Looking at the CCM_CCGR0 register (address: 20C_4068) there is no
aips_tz3 clock gate in bits 31-30.
Bits 31-30 are gpio2_clocks and Anson has recently sent a patch adding
support for it:
https://patchwork.kernel.org/patch/10481351/
Please test Anson's patch as it should fix the problem you had.

Fabio Estevam
