This series contains few patches resulting from the notes I
took while reviewing Mark ADB series last Sunday, in particular:
https://www.mail-archive.com/qemu-devel@nongnu.org/msg712078.html

I have another patch for hw/input/hid.c but I prefer to hold it
to test it more.

Philippe Mathieu-Daudé (7):
  qemu-common: Briefly document qemu_timedate_diff() unit
  block/qcow2: Document cache_clean_interval field holds seconds
  block/curl: Reduce timer precision to milli-second
  hw/virtio/virtio-balloon: Rename timer field including 'ms' unit
  hw/rtc/m48t59: Reduce timer precision to milli-second
  hw/ipmi/ipmi_bmc_extern: Reduce timer precision to milli-second
  hw/watchdog/wdt_aspeed: Reduce timer precision to micro-second
