[PATCH 0/6] Macchiatobin updates

[PATCH 0/6] Macchiatobin updates

[Russell King - ARM Linux]

This series, based upon the 4.12-rc6 backports branch in the MISL tree:
- adds a maintainer entry for the Macchiatobin board.
- adds GPIO interrupt support to the CP110s
- adds the pinmux entries
- corrects the 5V regulator GPIO entry
- adds support for the I2C mux (used for the SFP slots)
- adds PCIe support

All entries include the appropriate pinmux and GPIO configuration.

PCIe support has not been tested locally as I have no PCIe cards to
test with; this patch includes support for the PCIe reset GPIO signal.
If others can test that patch and let me know whether it works, I would
be most grateful.

[PATCH 5/6] arm64: dts: marvell: mcbin: add support for i2c mux

[Russell King]

The MACCHIATOBin board has a PCA9548 I2C mux for the SFP ports on
CP100 master I2C bus 1.  Add the DT description for it.

The first patch had been applied on mvebu/arm64-for-4.14.

Patch 2 to 6 had been applied on mvebu/dt64-for-4.14.

For the patch 4, I merged it with the patch that Thomas previously sent
because it was not in mainline yet even if it was on the backport
branch. The resulting patch is attached.

Subject: [PATCH] arm64: dts: marvell: fix USB3 regulator definition on
 MacchiatoBin

Due to the lack of GPIO support, the USB3 regulator definition was
left unfinished in the MacchiatoBin DT description. Now that GPIO
support is available, this commit adjusts the Device Tree to properly
describe the USB3 regulator.

Finally I tested the last patch with an Ethernet PCIe card it worked
well, but the reset part was not tested as I don't know how it should be
tested.

As soon as the v4.13-rc1 will be released then the branches will be rebased
on it and renamed mvebu/arm64 and mvebu/dt64.

Thanks,

Gregory
