10 config SERIAL_EARLYCON
12 depends on SERIAL_CORE
14 Support for early consoles with the earlycon parameter. This enables
15 the console before standard serial driver is probed. The console is
16 enabled when early_param is processed.

20 comment "Non-8250 serial port support"
22 config SERIAL_AMBA_PL010
23 tristate "ARM AMBA PL010 serial port support"
27 This selects the ARM(R) AMBA(R) PrimeCell PL010 UART. If you have
28 an Integrator/AP or Integrator/PP2 platform, or if you have a
29 Cirrus Logic EP93xx CPU, say Y or M here.
33 config SERIAL_AMBA_PL010_CONSOLE
34 bool "Support for console on AMBA serial port"
35 depends on SERIAL_AMBA_PL010=y
36 select SERIAL_CORE_CONSOLE
38 Say Y here if you wish to use an AMBA PrimeCell UART as the system
39 console (the system console is the device which receives all kernel
40 messages and warnings and which allows logins in single user mode).
42 Even if you say Y here, the currently visible framebuffer console
43 (/dev/tty0) will still be used as the system console by default, but
44 you can alter that using a kernel command line option such as
45 "console=ttyAM0". (Try "man bootparam" or see the documentation of
46 your boot loader (lilo or loadlin) about how to pass options to the

61 bool "Support for console on AMBA serial port"
62 depends on SERIAL_AMBA_PL011=y
63 select SERIAL_CORE_CONSOLE

68 messages and warnings and which allows logins in single user mode).
70 Even if you say Y here, the currently visible framebuffer console

78 bool "Early console using ARM semihosting"
79 depends on ARM64 || ARM
81 select SERIAL_CORE_CONSOLE
82 select SERIAL_EARLYCON
84 Support for early debug console using ARM semihosting. This enables
85 the console before standard serial driver is probed. This is enabled
86 with "earlycon=smh" on the kernel command line. The console is
87 enabled when early_param is processed.
89 config SERIAL_SB1250_DUART
90 tristate "BCM1xxx on-chip DUART serial support"
91 depends on SIBYTE_SB1xxx_SOC=y
95 Support for the asynchronous serial interface (DUART) included in
96 the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
97 the letter D in DUART stands for "dual", which is how the device
98 is implemented. Depending on the SOC configuration there may be
99 one or more DUARTs available of which all are handled.
101 If unsure, say Y. To compile this driver as a module, choose M here:
102 the module will be called sb1250-duart.
104 config SERIAL_SB1250_DUART_CONSOLE
105 bool "Support for console on a BCM1xxx DUART serial port"
106 depends on SERIAL_SB1250_DUART=y
107 select SERIAL_CORE_CONSOLE
110 If you say Y here, it will be possible to use a serial port as the
111 system console (the system console is the device which receives all
112 kernel messages and warnings and which allows logins in single user
118 bool "AT91 on-chip serial port support"

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

199 Say Y here if you wish to use a KS8695 (Centaur) UART as the
200 system console (the system console is the device which
201 receives all kernel messages and warnings and which allows
202 logins in single user mode).

206 depends on ARCH_MESON
209 This enables the driver for the on-chip UARTs of the Amlogic

321 providing /dev/ttyTHS0, 1, 2, 3 and 4 (note, some machines may not
322 provide all of these ports, depending on how the serial port
323 are enabled). This driver uses the APB DMA to achieve higher baudrate
324 and better performance.

788 both z85C30 and 8250 type ports at the same time.
790 If this option is not selected, the pmac_zilog driver will

792 the pmac_zilog and 8250 drivers to co-exist, but may cause
793 existing userspace setups to break. Programs that need to
794 access the built-in serial ports on powermacs will need to
795 be reconfigured to use /dev/ttyPZn instead of /dev/ttySn.
797 If you enable this option, any z85c30 ports in the system will

1434 ASC is embedded in ST COMMS IP block. It supports Rx & Tx functionality.
1435 It support all industry standard baud rates.
1439 config SERIAL_ST_ASC_CONSOLE
1440 bool "Support for console on ST ASC"
1441 depends on SERIAL_ST_ASC=y
1442 select SERIAL_CORE_CONSOLE
1444 config SERIAL_MEN_Z135
1445 tristate "MEN 16z135 Support"
1449 Say yes here to enable support for the MEN 16z135 High Speed UART IP-Core
1452 This driver can also be build as a module. If so, the module will be called
1456 tristate "Support for Spreadtrum serial"
1457 depends on ARCH_SPRD
1460 This enables the driver for the Spreadtrum's serial.
1462 config SERIAL_SPRD_CONSOLE
1463 bool "Spreadtrum UART console support"
1464 depends on SERIAL_SPRD=y
1465 select SERIAL_CORE_CONSOLE
1466 select SERIAL_EARLYCON
1468 Support for early debug console using Spreadtrum's serial. This enables
1469 the console before standard serial driver is probed. This is enabled
1470 with "earlycon" on the kernel command line. The console is
1471 enabled when early_param is processed.
1474 tristate "STMicroelectronics STM32 serial port support"
1476 depends on ARCH_STM32 || COMPILE_TEST
1478 This driver is for the on-chip Serial Controller on
1479 STMicroelectronics STM32 MCUs.
1480 USART supports Rx & Tx functionality.
1481 It support all industry standard baud rates.
1485 config SERIAL_STM32_CONSOLE
1486 bool "Support for console on STM32"
1487 depends on SERIAL_STM32=y
1488 select SERIAL_CORE_CONSOLE
1490 config SERIAL_MVEBU_UART
1491 bool "Marvell EBU serial port support"
1492 depends on ARCH_MVEBU || COMPILE_TEST
1495 This driver is for Marvell EBU SoC's UART. If you have a machine
1496 based on the Armada-3700 SoC and wish to use the on-board serial
1501 config SERIAL_MVEBU_CONSOLE
1502 bool "Console on Marvell EBU serial port"
1503 depends on SERIAL_MVEBU_UART
1504 select SERIAL_CORE_CONSOLE
1505 select SERIAL_EARLYCON
1508 Say 'Y' here if you wish to use Armada-3700 UART as the system console.
1509 (the system console is the device which receives all kernel messages
1510 and warnings and which allows logins in single user mode)
1514 tristate "Actions Semi Owl serial port support"
1515 depends on ARCH_ACTIONS || COMPILE_TEST
1518 This driver is for Actions Semiconductor S500/S900 SoC's UART.
1519 Say 'Y' here if you wish to use the on-board serial port.
1522 config SERIAL_OWL_CONSOLE
1523 bool "Console on Actions Semi Owl serial port"
1524 depends on SERIAL_OWL=y
1525 select SERIAL_CORE_CONSOLE
1526 select SERIAL_EARLYCON
1529 Say 'Y' here if you wish to use Actions Semiconductor S500/S900 UART
1530 as the system console.
