net: dsa: qca8k: Add QCA8334 binding documentation

2018-08-03T05:55:26+00:00

commit 218bbea11a777c156eb7bcbdc72867b32ae10985 upstream.

Add support for the four-port variant of the Qualcomm QCA833x switch.

The CPU port default link settings can be reconfigured using
a fixed-link sub-node.

dt-bindings: net: meson-dwmac: new compatible name for AXG SoC

2018-08-03T05:55:24+00:00

[ Upstream commit 7e5d05e18ba1ed491c6f836edee7f0b90f3167bc ]

We need to introduce a new compatible name for the Meson-AXG SoC
in order to support the RMII 100M ethernet PHY, since the PRG_ETH0
register of the dwmac glue layer is changed from previous old SoC.

dt-bindings: pinctrl: meson: add support for the Meson8m2 SoC

2018-08-03T05:55:24+00:00

[ Upstream commit 03d9fbc39730b3e6b2e7047dc85f0f70de8fb97d ]

The Meson8m2 SoC is a variant of Meson8 with some updates from Meson8b
(such as the Gigabit capable DesignWare MAC).
It is mostly pin compatible with Meson8, only 10 (existing) CBUS pins
get an additional function (four of these are Ethernet RXD2, RXD3, TXD2
and TXD3 which are required when the board uses an RGMII PHY).
The AOBUS pins seem to be identical on Meson8 and Meson8m2.

arm64: Add 'ssbd' command-line option

2018-07-22T12:27:41+00:00

commit a43ae4dfe56a01f5b98ba0cb2f784b6a43bafcc6 upstream.

On a system where the firmware implements ARCH_WORKAROUND_2,
it may be useful to either permanently enable or disable the
workaround for cases where the user decides that they'd rather
not get a trap overhead, and keep the mitigation permanently
on or off instead of switching it on exception entry/exit.

In any case, default to the mitigation being enabled.

lib/vsprintf: Remove atomic-unsafe support for %pCr

2018-07-03T09:23:06+00:00

commit 666902e42fd8344b923c02dc5b0f37948ff4f225 upstream.

"%pCr" formats the current rate of a clock, and calls clk_get_rate().
The latter obtains a mutex, hence it must not be called from atomic
context.

Remove support for this rarely-used format, as vsprintf() (and e.g.
printk()) must be callable from any context.

Any remaining out-of-tree users will start seeing the clock's name
printed instead of its rate.

dmaengine: mv_xor_v2: Fix clock resource by adding a register clock

2018-05-30T05:50:36+00:00

[ Upstream commit 3cd2c313f1d618f92d1294addc6c685c17065761 ]

On the CP110 components which are present on the Armada 7K/8K SoC we need
to explicitly enable the clock for the registers. However it is not
needed for the AP8xx component, that's why this clock is optional.

With this patch both clock have now a name, but in order to be backward
compatible, the name of the first clock is not used. It allows to still
use this clock with a device tree using the old binding.

dm thin: fix documentation relative to low water mark threshold

2018-05-30T05:50:20+00:00

[ Upstream commit 9b28a1102efc75d81298198166ead87d643a29ce ]

Fixes:
1. The use of "exceeds" when the opposite of exceeds, falls below,
was meant.
2. Properly speaking, a table can not exceed a threshold.

It emphasizes the important point, which is that it is the userspace
daemon's responsibility to check for low free space when a device
is resumed, since it won't get a special event indicating low free
space in that situation.
