drivers/serial/uart_16550.c: Support 16550 auto hardware flow control

    drivers/serial/uart_16550.c:  Add configuration option CONFIG_16550_SUPRESS_INITIAL_CONFIG.  This is identical to the standard configuration in arch/Kconfig CONFIG_SUPPRESS_UART_CONFIG, but with scope of only the 16550 driver.

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

8394f9b60f Squashed commit of the following: 
configs/z80sim and xtrs:  Serial driver lower halfs ioctl methods should return a negated errno value, not set the errno variable.

    drivers/wireless:  CC1101 driver not permitted to set errno.

    drivers/sensors:  LIS331DL driver not permitted to set errno.

    drivers/lcd: ILI9341 initialize method not permitted to set errno,

    drivers/serial: 16550 UART driver IOCTL method must not set errno; it must return a negated errno value.

b3222bbc8a irq_dispatch: Add argument pointer to irq_dispatch

passed back when the isr is called.

08c001196b drivers/: Remove all explicit use of 'hidden' macro _info. Code must never use this directly. Code must always use a debug macro such as info which is basic on _info but can be appropriately filtered. 2017-01-15 13:00:50 -06:00

2fa6237b49 Revert THRNE-patch. The problem was in u16550_putc 
Regarding to:
https://github.com/tanzilli/ariag25-linux-2.6.39/blob/ariag25/drivers/tty/serial/8250.c#L1584
https://github.com/tanzilli/ariag25-linux-2.6.39/blob/ariag25/drivers/tty/serial/8250.c#L1913

When UART_LSR_THRE bit is set, then we ready to transmit more.

Current u16550_putc loops while UART_LSR_THRE bit is set. This logic have to be inverted.
