Hi.
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 (5):
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
misc: rtsx_usb: / memstick: rtsx_usb_ms: Avoid long delay before
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.
