It can also wake the board from sleep. This functionality was

....
260: 100001 0 gpio-mxc 31 Level mma8451
The MMA8451 interrupt triggers as low level, so the GPIO6_IO31 pin
needs to activate its pull up, otherwise it will stay always at low level
generating multiple interrupts.
The current device tree does not configure the IOMUX for this pin, so
it uses whathever comes configured from the bootloader.
The IOMUXC_SW_PAD_CTL_PAD_EIM_BCLK register value comes as 0x8000 from
the bootloader, which has PKE bit cleared, hence disabling the
pull-up.
Instead of relying on a previous configuration from the bootloader,
configure the GPIO6_IO31 pin with pull-up enabled in order to fix
this problem.

bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available

GPIO on CM3 in mainline yet, so this node was left incomplete without
the actual GPIO definition. Since commit 025bf37725 ("gpio: Fix return
value mismatch of function gpiod_get_from_of_node()") this causing probe
issues of the leds-gpio driver for users of the CM3 dtsi file.

Commit 572cf7d7b0 ("ARM: dts: Improve omap l4per idling with wlcore edge
sensitive interrupt") changed wlcore interrupts to use edge interrupt based
on what's specified in the wl1835mod.pdf data sheet.
However, there are still cases where we can have lost interrupts as
described in omap_gpio_unidle(). And using a level interrupt instead of edge
interrupt helps as we avoid the check for untriggered GPIO interrupts in
omap_gpio_unidle().
And with commit e6818d29ea ("gpio: gpio-omap: configure edge detection
for level IRQs for idle wakeup") GPIOs idle just fine with level interrupts.
Let's change omap4 and 5 wlcore users back to using level interrupt
instead of edge interrupt. Let's not change the others as I've only seen
this on omap4 and 5, probably because the other SoCs don't have l4per idle
independent of the CPUs.

The clkctrl code searches for the parent clockdomain based on the name
of the CM provider node. The introduction of SGX node for omap5 made
the node name for the gpu_cm to be clock-controller. There is no
clockdomain named like this, so the lookup fails. Fix by changing
the node name properly.

Fixes for omaps for v5.4-rc cycle
Here are fixes for omaps to deal with few regressions, and to fix
more boot time errors and warnings:
- The recent ti-sysc interconnect target module driver changes had
incorrect clock bits for both clocks and dts that cause warnings
- For omap3-gta04, gpio changes caused the LCD to break a while back,
and after discussing things the right fix is to set spi-cs-high
- Recent omapdrm changes to use generic panels caused tfp410 to be
disabled as we now must enable the generic support for it in
defconfig
- Recent omapdrm and backlight changes also finally made droid4 LCD
to work, so let's enable it in the defconfig it can be used out
of the box. This is not strictly a fix, but we still also have the
older CONFIG_MFD_TI_LMU options available so this cuts down the
confusion for trying to guess which display and which backlight
is needed
- Recent ti-sysc interconnect target module changes need the gpio
module disabled on some boards, but this now needs to happen at
the module level, not at the gpio driver level
- Recent changes to probe system timers with ti-sysc caused warnings
about mismatch in syconfig registers, so let's configure the option
for RESET_STATUS as available in the TRMs
- Recent changes to probe LCDC with ti-sysc caused warnings about
mismatch in sysconfig registers, so let's configure the missing
idlemodes for both platform data and dts as documented in TRMs
- Since we moved mach-omap2 to probe with device tree, we've been
getting voltage controller warnings. Turns out this code is no
longer needed, so let's just remove omap2_set_init_voltage() to
get rid of the pointless warnings
- Configure am4372 dispc memory bandwidth to avoid underflow errors

TRM "Table 13-34. SYSCONFIG Register Field Descriptions" lists both
standbymode and idlemode that should be just the sidle and midle
registers where midle is currently unconfigured for lcdc_sysc. As
the dts data has been generated based on lcdc_sysc, we now have an
empty "ti,sysc-midle" property.
And so we currently get a warning for lcdc because of a difference
with dts provided configuration compared to the legacy platform
data. This is because lcdc has SYSC_HAS_MIDLEMODE configured in
the platform data without configuring the modes.
Let's fix the issue by adding the missing midlemode to lcdc_sysc,
and configuring the "ti,sysc-midle" property based on the TRM
values.

commit 6953c57ab1 "gpio: of: Handle SPI chipselect legacy bindings"
did introduce logic to centrally handle the legacy spi-cs-high property
in combination with cs-gpios. This assumes that the polarity
of the CS has to be inverted if spi-cs-high is missing, even
and especially if non-legacy GPIO_ACTIVE_HIGH is specified.
The DTS for the GTA04 was orginally introduced under the assumption
that there is no need for spi-cs-high if the gpio is defined with
proper polarity GPIO_ACTIVE_HIGH.
This was not a problem until gpiolib changed the interpretation of
GPIO_ACTIVE_HIGH and missing spi-cs-high.
The effect is that the missing spi-cs-high is now interpreted as CS being
low (despite GPIO_ACTIVE_HIGH) which turns off the SPI interface when the
panel is to be programmed by the panel driver.
Therefore, we have to add the redundant and legacy spi-cs-high property
to properly activate CS.

complex inter-depondencies. The fact that there are these
interdependencies tends to meant that these are often actually the
most interesting new additions:
- The new Aspeed AST2600 baseboard management controller is added,
this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
had some dependencies on other device drivers.
- After many years, support for the MMP2 based OLPC XO-1.75 finally
makes it into the kernel.
- The Armada 3720 based Turris Mox open source router platform is a
late addition and it follows some preparatory work across multiple
branches.
- The OMAP2+ platform had some large-scale cleanup involving driver

Pull ARM DT updates from Arnd Bergmann:
"This is another huge branch with close to 450 changessets related to
devicetree files, roughly half of this for 32-bit and 64-bit
respectively. There are lots of cleanups and additional hardware
support for platforms we already support based on SoCs from Renesas,
ST-Microelectronics, Intel/Altera, Rockchips, Allwinner, Broadcom and
other manufacturers.
A total of 6 new SoCs and 37 new boards gets added this time, one more
SoC will come in a follow-up branch. Most of the new boards are for
64-bit ARM SoCs, the others are typically for the 32-bit Cortex-A7.
Going more into details for SoC platforms with new hardware support:
- The Snapdragon 855 (SM8150) is Qualcomm's current high-end phone
platform, usually paired with an external 5G modem. So far we only
support the Qualcomm SM8150 MTP reference platform, but no actual
products.
- For the slightly older Qualcomm platforms, support for several
interesting products is getting added: Three laptops based on
Snapdragon 835/MSM8998 (Asus NovaGo, HP Envy X2 and Lenovo Miix
630), one laptop based on Snapdragon 850/sdm850 (Lenovo Yoga C630)
and several phones based on the older Snapdragon 410/MSM8916
(Samsung A3 and A5, Longcheer L8150 aka Android One 2nd gen "seed"
aka Wileyfox Swift).
- Mediatek MT7629 is a new wireless network router chip, similar to
the older MT7623. It gets added together with the reference board
implementation.
- Allwinner V3 is a repackaged version of the existing low-end V3s
chip, and is used in the tiny Lichee Pi Zero plus, also added here.
There is also a new TV set-top box based on Allwinner H6, the Tanix
TX6, and the eMMC variant of the Olimex A64-Olinuxino development
board.
- NXP i.MX8M Nano is a new member of the ever-expanding i.MX SoC
family, similar to the i.MX8M Mini. As usual, there is a large
number of new boards for i.MX SoCs: Einfochips i.MX8QXP AI_ML,
SolidRun Hummingboard Pulse baseboard and System-on-Module,
Boundary Devices i.MX8MQ Nitrogen8M, and TechNexion
PICO-PI-IMX8M-DEV for the 64-bit i.MX8 line. For 32-bit, we get the
Kontron i.MX6UL N6310 SoM with two baseboards, the PHYTEC
phyBOARD-Segin SoM with three baseboards, and the Zodiac Inflight
Innovations i.MX7 RMU2 board.
- In a different NXP product line, the Layerscape LS1046A "Freeway"
reference board gets added.
- Amlogic SM1 (S905X3) and G12B (S922X, A311D) are updated chips from
their set-top-box line and smart speaker with newer CPU and GPU
cores compared to their predecessors. Both are now also supported
by the Khadas VIM3 development board series, and the dts files for
that get reorganized a bit to better deal with all variants.
Another board based on SM1 that gets added is the SEI Robotics
SEI610.
- There are a handful of new x86 and Power9 server boards using
Aspeed BMC chips that are gaining support for running Linux on the
BMC through the OpenBMC project: Facebook
Minipack/Wedge100/Wedge40, Lenovo Hr855xg2, and Mihawk. Notably
these are still new machines using SoCs based on the ARM9 and ARM11
CPU cores, as support for the new Cortex-A7 based AST2600 is still
ramping up.
- There are three new end-user products using 32-bit Rockchips SoCs:
Mecer Xtreme Mini S6 is an Android "mini PC" box based on the
low-end RK3229 chip, while the two AOpen products Chromebox Mini
(Fievel) and Chromebase Mini (Tiger) run ChromeOS and are meant for
commercial settings(digital signage, PoS, ...).
- One more single-board computer based on the popular 64-bit RK3399
is added: the Leez RK3399 P710"

The D-Link DIR-685 had its clock polarity set as active
low using the special SPI "spi-cpol" property.
This is not correct: the datasheet clearly states:
"Fix SCL to GND level when not in use" which is
indicative that this line is active high.
After a recent fix making the GPIO-based SPI driver
force the clock line de-asserted at the beginning of
each SPI transaction this reared its ugly head: now
de-asserted was taken to mean the line should be
driven high, but it should be driven low.
Fix this up in the DTS file and the display works again.
