How about staying consistent with the sc8280xp which is the closest
platform to sa8775p and do a group for atest_char, a separate group
for atest_usb2...

... and have these as qdss_cti and qdss_gpio.

I think Prasad and Yadu (the original authors of the driver) followed
the example from sc8280xp:
c0e4c71a9e7ce (Bjorn Andersson 2022-03-08 14:11:32 -0800 1804) [156] =
PINGROUP(156, qup6, emac0_ptp, emac0_ptp, _, _, _, _),
Do you remember what your original intention was? I also see that the
GPIOs repeat in the groups definitions:
980 static const char * const emac0_ptp_groups[] = {
981 "gpio130", "gpio130", "gpio131", "gpio131", "gpio156", "gpio156",
982 "gpio157", "gpio157", "gpio158", "gpio158", "gpio159", "gpio159",
983 };
