* | Bluetooth: Rename driver .prevent_wake to .wakeupLuiz Augusto von Dentz2021-10-024-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | prevent_wake logic is backward since what it is really checking is if the device may wakeup the system or not, not that it will prevent the to be awaken. Also looking on how other subsystems have the entry as power/wakeup this also renames the force_prevent_wake to force_wakeup in vhci driver.

| | | | | | | | | | | | | | | | | | | | | | | | Some un-support wakeup platforms keep USB power and suspend signal is coming late, this makes Realtek some chip keep its firmware, and make it never load new firmware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recently added H5_WAKEUP_DISABLE h5->flags flag gets checked in h5_btrtl_open(), but it gets set in h5_serdev_probe() *after* calling hci_uart_register_device() and thus after h5_btrtl_open() is called, set this flag earlier. Also on devices where suspend/resume involves fully re-probing the HCI, runtime-pm suspend should not be used, make the runtime-pm setup conditional on the H5_WAKEUP_DISABLE flag too. This fixes the HCI being removed and then re-added every 10 seconds because it was being reprobed as soon as it was runtime-suspended.

However, there's the capability for Realtek devices to apply USB wakeup. In this commit, remove WAKEUP_DISABLE feature for Realtek devices. If users would switch wakeup, they should access "/sys/bus/usb/.../power/wakeup" In this commit, it also adds the feature as WAKEUP_AUTOSUSPEND for Realtek devices because it should set do_remote_wakeup on autosuspend.

Enable the flag for Realtek, restoring the previous behavior for non-Realtek devices.

* Bluetooth: btintel: Add combined setup and shutdown functionsTedd Ho-Jeong An2021-08-052-0/+241
| | | | | | | | | | | | | | | | | | | | | | There are multiple setup and shutdown functions for Intel device and the setup function to be used is depends on the USB PID/VID, which makes difficult to maintain the code and increases the code size. This patch adds combined setup and shutdown functions to provide a single entry point for all Intel devices and choose the setup functions based on the information read with HCI_Intel_Read_Version command. Starting from TyP device, the command and response parameters for HCI_Intel_Read_Version command are changed even though OCF remains same. However, the legacy devices still can handle the command without error even if it has a extra parameter, so to simplify the flow, the new command format is used to read the version information for both legacy and new (tlv based) format. Also, it also adds a routine to setup the hdev callbacks in btintel. Signed-off-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
