These patches are to put the ISH into D3 when system enter S3 and put the ISH into D0i3 when system enter S0ix. I tested these patches on the following platforms: ISH 5.2: ICL ISH 5.0: CNL CFL WHL CML ISH 4.0: GLK ISH 3.0: KBL Test steps: * Run the IIO Sensor tool to read the accel_3d sensor data * Run cmd "echo mem > /sys/power/state" to suspend-to-mem * Press the keyboard to wake up OS. * Check if the tool can get the sensor data after OS resume. * Run cmd "echo freeze > /sys/power/state" to suspend-to-idle * Press the keyboard to wake up OS. * Check if the tool can get the sensor data after OS resume. Test results: The tool can get the accel_3d sensor data after resuming from both suspend-to-mem and suspend-to-idle. Changes from v1: * Fix the indentation issue * Elaborate the reason to remove the NO_D3 flag * Split the PATCH v1 to three changes, and try to minimize the lines change Zhang Lixu (3): HID: intel-ish-hid: ipc: set NO_D3 flag only when needed HID: intel-ish-hid: ipc: make ish suspend paths clear HID: intel-ish-hid: ipc: check the NO_D3 flag to distinguish resume paths drivers/hid/intel-ish-hid/ipc/hw-ish.h | 1 + drivers/hid/intel-ish-hid/ipc/ipc.c | 2 +- drivers/hid/intel-ish-hid/ipc/pci-ish.c | 95 +++++++++++++++---------- 3 files changed, 61 insertions(+), 37 deletions(-) -- 2.17.1
