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.

* kinetis:PIT add Liftime and Chaining
* kinetis:flexcan fix dup line and ordering
* kinetis:kinetis_lowput.c LPUART data format with parity fix
The 9-bit data mode is typically used with parity to allow
eight bits of data plus the parity
* kinetis:pindma fix warning
* kinetis:lowputc LPUART_BAUD_INIT has to be defined
build fails with test case enable LPUART0 and make
UART1 console
if HAVE_LPUART_DEVICE is defined then LPUART_BAUD_INIT
has to be defined even if the lpuart is not the console
* kinetis:lpserial fix warning
While this is a good idea and a proper thing to do, it also creates a circular dependency and errors during configuration. RTC depends on STM32_RTC which depends on RTC_EXTERNAL with depends on RTC. No can do.
This reverts commit 714e8c1f9e.
