The invalid value of #address-cells in the imx6 pcie host controller node
causes of_irq_parse_raw() to incorrectly advance through an interrupt-map
table of more than one interrupt. We also take the opportunity to drop the
unused #size-cells here.
This patch resolves this issue and allows proper interrupt mapping for an
imx6 pcie host connected to a P2P bridge when using legacy interrupts.

As spdif driver will register SPDIF clock to regmap, regmap will do
clk_prepare in init function, so SPDIF clock is prepared in probe, then its
root clock (pll clock) is prepared also, which cause the arm can't enter
low power mode.
Add SPDIF_GCLK in clock tree which share same gate bits with SPDIF clock.
Its root clock is ipg clock, and register it to regmap, then the issue can be
fixed.

- Add usbphy_nop, hsic uses nop phy driver
- Add anatop phandle, hsic needs to access anatop register to
change osc clock for different boards
- Add phy_type, hsic needs to config PHY parameters at portsc
- For imx6q-arm2 board, hsic has pin conflict with ethernet, we create a

please make sure keep the line of data and strobe unchanged between board

The ocotp also plays as a fuse device beside the system controller we
already have in device tree. Let's add a device node for the fuse
device for imx6qdl and imx6sl.
While at it, the patch also drops "fsl,imx6q-ocotp" and
"fsl,imx6sl-ocotp" from system controller compatible string, since
it's not used, and use node name ocotp-ctrl and ocotp-fuse for system
controller and fuse device respectively.

Starting from IMX6, the flexcan stop mode control bits is SoC specific,
move it out of IP driver and parse it from devicetree.
It's good from maintain perspective and can avoid adding too many SoC
specifi bits in driver but with no IP changes when the IMX SoC series
keep growing.

The PGC that is part of GPC controls isolation and power sequencing of the
power domains. The PU power domain will be handled by the generic pm domain
framework. It needs a phandle to the PU regulator to turn off power when
the domain is disabled, and a list of phandles to all clocks that must be
enabled during powerup for reset propagation.

Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that
boards that share the same pinctrl setting do not have to define it time
and time again in <board>.dts. However, along with the devices and use
cases being added continuously, the pinctrl setting nodes under iomuxc
becomes more than expected. This bloats device tree blob for particular
board unnecessarily since only a small subset of those pinctrl setting
nodes will be used by the board. It impacts not only the DTB file size
but also the run-time device tree lookup efficiency.
The patch moves all the pinctrl data into individual boards as needed.
With the changes, the pinctrl setting nodes becomes local to particular
board, and it makes no sense to continue numbering the setting for
given peripheral. Thus, all the pinctrl phandler name gets updated to
have only peripheral name in there.

The spdif "rxtx5" clock option is being set to ipg clk (62) by mistake.
This causes an incorrect time keeping when spdif driver is running,
because ipg is ancestor clock for clocksource while spdif driver will
change the rate of this clock in certain circumstance. Before the
correct clock for "rxtx5" option can be supplied, let's disable this
option for now by filling a dummy clock for it.
