Tc358743 9-000f: failed to get refclk: -2

user74491 · November 26, 2024, 3:03am

[ 11.771315] tc358743 9-000f: failed to get refclk: -2
[ 11.771321] tc358743: probe of 9-000f failed with error -2
[ 11.771356] tc358743 10-000f: failed to get refclk: -2
[ 11.771359] tc358743: probe of 10-000f failed with error -2
Im trying to port tc358743 camera drive on r36.4.
When I boot up the probe fails in my probe_of function with the error “failed to get refclk: -2”.
The code below fails.

tc358743.c

refclk = devm_clk_get(dev, "refclk");
if (IS_ERR(refclk)) {
	if (PTR_ERR(refclk) != -EPROBE_DEFER)
		dev_err(dev, "failed to get refclk: %ld\n",
			PTR_ERR(refclk));
	return PTR_ERR(refclk);
}

I gave refclk in device tree related code but still got error.

Confirm the refclk by checking /proc/device-tree/…

user74491 · November 26, 2024, 7:07am

What does ‘Confirm the refclk by checking /proc/device-tree/’ mean?
I did check the path.
test@test-desktop:/proc/device-tree$ grep -r refclk
grep: bus@0/cam_i2cmux/i2c@0/toshiba_tc358743_a@0f/clock-names: binary file matches
grep: bus@0/cam_i2cmux/i2c@1/toshiba_tc358743_c@0f/clock-names: binary file matches
test@test-desktop:/proc/device-tree$ cat bus@0/cam_i2cmux/i2c@0/toshiba_tc358743_a@0f/clock-names
refclk

ShaneCCC · November 26, 2024, 7:21am

Looks like Orin don’t have refclk. You need to check the HW connect to which clock source from Orin Nano to redefine it.

I fixed it like this but still have the same problem.

Could you explain the what is the problem?

What’s the refclk connect to? If there’s no need you can remove it from the driver.

user74491 · November 28, 2024, 4:58am

This is clk in the tc358743_probe_of function.
static int tc358743_probe_of(struct tc358743_state *state)
{
…
struct clk *refclk;
u32 bps_pr_lane;
int ret;

refclk = devm_clk_get(dev, "refclk");
if (IS_ERR(refclk)) {
	if (PTR_ERR(refclk) != -EPROBE_DEFER)
		dev_err(dev, "failed to get refclk: %ld\n",
			PTR_ERR(refclk));
	return PTR_ERR(refclk);
}

ep = of_graph_get_next_endpoint(dev->of_node, NULL);
if (!ep) {
	dev_err(dev, "missing endpoint node\n");
	return -EINVAL;
}

…
}
If i block clk, an error will occur right after ‘missing endpoint node’.
