brcmfmac: add new dt entries for SG SDIO settings
beaad37 
There are 3 fields in SDIO settings (quirks) to workaround some of
the SG SDIO host particularities, i.e higher align requirements for
SG items.
All coding is done the long time ago, but there is no way to change the
driver behavior without patching the kernel.
Add missing devicetree entries.

@RobertCNelson
pwm: Create device class for pwm channels
a4d02d1 
#https://lkml.org/lkml/2016/6/14/967

Pwm channels don't send uevents when exported, this change adds the
channels to a pwm class and set their device type to pwm_channel so
uevents are sent.

To do this properly, the device names need to change to uniquely
identify a channel.  This change is from pwmN to pwm-(chip->base):N

I have encountered the same issue(s) on A6A boards.

I couldn't find a patch,  so I wrote this patch to update the device tree
in the davinci_mdio driver in the 3.15.1 tree, it seems to correct it. I
would welcome any input on a different approach.

tieqep: fix unhandled fault on eQEP register access
b83a8c1 
Call pm_runtime_get_sync() at the beginning of any functions that will
read or write to the memory mapped eQEP registers.  This is to ensure
that the eQEP peripheral is running and its clock is enabled.

Before this patch, an attempt to read the position file via sysfs would
results in a segmentation fault.  The kernel log would be contain this
error:

[ 2591.653471] Unhandled fault: external abort on non-linefetch (0x1028) at 0xfa304180

ti_am335x_tsc.c driver

------=_Part_422_1349561576.1515022447432
Content-Type: text/plain; charset="UTF-8"

Hello all,

The TI touch screen driver does not work _right_ with the libts-bin package
in the jessie image.

$ cat /etc/dogtag
BeagleBoard.org Debian Image 2018-01-01

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 8.10 (jessie)
Release:        8.10
Codename:       jessie

$ dpkg -l | grep  libts-bin
ii  libts-bin                             1.14-1rcnee0~jessie+20171122
                      armhf        touch screen library utilities

$ sudo ts_calibrate
ts_setup: No such file or directory

It is possible to make it work by setting the TSLIB_TSDEVICE environment
variable:

$ sudo su
# export TSLIB_TSDEVICE=/dev/input/event2
# ts_calibrate

But, that's a bit of a pain since the environment variable always needs to
be set in order to use the touchscreen.

It appears that this version of the utilities uses the INPUT_PROP_DIRECT
propbit to automatically detect which /dev/input/event device is the
touchscreen.

It looks like the following is the only change needed to make it work.

Unfortunately, I don't have currently have a way to build a custom kernel
for the BeagleBone in order to test it. If there is anyone that could I
would
appreciate it.

Regards,
Hartley

btrfs: avoid NULL pointer dereference if no valid extent tree
aee5f69 
[ Upstream commit 6aecd91 ]

[BUG]

   </TASK>

[CAUSE]
The reproducer is using a corrupted image where extent tree root is
corrupted, thus forcing to use "rescue=all,ro" mount option to mount the
image.

Then it triggered a scrub, but since scrub relies on extent tree to find
where the data/metadata extents are, scrub_find_fill_first_stripe()
relies on an non-empty extent root.

But unfortunately scrub_find_fill_first_stripe() doesn't really expect
an NULL pointer for extent root, it use extent_root to grab fs_info and
triggered a NULL pointer dereference.

[FIX]
Add an extra check for a valid extent root at the beginning of
scrub_find_fill_first_stripe().

The new error path is introduced by 42437a6 ("btrfs: introduce
mount option rescue=ignorebadroots"), but that's pretty old, and later
commit b979547 ("btrfs: scrub: introduce helper to find and fill
sector info for a scrub_stripe") changed how we do scrub.

So for kernels older than 6.6, the fix will need manual backport.
