[PATCH v2 0/3] ARM: dts: berlin: add PMU and twd's cpu mask and fix GPIO locations

[Jisheng Zhang]

These patches try to improve dts for berlin. One of them enables PMU support
to BG2Q and BG2CD SoCs. One of them adds the missing PPI cpu mask to twd timer
interrupts. The last one corrects the SM GPIOs' location for BG2Q SoC.

Changes since v1:
 - Adds some text to the log of the second commit
 - Adds the patch to fix SM GPIO locations

[PATCH v2 3/3] ARM: dts: berlin: correct BG2Q's SM GPIO location.

[Jisheng Zhang]

The gpio4 and gpio5 are in 0xf7fc0000 apb which is located in the SM domain.
This patch moves gpio4 and gpio5 to the correct location. This patch also
renames them as the following to match the names we internally used in
marvell:
	gpio4 -> sm_gpio1
	gpio5 -> sm_gpio0
	porte -> portf
	portf -> porte

This also matches what we did for BG2 and BG2CD's SM GPIO.

Jisheng,

please do not add unrelated patches to an existing patch set.

Anyway, applied to berlin/fixes. It will also be Cc'd to stable
from 3.16 onwards due to the broken gpio base address.

Thanks!

Sebastian

[PATCH v2 2/3] ARM: dts: berlin: add PPI cpu mask to twd timer interrupts

[Jisheng Zhang]

According to the gic binding document, "bits[15:8] PPI interrupt cpu
mask.  Each bit corresponds to each of the 8 possible cpus attached to
the GIC.  A bit set to '1' indicated the interrupt is wired to that
CPU." This patch wants to add the PPI cpu mask for completeness.
