Patch 1/6 adds support for 2 or 4 lane operation modes. Patch 2/6 call the V4L2 fwnode device parser to handle controls that are standardised by the framework. Patch 3/6 introduces the use of CCI for registers access. Patch 4/6 uses decimal values for sizes registers (instead of hexadecimal). This improves overall readability Patch 5/6 fixes the height value discrepency. Accessible height is 1944, as per the data sheet Patch 6/6 fixes the max analogue gain value. Changes in v5: - Simplify error handling in 2/6. Check for ctrl_hdlr->error - Space fix around { } in 3/6. Drop /* undocumented * as well Changes in v4: - Do not change from window cropping mode in patch 4/6. In v3, the sensor was changed to all pixel scan mode to achieve height=1944, but it can be achieved in window cropping mode as well, by fixing the mode registers changes in v3: - fix patch 2/6 where we need to free ctrl handler on error path. changes in v2: - New patch 4/6 - Drop calculating the pixel clock from link freq. - CCI register address sort (incremental) - Fix cci_write for REG_HOLD handling and add a comment. - Remove unused macros as part of 3/6 Kieran Bingham (2): media: imx335: Support 2 or 4 lane operation modes media: imx335: Parse fwnode properties Umang Jain (4): media: imx335: Use V4L2 CCI for accessing sensor registers media: imx335: Use integer values for size registers media: imx335: Fix active area height discrepency media: imx335: Limit analogue gain value drivers/media/i2c/Kconfig | 1 + drivers/media/i2c/imx335.c | 634 ++++++++++++++++++------------------- 2 files changed, 301 insertions(+), 334 deletions(-)
