Thanks, Pavel! :-) Besides this patch, what else is needed? The CSI-2 / CCP2 support is missing in V4L2 OF at least. It'd be better to have this all in the same set.
I pushed the two DT patches here: <URL:https://git.linuxtv.org/sailus/media_tree.git/commit/?h=ccp2> On Wed, Feb 08, 2017 at 02:11:27PM +0100, Pavel Machek wrote: > > Add support for CCP2 connected SMIA sensors as found > on the Nokia N900. > > Signed-off-by: Sebastian Reichel <s...@kernel.org> > Signed-off-by: Ivaylo Dimitrov <ivo.g.dimitrov...@gmail.com> > Signed-off-by: Pavel Machek <pa...@ucw.cz> > > diff --git a/drivers/media/i2c/smiapp/smiapp-core.c > b/drivers/media/i2c/smiapp/smiapp-core.c > index 44f8c7e..c217bc6 100644 > --- a/drivers/media/i2c/smiapp/smiapp-core.c > +++ b/drivers/media/i2c/smiapp/smiapp-core.c > @@ -2997,13 +2997,19 @@ static struct smiapp_hwconfig > *smiapp_get_hwconfig(struct device *dev) > switch (bus_cfg->bus_type) { > case V4L2_MBUS_CSI2: > hwcfg->csi_signalling_mode = SMIAPP_CSI_SIGNALLING_MODE_CSI2; > + hwcfg->lanes = bus_cfg->bus.mipi_csi2.num_data_lanes; > + break; > + case V4L2_MBUS_CCP2: > + hwcfg->csi_signalling_mode = (bus_cfg->bus.mipi_csi1.strobe) ? > + SMIAPP_CSI_SIGNALLING_MODE_CCP2_DATA_STROBE : > + SMIAPP_CSI_SIGNALLING_MODE_CCP2_DATA_CLOCK; > + hwcfg->lanes = 1; > break; > - /* FIXME: add CCP2 support. */ > default: > + dev_err(dev, "unknown bus protocol\n"); It's rather unsupported --- V4L2 OF framework picks one from enum v4l2_mbus_type.
