Hi,
This is based on Ulf's work [1] [2].
This patch series can keep rtsx_usb suspended, to save ~0.5W on Intel platforms and ~1.5W on AMD platforms.
[1] https://patchwork.kernel.org/patch/10440583/ [2] https://patchwork.kernel.org/patch/10445725/
Kai-Heng Feng (4): misc: rtsx_usb: Use USB remote wakeup signaling for card insertion detection memstick: Prevent memstick host from getting runtime suspended during card detection memstick: rtsx_usb_ms: Use ms_dev() helper memstick: rtsx_usb_ms: Support runtime power management
v5: Corretly use system suspend/resume and runtime suspend/resume callback. Prevent runtime callbacks get call during system suspend.
v4: Use pm_runtime_put() in memstick_check().
v3: Skip parent device check in rtsx_usb_resume_child(). Remove dev_dbg() if it only prints function name. Use ms_dev() helper at more places. Remove const qualifier for UNIVERSAL_DEV_PM_OPS.
v2: Resend to linux-usb and LKML.
