Subject: [PATCH v2 0/4] uvcvideo: Fix handling of power_line_frequency

The uvc 1.5 standard recognizes 4 different values for this control, but we
were only using the first 3.

Also add a quirk for those devices that only support 50 and 60 Hz.

v2: Thanks Laurent! 

Do not modify the behaviour of v1.1

Ricardo Ribalda (4):
  media: uvcvideo: Add missing value for power_line_frequency
  media: uvcvideo: Add UVC_QUIRK_LIMITED_POWERLINE
  media: uvcvideo: Add LIMITED_POWERLINE quirks for Quanta UVC Webcam
  media: uvcvideo: Add LIMITED_POWERLINE quirks for Chicony Easycamera
