dm: Move the function for getting GPIO status into the uclass

2014-10-24T01:29:52+00:00

This function can be more easily tested if it is in the uclass.

dm: gpio: Allow gpio command to adjust GPIOs that are busy

2014-09-01T05:21:19+00:00

The gpio command mostly relies on gpio_request() and gpio_free() being
nops, in that you can request a GPIO twice. With driver model this is
now implemented correctly, so it fails.

Change the command to deal with a failure to claim the GPIO.

dm: gpio: Enhance gpio command to show only active GPIOs

2014-09-01T05:21:06+00:00

The GPIO list is very long in many cases and most of them are not used.
By default, show only the GPIOs that are in use, and provide a flag to show
all of them. This makes the 'gpio status' command much more pleasant.

In order to do this, driver model now exposes a method for obtaining the
'function' of a GPIO, which describes whether it is an input or output, for
example. Implementation of this method is optional.

dm: rename device struct to udevice

2014-05-27T14:21:32+00:00

using UBI and DM together leads in compiler error, as
both define a "struct device", so rename "struct device"
in include/dm/device.h to "struct udevice", as we use
linux code (MTD/UBI/UBIFS some USB code,...) and cannot
change the linux "struct device"

blackfin: make name_to_gpio be a weak symbol

2014-04-18T14:42:29+00:00

This required moving it into a C file from the header.

The only user of a non-default name_to_gpio is blackfin, therefore build tested
with the blackfin bct-brettl2 build, which is one I picked at random. Also
tested with a build for the ARM tec board which uses the default/fallback
implementation. Inspection with objdump shows that both have done the right
thing.

This change was requested by Marek during review of the sunxi patch series.

dm: Enable gpio command to support driver model

2014-03-04T17:15:30+00:00

Now that named GPIO banks are supported, along with a way of obtaining
the status of a GPIO (input or output), we can provide an enhanced
GPIO command for driver model. Where the driver provides its own operation
for obtaining the GPIO state, this is used, otherwise a generic version
is sufficient.

Convert cmd_usage() calls in common to use a return value

2012-03-06T20:09:46+00:00

Change all files in common/ to use CMD_RET_USAGE instead of calling
cmd_usage() directly. I'm not completely sure about this patch since
the code since impact is small (100 byte or so on ARM) and it might
need splitting into smaller patches. But for now here it is.

gpio: check request result

Make sure the pin request passed before attempting to use it later on.
