| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When OOB is disabled, FW will be power gated when system is in S3/S4/S5 which is the same behavior with legacy ISH FW. When OOB is enabled, FW will always power on which is totally different comparing to legacy ISH FW. So NO_D3 flag is not enough to check FW's status after resume. Here we can use IPC FW status register to check host link status. If it is false, it means FW get reset after power gated, need go through the whole initialization flow; If it is true, it means FW is alive, just set host ready bit to let fw know host is up.

|\ | | | | | | | | | | | | - fixes for handling power management for intel-ish devices with NO_D3 flag set, from Zhang Lixu Signed-off-by: Jiri Kosina <jkosina@suse.cz>
| * HID: intel-ish-hid: ipc: set NO_D3 flag only when neededZhang Lixu2019-08-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the NO_D3 flag is set in ish_probe(), and cleared in ish_remove(). So even if the system goes into S3, ISH is still in D0i3 state. It makes more sense that put ISH into D3 as system goes into S3 and put ISH into D0i3 as system goes into suspend-to-idle. I remove the NO_D3 setting in ish_probe(), so that ISH can enter D3 state when system enters S3. Only set N0_D3 flag when system enters the suspend-to-idle or platform specified, and clear it when system resume. When the ISH enters D3, the FW will check the DMA bit status. If the DMA bit is set, the FW will reset automatically. So the DMA bit need be clear before putting ISH into D3 state.

* HID: intel-ish-hid: ipc: check FW status to distinguish ISH resume pathsEven Xu2017-02-081-0/+12
| | | | | | | | | | | | | For ISH resume, there are two paths, they need different way to handle: one where ISH is not powered off, in that case a simple resume message is enough, in other case we need a reset sequence. We can use ISH FW status to distinguish those two cases and handle them properly.
