e3770594c4 ARM: dts: add EBI2 to the Qualcomm MSM8660 DTSI
This adds the external bus interface EBI2 to the MSM8660 device
tree, albeit with status = "disabled" so that devices actually
using EBI2 can turn it on if needed.

dcf5907e0e ARM: dts: MSM8660 remove flags from SPMI/MPP IRQs
The Qualcomm SPMI GPIO and MPP lines are problematic: the
are fetched from the main MFD driver with platform_get_irq()
which means that at this point they will all be assigned the
flags set up for the interrupts in the device tree.

That is problematic since these are flagged as rising edge
and an this point the interrupt descriptor is assigned a
rising edge, while the only thing the GPIO/MPP drivers really
do is issue irq_get_irqchip_state() on the line to read it
out and to provide a .to_irq() helper for *other* IRQ
consumers.

If another device tree node tries to flag the same IRQ
for use as something else than rising edge, the kernel
irqdomain core will protest like this:

  type mismatch, failed to map hwirq-NN for <FOO>!

Which is what happens when the device tree defines two
contradictory flags for the same interrupt line.

To work around this and alleviate the problem, assign 0
as flag for the interrupts taken by the PM GPIO and MPP
drivers. This will lead to the flag being unset, and a
second consumer requesting rising, falling, both or level
interrupts will be respected. This is what the qcom-pm*.dtsi
files already do.

Switched to using the symbolic name IRQ_TYPE_NONE so that
we get this more readable.

This misconfiguration was caused by a copy/pasting the
APQ8064 set-up, the latter has been fixed in a separate
patch.

Tested with one of the SPMI GPIOs: after this I can
successfully request one of these GPIOs as falling edge
from the device tree.

1758b35808 ARM: dts: move the fixed MMC regulator to SURF board
There is currently a fixed regulator in the .dtsi file for
the MSM8660 chipset, used by the SURF board. We want to define
real regulators for a board using this chipset, so push the fixed
regulator down to the SURF board which is the only user.

e20fd3364c ARM: dts: fix the MSM8660 RTC base address
The RTC was defined on 0x11d but on the MSM8660/APQ8060 it is
actually on 0x1e8. We were saved by the fact that the driver does
not use the reg parameter: instead it uses the compatible string
to figure out where the RTC is.

2ef7d5f342 ARM, ARM64: dts: drop "arm,amba-bus" in favor of "simple-bus"
The compatible string "simple-bus" is well defined in ePAPR, while
I see no documentation for the "arm,amba-bus" arnywhere in ePAPR or
Documentation/devicetree/.

DT is also used by other projects than Linux kernel.  It is not a
good idea to rely on such an unofficial binding.

This commit
  - replaces "arm,amba-bus" with "simple-bus"
  - drops "arm,amba-bus" where it is used along with "simple-bus"
