Add the bare minimum needed to boot BCM2708 from a Device Tree. Signed-off-by: Noralf Tronnes <notro@tronnes.org> BCM2708: DT: change 'axi' nodename to 'soc' Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835. The VC4 bootloader fills in certain properties in the 'axi' subtree, but since this is part of an upstreaming effort, the name is changed. Signed-off-by: Noralf Tronnes notro@tronnes.org BCM2708_DT: Correct length of the peripheral space Use dts-dirs feature for overlays. The kernel makefiles have a dts-dirs target that is for vendor subdirectories. Using this fixes the install_dtbs target, which previously did not install the overlays. BCM270X_DT: configure I2S DMA channels Signed-off-by: Matthias Reichl <hias@horus.com> BCM270X_DT: switch to bcm2835-i2s I2S soundcard drivers with proper devicetree support (i.e. not linking to the cpu_dai/platform via name but to cpu/platform via of_node) will work out of the box without any modifications. When the kernel is compiled without devicetree support the platform code will instantiate the bcm2708-i2s driver and I2S soundcard drivers will link to it via name, as before.
