ARM: dts: armada-38x: fix NETA lockup when repeatedly switching speeds

2020-08-05T07:59:45+00:00

[ Upstream commit 09781ba0395c46b1c844f47e405e3ce7856f5989 ]

To support the change in "phy: armada-38x: fix NETA lockup when
repeatedly switching speeds" we need to update the DT with the
additional register.

ARM: dts sunxi: Relax a bit the CMA pool allocation range

2020-08-05T07:59:45+00:00

[ Upstream commit 92025b90f18d45e26b7f17d68756b1abd771b9d3 ]

The hardware codec on the A10, A10s, A13 and A20 needs buffer in the
first 256MB of RAM. This was solved by setting the CMA pool at a fixed
address in that range.

However, in recent kernels there's something else that comes in and
reserve some range that end up conflicting with our default pool
requirement, and thus makes its reservation fail.

The video codec will then use buffers from the usual default pool,
outside of the range it can access, and will fail to decode anything.

Since we're only concerned about that 256MB, we can however relax the
allocation to just specify the range that's allowed, and not try to
enforce a specific address.

ARM: dts: imx6qdl-icore: Fix OTG_ID pin and sdcard detect

2020-08-05T07:59:43+00:00

commit 4a601da92c2a782e5c022680d476104586b74994 upstream.

The current pin muxing scheme muxes GPIO_1 pad for USB_OTG_ID
because of which when card is inserted, usb otg is enumerated
and the card is never detected.

The TRM mentions GPIO_1 pad should be muxed/assigned for card detect
and ENET_RX_ER pad for USB_OTG_ID for proper operation.

This patch fixes pin muxing as per TRM and is tested on a
i.Core 1.5 MX6 DL SOM.

ARM: 8986/1: hw_breakpoint: Don't invoke overflow handler on uaccess watchpoints

2020-08-05T07:59:42+00:00

commit eec13b42d41b0f3339dcf0c4da43734427c68620 upstream.

Unprivileged memory accesses generated by the so-called "translated"
instructions (e.g. LDRT) in kernel mode can cause user watchpoints to fire
unexpectedly. In such cases, the hw_breakpoint logic will invoke the user
overflow handler which will typically raise a SIGTRAP back to the current
task. This is futile when returning back to the kernel because (a) the
signal won't have been delivered and (b) userspace can't handle the thing
anyway.

Avoid invoking the user overflow handler for watchpoints triggered by
kernel uaccess routines, and instead single-step over the faulting
instruction as we would if no overflow handler had been installed.

ARM: dts: n900: remove mmc1 card detect gpio

2020-07-29T08:18:36+00:00

[ Upstream commit ed3e98e919aaaa47e9d9f8a40c3f6f4a22577842 ]

Instead, expose the key via the input framework, as SW_MACHINE_COVER

The chip-detect GPIO is actually detecting if the cover is closed.
Technically it's possible to use the SD card with open cover. The
only downside is risk of battery falling out and user being able
to physically remove the card.

The behaviour of SD card not being available when the device is
open is unexpected and creates more problems than it solves. There
is a high chance, that more people accidentally break their rootfs
by opening the case without physically removing the card.
