2019-11-20rtw88: allows to enable/disable HCI link PS mechanismYan-Hsuan Chuang4-0/+51
Different interfaces have its own link-related power save mechanism. Such as PCI can enter L1 state based on the traffic on the link, and sometimes driver needs to enable/disable it to avoid some issues, like throughput degrade when PCI trying to enter L1 state even if driver is having heavy traffic. For now, rtw88 only supports PCIE chips, and they just need to disable ASPM L1 when driver is not in power save mode, such as IPS and LPS.

2019-11-20rtw88: pci: enable CLKREQ function if host supports itYan-Hsuan Chuang2-0/+85
By Realtek's design, there are two HW modules associated for CLKREQ, one is responsible to follow the PCIE host settings, and another is to actually working on it. But the module that is actually working on it is default disabled, and driver should enable that module if host and device have successfully sync'ed with each other. The module is default disabled because sometimes the host does not support it, and if there is any incorrect settings (ex. CLKREQ# is not Bi-Direction), device can be lost and disconnected to the host. So driver should first check after host and device are sync'ed, and the host does support the function and set it in configuration space, then driver can turn on the HW module to working on it.
