The name .dev in a struct is normally reserved for a struct device
that is let us say a superclass to the thing described by the struct.
struct gpio_chip stands out by confusingly using a struct device *dev
to point to the parent device (such as a platform_device) that
represents the hardware. As we want to give gpio_chip:s real devices,
this is not working. We need to rename this member to parent.
This was done by two coccinelle scripts, I guess it is possible to
combine them into one, but I don't know such stuff. They look like
this:
@@
struct gpio_chip *var;
@@
-var->dev
+var->parent
and:
@@
struct gpio_chip var;
@@
-var.dev
+var.parent
and:
@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parent
Plus a few instances of bgpio that I couldn't figure out how
to teach Coccinelle to rewrite.
This patch hits all over the place, but I *strongly* prefer this
solution to any piecemal approaches that just exercise patch
mechanics all over the place. It mainly hits drivers/gpio and
drivers/pinctrl which is my own backyard anyway.

The RK817 & RK809 chip is a power management IC for multimedia and handheld
devices. It contains the following components:
- Regulators
- RTC
- Clkout
- Pinctrl
- Powerkey
The RK817 & RK809 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.
The following is the different between the RK817 and the RK809.
1、The dcdc-buck5 is a boost dcdc for RK817 and is a buck for RK809.
2、The RK817 have one switch but The Rk809 have two.
3、The RK817 have a charger and powerpatch function but RK809 not.

commit 85e9b13cbb upstream.
Fix child-node lookup during probe, which ended up searching the whole
device tree depth-first starting at the parent rather than just matching
on its children.
To make things worse, the parent node was prematurely freed, while the
child node was leaked.
Note that the CONFIG_OF compile guard can be removed as
of_get_child_by_name() provides a !CONFIG_OF implementation which always
fails.

commit 0a423772de upstream.
A helper purported to look up a child node based on its name was using
the wrong of-helper and ended up prematurely freeing the parent of-node
while leaking any matching node.
To make things worse, any matching node would not even necessarily be a
child node as the whole device tree was searched depth-first starting at
the parent.

commit 15d8374874 upstream.
On the Tegra124 Nyan-Big chromebook the very first SPI message sent to
the EC is failing.
The Tegra SPI driver configures the SPI chip-selects to be active-high
by default (and always has for many years). The EC SPI requires an
active-low chip-select and so the Tegra chip-select is reconfigured to
be active-low when the EC SPI driver calls spi_setup(). The problem is
that if the first SPI message to the EC is sent too soon after
reconfiguring the SPI chip-select, it fails.
The EC SPI driver prevents back-to-back SPI messages being sent too
soon by keeping track of the time the last transfer was sent via the
variable 'last_transfer_ns'. To prevent the very first transfer being
sent too soon, initialise the 'last_transfer_ns' variable after calling
spi_setup() and before sending the first SPI message.

For PMIC that power off supplies by write register via i2c bus,
it's better to do power off at syscore shutdown.
Because when run to kernel's "pm_power_off" call, i2c may has
been stopped or PMIC may not be able to get i2c transfer while
there are too many devices are competiting.
This patch effects on PMIC: RK808/RK818/RK816, not including RK805
which power off system by pull up pmic sleep pin in ATF.

RK618 is a partner chip for Rockchip mobile application processor.
RK618 includes two RGB display input interface with double data rate.
With the internal MUX function, it can output 1080P HDMI signal to
TV and output RGB/LVDS/MIPI signal to TFT panel. In this case, RK618
can support dual panel (TV and TFT) display.
RK618 includes a audio codec, which with two I2S/PCM interface, two

[ Upstream commit 7e9c40c639 ]
In the current boot, clients making use of the AB8500 sysctrl
may be probed before the ab8500-sysctrl driver. This gives them
-EINVAL, but should rather give -EPROBE_DEFER.
Before this, the abx500 clock driver didn't probe properly,
and as a result the codec driver in turn using the clocks did
not probe properly. After this patch, everything probes
properly.
Also add OF compatible-string probing. This driver is all
device tree, so let's just make a drive-by-fix of that as
well.

FUSB302 default cc status is UFP. If we reset the UFP system,
the UFP PD status would be reset, but the DPF can't detecte
the disconnection since cc status did not changed. Reset UFP
would send hardreset to DPF due to wait power caps timeout.
And that would cause the power reset.
So, let's use softreset instead of hardreset in this case.

Commit 16fa3dc75c ("mfd: omap-usb-tll: HOST TLL platform driver")
added support for USB TLL, but uses OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF
bit the wrong way. The comments in the code are correct, but the inverted
use of OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF causes the register to be
enabled instead of disabled unlike what the comments say.

If a partner port sends a packet at approximately the same time as we
send a packet, we may end up with the initial packet followed by the
GOOD_CRC reply in our HW FIFO. Don't automatically discard the first
packet in the FIFO. Instead, discard the packet only if it's a GOOD_CRC
packet. And, modify our get_message function to automatically discard
GOOD_CRC in search of a meaningful packet.
In addition, due to interrupt latency, we can't rely on receiving one
interrupt per incoming packet. If our Rx FIFO is non-empty, assume that
it contains at least one packet.

tcpm_get_message(); //get the data and close to 30ms

auto_vdm_machine
