From 3fdd94e2bfa3a05a9a1ef7c49c7dccb10ebafdfb Mon Sep 17 00:00:00 2001 From: Daniel Scally Date: Tue, 23 Nov 2021 01:00:16 +0100 Subject: [PATCH] media: i2c: Fix max gain in ov8865 The maximum gain figure in the v4l2 ctrl is wrong. The field is 12 bits wide, which is where the 8191 figure comes from, but the datasheet is specific that maximum gain is 16x (the low seven bits are fractional, so 16x gain is 2048) Signed-off-by: Daniel Scally Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab --- drivers/media/i2c/ov8865.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/i2c/ov8865.c b/drivers/media/i2c/ov8865.c index 1aa577dba0a3..ebdb20d3fe9d 100644 --- a/drivers/media/i2c/ov8865.c +++ b/drivers/media/i2c/ov8865.c @@ -2535,7 +2535,7 @@ static int ov8865_ctrls_init(struct ov8865_sensor *sensor) /* Gain */ - v4l2_ctrl_new_std(handler, ops, V4L2_CID_ANALOGUE_GAIN, 128, 8191, 128, + v4l2_ctrl_new_std(handler, ops, V4L2_CID_ANALOGUE_GAIN, 128, 2048, 128, 128); /* White Balance */
