Subject: [PATCH v4 0/5] media: i2c: imx214: Add support for more clock frequencies
Date: Sat, 24 May 2025 11:14:35 +0200 [thread overview]
Message-ID: <20250524-imx214_ccs_pll-v4-0-f7dc22e5255b@apitzsch.eu> (raw)
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.
This series supersedes

Changes in v4:
- Add missing colon to error message
- Add A-b, R-b tags
- Link to v3: https://lore.kernel.org/r/20250521-imx214_ccs_pll-v3-0-bfb4a2b53d14@apitzsch.eu
Changes in v3:
- Limit range of pll_ip_clk_freq_hz (Sakari)
- Drop unneeded 'ret'
- Use pll.pixel_rate_csi for bit rate calculation
- Add patch that deprecates the clock-frequency property
- Link to v2: https://lore.kernel.org/r/20250505-imx214_ccs_pll-v2-0-f50452061ff1@apitzsch.eu
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:
