21 config SERIAL_AMBA_PL010
22 tristate "ARM AMBA PL010 serial port support"
26 This selects the ARM(R) AMBA(R) PrimeCell PL010 UART. If you have
27 an Integrator/AP or Integrator/PP2 platform, or if you have a
28 Cirrus Logic EP93xx CPU, say Y or M here.
32 config SERIAL_AMBA_PL010_CONSOLE
33 bool "Support for console on AMBA serial port"

39 messages and warnings and which allows logins in single user mode).
41 Even if you say Y here, the currently visible framebuffer console
42 (/dev/tty0) will still be used as the system console by default, but

77 bool "Early console using ARM semihosting"
78 depends on ARM64 || ARM
80 select SERIAL_CORE_CONSOLE
81 select SERIAL_EARLYCON
83 Support for early debug console using ARM semihosting. This enables
84 the console before standard serial driver is probed. This is enabled
85 with "earlycon=smh" on the kernel command line. The console is
86 enabled when early_param is processed.

93 select SERIAL_EARLYCON
95 Support for early debug console using RISC-V SBI. This enables

98 enabled when early_param is processed.
100 config SERIAL_SB1250_DUART
101 tristate "BCM1xxx on-chip DUART serial support"
102 depends on SIBYTE_SB1xxx_SOC=y
106 Support for the asynchronous serial interface (DUART) included in
107 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
108 the letter D in DUART stands for "dual", which is how the device
109 is implemented. Depending on the SOC configuration there may be
110 one or more DUARTs available of which all are handled.
112 If unsure, say Y. To compile this driver as a module, choose M here:
113 the module will be called sb1250-duart.

117 depends on SERIAL_SB1250_DUART=y

140 depends on SERIAL_ATMEL=y
141 select SERIAL_CORE_CONSOLE
143 Say Y here if you wish to use an on-chip UART on a Atmel
144 AT91 processor as the system console (the system
145 console is the device which receives all kernel messages and
146 warnings and which allows logins in single user mode).
148 config SERIAL_ATMEL_PDC
149 bool "Support DMA transfers on AT91 serial port"
150 depends on SERIAL_ATMEL
153 Say Y here if you wish to use the PDC to do DMA transfers to
154 and from the Atmel AT91 serial port. In order to
155 actually use DMA transfers, make sure that the use_dma_tx
156 and use_dma_rx members in the atmel_uart_data struct is set
157 appropriately for each port.
159 Note that break and error handling currently doesn't work
160 properly when DMA is enabled. Make sure that ports where
161 this matters don't use DMA.
163 config SERIAL_ATMEL_TTYAT
164 bool "Install as device ttyATn instead of ttySn"
165 depends on SERIAL_ATMEL=y
167 Say Y here if you wish to have the internal AT91 UARTs
168 appear as /dev/ttyATn (major 204, minor starting at 154)
169 instead of the normal /dev/ttySn (major 4, minor starting at
170 64). This is necessary if you also want other UARTs, such as
171 external 8250/16C550 compatible UARTs.
172 The ttySn nodes are legally reserved for the 8250 serial driver
173 but are often misused by other serial drivers.
175 To use this, you should create suitable ttyATn device nodes in
176 /dev/, and pass "console=ttyATn" to the kernel.
178 Say Y if you have an external 8250/16C550 UART. If unsure, say N.
180 config SERIAL_KGDB_NMI
181 bool "Serial console over KGDB NMI debugger port"
182 depends on KGDB_SERIAL_CONSOLE
184 This special driver allows you to temporary use NMI debugger port
185 as a normal console (assuming that the port is attached to KGDB).
187 Unlike KDB's disable_nmi command, with this driver you are always
188 able to go back to the debugger using KGDB escape sequence ($3#33).
189 This is because this console driver processes the input in NMI
190 context, and thus is able to intercept the magic sequence.
192 Note that since the console interprets input and uses polling
193 communication methods, for things like PPP you still must fully
194 detach debugger port from the KGDB NMI (i.e. disable_nmi), and
200 bool "Micrel KS8695 (Centaur) serial port support"
201 depends on ARCH_KS8695

333 providing /dev/ttyTHS0, 1, 2, 3 and 4 (note, some machines may not

336 and better performance.
