Drop it.

CONFIGURATION OPTIONS/SETTINGS ---------------------------------- - -1.1 Configuration of MC13783 SPI bus ------------------------------------- - The power management companion chip MC13783 is connected to the - i.MX31 via an SPI bus. Use the following configuration options - to setup the bus and chip select used for a particular board. - - CONFIG_MC13783_SPI_BUS -- defines the SPI bus the MC13783 is connected to. - Note that 0 is CSPI1, 1 is CSPI2 and 2 is CSPI3. - CONFIG_MC13783_SPI_CS -- define the chip select the MC13783 s connected to. - -1.2 Timer precision -------------------- - CONFIG_MX31_TIMER_HIGH_PRECISION - - Enable higher precision timer. The low-precision timer - (default) provides approximately 4% error, whereas the - high-precision timer is about 0.4% accurate. The extra - accuracy is achieved at the cost of higher computational - overhead, which, in places where time is measured, should - not be critical, so, it should be safe to enable this - option.
