* tegra: video: Convert tegra20 LCD driver to driver modelSimon Glass2016-02-161-213/+172
| | | | | | | | | | | Move this driver over to use driver model. This involves rearranging the code somewhat. The effect is that everything is run from the probe() method. Boards which use this are fixed up, but only seaboard is tested.

| | | | | | | | | | | At present we have code in arch/arm and code in drivers/video. Move it all into drivers/video since it is a display driver and our current approach is to put all driver code in drivers/. Make a few functions static now that they are not used outside the file.

* tegra: gpio: Show the GPIO value for outputsSimon Glass2016-02-161-1/+4
| | | | | | | | | | | | | | | | | | | The tegra GPIO controller has two ways of reading the value of a GPIO. It can supply the 'input' value (which is the value read from the pin) and the 'output' value (which is the value being driven from the pin. With a GPIO set to output mode, the 'input' value is always low which is not very useful. This has the unfortunate result that setting a GPIO high still leaves it showing as low in the 'gpio status' command. Adjust the driver to check which direction the GPIO is set to, then read the value from the appropriate register: 'input' for input GPIOs, 'output' for output GPIOs.

| * video: bcm2835: use bus_to_phys() on FB addressStephen Warren2016-02-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FB address is generated by the firmware running on the GPU/VideoCore and is a "bus" address. This address is the other side of an IOMMU from the ARM upon which U-Boot is running. Use bus_to_phys() to convert this to an ARM physical address. Without this, U-Boot seems to work just fine, but once the Linux kernel boots on an RPi2, accessing the FB memory often causes a hard system hang.
