Squashed commit of the following: Author: Gregory Nutt <gnutt@nuttx.org> arch/arm/src/kinetis: Cosmetic changes from review of coding standard. Author: David Sidrane <david_s5@nscdg.com> Merged in david_s5/nuttx/master_kinetis (pull request #710) kinetis:Add DMA and use it as RX FIFOs on Serial * Add initial implementation of the DMA * Add across Kxx family support [WIP] * Incorporate the DMA into the serial Add polling to serial do DMA initialisation at UART startup and fix DMA mux setting. Fix circular DMA handling in the serial driver. * Adapt defconfig to enable UART1,4 RXDMA * [WIP] - refactor this with new CONFIG DMA settings * kinetis/Kconfig:Bring inline with upstream stucture 1. Use the Serial console configuration from drivers/serial/Kconfig and friends. 2. Prefix arch specific featurs as such UARTx_RXDMA->KINETIS_UARTx_RXDMA * Kinetis:Serial formatting and clean up * kinetis:DMA Formating and Cleanup * kinetis:serial Use cleaner DMA API * kinetis:Make.defs fix duplicate/errant kinetis_dma.o * kinetis:serial Fix warning/error on only one uart using DMA The driver can support no DMA on any UART, DMA on some UARTs or DMA on all UARTs. In the case of no DMA we disable the DMA based variables and logic. In the case of all DMA we disable the non DMA variables and logic, and in the mixed case both DMA and non DMA variable and logic are enabled. * kinetis:dma config fix formatting * kinetis:chip/dma fix formatting * kinetis:DMA config assume Unknown Assume KINETIS_DMA_VERSION_UKN for all SoC not versioned This is as the code was in nuttx prior to this commit * kinetis:DMAMUX contain versioning- use HAS pattern define Unknown The pattern for chip versioning is to define 'HAS' constants. Define KINETIS_DMAMUX_HAS_MONOTONIC_CHCFG to contain the version numbers to the include soc header and use that define in the chip headers. Define the KINETIS_DMAMUX_VERSION_UKN for the default as prior this commit addressing was by default monotonic for CHCFG * freedom-k66f:Disable Serial RXDMA The application has to add calling of the kinetis serial dma poll as it is application specific.
