      tty/serial: Add explicit PORT_TEGRA type · 4539c24f
      Stephen Warren 提交于
      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.

      8250_pci: Add support for the Digi/IBM PCIe 2-port Adapter · aa273ae5
      Scott Kilau 提交于
      Add support to the 8250 PCI serial driver for the Digi/IBM PCIe 2-port Async EIA-232 Adapter.
      
      Oxford Semiconductor produces a 2/4/8 port UART (OXPCIe952/OXPCIe954/OXPCIe958) chip
      called the Tornado, that can be used to create a very simple serial board product.
      The kernel sources currently have just 2 vendors using this chip, which is Oxford and Mainpipe.
      This new Digi/IBM serial product now uses it as well.
      
      Rather than create a long running comment of vendors using the chip, the one changed comment
      in the patch below now just lists "For Oxford Semiconductor Tornado based devices" to be a
      more generic comment for all vendors that end up using the Oxford Tornado chip.

      ASoC: Update cx20442 for TTY API change · ed0bd233
      Mark Brown 提交于
      receive_buf() was recently changed to return the number of bytes
      received but the cx20442 driver wasn't updated to match the new API.
      I don't have any hardware but since we don't actually appears to be
      listening to the data at all just report that we accepted all the data
      that was offered to us.
