  • 4539c24fe   tty/serial: Add explicit PORT_TEGRA type ... Browse Code »
    1

    Tegra's UART is currently auto-detected as PORT_XSCALE due to register
    bit UART_IER.UUE being writable. However, the Tegra documentation states
    that this register bit is reserved. Hence, we should not program it.

    Instead, the documentation specifies that the UART is 16550 compatible.
    However, Tegra does need register bit UART_IER.RTOIE set, which is not
    enabled by any 16550 port type. This was not noticed before, since
    PORT_XSCALE enables CAP_UUE, which conflates both UUE and RTOIE bit
    programming.

    This change defines PORT_TEGRA that doesn't set UART_CAP_UUE, but does
    set UART_CAP_RTOIE, which is a new capability indicating that the RTOIE
    bit needs to be enabled.

  • a3ae0fc34   8250: add a UPIO_DWAPB32 for 32 bit accesses ... Browse Code »

    Some platforms contain a Synopsys DesignWare APB UART that is attached
    to a 32-bit APB bus where sub-word accesses are not allowed. Add a new
    IO type (UPIO_DWAPB32) that performs 32 bit acccesses to the UART.

    v2:
    - don't test for 32 bit in the output fast path, provide a
    separate dwabp32_serial_out() function. Refactor
    dwabp_serial_out() so that we can reuse the LCR saving
    code.
    v3:
    - rebased on top of "8250: use container_of() instead of
    casting"

  • 304e12665   serial: Add support for UART on VIA VT8500 and compatibles ... Browse Code »

    This adds a driver for the serial ports found in VIA and WonderMedia
    Systems-on-Chip. Interrupt-driven FIFO operation is implemented.
    The hardware also supports pure register-based operation (which is
    slower) and DMA-based FIFO operation. As the FIFOs are only 16 bytes
    long, DMA operation is probably not worth the hassle.

  • b612633b5   serial: Add OMAP high-speed UART driver ... Browse Code »

    This patch adds driver support for OMAP2/3/4 high speed UART.

    The driver is made separate from 8250 driver as we cannot
    over load 8250 driver with omap platform specific configuration for
    features like DMA, it makes easier to implement features like DMA and
    hardware flow control and software flow control configuration with
    this driver as required for the omap-platform.
    This patch involves only the core driver and its dependent.

  • d843fc6e9   hsu: driver for Medfield High Speed UART device ... Browse Code »

    This is a PCI & UART driver, which suppors both PIO and DMA mode
    UART operation. It has 3 identical UART ports and one internal
    DMA controller.

    Current FW will export 4 pci devices for hsu: 3 uart ports and 1
    dma controller, each has one IRQ line. And we need to discuss the
    device model, one PCI device covering whole HSU should be a better
    model, but there is a problem of how to export the 4 IRQs info

    Current driver set the highest baud rate to 2746800bps, which is
    easy to scale down to 115200/230400.... To suport higher baud rate,
    we need add special process, change DLAB/DLH/PS/DIV/MUL registers
    all together.

    921600 is the highest baud rate that has been tested with Bluetooth
    modem connected to HSU port 0. Will test more when there is right
    BT firmware.

    Current version contains several work around for A0's Silicon bugs

  • f5316b4ae   kgdb,8250,pl011: Return immediately from console poll ... Browse Code »

    The design of the kdb shell requires that every device that can
    provide input to kdb have a polling routine that exits immediately if
    there is no character available. This is required in order to get the
    page scrolling mechanism working.

    Changing the kernel debugger I/O API to require all polling character
    routines to exit immediately if there is no data allows the kernel
    debugger to process multiple input channels.

    NO_POLL_CHAR will be the return code to the polling routine when ever
    there is no character available.
