All MSM SoCs have a TLMM block. The block itself carries no model or revision name, and is not tied specifically to any particular SoC, except for the fact that the second generation of this block happened to appear at the same time as the MSM8x60. gpio.c is already in wide use for v1 systems, and is well-establised in the android mainlines. Changing without extremely good cause would not go pleasantly. Since gpio.c is v1, we used gpio-v2.c for v2. -- Employee of Qualcomm Innovation Center, Inc.
