Filenames of devictree binding documentation seems to be arbitrary and for me it is unneeded hazzle to find the corresponding documentation for a specific driver. Naming the description the same as the driver is a lot easier and makes sense to me since the driver defines the binding it understands. Also, remove a reference in one source to the binding documentation, since path information easily gets stale. Signed-off-by:

* Marvell MMP I2C controller
Required properties :
- reg : Offset and length of the register set for the device
- compatible : should be "mrvl,mmp-twsi" where mmp is the name of a
compatible processor, e.g. pxa168, pxa910, mmp2, mmp3.
For the pxa2xx/pxa3xx, an additional node "mrvl,pxa-i2c" is required
as shown in the example below.
Recommended properties :
- interrupts : the interrupt number
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device. If the parent is the default
interrupt controller in device tree, it could be ignored.
- mrvl,i2c-polling : Disable interrupt of i2c controller. Polling
status register of i2c controller instead.
- mrvl,i2c-fast-mode : Enable fast mode of i2c controller.
Examples:
twsi1: i2c@d4011000 {
compatible = "mrvl,mmp-twsi";
reg = <0xd4011000 0x1000>;
interrupts = <7>;
mrvl,i2c-fast-mode;
};
twsi2: i2c@d4025000 {
compatible = "mrvl,mmp-twsi";
reg = <0xd4025000 0x1000>;
interrupts = <58>;
};
