Xiang Xiao 46e47c8dcf Squashed commit of the following: 
drivers/serial/uart_16550.c:  Add a configuration, analogous to the STM32 configuration option, to suppress the NuttX standard re-ordering for /dev/ttySN for special case of the 16550 UART.

    config/serial: UART 16550: Add CONFIG_SERIAL_UART_ARCH_MMIO option so the a memory mapped device doesn't need to provide uart_getreg() and uart_putreg() implementations.

    u16550_txempty() should check UART_LSR_TEMT to avoid some data left in the transmit FIFO

Kconfig drivers/serial/Kconfig: Make feature dependent on CONFIG_BUILD_FLAT. 2018-08-26 08:56:16 -06:00
Kconfig-16550 Squashed commit of the following: 2018-08-26 11:17:33 -06:00
Kconfig-lpuart drivers/serial/Kconfig: Kconfig is too big, divide into Kconfig, Kconfig-uart, Kconfig-usart, Kconfig-sci, Kconfig-16550. More than one MCU supports LPUARTs. Add Kconfig-lpuart and remove MCU-specific LPUART definitions. Affects Kinetis and STM32L4. 2018-03-14 10:33:27 -06:00
Kconfig-sci drivers/serial/Kconfig: Kconfig is too big, divide into Kconfig, Kconfig-uart, Kconfig-usart, Kconfig-sci, Kconfig-16550. More than one MCU supports LPUARTs. Add Kconfig-lpuart and remove MCU-specific LPUART definitions. Affects Kinetis and STM32L4. 2018-03-14 10:33:27 -06:00

lowconsole.c Silence some warnings 2016-05-26 14:06:13 -04:00
Make.defs drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C library. But there is a problem. The specification of tcdrain() requires that it be a cancellation point. In order to do this, tcdrain was moved from the C library into the OS and the addition cancellation point hooks were added. In non-FLAT builds, access via system calls is also now supported. 2017-10-06 10:55:36 -06:00
ptmx.c Squashed commit of the following: 2017-10-04 15:22:27 -06:00
pty.c drivers/serial/pty.c: Add support so that a PTY can poll for both IN/OUT event simultaneously. 2018-08-26 07:27:19 -06:00
pty.h PTY: Add ioctls to support locking and unlocking of the slave. LIBC: Add implementation of unlockpt() 2016-07-15 09:39:33 -06:00
serial.c drivers/serial/serial.c: In DMA mode, the use of uart_disablexinit() is insufficient to protect a critical section. enter/leave_critical_section() must be used in those cases if CONFIG_SERIAL_DMA=y 2018-08-26 10:30:48 -06:00
serial_dma.c drivers/serial: Move head/tail pointer reset to uart_recvchars_dma since dma may be still transferring in the background. 2018-08-26 10:03:30 -06:00
serial_io.c Squashed commit of the following: 2018-08-26 08:49:08 -06:00
tcdrain.c Make sure that labeling is used consistently in all function headers (part 2). 2018-02-01 12:03:55 -06:00
