-Subject: [PATCH 04/31] pinctrl: Add skew-delay pin config and bindings
-
-Some pin controllers (such as the Gemini) can control the
-expected clock skew and output delay on certain pins with a
-sub-nanosecond granularity. This is typically done by shunting
-in a number of double inverters in front of or behind the pin.
-Make it possible to configure this with a generic binding.

-Subject: [PATCH 16/31] ARM: dts: Add TVE/TVC and ILI9322 panel to DIR-685
-
-This adds the TVE200/TVC TV-encoder and the Ilitek ILI9322 panel
-to the DIR-685 device tree.
-
-This brings graphics to this funky router and it is possible to
-even run a console on its tiny screen.
-
-Incidentally this requires us to disable the access to the
-parallel (NOR) flash, as the communication pins to the panel
-are shared with the flash memory.
-
-To access the flash, a separate kernel with the panel disabled
-and the flash enabled should be booted. The pin control selecting
-whether to use the lines cannot be altered at runtime due to
-hardware constraints.

-Subject: [PATCH 19/31] watchdog: ftwdt010: Make interrupt optional
-
-The Moxart does not appear to be using the interrupt from the
-watchdog timer, maybe it's not even routed, so as to support
-more architectures with this driver, make the interrupt
-optional.
-
-While we are at it: actually enable the use of the interrupt
-if present by setting the right bit in the control register
-and define the missing control register bits.

-Subject: [PATCH 20/31] soc: Add SoC driver for Gemini
-
-This adds an SoC driver for the Gemini. Currently there
-is only one thing not fitting into any other framework,
-and that is the bus arbitration setting.
-
-All Gemini vendor trees seem to be setting this register to
-exactly the same arbitration so we just add a small code
-snippet to do this at subsys_init() time before any other
-drivers kick in.

-This adds the device tree bindings for the Gemini ethernet

-+Cortina Systems Gemini Ethernet Controller
-+==========================================
-+
-+This ethernet controller is found in the Gemini SoC family:
-+StorLink SL3512 and SL3516, also known as Cortina Systems
-+CS3512 and CS3516.
-+
-+Required properties:
-+- compatible: must be "cortina,gemini-ethernet"
-+- reg: must contain the global registers and the V-bit and A-bit
-+ memory areas, in total three register sets.
-+- syscon: a phandle to the system controller
-+- #address-cells: must be specified, must be <1>
-+- #size-cells: must be specified, must be <1>
-+- ranges: should be state like this giving a 1:1 address translation
-+ for the subnodes
-+
-+The subnodes represents the two ethernet ports in this device.
-+They are not independent of each other since they share resources
-+in the parent node, and are thus children.
-+
-+Required subnodes:
-+- port0: contains the resources for ethernet port 0
-+- port1: contains the resources for ethernet port 1
-+
-+Required subnode properties:
-+- compatible: must be "cortina,gemini-ethernet-port"
-+- reg: must contain two register areas: the DMA/TOE memory and
-+ the GMAC memory area of the port
-+- interrupts: should contain the interrupt line of the port.
-+ this is nominally a level interrupt active high.
-+- resets: this must provide an SoC-integrated reset line for
-+ the port.
-+- clocks: this should contain a handle to the PCLK clock for
-+ clocking the silicon in this port
-+- clock-names: must be "PCLK"
-+
-+Optional subnode properties:
-+- phy-mode: see ethernet.txt
-+- phy-handle: see ethernet.txt
-+
-+Example:
-+
-+mdio-bus {
-+ (...)
-+ phy0: ethernet-phy@1 {
-+ reg = <1>;
-+ device_type = "ethernet-phy";
-+ };
-+ phy1: ethernet-phy@3 {
-+ reg = <3>;
-+ device_type = "ethernet-phy";
-+ };
-+};
-+
-+
-+ethernet@60000000 {
-+ compatible = "cortina,gemini-ethernet";
-+ reg = <0x60000000 0x4000>, /* Global registers, queue */
-+ <0x60004000 0x2000>, /* V-bit */
-+ <0x60006000 0x2000>; /* A-bit */
-+ syscon = <&syscon>;
-+ #address-cells = <1>;
-+ #size-cells = <1>;
-+ ranges;
-+
-+ gmac0: ethernet-port@0 {
-+ compatible = "cortina,gemini-ethernet-port";
-+ reg = <0x60008000 0x2000>, /* Port 0 DMA/TOE */
-+ <0x6000a000 0x2000>; /* Port 0 GMAC */
-+ interrupt-parent = <&intcon>;
-+ interrupts = <1 IRQ_TYPE_LEVEL_HIGH>;
-+ resets = <&syscon GEMINI_RESET_GMAC0>;
-+ clocks = <&syscon GEMINI_CLK_GATE_GMAC0>;
-+ clock-names = "PCLK";
-+ phy-mode = "rgmii";
-+ phy-handle = <&phy0>;
-+ };
-+
-+ gmac1: ethernet-port@1 {
-+ compatible = "cortina,gemini-ethernet-port";
-+ reg = <0x6000c000 0x2000>, /* Port 1 DMA/TOE */
-+ <0x6000e000 0x2000>; /* Port 1 GMAC */

-Subject: [PATCH 22/31] net: ethernet: Add a driver for Gemini gigabit ethernet
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The Gemini ethernet has been around for years as an out-of-tree
-patch used with the NAS boxen and routers built on StorLink
-SL3512 and SL3516, later Storm Semiconductor, later Cortina
-Systems. These ASICs are still being deployed and brand new
-off-the-shelf systems using it can easily be acquired.
-
-The full name of the IP block is "Net Engine and Gigabit
-Ethernet MAC" commonly just called "GMAC".
-
-The hardware block contains a common TCP Offload Enginer (TOE)
-that can be used by both MACs. The current driver does not use
-it.

-
-Setting it to muxmode 0 disables the slave interface:

-Subject: [PATCH 26/31] power: gemini-poweroff: Avoid spurious poweroff
-
-On the D-Link DIR-685 we get spurious poweroff from
-infrared. Since that block (CIR) doesn't even have a
-driver this can be safely ignored, we can revisit this
-code once we have a device supporting CIR.
-
-On the D-Link DNS-313 we get spurious poweroff from
-the power button. This appears to be an initialization
-issue: we need to enable the block (start the state
-machine) before we clear any dangling IRQ.
-
-This patch fixes both issues.

-Subject: [PATCH 29/31] usb: host: fotg2: add silicon clock handling
-
-When used in a system with software-controller silicon clocks,
-the FOTG210 needs to grab, prepare and enable the clock.
-This is needed on for example the Cortina Gemini, where the
-platform will by default gate off the clock unless the
-peripheral (in this case the USB driver) grabs and enables
-the clock.
