      ARM: dts: MSM8064 remove flags from SPMI/MPP IRQs · ca88696e
      由 Linus Walleij 提交于 
      The Qualcomm PMIC 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.

      device-tree: aqp8064.dtsi: Remove usb phy dr_mode = "host" · 3f874a44
      由 John Stultz 提交于 
      Most 8064 devices have micro-usb ports for phy1, so setting
the dr_mode to host here seems incorrect.

Leaving it unspecified should default to otg, and then
any boards that wish to specify something else, can
override it in their dts file.
