Those patches need to go upstream so we can include fixes, we won't
pick changes which are not going to land upsteam. For the second patch
it is 75604e9a5b60 ("pwm: loongson: Fix LOONGSON_PWM_FREQ_DEFAULT")
which landed in 6.18-rc1 and backported to 6.17.3 as well.
But I do not see the former one. What is the status of that?
Regards,
Salvatore
