I agree with petri on having explicit {}. All the other macros are
following that, e.g.: igt_subtest.

#define connector_subtest_start(name__, type__)              \
       igt_subtest_with_dynamic(name__)                     \
               for_each_port(p, port)                       \
                       if (chamelium_port_get_type(port) == \
                           DRM_MODE_CONNECTOR_ ## type__)


connector_subtest_start("hdmi-rgb-pixel-format", HDMIA) {
 /* ... */
}

you are dropping few thing from the titles, especially information that
this is chamelium CRC tests

how about naming them:
  hdmi-crc-nonplanar-formats instead of rgb
  hdmi-crc-planar-formats instead of yuv

and then having the dunamic subsubtests named after the format alone, so
the end result would be like this:

igt at kms_chamelium@hdmi-crc-nonplanar-formats at rgb888

other than that looks good to me, thanks! :-)
