drivers/serial: Add driver for Aspeed virtual UART

2017-03-22T14:57:51+00:00

This change adds a driver for the 16550-based Aspeed virtual UART device. We use a similar process to the of_serial driver for device probe, but expose some VUART-specific functions through sysfs too. If host TX discard mode is enabled, we don't see the LSR[RBR} bit getting set on new characters written on the host side. This makes the VUART a little useless. OpenPOWER firmware doesn't like it when the host-side of the VUART's FIFO is not drained. This change only disables host TX discard mode when the port is in use. We set the VUART enabled bit when we bind to the device, and clear it on unbind. We don't want to do this on open/release, as the host may be using this bit to configure serial output modes, which is independent of whether the devices has been opened by BMC userspace.

serial: rewrite pxa2xx-uart to use 8250_core

2016-10-27T14:03:09+00:00

pxa2xx-uart was a separate uart platform driver. It was declaring the same device names and numbers as 8250 driver. As a result, it was impossible to use 8250 driver on PXA SoCs. Upon closer examination pxa2xx-uart turned out to be a clone of 8250_core driver. Workaround for Erratum #19 according to Marvel(R) PXA270M Processor Specification Update (April 19, 2010) is dropped. 8250_core reads from FIFO immediately after checking DR bit in LSR. The patch leaves the original SERIAL_PXA driver around. The original driver is just marked DEPRECATED in Kconfig and C source. When the original driver is considered safe to remove, no changes to SERIAL_8250 will be necessary. Compiling SERIAL_8250_CONSOLE and SERIAL_PXA_CONSOLE even without SERIAL_8250_PXA breaks console for SERIAL_PXA. For this reasons, the new and the original drivers are made mutually exclusive.

Enhance the Renesas SCI UART driver to add support for GPIO-controlled modem lines (CTS, DSR, DCD, RNG, RTS, DTR), using the serial_mctrl_gpio helpers. GPIO-controlled modem lines can be used when dedicated modem lines are not available. Invalid configurations specifying both GPIO RTS/CTS and dedicated RTS/CTS are rejected.
