Memory leak happens in the following function __drm_atomic_helper_connector_reset(), where newly allocated asyc->state will be assigned to connector->state. So using nouveau_conn_atomic_destroy_state() instead of __drm_atomic_helper_connector_destroy_state to free the "old" asyc.

Since these scripts are executed before initializing any subdevices, we end up failing to acquire access to the i2c bus which has left a number of cards with their fan controllers uninitialized. Luckily this doesn't break hardware - it just means the fan gets stuck at 100%. This also means that we've always been using our i2c busses before initializing them during the init scripts for older GPUs, we just didn't notice it until we started preventing them from being used until init. It's pretty impressive this never caused us any issues before! So, fix this by initializing our i2c pad and busses during subdev pre-init. We skip initializing aux busses during pre-init, as those are guaranteed to only ever be used by nouveau for DP aux transactions.

This need provide valid ref clk values. for navi10, since dispcontroller_init is not called, dchubbub_global_timer_enable = 0, hubbub2_get_dchub_ref_freq will hit aeert. this need remove hubbub2_get_dchub_ref_freq from this location and move to dcn20_init_hw. [HOW] for all asic, initialize dccg, dchub ref clk with data from vbios firmware table by default. for raven asic family, use these data from vbios, for asic which support sw dccg component, like navi10, read ref clk by sw dccg functions and update the ref clk.

Set a sound prefetch mode for all VMIDs rather than forcing all shaders to set the prefetch mode at the beginning. Reduce code duplication a bit while we're at it. Note that the 64-bit address mode enum and the retry all enum are both 0, so the only functional change is in the INITIAL_INST_PREFETCH field.

This patch replaces the deprecated simple_strtol() use introduced recently. As clk is of type uint32_t, we are safe to use kstrtou32(). It is also safe to return zero on string parsing error, similar to the case of returning zero if buf is empty in parse_clk().
