gemini: add 4.14 support

Browse Source 
This adds the patches to get fairly complete Gemini support
using kernel v4.14. It is mainly a backport of patches from
kernel v4.16 with omissions of things like graphics that require
substantial changes and will be better handled once we move
to the v4.16 kernel proper.
On top of this are some WIP patches for USB support.

Tested on Raidsonic NAS4220B and D-link DNS-313.

ChangeLog v4->v5:
- Fix ethernet single gmac usecase
- Fix USB reset (patch from Hans)
- Fix Raidsonic ethernet skew delay
- Fix kernel config (bridge, squashfs, jffs2, usb)
- Disable second usb port on Raidsonic board until fotg210_hcd is fixed

ChangeLog v3->v4:
- Make sure to use tabs rather than spaces in base-files.
- Use the dns313 image tool from the firmware-utils.
- Break out the addition of the v4.14 patches and the removal
  of the v4.4 patches to separate (big) patches.

ChangeLog v2->v3:
- Update the kernel config as indicated by Hauke Martens:
- Regenerate again after rebasing using kernel_oldconfig
  dropping a few optimization settings that are now generic
- Drop CFG80211 stuff (module)
- Drop CIFS stuff (module)
- Drop MAC80211 (module)
- Drop wireless drivers (module)
- Enabled OverlayFS
- Added proper DNS-313 boot image generation with the special
  file header tool.
- Disable CMA in the kernel
- Enable LZMA compression of the kernel
- Consequently name the nas4220b images nas4220b
- Update preinit MAC detection script to handle also DNS-313
- Add board.d/03_hdparm to set the disk to spin down after
  1 minute by default, if we have the hdparm tool installed

ChangeLog v1->v2:
- Processed config through kernel_oldconfig
- Processed patches through make target/linux/{clean,refresh} V=99

Date: Sat, 28 Oct 2017 15:37:17 +0200
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.

From e7759c44e0c20dd6b5a259300acdc7350ea6dd32 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Mon, 6 Nov 2017 21:27:34 +0100
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 12/31] ARM: dts: Add ethernet PHYs to the a bunch of Geminis
These Gemini boards have Ethernet PHY on GPIO bit-banged
MDIO, clearly defined in the corresponding OpenWRT
ethernet patches since ages. Add them in accordance with
the OpenWRT patch so we can use them when we add ethernet
support.

This adds a basic device tree for the D-Link DNS-313

fan so we add a thermal zone for the chassis in the
device tree based on information from the product.

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 18/31] watchdog: gemini/ftwdt010: rename driver and symbols
This renames all the driver files and symbols for the Gemini
watchdog to FTWDT010 as it has been revealed that this IP block
is a generic watchdog timer from Faraday Technology used in
several SoC designs.
Select this driver by default for the Gemini, it is a sensible
driver to always have enabled.

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.

+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 {

it can enable.
As the driver is clearly using memory-mapped registers to access
the network adapter, we add depends on HAS_IOMEM to solve this
problem.

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.

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.

USB maintainers: I will merge this through the ARM SoC tree,
