ARM: dts: armada-38x: Fix irq type for pca955

2017-08-11T16:08:48+00:00

commit 8d4514173211586c6238629b1ef1e071927735f5 upstream.

As written in the datasheet the PCA955 can only handle low level irq and
not edge irq.

Without this fix the interrupt is not usable for pca955: the gpio-pca953x
driver already set the irq type as low level which is incompatible with
edge type, then the kernel prevents using the interrupt:

"irq: type mismatch, failed to map hwirq-18 for
/soc/internal-regs/gpio@18100!"

ARM: dts: n900: Mark eMMC slot with no-sdio and no-sd flags

2017-08-07T02:19:44+00:00

[ Upstream commit 4cf48f1d7520a4d325af58eded4d8090e1b40be7 ]

Trying to initialize eMMC slot as SDIO or SD cause failure in n900 port of
qemu. eMMC itself is not detected and is not working.

Real Nokia N900 harware does not have this problem. As eMMC is really not
SDIO or SD based such change is harmless and will fix support for qemu.

ARM: dts: BCM5301X: Correct GIC_PPI interrupt flags

2017-07-05T12:37:16+00:00

commit 0c2bf9f95983fe30aa2f6463cb761cd42c2d521a upstream.

GIC_PPI flags were misconfigured for the timers, resulting in errors
like:
[    0.000000] GIC: PPI11 is secure or misconfigured

Changing them to being edge triggered corrects the issue

ARM: dts: imx6dl: Fix the VDD_ARM_CAP voltage for 396MHz operation

2017-06-17T04:39:35+00:00

commit 46350b71a09ccf3573649e03db55d4b61d5da231 upstream.

Table 8 from MX6DL datasheet (IMX6SDLCEC Rev. 5, 06/2015):
http://cache.nxp.com/files/32bit/doc/data_sheet/IMX6SDLCEC.pdf

states the following:

"LDO Output Set Point (VDD_ARM_CAP) = 1.125 V minimum for operation
up to 396 MHz."

So fix the entry by adding the 25mV margin value as done in the other
entries of the table, which results in 1.15V for 396MHz operation.

commit 0c18927f51f4d390abdcf385bff5f995407ee732 upstream.

Current U-Boot enables the display already. Marking the regulator as

commit b1708b72a0959a032cd2eebb77fa9086ea3e0c84 upstream.

The dmas/dma-names properties are added to the UART nodes. Note that additional
properties are needed to enable them at the board level: check bindings for
details.
