drm/panel: Add support for Armadeus ST0700 Adapt

2019-09-16T06:22:21+00:00

[ Upstream commit c479450f61c7f1f248c9a54aedacd2a6ca521ff8 ]

This patch adds support for the Armadeus ST0700 Adapt. It comes with a
Santek ST0700I5Y-RBSLW 7.0" WVGA (800x480) TFT and an adapter board so
that it can be connected on the TFT header of Armadeus Dev boards.

iio: adc: exynos-adc: Use proper number of channels for Exynos4x12

2019-09-16T06:22:06+00:00

[ Upstream commit 103cda6a3b8d2c10d5f8cd7abad118e9db8f4776 ]

Exynos4212 and Exynos4412 have only four ADC channels so using
"samsung,exynos-adc-v1" compatible (for eight channels ADCv1) on them is
wrong.  Add a new compatible for Exynos4x12.

commit 80785f5a22e9073e2ded5958feb7f220e066d17b upstream.

Armada 8040 needs four clocks to be enabled for MDIO accesses to work.
Update the binding to allow the extra clock to be specified.

can: hi311x: Use level-triggered interrupt

2018-12-01T08:37:30+00:00

commit f164d0204b1156a7e0d8d1622c1a8d25752befec upstream.

If the hi3110 shares the SPI bus with another traffic-intensive device
and packets are received in high volume (by a separate machine sending
with "cangen -g 0 -i -x"), reception stops after a few minutes and the
counter in /proc/interrupts stops incrementing.  Bus state is "active".
Bringing the interface down and back up reconvenes the reception.  The
issue is not observed when the hi3110 is the sole device on the SPI bus.

Using a level-triggered interrupt makes the issue go away and lets the
hi3110 successfully receive 2 GByte over the course of 5 days while a
ks8851 Ethernet chip on the same SPI bus handles 6 GByte of traffic.

Unfortunately the hi3110 datasheet is mum on the trigger type.  The pin
description on page 3 only specifies the polarity (active high):
