Fixing it an re-applying the v1 patch that adds the correct delays to the power-up sequence fixes all the ov10640 sporadic initialization errors \o/ Details in the commit message - rdacm21: Increase OV490 firmware boot timeout. Details in the commit message. - media: Propose de-depreaction of subdev init() core operation - Squash max9286 and rdacm20/21 initialization sequence rework to maintain bisectability as suggestd by Kieran and Laurent - Drop i2c speed adjustment as it seems not to have any impact on reliability Run more than 300 boot tests on the in-development version of the series. The previous iteration fixed the failure rate down to 13% from the 25% of the current mainline version. This new iteration on which I run 80 boot tests gave me a single failure when tested with RDACM21 and R8A77970 Eagle board \o/ Thanks j Jacopo Mondi (18): media: i2c: rdamc21: Fix warning on u8 cast media: i2c: rdacm20: Enable noise immunity media: i2c: rdacm20: Embedded 'serializer' field media: i2c: rdacm20: Replace goto with a loop media: i2c: rdacm20: Report camera module name media: i2c: max9271: Check max9271_write() return media: i2c: rdacm20: Check return values media: i2c: rdacm20: Re-work ov10635 reset media: i2c: max9271: Introduce wake_up() function media: i2c: max9286: Adjust parameters indent media: i2c: rdacm21: Fix OV10640 powerdown media: i2c: rdacm21: Give more time to OV490 to boot media: i2c: max9286: Rename reverse_channel_mv media: i2c: max9286: Cache channel amplitude media: i2c: max9286: Define high channel amplitude media: v4l2-subdev: De-deprecate init() subdev op media: gmsl: Reimplement initialization sequence media: i2c: max9286: Rework comments in .bound() drivers/media/i2c/max9271.c | 37 +++++++-- drivers/media/i2c/max9271.h | 9 ++ drivers/media/i2c/max9286.c | 61 ++++++++------ drivers/media/i2c/rdacm20.c | 160 ++++++++++++++++++++---------------- drivers/media/i2c/rdacm21.c | 74 ++++++++++------- include/media/v4l2-subdev.h | 15 +++- 6 files changed, 223 insertions(+), 133 deletions(-) -- 2.30.0
