416 This option enables the host functionality of the ETRAX 100LX
417 built-in USB controller. In host mode the controller is designed
418 for CTRL and BULK traffic only, INTR traffic may work as well
419 however (depending on the requirements of timeliness).
421 config ETRAX_USB_HOST_PORT1
422 bool "USB port 1 enabled"
423 depends on ETRAX_USB_HOST
426 config ETRAX_USB_HOST_PORT2
427 bool "USB port 2 enabled"
428 depends on ETRAX_USB_HOST
431 config ETRAX_PTABLE_SECTOR
432 int "Byte-offset of partition table sector"
433 depends on ETRAX_AXISFLASHMAP
436 Byte-offset of the partition table in the first flash chip.
437 The default value is 64kB and should not be changed unless
438 you know exactly what you are doing. The only valid reason
439 for changing this is when the flash block size is bigger
440 than 64kB (e.g. when using two parallel 16 bit flashes).
444 depends on ETRAX_ARCH_V10
446 Enables an I2C driver on ETRAX100.

450 i2c_arg = I2C_READARG(STA013_READ_ADDR, reg);
451 val = ioctl(fd, _IO(ETRAXI2C_IOCTYPE, I2C_READREG), i2c_arg);
453 # this is true for most products since PB-I2C seems to be somewhat
455 config ETRAX_I2C_USES_PB_NOT_PB_I2C
456 bool "I2C uses PB not PB-I2C"
459 Select whether to use the special I2C mode in the PB I/O register or
460 not. This option needs to be selected in order to use some drivers
461 that access the I2C I/O pins directly instead of going through the
462 I2C driver, like the DS1302 realtime-clock driver. If you are
463 uncertain, choose Y here.
465 config ETRAX_I2C_DATA_PORT
466 int "I2C SDA bit number"

477 Select the pin on Port B where the clock pin is connected
479 config ETRAX_I2C_EEPROM
480 bool "I2C EEPROM (non-volatile RAM) support"
483 Enables I2C EEPROM (non-volatile RAM) on PB0 and PB1 using the I2C
484 driver. Select size option: Probed, 2k, 8k, 16k.
485 (Probing works for 2k and 8k but not that well for 16k)
489 depends on ETRAX_I2C_EEPROM
490 default ETRAX_I2C_EEPROM_PROBE
492 config ETRAX_I2C_EEPROM_PROBE
495 Specifies size or auto probe of the EEPROM size.
496 Options: Probed, 2k, 8k, 16k.

499 config ETRAX_I2C_EEPROM_2KB
504 config ETRAX_I2C_EEPROM_8KB
509 config ETRAX_I2C_EEPROM_16KB
518 depends on ETRAX_ARCH_V10
520 Enables the ETRAX general port device (major 120, minors 0 and 1).
521 You can use this driver to access the general port bits. It supports
523 #include <linux/etraxgpio.h>
524 fd = open("/dev/gpioa", O_RDWR); // or /dev/gpiob
525 ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_SETBITS), bits_to_set);
526 ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_CLRBITS), bits_to_clear);
527 val = ioctl(fd, _IO(ETRAXGPIO_IOCTYPE, IO_READBITS), NULL);
528 Remember that you need to setup the port directions appropriately in
529 the General configuration.
531 config ETRAX_PA_BUTTON_BITMASK
532 hex "PA-buttons bitmask"
533 depends on ETRAX_GPIO
536 This is a bitmask with information about what bits on PA that
537 are used for buttons.
538 Most products has a so called TEST button on PA1, if that's true
540 Use 00 if there are no buttons on PA.
541 If the bitmask is <> 00 a button driver will be included in the gpio
542 driver. ETRAX general I/O support must be enabled.
544 config ETRAX_PA_CHANGEABLE_DIR
545 hex "PA user changeable dir mask"
546 depends on ETRAX_GPIO
549 This is a bitmask with information of what bits in PA that a user
550 can change direction on using ioctl's.
551 Bit set = changeable.
552 You probably want 00 here.
554 config ETRAX_PA_CHANGEABLE_BITS
555 hex "PA user changeable bits mask"
556 depends on ETRAX_GPIO
559 This is a bitmask with information of what bits in PA that a user

575 hex "PB user changeable bits mask"
576 depends on ETRAX_GPIO
579 This is a bitmask with information of what bits in PB that a user
580 can change the value on using ioctl's.
581 Bit set = changeable.
582 You probably want 00 here.
584 config ETRAX_DS1302_RST_ON_GENERIC_PORT
585 bool "DS1302 RST on Generic Port"
586 depends on ETRAX_DS1302
588 If your product has the RST signal line for the DS1302 RTC on the
589 Generic Port then say Y here, otherwise leave it as N in which
590 case the RST signal line is assumed to be connected to Port PB
591 (just like the SCL and SDA lines).
593 config ETRAX_DS1302_RSTBIT
594 int "DS1302 RST bit number"
595 depends on ETRAX_DS1302
598 This is the bit number for the RST signal line of the DS1302 RTC on
599 the selected port. If you have selected the generic port then it
600 should be bit 27, otherwise your best bet is bit 5.
602 config ETRAX_DS1302_SCLBIT
603 int "DS1302 SCL bit number"
604 depends on ETRAX_DS1302
607 This is the bit number for the SCL signal line of the DS1302 RTC on
608 Port PB. This is probably best left at 3.
610 config ETRAX_DS1302_SDABIT
611 int "DS1302 SDA bit number"
612 depends on ETRAX_DS1302
615 This is the bit number for the SDA signal line of the DS1302 RTC on
616 Port PB. This is probably best left at 2.
618 config ETRAX_DS1302_TRICKLE_CHARGE
619 int "DS1302 Trickle charger value"
620 depends on ETRAX_DS1302
623 This controls the initial value of the trickle charge register.
624 0 = disabled (use this if you are unsure or have a non rechargeable battery)
625 Otherwise the following values can be OR:ed together to control the
627 1 = 2kohm, 2 = 4kohm, 3 = 4kohm
628 4 = 1 diode, 8 = 2 diodes
629 Allowed values are (increasing current): 0, 11, 10, 9, 7, 6, 5
