Actually, seems should be like that:

config I2C_TEGRA_DMA_SUPPORT
	bool "NVIDIA Tegra internal I2C controller DMA support"
	depends on I2C_TEGRA
	depends on (TEGRA20_APB_DMA && ARCH_TEGRA_2x_SOC) || \
		   (TEGRA20_APB_DMA && ARCH_TEGRA_3x_SOC) || \
		   (TEGRA20_APB_DMA && ARCH_TEGRA_114_SOC) || \
		   (TEGRA20_APB_DMA && ARCH_TEGRA_124_SOC) || \
		   (TEGRA20_APB_DMA && ARCH_TEGRA_210_SOC)
	help
	  If you say yes to this option, DMA engine integration support will
	  be included for the I2C controller embedded in NVIDIA Tegra SOCs 

But you got the idea.
