ARM: omap2+: am437x: rollback to use omap3_gptimer_timer_init()

2017-01-15T12:42:57+00:00

commit f86a2c875fd146d9b82c8fdd86d31084507bcf4c upstream.

The commit 55ee7017ee31 ("arm: omap2: board-generic: use
omap4_local_timer_init for AM437x") unintentionally changes the
clocksource devices for AM437x from OMAP GP Timer to SyncTimer32K.

Unfortunately, the SyncTimer32K is starving from frequency deviation
as mentioned in commit 5b5c01359152 ("ARM: OMAP2+: AM43x: Use gptimer
as clocksource") and, as reported by Franklin [1], even its monotonic
nature is under question (most probably there is a HW issue, but it's
still under investigation).

Taking into account above facts It's reasonable to rollback to the use
of omap3_gptimer_timer_init().

ARM: OMAP4+: Fix bad fallthrough for cpuidle

2017-01-15T12:42:57+00:00

commit cbf2642872333547b56b8c4d943f5ed04ac9a4ee upstream.

We don't want to fall through to a bunch of errors for retention
if PM_OMAP4_CPU_OSWR_DISABLE is not configured for a SoC.

ARM: OMAP5: Fix build for PM code

2017-01-15T12:42:57+00:00

commit da6d5993bf951846956903bee4f0eafd918250db upstream.

It's CONFIG_SOC_OMAP5, not CONFIG_ARCH_OMAP5. Looks like make randconfig
builds have not hit this one yet.

ARM: OMAP5: Fix mpuss_early_init

2017-01-15T12:42:57+00:00

commit 8a8be46afeaa47aed1debe7e9b18152f9826a6b7 upstream.

We need to properly initialize mpuss also on omap5 like we do on omap4.
Otherwise we run into similar kexec problems like we had on omap4 when
trying to kexec from a kernel with PM initialized.

ARM: zynq: Reserve correct amount of non-DMA RAM

2017-01-15T12:42:56+00:00

commit 7a3cc2a7b2c723aa552028f4e66841cec183756d upstream.

On Zynq, we haven't been reserving the correct amount of DMA-incapable
RAM to keep DMA away from it (per the Zynq TRM Section 4.1, it should be
the first 512k). In older kernels, this was masked by the
memblock_reserve call in arm_memblock_init(). Now, reserve the correct
amount excplicitly rather than relying on swapper_pg_dir, which is an
address and not a size anyway.

ARM: pxa: fix pxa25x interrupt init

2017-01-15T12:42:56+00:00

commit e413bd33ac44b6d0bebc0ef2ac19cbe7558a7303 upstream.

In the device-tree case, the root interrupt controller cannot be
accessed through the 6th coprocessor, contrary to pxa27x and pxa3xx
architectures.

Fix it to behave as in non-devicetree builds.

crypto: arm/aes-ce - fix for big endian

2017-01-12T10:39:33+00:00

commit 58010fa6f71c9577922b22e46014b95a4ec80fa0 upstream.

The AES key schedule generation is mostly endian agnostic, with the
exception of the rotation and the incorporation of the round constant
at the start of each round. So implement a big endian specific version
of that part to make the whole routine big endian compatible.

commit 0cff18cbab4f55581d9da86e4286655d9723d7d2 upstream.

The 2 USB host ports are directly tied to the 2 USB hosts in the SoC.
The 2 host pairs were already enabled, but the USB PHY wasn't.
VBUS on the 2 ports are always on.
