7c7da40da1 Input: uinput - add compat ioctl number translation for UI_*_FF_UPLOAD
In the case of compat syscall ioctl numbers for UI_BEGIN_FF_UPLOAD and
UI_END_FF_UPLOAD need to be adjusted before being passed on
uinput_ioctl_handler() since code built with -m32 will be passing
slightly different values. Extend the code already covering
UI_SET_PHYS to cover UI_BEGIN_FF_UPLOAD and UI_END_FF_UPLOAD as well.

22c58fd70c ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms.
 Major themes this release:
 
  - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
  - Moving some of the ep93xx headers around to get it closer to multiplatform enabled.
  - Cleanups of Davinci
 
 This tag also contains a few patches that were queued up as fixes before
 5.1 but I didn't get sent in before release.

b283d0c353 Input: eeti_ts - read hardware state once after wakeup
For systems in which the touch IRQ is acting as wakeup source, and that do
not support level-driven interrupts, the interrupt controller might not
latch the GPIO IRQ during sleep. In such cases, the interrupt will never
occur again after resume, hence the touch screen appears dead.

To fix this, check for the assertion of the attn gpio, and read form the
controller once in the resume path to read the hardware status and
to arm the IRQ again.

Introduce a mutex to guard eeti_ts_read() against parallel invocations
from different contexts.

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/input/serio/libps2.c: In function ‘ps2_handle_ack’:
drivers/input/serio/libps2.c:407:6: warning: this statement may fall through [-Wimplicit-fallthrough=]

  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

Add initial support for the AT42QT1050 (QT1050) device. The device
supports up to five input keys, dependent on the mode. Since it adds only
the initial support, the "1 to 4 keys plus Guard Channel" mode isn't
supported.

c5bf68fe0c *: convert stream-like files from nonseekable_open -> stream_open
Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af34
("fs: stream_open - opener for stream-like files so that read and write
can run simultaneously without deadlock"), search and convert to
stream_open all in-kernel nonseekable_open users for which read and
write actually do not depend on ppos and where there is no other methods
in file_operations which assume @offset access.

I've verified each generated change manually - that it is correct to convert -
and each other nonseekable_open instance left - that it is either not correct
to convert there, or that it is not converted due to current stream_open.cocci
limitations. The script also does not convert files that should be valid to
convert, but that currently have .llseek = noop_llseek or generic_file_llseek
for unknown reason despite file being opened with nonseekable_open (e.g.
drivers/input/mousedev.c)

Among cases converted 14 were potentially vulnerable to read vs write deadlock
(see details in 10dce8af34):

and the rest were just safe to convert to stream_open because their read and
write do not use ppos at all and corresponding file_operations do not
have methods that assume @offset file access(*):

(*) This second group also contains cases with read/write deadlocks that
stream_open.cocci don't yet detect, but which are still valid to convert to

67e38f578a ARM: ep93xx: move pinctrl interfaces into include/linux/soc
ep93xx does not have a proper pinctrl driver, but does things
ad-hoc through mach/platform.h, which is also used for setting
up the boards.

To avoid using mach/*.h headers completely, let's move the interfaces
into include/linux/soc/. This is far from great, but gets the job
done here, without the need for a proper pinctrl driver.

dfb6db007a ARM: ep93xx: keypad: stop using mach/platform.h
We can communicate the clock rate using platform data rather than setting
a flag to use a particular value in the driver, which is cleaner and
avoids the dependency.

No platform in the kernel currently defines the ep93xx keypad device
structure, so this is a rather pointless excercise.  Any out of tree
users are probably dead now, but if not, they have to change their
platform code to match the new platform_data structure.

ecdf3a9658 Input: evdev - use struct_size() in kzalloc() and vzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable size is not necessary, hence
it is removed.

This code was detected with the help of Coccinelle.

afe6fe7036 ARM: SoC: late updates for linux-5.1
Here are two branches that came relatively late during the linux-5.0
 development cycle and have dependencies on the other branches:
 
 - On the TI OMAP platform, the CPSW Ethernet PHY mode selection driver
   is being replaced, this puts the final pieces in place
 
 - On the DaVinci platform, the interrupt handling code in arch/arm
   gets moved into a regular device driver in drivers/irqchip.
 
 Since they both had some time in linux-next after the 5.0-rc8
 release, I'm sending them along with the other updates.

Convert string compares of DT node names to use of_node_name_eq helper

property as it is the rare case where the 'name' property and node name

pointer.

While at it, convert the open coded loop to use for_each_child_of_node().

 - a few drivers have been switched to set_brightness_blocking() call
   because they either were sleeping the their set_brightness()

43bcd820bd Input: synaptics_i2c - remove redundant spinlock
Remove a leftover spinlock.

This was required back when mod_delayed_work() did not exist, and had to
be implemented with a cancel + queue. See commit e7c2f96744
("workqueue: use mod_delayed_work() instead of __cancel + queue")

schedule_delayed_work() and mod_delayed_work() can now be used
concurrently. So the spinlock is no longer needed.

Turns out this is not such a great idea. Once the SP clock is disabled,
it's not sufficient to just enable in order to bring the SP core back up.

It seems that the kernel has no business managing this clock. Just let
the firmware keep it enabled.

This reverts commit ed22cee91a.

Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module and
the dependent module is built-in.  The 'depends on RASPBERRYPI_FIRMWARE' by
itself prevents the touchscreen driver from being built-in when the
firmware is configured as a module.  However, the '|| COMPILE_TEST' still
allows it unless we explicitly prevent that configuration with
'|| (RASPBERRYPI_FIRMWARE=n && COMPILE_TEST)'.

it too is a push-button and not a slider/switch.

Further evidence can be found in the HUT extension HUTRR52 from Microsoft
which adds rotation lock support to the HUT, which describes 2 different
usages: "0xC9 System Display Rotation Lock Button" and
"0xCA System Display Rotation Lock Slider Switch" note that switch is seen
as a separate thing here and the non switch wording is an exact match for
the "Windows-compatible button array" spec wording.

TL;DR: our current mapping of the 5th GPIO to SW_ROTATE_LOCK is wrong
because the 5th GPIO is for a push-button not a switch.

This commit fixes this by maping the 5th GPIO to KEY_ROTATE_LOCK_TOGGLE.

39be9b6d04 Input: soc_button_array - add usage-page 0x01 usage-id 0xca mapping
The ACPI0011 _DSD button descriptor on a CHT based Intel Compute Sticks
contains a mapping for usage-page 0x01 usage-id 0xca.

As described in hutrr52_system_display_rotation_lock_controls_0.pdf this
should be mapped as a "System Display Rotation Lock Slider Switch", this
commit adds support for this, silencing the following warning:

dmesg reports that "Your touchpad (PNP: SYN3052 SYN0100 SYN0002 PNP0f13)
says it can support a different bus."

I've tested the offered psmouse.synaptics_intertouch=1 with 4.18.x and
4.19.x and it seems to work well. No problems seen with suspend/resume.

Also, it appears that RMI/SMBus mode is actually required for 3-4 finger
multitouch gestures to work -- otherwise they are not reported at all.

Information from dmesg in both modes:

The current implementation of elan_i2c is known to not support those
2 laptops.

A proper fix is to tweak both elantech and elan_i2c to transmit the
correct information from PS/2, which would make a bad candidate for
stable.

So to give us some time for fixing the root of the problem, disable
elan_i2c for the devices we know are not behaving properly.
