Those values are controlled by the values of RSET and CT elements attached to the controller. Those values should be conveyed via Device Tree, and the LED device API should reflect that accordingly. The question is whether it is worth a hassle to add support for this older chipset version.

S2C allows setting brightness level perfectly fine, I have tested it on my LG Optimus 2X P990 (star) that has this LED flash driver. Flash timeout is fixed, that is true, but both AAT1270 and AAT1290 feature mandatory flash inhibit logic which is not implemented by this driver and can be used to set emergency flash disable. > Those values should be conveyed > via Device Tree, and the LED device API should reflect that accordingly. > They are calculated same way as AAT1290 does and set in the device tree.
