bc6d5d7666 ARM: dts: at91: sama5d2: add m_can nodes
Add nodes to support the Controller Area Network(M_CAN) on SAMA5D2.
The version of M_CAN IP core is 3.1.0 (CREL = 0x31040730).

As said in SAMA5D2 datasheet, the CAN clock is recommended to use
frequencies of 20, 40 or 80 MHz. To achieve these frequencies,
PMC GCLK3 must select the UPLLCK(480 MHz) as source clock and
divide by 24, 12, or 6. So, the "assigned-clock-rates" property
has three options: 20000000, 40000000, and 80000000.
The "assigned-clock-parents" property should be referred to utmi
fixedly.

The MSBs [bits 31:16] of the CAN Message RAM for CAN0 and CAN1 are
default configured in 0x00200000. To avoid conflict with SRAM map
for PM, change them to 0x00210000 in the AT91Bootstrap via setting
the CAN Memories Address-based Register(SFR_CAN) of SFR.

ff964962a0 ARM: dts: at91: sama5d2 Xplained: set pin muxing for usb gadget and usb host
For USB gadget on port A (device mode):
- pin PA31 is configured as an input GPIO which triggers an interrupt when
  vbus is detected on USB port A.
- pin PB9 is configured as an output GPIO and set to low level so the
  board doesn't supply vbus to USB port A.

For USB host:
- pin PB10 is configured as an output GPIO and is active at high level.
  The ohci driver will activate this pin so the board supplies vbus to USB
  port B.
- pin PB9 should be configured as an output GPIO and active at high level
  to use to USB port A in host mode (conflicts with USB gadget).

34ff2dc769 ARM: dts: at91: sama5d2 Xplained: Correct the macb irq pinctrl node
All pinctrl nodes for the Atmel pinctrl controller need to have their
bias configuration explicitly defined. Otherwise, the pinctrl mapping
is not valid.

It works for now as the pinctrl driver proceeds even with invalid
mappings, but this can become an issue, if the pinctrl driver starts
to require valid mappings. Additionally, the pin is not protected from
being remapped later by an other driver.

There is an external 1kOhms pull-up to 3.3V, so no bias is required on
the Ethernet PHY's interrupt line.

6c482fd15d ARM: dts: at91: sama5d2 xplained: add phy address and IRQ for macb0
After 57a38effa5 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091)
the macb0 interface has difficulties to come back from power saving mode if
address not explicitly set up.
As the micrel phy on the board is actually configured to show up at address 1
we use this explicitly.
Adding the phy node and its real address fixes the issue.

The phy IRQ and associated pinmux node is also added.

6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.
