ARM: dts: logicpd-somlv: Fix interrupt on mmc3_dat1

2018-12-17T08:38:31+00:00

[ Upstream commit 3d8b804bc528d3720ec0c39c212af92dafaf6e84 ]

The interrupt on mmc3_dat1 is wrong which prevents this from
appearing in /proc/interrupts.

ARM: 8767/1: add support for building ARM kernel with clang

2018-12-05T18:42:41+00:00

(commit c1c386681bd73c4fc28eb5cc91cf8b7be9b409ba upstream)

Use cc-options call for compiler options which are not available
in clang. With this patch an ARMv7 multi platform kernel can be
successfully build using clang (tested with version 5.0.1).

ARM: dts: exynos: Mark 1 GHz CPU OPP as suspend OPP on Exynos5250

2018-11-13T19:16:54+00:00

commit 645b23da6f8b47f295fa87051335d41d139717a5 upstream.

1 GHz CPU OPP is the default boot value for the Exynos5250 SOC, so mark it
as suspend OPP. This fixes suspend/resume on Samsung Exynos5250 Snow
Chomebook, which was broken since switching to generic cpufreq-dt driver
in v4.3.

ARM: dts: exynos: Convert exynos5250.dtsi to opp-v2 bindings

2018-11-13T19:16:54+00:00

commit eb9e16d8573e243f8175647f851eb5085dbe97a4 upstream.

Convert Exynos5250 to OPP-v2 bindings. This is a preparation to add proper
support for suspend operation point, which cannot be marked in opp-v1.

arm: dts: exynos: Add missing cooling device properties for CPUs

2018-11-13T19:16:54+00:00

commit 672f33198bee21ee91e6af2cb8f67cfc8bc97ec1 upstream.

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Add such missing properties.

Fix other missing properties (clocks, OPP, clock latency) as well to
make it all work.

ARM: dts: exynos: Remove "cooling-{min|max}-level" for CPU nodes

commit cd6f55457eb449a388e793abd676e3a5b73510bc upstream.

The "cooling-min-level" and "cooling-max-level" properties are not
parsed by any part of the kernel currently and the max cooling state of
a CPU cooling device is found by referring to the cpufreq table instead.

Remove the unused properties from the CPU nodes.

ARM: dts: imx53-qsb: disable 1.2GHz OPP

[ Upstream commit eea96566c189c77e5272585984eb2729881a2f1d ]

The maximum CPU frequency for the i.MX53 QSB is 1GHz, so disable the
1.2GHz OPP. This makes the board work again with configs that have
cpufreq enabled like imx_v6_v7_defconfig on which the board stopped
working with the addition of cpufreq-dt support.

ARM: 8677/1: boot/compressed: fix decompressor header layout for v7-M

2018-11-10T15:42:48+00:00

[ Upstream commit 06a4b6d009a1b74a6ec46c5418b46cc53a79fcb8 ]

As reported by Patrice, the header layout of the decompressor is
incorrect when building for v7-M. In this case, the __nop macro
resolves to 'mov r0, r0', which is emitted as a narrow encoding,
resulting in the header data fields to end up at lower offsets than
required.

Given the variety of targets we need to support with the same code,
the startup sequence is a bit of a jumble, and uses instructions
and macros whose encoding widths cannot be specified (badr), or only
exist in a narrow encoding (bx)

So force the use of a wide encoding in __nop, and replace the start
sequence with a simple jump to the label marking the start of code,
preceded by a Thumb2 mode switch if required (using explicit wide
encodings where appropriate). The label itself can be moved to the
start of code [where it belongs] due to the larger range of branch
instructions as compared to adr instructions.

ARM: dts: bcm283x: Reserve first page for firmware

2018-11-10T15:42:47+00:00

[ Upstream commit b0804ed0cadd7e38d94d2f15cdcc0d9695818856 ]

The Raspberry Pi startup stub files for multi-core BCM283X processors
make the secondary CPUs spin until the corresponding mailbox is
written. These stubs are loaded at physical address 0x00000xxx (as seen
by the ARMs), but this page will be reused by the kernel unless it is
explicitly reserved, causing the waiting cores to execute random code.

Use the /memreserve/ Device Tree directive to mark the first page as
off-limits to the kernel.
