Rob, Mauro, media subsystem reviewers, This is the 6th version of my On Semi AR0521 sensor driver. The documentation patch (1/2) hasn't been changed from v4: onnn,ar0521.yaml | 112 1 file changed, 112 insertions(+) The actual driver (2/2) changes: MAINTAINERS | 7 drivers/media/i2c/Kconfig | 13 drivers/media/i2c/Makefile | 1 drivers/media/i2c/ar0521.c | 1051 4 files changed, 1072 insertions(+) - I reformatted the code to fit in 80 columns. Nobody should be asked to make his code worse (and the 80-column version IS worse), and multiple high-profile Linux developers (including the top one) appear to share my opinion, but nevertheless - if it's something that will make it go in, I won't care. - Basically the same applies to the // comments. - I have removed the "interval" support (frames per second). Unfortunately this cripples the driver further a bit - the userspace will not be able to set precise frame timings needed for broadcast quality video. I will have to keep a private patch for that. Another effect of this change is that the pixel clock is now fixed at 184 MHz, which by default produces ca. 30 FPS at 2560x1920. This may be problematic on systems with less than 4 MIPI lanes, and/or on ones which can't support higher frequency MIPI bus (the previous version used a calculated clock). Perhaps it will be possible to fix this issue in the future, with a couple of core V4L2 changes. - the driver now provides the .pre_streamon() for setting LP-11 state on MIPI data and clock lanes. This is compatible with i.MX6 receiver. - s_power() converted to SET_RUNTIME_PM_OPS(). - the "initial" I2C registers have been all converted to a table of multi-register files, to minimize time spent on I2C bus. - a lot of smaller changes suggested by Laurent, Sakari, Jacopo and possibly others. -- Krzysztof "Chris" Hałasa Sieć Badawcza Łukasiewicz Przemysłowy Instytut Automatyki i Pomiarów PIAP Al.
