+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 07/31] pinctrl: gemini: Fix GMAC groups
+
+The GMII groups need to be split across GMAC0 and GMAC1 since
+GMAC0 is always available but GMAC1 masks GPIO2 lines 0-7
+so we might want just one interface out.

+Subject: [PATCH 11/31] pinctrl: gemini: Support drive strength setting
+
+The Gemini pin controller can set drive strength for a few
+select groups of pins (not individually). Implement this
+for GMAC0 and 1 (ethernet ports), IDE and PCI.

+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

+bindings and modelling the two child ports as child devices
+under the parent ethernet controller device.

++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.

+The zeroday builder notices that since Usermode Linux does not

+
+As the driver is clearly using memory-mapped registers to access

+Subject: [PATCH 25/31] ARM: dts: Set D-Link DNS-313 SATA to muxmode 0
+
+This stops the driver from trying to probe the ATA slave
+interface. The vendor code enables the slave interface
+but the driver in the vendor tree does not make use of
+it.
+
+Setting it to muxmode 0 disables the slave interface:
+the hardware only has the master interface connected
+to the one harddrive slot anyways.
+
+Without this change booting takes excessive time, so it
+is very annoying to end users.

+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.

++This OTG-capable USB host controller is found in Cortina Systems
++Gemini and other SoC products.
++
++Required properties:
++- compatible: should be one of:
++  "faraday,fotg210"
++  "cortina,gemini-usb", "faraday,fotg210"
++- reg: should contain one register range i.e. start and length
++- interrupts: description of the interrupt line
++
++Optional properties:
++- clocks: should contain the IP block clock
++- clock-names: should be "PCLK" for the IP block clock
++
++Required properties for "cortina,gemini-usb" compatible:
++- syscon: a phandle to the system controller to access PHY registers
++
++Optional properties for "cortina,gemini-usb" compatible:
++- cortina,gemini-mini-b: boolean property that indicates that a Mini-B
++  OTH connector is in use
++- wakeup-source: see power/wakeup-source.txt
++
++Example for Gemini:
++
++usb@68000000 {
++	compatible = "cortina,gemini-usb", "faraday,fotg210";
++	reg = <0x68000000 0x1000>;
++	interrupts = <10 IRQ_TYPE_LEVEL_HIGH>;
++	clocks = <&cc 12>;
++	clock-names = "PCLK";
++	syscon = <&syscon>;
++	wakeup-source;
++};

+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.

+Subject: [PATCH 30/31] usb: host: fotg2: add Gemini-specific handling
+
+The Cortina Systems Gemini has bolted on a PHY inside the
+silicon that can be handled by six bits in a MISC register in
+the system controller.
+
+If we are running on Gemini, look up a syscon regmap through
+a phandle and enable VBUS and optionally the Mini-B connector.
+
+If the device is flagged as "wakeup-source" using the standard
+DT bindings, we also enable this in the global controller for
+respective port.

+Subject: [PATCH 31/31] ARM: dts: Add the FOTG210 USB host to Gemini
+
+This adds the FOTG210 USB host controller to the Gemini
+device trees. In the main SoC DTSI it is flagged as disabled
+and then it is selectively enabled on the devices that utilize
+it (these per-platform enablements are done on the out-of-tree
+OpenWrt patch set). It is not enabled on the Itian SquareOne
+NAS/router since this instead has a VIA host controller
+soldered on the PCI port, and can gate off these USB host
+controllers.
