k_po/k_pu are two proportional term constants and essentially they have fixed ratio compared with sustainable power. In current implementation, k_po and k_pu are absolute value after calculation and cannot represent the ratio relationship with sustainable power; as a result, when change sustainable power we cannot smoothly change proportional term constant.
So this patch series introduces k_po_ratio and k_pu_ratio, which represent the ratio value compared against sustainable power. Also add sys file system nodes for them for easily update them from userspace and update a bit in documentation.
Changes from v1: * According to Eduardo' comments, move code from thermal_core to power_allocator file * According to Daniel's review, v1 will introduce accumulated rounding errors; v2 patches can dismiss this issue
Leo Yan (4): thermal: power_allocator: rework proportional parameter thermal: power_allocator: change k_pu_ratio/k_po_ratio as percentage thermal: add sys node for k_pu_ratio/k_po_ratio thermal: power_allocator: document k_pu_ratio/k_po_ratio
