From 6b5917890ada1dc078ee64af2500cd6289fcf9bc Mon Sep 17 00:00:00 2001
From: Andrew Murray <Andrew.Murray@arm.com>

Subject: [PATCH 01/29] of/pci: Provide support for parsing PCI DT ranges
property
This patch factors out common implementation patterns to reduce overall kernel
code and provide a means for host bridge drivers to directly obtain struct
resources from the DT's ranges property without relying on architecture specific
DT handling. This will make it easier to write archiecture independent host bridge
drivers and mitigate against further duplication of DT parsing code.
This patch can be used in the following way:
struct of_pci_range_parser parser;
struct of_pci_range range;
if (of_pci_range_parser_init(&parser, np))
; //no ranges property
for_each_of_pci_range(&parser, &range) {
/*
directly access properties of the address range, e.g.:
range.pci_space, range.pci_addr, range.cpu_addr,
range.size, range.flags
alternatively obtain a struct resource, e.g.:
struct resource res;
of_pci_range_to_resource(&range, np, &res);
*/
}
Additionally the implementation takes care of adjacent ranges and merges them
into a single range (as was the case with powerpc and microblaze).

Subject: [PATCH 04/29] clk: mvebu: create parent-child relation for PCIe
clocks on Armada 370
The Armada 370 has two gatable clocks for each PCIe interface, and we
want both of them to be enabled. We therefore make one of the two
clocks a child of the other, as we did for the sataX and sataXlnk
clocks on Armada XP.

Subject: [PATCH 05/29] clk: mvebu: add more PCIe clocks for Armada XP
The current revision of the datasheet only mentions the gatable clocks
for the PCIe 0.0, 0.1, 0.2 and 0.3 interfaces, and forgot to mention
the ones for the PCIe 1.0, 1.1, 1.2, 1.3, 2.0 and 3.0
interfaces. After confirmation with Marvell engineers, this patch adds
the missing gatable clocks for those PCIe interfaces.
It also changes the name of the previously existing PCIe gatable
clocks, in order to match the naming using the datasheets.

Subject: [PATCH 07/29] arm: mvebu: PCIe support is now available on mvebu
Now that the PCIe driver for mvebu has been integrated and all its
relevant dependencies, we can mark the ARCH_MVEBU platform has
MIGHT_HAVE_PCI, which allows to select the PCI bus support if needed.

Now that we have the necessary drivers and Device Tree informations to
support PCIe on Armada 370 and Armada XP, enable the CONFIG_PCI
option.
Also, since the Armada 370 Mirabox has a built-in USB XHCI controller
connected on the PCIe bus, enable the corresponding options as well.

Subject: [PATCH 10/29] arm: kirkwood: move PCIe window init to legacy driver
Since we are going to enable the usage of the mvebu PCIe driver on
Kirkwood, we don't want the PCIe windows to be unconditionally created
by kirkwood_setup_wins(). Therefore, we move the PCIe window
initialization into the legacy PCIe driver
(arch/arm/mach-kirkwood/pcie.c).
The platforms using the legacy driver will see their windows
statically allocated by
arch/arm/mach-kirkwood/pcie.c:kirkwood_pcie_init(). The platforms
using the new driver in drivers/pci/ will see their windows
dynamically allocated directly by the driver.

Subject: [PATCH 15/29] arm: kirkwood: convert QNAP TS219 to use DT for the
PCIe interface
Now that the PCIe mvebu driver is usable on Kirkwood, use it instead
of the legacy PCIe code, since it allows to describe the PCIe
interfaces in the Device Tree.

Subject: [PATCH 16/29] arm: kirkwood: convert db-88f6281/db-88f6282 to the
Device Tree
This commit converts the Marvell DB-88F6281/DB-88F6282 board to the
Device Tree. In fact, the code was supporting two different boards:
one with the 6281 SoC variant, and one with the 6282 SoC variant. The
difference between the two being that the 6281 has one PCIe interface,
and the 6282 has two PCIe interfaces.
In order to handle that with the Device Tree, we create a
'kirkwood-db.dtsi' file that contains the definitions common to both
boards, and 'kirkwood-db-88f6281.dts' and 'kirkwood-db-88f6282.dts'
for the definitions specific to each board. This is similar to what is
done for the QNAP TS219 Kirkwood platform.
We have kept one single Kconfig option, just like it was before.

Subject: [PATCH 18/29] net: mv643xx_eth: use phy_disconnect instead of
phy_detach
Using a separated mdio bus driver with mvmdio, phy_detach on network device
removal will not stop the phy and finally lead to NULL pointer dereference
in mvmdio due to non-existent network device. Use phy_disconnect instead
to properly stop phy device from accessing network device prior removal of
the network device.

Subject: [PATCH 22/29] net: mv643xx_eth: proper initialization for Kirkwood
SoCs
Ethernet controllers found on Kirkwood SoCs not only suffer from loosing
MAC address register contents on clock gating but also some important
registers are reset to values that would break ethernet. This patch
clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using
of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not
affected as it installs a clock gating workaround because of the MAC
address issue above. Other Orion SoCs do not suffer from register reset,
do not have the bit in question, or do not have the register at all.
Moreover, system controllers on PPC using this driver should also be
protected from clearing that bit.

This adds device tree parsing support for the shared driver of mv643xx_eth.
As the bindings are slightly different from current PPC bindings new binding
documentation is also added. Following PPC-style device setup, the shared
driver now also adds port platform_devices and sets up port platform_data.

+Marvell Orion/Discovery ethernet controller
+=============================================
+
+The Marvell Discovery ethernet controller can be found on Marvell Orion SoCs
+(Kirkwood, Dove, Orion5x, and Discovery Innovation) and as part of Marvell
+Discovery system controller chips (mv64[345]60).
+
+The Discovery ethernet controller is described with two levels of nodes. The
+first level describes the ethernet controller itself and the second level
+describes up to 3 ethernet port nodes within that controller. The reason for
+the multiple levels is that the port registers are interleaved within a single
+set of controller registers. Each port node describes port-specific properties.
+
+Note: The above separation is only true for Discovery system controllers.
+For Orion SoCs we stick to the separation, although there each controller has
+only one port associated. Multiple ports are implemented as multiple single-port
+controllers. As Kirkwood has some issues with proper initialization after reset,
+an extra compatible string is added for it.
+
+* Ethernet controller node
+
+Required controller properties:
+ - #address-cells: shall be 1.
+ - #size-cells: shall be 0.
+ - compatible: shall be one of "marvell,orion-eth", "marvell,kirkwood-eth".
+ - reg: address and length of the controller registers.
+
+Optional controller properties:
+ - clocks: phandle reference to the controller clock.
+ - marvell,tx-checksum-limit: max tx packet size for hardware checksum.
+
+* Ethernet port node
+
+Required port properties:
+ - device_type: shall be "network".
+ - compatible: shall be one of "marvell,orion-eth-port",
+ "marvell,kirkwood-eth-port".
+ - reg: port number relative to ethernet controller, shall be 0, 1, or 2.
+ - interrupts: port interrupt.
+ - local-mac-address: 6 bytes MAC address.
+
+Optional port properties:
+ - marvell,tx-queue-size: size of the transmit ring buffer.
+ - marvell,tx-sram-addr: address of transmit descriptor buffer located in SRAM.
+ - marvell,tx-sram-size: size of transmit descriptor buffer located in SRAM.
+ - marvell,rx-queue-size: size of the receive ring buffer.
+ - marvell,rx-sram-addr: address of receive descriptor buffer located in SRAM.
+ - marvell,rx-sram-size: size of receive descriptor buffer located in SRAM.
+
+and
+
+ - phy-handle: phandle reference to ethernet PHY.
+
+or
+
+ - speed: port speed if no PHY connected.
+ - duplex: port mode if no PHY connected.
+
+* Node example:
+
+mdio-bus {
+ ...
+ ethphy: ethernet-phy@8 {
+ device_type = "ethernet-phy";
+ ...
+ };
+};
+
+eth: ethernet-controller@72000 {
+ compatible = "marvell,orion-eth";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <0x72000 0x2000>;
+ clocks = <&gate_clk 2>;
+ marvell,tx-checksum-limit = <1600>;
+
+ ethernet@0 {
+ device_type = "network";
+ compatible = "marvell,orion-eth-port";
+ reg = <0>;
+ interrupts = <29>;
+ phy-handle = <&ethphy>;
+ local-mac-address = [00 00 00 00 00 00];
+ };
+};

Subject: [PATCH 25/29] ARM: kirkwood: remove redundant DT board files
With DT support for mv643xx_eth board specific init for some boards now
is unneccessary. Remove those board files, Kconfig entries, and
corresponding entries in kirkwood_defconfig.

Subject: [PATCH 27/29] net: mv643xx_eth: do not use port number as platform
device id
The port number is only local to the ethernet block, not global, so
there can be two ethernet blocks both using the same port, like
kirkwood with both using port 0.
Fix this by using the array index offset for the allocated platform
devices as the id.
