From 9f9c907fdc331fc6062d758f46f65cb0d2dd11be Mon Sep 17 00:00:00 2001 From: Marcin Rudowski Date: Sun, 12 Mar 2006 00:03:47 -0300 Subject: [PATCH] V4L/DVB (3449): Cx88 default picture controls values This patch fixes default values for some picture controls: - brightness set to 50% by default (now is 0%) - hue set to 50% by default (now is 0%) - sets saturation to datasheet value - volume set to 0dB (now is -32dB) and some left small fixes: - twice offset adding - balance didn't follow datasheet (bits[0:5] = attenuation; bit[6] = channel to provide attenuation) Signed-off-by: Marcin Rudowski Signed-off-by: Ian Pickworth Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/cx88/cx88-video.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/drivers/media/video/cx88/cx88-video.c b/drivers/media/video/cx88/cx88-video.c index 7bbc81fb43b5..b1892dff0fe8 100644 --- a/drivers/media/video/cx88/cx88-video.c +++ b/drivers/media/video/cx88/cx88-video.c @@ -227,7 +227,7 @@ static struct cx88_ctrl cx8800_ctls[] = { .minimum = 0x00, .maximum = 0xff, .step = 1, - .default_value = 0, + .default_value = 0x7f, .type = V4L2_CTRL_TYPE_INTEGER, }, .off = 128, @@ -255,7 +255,7 @@ static struct cx88_ctrl cx8800_ctls[] = { .minimum = 0, .maximum = 0xff, .step = 1, - .default_value = 0, + .default_value = 0x7f, .type = V4L2_CTRL_TYPE_INTEGER, }, .off = 128, @@ -300,7 +300,7 @@ static struct cx88_ctrl cx8800_ctls[] = { .minimum = 0, .maximum = 0x3f, .step = 1, - .default_value = 0x1f, + .default_value = 0x3f, .type = V4L2_CTRL_TYPE_INTEGER, }, .reg = AUD_VOL_CTL, @@ -909,7 +909,8 @@ static int get_control(struct cx88_core *core, struct v4l2_control *ctl) value = c->sreg ? cx_sread(c->sreg) : cx_read(c->reg); switch (ctl->id) { case V4L2_CID_AUDIO_BALANCE: - ctl->value = (value & 0x40) ?
