The card detect GPIO is using IRQ_TYPE_LEVEL_LOW in the GPIO flag cells
but this defined constant is meant to be used for a IRQ and not a GPIO.
So instead use GPIO_ACTIVE_LOW that seems to be the original intention.

The DRA7xx family of SOCs have two IPUs and one DSP processor
subsystems in common. The IOMMU DT nodes have been added for
these processor subsystems, and have been disabled by default.
These MMUs are very similar to those on OMAP4 and OMAP5, with
the only difference being the presence of a second MMU within
the DSP subsystem for the EDMA port. The DSP IOMMUs also need
an additional 'ti,syscon-mmuconfig' property compared to the
IPU IOMMUs.
NOTE: The enabling of these nodes is left to the respective
board dts files.

Add a syscon node for this module for the DSP2 processor

Originally, all the SoC PHY rails were supplied by LDO3. However, as a

extreme load conditions. Hence the PHY rails are split between two
different LDOs. Update the related node as a result
LDO3/VDDA_1V8_PHYA supplies vdda_usb1, vdda_usb2, vdda_sata, vdda_usb3
LDO4/VDDA_1V8_PHYB supplies vdda_pcie1, vdda_pcie0, vdda_hdmi, vdda_pcie
NOTE: We break compatibility with pre-production boards with this change
since, the PMIC LDO4 is disabled at OTP level.
The new configuration is the plan of record and all pre-production
boards are supposed to be replaced with the latest boards matching the
mentioned configuration.
Some very few 10 something boards have been created and
stopped production till the latest modifications were done (PMIC USB

Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull late ARM SoC updates from Kevin Hilman:
"This is a collection of a few late fixes and other misc stuff that had
dependencies on things being merged from other trees.
The bulk of the changes are for samsung/exynos SoCs for some changes
that needed a few minor reworks so ended up a bit late. The others
are mainly for qcom SoCs: a couple fixes and some DTS updates"

When loading x86 64bit kernel above 4GiB with patched grub2, got kernel
gunzip error.

the new buffer is at 0x46fe000000ULL, decompressor_gzip is using
0xffffffb901ffffff as out_len. gunzip in lib/zlib_inflate/inflate.c cap
that len to 0x01ffffff and decompress fails later.
We could hit this problem with crashkernel booting that uses kexec loading
kernel above 4GiB.
We have decompress_* support:
1. inbuf[]/outbuf[] for kernel preboot.
2. inbuf[]/flush() for initramfs
3. fill()/flush() for initrd.
This bug only affect kernel preboot path that use outbuf[].
Add __decompress and take real out_buf_len for gunzip instead of guessing
wrong buf size.
Fixes: 1431574a1c (lib/decompressors: fix "no limit" output buffer length)

Use stdout-path so that we don't have to put the console on the
kernel command line.
