Hi Dmitry Baryshkov,
Thanks for the series.
Looks like, After this patch, when I change resolution using modetest it is not
working.
Monitor is showing out of range/No signal on RZ/V2L SMARC EVK connected to
ADV7535.
Not sure, I am the only one facing this issue?
Modetest works fine with 6.15

The host_node pointer assigned and freed in adv7533_parse_dt()
and later adv7533_attach_dsi() uses the same. Fix this issue
by freeing the host_node in adv7533_attach_dsi() instead of
adv7533_parse_dt().
