Hi Josh,

Sorry, I missed the 4.3 merge cycle, but isn't this patch a fix? Isn't it
fixing soc-camera / atmel-isi on a specific platform, where the clock name
is longer, than currently supported? Is this platform in the mainline and
its current camera support is broken because of this?

I missed your email, so sorry for the late reply.

yes, it will break the detect flow if the i2c camera is loaded as module.

In such a case we
could still push it in for 4.3

So it is a fix, it is great if this one can still go into 4.3.

Best Regards,
Josh Wu

Thanks

Since in soc_of_bind() it may use the of node's full name as the clk_name,
and this full name may be longer than 32 characters, take at91 i2c sensor
as an example, length is 34 bytes:
/ahb/apb/i2c@f8028000/camera@0x30

So this patch increase the clk_name[] array size to 64. It seems big
enough so far.
