tegra: Convert tegra GPIO driver to use driver model 2014-09-10T18:59:59+00:00 Simon Glass sjg@chromium.org 2014-09-03T23:37:03+00:00 2fccd2d96badcdf6165658a99771a4c475586279 This is an implementation of GPIOs for Tegra that uses driver model. It has been tested on trimslice and also using the new iotrace feature. The implementation uses a top-level GPIO device (which has no actual GPIOS). Under this all the banks are created as separate GPIO devices. The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7, ..., Z0..Z7, AA0..AA7, etc. Since driver model is not yet available before relocation, or in SPL, a special function is provided for seaboard's SPL code.

Driver model does not support SPL yet, so we should not use the GPIO
uclass for SPL.

gpio: spear_gpio: Fix gpio_set_value() implementation

In current gpio_set_value() implementation, it always sets the gpio control bit
no matter the value argument is 0 or 1. Thus the GPIOs never set to low.
This patch fixes this bug.

The address bus is used as a mask on read/write operations, so that independent
software drivers can set their GPIO bits without affecting any other pins in a
single write operation. Thus we don't need a read-modify-write to update the
register.

We want 'N0' and 'n0' to mean the same thing, so ensure that case is not
considered when naming GPIO banks.

It is best to avoid having any occurence of 'struct device' in driver
model, so rename to achieve this.

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"
