-Subject: [PATCH 065/203] bus: mvebu-mbus: Add devicetree binding
-
-Introduce the devicetree binding for the mvebu MBus driver
-avaiable in the mvebu SoCs (Armada 370/XP, Kirkwood, Dove, ...).
-
-This binding provides an accurate model of the SoC address space,
-and allows to declare the address and size of the decoding windows the MBus
-needs to access the peripherals, together with the target ID and attribute
-for those windows.
-
-The binding is composed of two required nodes: one for the MBus bus
-and one for the MBus controller.

-+
-+- address-cells: Must be '2'. The first cell for the MBus ID encoding,

-+
-+- ranges: Must be set up to provide a proper translation for each child.

-+ within the internal register window (see below).
-+
-+Optional properties:
-+
-+- pcie-mem-aperture: This optional property contains the aperture for
-+ the memory region of the PCIe driver.
-+ If it's defined, it must encode the base address and
-+ size for the address decoding windows allocated for
-+ the PCIe memory region.
-+
-+- pcie-io-aperture: Just as explained for the above property, this
-+ optional property contains the aperture for the
-+ I/O region of the PCIe driver.
-+
-+* Marvell MBus controller
-+
-+Required properties:
-+
-+- compatible: Should be set to "marvell,mbus-controller".
-+
-+- reg: Device's register space.
-+ Two entries are expected (see the examples below):
-+ the first one controls the devices decoding window and
-+ the second one controls the SDRAM decoding window.
-+
-+Example:
-+
-+ soc {
-+ compatible = "marvell,armada370-mbus", "simple-bus";
-+ #address-cells = <2>;
-+ #size-cells = <1>;
-+ controller = <&mbusc>;
-+ pcie-mem-aperture = <0xe0000000 0x8000000>;
-+ pcie-io-aperture = <0xe8000000 0x100000>;
-+
-+ internal-regs {
-+ compatible = "simple-bus";
-+
-+ mbusc: mbus-controller@20000 {
-+ compatible = "marvell,mbus-controller";
-+ reg = <0x20000 0x100>, <0x20180 0x20>;
-+ };
-+
-+ /* more children ...*/
-+ };
-+ };
-+
-+** MBus address decoding window specification
-+
-+The MBus children address space is comprised of two cells: the first one for
-+the window ID and the second one for the offset within the window.
-+In order to allow to describe valid and non-valid window entries, the
-+following encoding is used:
-+
-+ 0xSIAA0000 0x00oooooo
-+
-+Where:
-+
-+ S = 0x0 for a MBus valid window
-+ S = 0xf for a non-valid window (see below)
-+
-+If S = 0x0, then:
-+
-+ I = 4-bit window target ID
-+ AA = windpw attribute
-+
-+If S = 0xf, then:
-+
-+ I = don't care
-+ AA = 1 for internal register
-+
-+Following the above encoding, for each ranges entry for a MBus valid window
-+(S = 0x0), an address decoding window is allocated. On the other side,
-+entries for translation that do not correspond to valid windows (S = 0xf)
-+are skipped.
-+
-+ soc {
-+ compatible = "marvell,armada370-mbus", "simple-bus";
-+ #address-cells = <2>;
-+ #size-cells = <1>;
-+ controller = <&mbusc>;
-+
-+ ranges = <0xf0010000 0 0 0xd0000000 0x100000
-+ 0x01e00000 0 0 0xfff00000 0x100000>;
-+
-+ bootrom {
-+ compatible = "marvell,bootrom";
-+ reg = <0x01e00000 0 0x100000>;
-+ };
-+
-+ /* other children */
-+ ...
-+
-+ internal-regs {
-+ compatible = "simple-bus";
-+ ranges = <0 0xf0010000 0 0x100000>;
-+
-+ mbusc: mbus-controller@20000 {
-+ compatible = "marvell,mbus-controller";
-+ reg = <0x20000 0x100>, <0x20180 0x20>;
-+ };
-+
-+ /* more children ...*/
-+ };
-+ };
-+
-+In the shown example, the translation entry in the 'ranges' property is what
-+makes the MBus driver create a static decoding window for the corresponding
-+given child device. Note that the binding does not require child nodes to be
-+present. Of course, child nodes are needed to probe the devices.
-+
-+Since each window is identified by its target ID and attribute ID there's
-+a special macro that can be use to simplify the translation entries:
-+
-+#define MBUS_ID(target,attributes) (((target) << 24) | ((attributes) << 16))
-+
-+Using this macro, the above example would be:
-+
-+ soc {
-+ compatible = "marvell,armada370-mbus", "simple-bus";
-+ #address-cells = <2>;
-+ #size-cells = <1>;
-+ controller = <&mbusc>;
-+
-+ ranges = < MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000
-+ MBUS_ID(0x01, 0xe0) 0 0 0xfff00000 0x100000>;
-+
-+ bootrom {
-+ compatible = "marvell,bootrom";
-+ reg = <MBUS_ID(0x01, 0xe0) 0 0x100000>;
-+ };
-+
-+ /* other children */
-+ ...
-+
-+ internal-regs {
-+ compatible = "simple-bus";
-+ #address-cells = <1>;
-+ #size-cells = <1>;
-+ ranges = <0 MBUS_ID(0xf0, 0x01) 0 0x100000>;
-+
-+ mbusc: mbus-controller@20000 {
-+ compatible = "marvell,mbus-controller";
-+ reg = <0x20000 0x100>, <0x20180 0x20>;
-+ };
-+
-+ /* other children */
-+ ...
-+ };
-+ };
-+
-+
-+** About the window base address
-+
-+Remember the MBus controller allows a great deal of flexibility for choosing
-+the decoding window base address. When planning the device tree layout it's
-+possible to choose any address as the base address, provided of course there's
-+a region large enough available, and with the required alignment.
-+
-+Yet in other words: there's nothing preventing us from setting a base address
-+of 0xf0000000, or 0xd0000000 for the NOR device shown above, if such region is
-+unused.
-+
-+** Window allocation policy
-+
-+The mbus-node ranges property defines a set of mbus windows that are expected
-+to be set by the operating system and that are guaranteed to be free of overlaps
-+with one another or with the system memory ranges.
-+
-+Each entry in the property refers to exactly one window. If the operating system
-+choses to use a different set of mbus windows, it must ensure that any address
-+translations performed from downstream devices are adapted accordingly.
-+
-+The operating system may insert additional mbus windows that do not conflict
-+with the ones listed in the ranges, e.g. for mapping PCIe devices.
-+As a special case, the internal register window must be set up by the boot
-+loader at the address listed in the ranges property, since access to that region
-+is needed to set up the other windows.
-+
-+** Example
-+
-+See the example below, where a more complete device tree is shown:
-+
-+ soc {
-+ compatible = "marvell,armadaxp-mbus", "simple-bus";
-+ controller = <&mbusc>;

-+ MBUS_ID(0x01, 0x2f) 0 0 0xf0000000 0x8000000>;
