soc: fsl: dpio: register dpio irq handlers after dpio create

2020-04-17T14:11:48+00:00

[ Upstream commit fe8fe7723a3a824790bda681b40efd767e2251a7 ]

The dpio irqs must be registered when you can actually
receive interrupts, ie when the dpios are created.
Kernel goes through NULL pointer dereference errors
followed by kernel panic [1] because the dpio irqs are
enabled before the dpio is created.

commit f10e58a5d20e1cf3a39a842da92c9dd0c3c23849 upstream.

The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have odd sizeofs.

This produces many oopses with CONFIG_KASAN=y.

Fix by marking with __aligned(4).

[ Upstream commit 6f4ecbe284df5f22e386a640d9a4b32cede62030 ]

If only Tegra194 support is enabled, the tegra30_fuse_read() and
tegra30_fuse_init() function are not declared and cause a build failure.
Add Tegra194 to the preprocessor guard to make sure these functions are
available for Tegra194-only builds as well.

soc: qcom: rpmhpd: Set 'active_only' for active only power domains

commit 5d0d4d42bed0090d3139e7c5ca1587d76d48add6 upstream.

The 'active_only' attribute was accidentally never set to true for any
power domains meaning that all the code handling this attribute was
dead.

NOTE that the RPM power domain code (as opposed to the RPMh one) gets
this right.

Pull ARM SoC fixes from Olof Johansson:
 "I've been sitting on these longer than I meant, so the patch count is
  a bit higher than ideal for this part of the release. There's also
  some reverts of double-applied patches that brings the diffstat up a
  bit.

  With that said, the biggest changes are:

   - Revert of duplicate i2c device addition on two Aspeed (BMC)
     Devicetrees.

   - Move of two device nodes that got applied to the wrong part of the
     tree on ASpeed G6.

   - Regulator fix for Beaglebone X15 (adding 12/5V supplies)

   - Use interrupts for keys on Amlogic SM1 to avoid missed polls

  In addition to that, there is a collection of smaller DT fixes:

   - Power supply assignment fixes for i.MX6

   - Fix of interrupt line for magnetometer on i.MX8 Librem5 devkit

   - Build fixlets (selects) for davinci/omap2+

   - More interrupt number fixes for Stratix10, Amlogic SM1, etc.

   - ... and more similar fixes across different platforms

  And some non-DT stuff:

   - optee fix to register multiple shared pages properly

   - Clock calculation fixes for MMP3

   - Clock fixes for OMAP as well"
