2017-06-01dm: Fix up inclusion of common.hSimon Glass
It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2015-09-11gpio: lpc32xx: fix issues with port3 gpioSylvain Lemieux
The current simplify lpc32xx gpio driver implementation assume a maximum of 32 GPIO per port; there are a total of 22 GPI, 24 GPO and 6 GPIO to managed on port 3. Update the driver to fix the following: 1) When requesting GPI_xx and GPO_xx on port 3 (xx is the same number) the second call to "gpio_request" will return -EBUSY. 2) The status of GPO_xx pin report the status of the corresponding GPI_xx pin when using the "gpio status" command. 3) The gpio driver may setup the direction register for the wrong gpio when calling "gpio_direction_input" (GPI_xx) or "gpio_direction_output" (GPO_xx) on port 3; the call to the direction is require to use the "gpio status" command. The following change were done in the driver: 1) port3 GPI are cache in a separate 32 bits in the array. 2) port3 direction register written only for GPIO pins. 3) port3 GPO & GPIO (as output) are read using "p3_outp_state". 4) LPC32XX_GPI_P3_GRP updated to match the change.

2015-07-07gpio: lpc32xx: Use priv_data instead of platdataAxel Lin
The LPC32XX GPIO driver platdata currently contains GPIO state information, which should go into priv_data. Thus rename lpc32xx_gpio_platdata to lpc32xx_gpio_priv and convert to use dev_get_priv() instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Tested-by: Albert ARIBAUD <albert.aribaud@3adev.fr>
