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.

In case if the host has higher align requirements for SG items, allow setting device-specific aligns for scatterlist items. Signed-off-by: Alexey Roslyakov <alexey.roslyakov@gmail.com>

#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 Signed-off-by: David Hsu <davidhsu@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Robert Nelson <robertcnelson@gmail.com>

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. https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/SRlnumt0LoMJ v4.1-rcX: added hack around CONFIG_OF_OVERLAY v4.2-rc3+: added if (of_machine_is_compatible("ti,am335x-bone")) so we do not break dual ethernet am335x devices Signed-off-by: Robert Nelson <robertcnelson@gmail.com>

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 [ 2591.915165] [<bf005310>] (eqep_get_position [tieqep]) from [<c08930d0>] (dev_attr_show+0x2c/0x58) More details: https://gist.github.com/pdp7/fe07082d23f2bfbc362c733a7b0aea72 BeagleBoard mailing list thread: https://groups.google.com/d/msg/beagleboard/_TdTH7oPEXE/MNvU-mY6DgAJ

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
