123dfdbcfa phy-sun4i-usb: Add support for the usb-phys on the sun8i-a23 SoC
The usb-phys on the sun8i-a23 SoC have the same setup wrt clocks as on the
sun6i-a31 SoC, but there are only 2 instead of 3 like on the sun5i-a13 SoC.

d2332303ef phy-sun4i-usb: Add id and vbus detection support for the otg phy (phy0)
The usb0 phy is connected to an OTG controller, and as such needs some special
handling:

1) It allows explicit control over the pullups, enable these on phy_init and
disable them on phy_exit.

2) It has bits to signal id and vbus detect to the musb-core, add support for
for monitoring id and vbus detect gpio-s for use in dual role mode, and set
these bits to the correct values for operating in host only mode when no
gpios are specified in the devicetree.

While updating the devicetree binding documentation also add documentation
for the sofar undocumented usage of regulators for vbus for all 3 phys.

05a051436b ARM: at91/dt: add a new DT property to support FIFOs on Atmel USARTs
This patch adds a new DT property, "atmel,fifo-size", to enable and set
the maximum number of data the RX and TX FIFOs can store on FIFO capable
USARTs.

Please be aware that the VERSION register can not be used to guess the
size of FIFOs. Indeed, for a given hardware version, the USARTs can be
integrated on Atmel SoCs with different FIFO sizes. Also the
"atmel,fifo-size" property is optional as older USARTs don't embed FIFO at
all.

Besides, the FIFO size can not be read or guessed from other registers:
When designing the FIFO feature, no dedicated registers were added to
store this size. Unsed spaces in the I/O register range are limited and
better reserved for future usages. Instead, the FIFO size of each
peripheral is documented in the programmer datasheet.

Finally, on a given SoC, there can be several instances of USART with
different FIFO sizes. This explain why we'd rather use a dedicated DT
property than use the "compatible" property.

Due to Advisory 21 as documented in AM437x errata document,
UART module cannot be disabled once DMA is used. The only
workaround is to softreset the module before disabling it.

DRA7x UARTs are compatible to AM437x UARTs in terms of
this errata and prescribed workaround.

Enable usage of workaround for this errata on DRA7x SoCs.

4fcdff9bca serial: 8250_omap: introduce "ti,am3352-uart" compatible property
Use of of_machine_is_compatible() for handling AM335x specific
"DMA kick" quirk in 8250_omap driver makes it ugly to extend the
quirk for other platforms. Instead use a new compatible.

The new compatible will also make it easier to take care of
other quirks on AM335x and like SoCs.

In order to not break backward DTB compatibility for users of
8250_omap driver on AM335x based boards, existing use of
of_machine_is_compatible() has not been removed.

f78f5b90c4 rcu: Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN()
This commit renames rcu_lockdep_assert() to RCU_LOCKDEP_WARN() for
consistency with the WARN() series of macros.  This also requires
inverting the sense of the conditional, which this commit also does.

36bd168355 ARM: dts: Add phyBOARD-WEGA-AM335x rdk
phyBOARD-WEGA-AM335x represents a direct soldered
combination of a phyCORE-AM335x SoM and carrier board.

Different kind of SoM options can be connected to
the wega carrier board. So we created a separate
wega dtsi file. The final dts contains the actual
SoM on the carrier board.

WEGA carrier board features:
* ETH phy on carrier board: 1x MII
* 1x CAN
* 2x UART
* USB0 (device)
* USB1 (host)
* mSD slot

5e9972cd6f iio: adc: vf610: Determine sampling frequencies by using minimum sample time
The driver currently does not take into account the minimum sample time
as per the Figure 6-8 Chapter 9.1.1 12-bit ADC electrical characteristics.
We set a static amount of cycles instead of considering the sample time
as a given value, which depends on hardware characteristics.

Determine sampling frequencies by first reading the device tree property
node and then calculating the required Long Sample Time Adder (LSTAdder)
value, based on the ADC clock frequency and sample time value obtained
from the device tree. This LSTAdder value is then used for calculating
the sampling frequencies possible.

In case the sample time property is not specified through the device
tree, a safe default value of 1000ns is assumed.

1ae25d626c power: reset: at91: add sama5d3 reset function
This patch introduces a new compatible string: "atmel,sama5d3-rstc" and
new reset function for sama5d3 and later chips.

As in sama5d3 or later chips, we don't have to shutdown the DDR
controller before reset. Shutdown the DDR controller before reset is a
workaround to avoid DDR signal driving the bus, but since sama5d3 and
later chips there is no such a conflict.

So in this patch:
   1. the sama5d3 reset function only need to write the rstc register
and return.
   2. we can remove the code related with sama5d3 DDR controller as
we don't use it at all.
