[PATCH v2 0/4] media: i2c: imx214: Add support for more clock frequencies

["André Apitzsch via B4 Relay" <devnull+git.apitzsch.eu@kernel.org>]

The imx214 driver currently supports only a 24 MHz external clock. But
there are devices, like Qualcomm-MSM8916-based phones, which cannot
provide this frequency. To make the sensor usable by those devices, add
support for additional clock frequencies.

Changes in v2:
- Add A-b tags
- Switch to v4l2_ctrl_s_ctrl_int64() to acquire the control handler mutex
- Add error handling for v4l2_ctrl_s_ctrl_int64() and
  imx214_pll_update()
- Replace "read clock frequency from dt" patch by "remove hard-coded
  external clock frequency" patch
- Link to v1:
