This is much better than before, but there is still a way to go.

Add the vpuapi layer of the wave5 codec driver.
This layer is used to configure the hardware according
to the parameters.

This cast is just to get rid of the const. "code" here is a uint16_t
pointer but in wave5_vpu_re_init() it's a u8 pointer. I think it should
be const u8 everywhere.
Also use u8/u16 types instead of uint8/16_t unless it's something that's
shared with user space.

Could you explain when should an iterator be size_t and when should it be u64 ?
encourages bad iterator types and it regularly causes kernel bugs. GCC
is sometimes wrong headed.

These are badly aligned and contribute to the Wall of Text Effect that
this code has. :(
vpu_write_reg(vpu_inst->dev, W5_COMMAND_OPTION,
(option->disable_film_grain << 6) |
(option->cra_as_bla_flag << 5) |
mode_option);
+ vpu_write_reg(vpu_inst->dev, W5_CMD_DEC_TEMPORAL_ID_PLUS1,

vpu_write_reg(vpu_inst->dev, W5_CMD_DEC_TEMPORAL_ID_PLUS1,
((p_dec_info->target_spatial_id + 1) << 9) |
(p_dec_info->temp_id_select_mode << 8) |
(p_dec_info->target_temp_id + 1));
Why do we have to add "+ 1" to p_dec_info->target_spatial_id?
for some reason the code defines 'DECODE_ALL_SPATIAL_LAYERS' to -1 and then adding '+ 1' set it to 0
no idea why is it implemented like that.

vpu_write_reg(vpu_inst->dev, W5_CMD_DEC_FORCE_FB_LATENCY_PLUS1, force_latency);
is it nice to write bool to a reigeter?, isn't it better to set 'force_latency' to u32?

Okay, I have to go. I have run out of time for reviewing this code.
It's much better but there is still a way to go.
Thanks for the review, indeed long way to go.
