MIPS: RB532: Fix devices.c compilation.

2009-12-02T18:09:51+00:00

We should now use dev_set_drvdata to set the driver driver_data field.

Input: add driver for S1 button of rb532

2009-03-10T03:10:12+00:00

Mikrotik's Routerboard 532 has two builtin buttons, from which one
triggers a hardware reset. The other one is accessible through GPIO
pin 1. Sadly, this pin is being multiplexed with UART0 input, so
enabling it as interrupt source (as implied by the gpio-keys driver)
is not possible unless UART0 has been turned off. The later one though
is a rather bad idea as the Routerboard is an embedded device with
only a single serial port, so it's almost always used as serial
console device.

This patch adds a driver based on INPUT_POLLDEV, which disables the
UART and reconfigures GPIO pin 1 temporarily while reading the button
state.  This procedure works fine and has been tested as part of
another, unpublished driver for this device.

MIPS: RB532: Simplify dev3 init

2009-01-30T21:33:01+00:00

As rb532_dev3_ctl_res is not used by any platform device, it can be dropped
when not used for holding the physical address of the device 3 controller.

Also a size of one byte should suffice when ioremapping the physical
address mentioned above, as only a single byte is being read from and
written to it.

MIPS: RB532: Move dev3 init code to devices.c

2009-01-30T21:33:00+00:00

This code doesn't belong to gpio.c, as it's completely unrelated to
GPIO. As dev1 and dev2 init code is in devices.c, it seems to be a more
adequate place.

MIPS: RB532: Use driver_data instead of platform_data

2009-01-30T21:33:00+00:00

As the korina ethernet driver uses platform_get_drvdata() to extract the
driver specific data from the platform device, driver_data has to be
used here.

MIPS: RB532: Detect uart type, add platform device

2009-01-30T21:33:00+00:00

Auto-detection works just fine, so use it instead of specifying the type
manually. Also define a platform device for the uart, as suggested by
David Daney.

MIPS: RB532: GPIO register offsets are relative to GPIOBASE

2008-11-20T19:42:32+00:00

This patch fixes the wrong use of GPIO register offsets
in devices.c. To avoid further problems, use gpio_get_value
to return the NAND status instead of our own expanded code.

Also define the zero offset of the alternate function register to allow
consistent access.

MIPS: RB532: Fix id usage in platform devices

2008-10-11T15:18:46+00:00

When there is only platform device of the same type, id = -1
should be used, fix this.
