to the Power Management Controller (PMC)
51 to wakeup the system. When this happens software needs to explicitly
52 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
53 IRQ storm on IRQ 9.
54
55 This is modelled in ACPI through the INT0002 ACPI device, which is
56 called a "Virtual GPIO controller" in ACPI because it defines the
57 event handler to call when the PME triggers through _AEI and _L02
58 methods as would be done for a real GPIO interrupt in ACPI.
59

112 This driver add support for the Intel Cherry Trail Whiskey Cove
113 INT33FE ACPI device found on the GPD win and the GPD pocket.
114
115 The INT33FE ACPI device on these mini laptops contains I2cSerialBusV2
116 resources for a MAX17042 Fuel Gauge, FUSB302 USB Type-C Controller
117 and PI3USB30532 USB switch.
118 This driver instantiates i2c-clients for these, so that standard
119 i2c drivers for these chips can bind to the them.
120
121 If you enable this driver it is advised to also select
122 CONFIG_TYPEC_FUSB302=m, CONFIG_TYPEC_MUX_PI3USB30532=m and
123 CONFIG_BATTERY_MAX17042=m.

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

160 depends on ACPI
161 help
162 This driver provides support for modifying parameters on systems
163 equipped with Intel's Rapid Start Technology. When put in an ACPI
164 sleep state, these devices will wake after either a configured
165 timeout or when the system battery reaches a critical state,
166 automatically copying memory contents to disk. On resume, the
167 firmware will copy the memory contents back to RAM and resume the OS
168 as usual.

184 depends on ACPI
185 help
186 Intel Smart Connect is a technology intended to permit devices to
187 update state by resuming for a short period of time at regular
188 intervals. If a user enables this functionality under Windows and
189 then reboots into Linux, the system may remain configured to resume
190 on suspend. In the absence of any userspace to support it, the system
191 will then remain awake until something triggers another suspend.
192
193 This driver checks to determine whether the device has Intel Smart
194 Connect enabled, and if so disables it.
