      max77686 pmic is supporting with max77686.c under pmic/ and regulator/
direnctroy. Remove pmic_max77686.c what didn't use anywhere.
Instead, enable CONFIG_DM_REGULATOR_MAX77686 and
CONFIG_DM_PMIC_MAX77686.

      arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A · acf15001
      由 Lokesh Vutla 提交于 
      Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

      syscon: add Linux-compatible syscon API · e151a1c2
      由 Masahiro Yamada 提交于 
      The syscon implementation in U-Boot is different from that in Linux.
Thus, DT files imported from Linux do not work for U-Boot.

In U-Boot driver model, each node is bound to a dedicated driver
that is the most compatible to it.  This design gets along with the
concept of DT, and the syscon in Linux originally worked like that.

However, Linux commit bdb0066df96e ("mfd: syscon: Decouple syscon
interface from platform devices") changed the behavior because it is
useful to let a device bind to another driver, but still work as a
syscon provider.

That change had happened before U-Boot initially supported the syscon
driver by commit 6f98b750 ("dm: Add support for generic system
controllers (syscon)").  So, the U-Boot's syscon works differently
from the beginning.  I'd say this is mis-implementation given that
DT is not oriented to a particular project, but Linux is the canon
of DT in practice.

The problem typically arises in the combination of "syscon" and
"simple-mfd" compatibles.

In Linux, they are orthogonal, i.e., the order between "syscon" and
"simple-mfd" does not matter at all.

Assume the following compatible.

   compatible = "foo,bar-syscon", "syscon", "simple-mfd";

In U-Boot, this device node is bound to the syscon driver
(driver/core/syscon-uclass.c) since the "syscon" is found to be the
most compatible.  Then, syscon_get_regmap() succeeds.

However,

   compatible = "foo,bar-syscon", "simple-mfd", "syscon";

does not work because this node is bound to the simple-bus driver
(drivers/core/simple-bus.c) in favor of "simple-mfd" compatible.
The compatible string "syscon" is just dismissed.

Moreover,

   compatible = "foo,bar-syscon", "syscon";

works like the first case because the syscon driver populates the
child devices.  This is wrong because populating children is the job
of "simple-mfd" (or "simple-bus").

This commit ports syscon_node_to_regmap() from Linux.  This API
does not require the given node to be bound to a driver in any way.

      regmap: change regmap_init_mem() to take ofnode instead udevice · d3581236
      由 Masahiro Yamada 提交于 
      Currently, regmap_init_mem() takes a udevice. This requires the node
has already been associated with a device. It prevents syscon/regmap
from behaving like those in Linux.

Change the first argumenet to take a device node.

      regmap: clean up regmap allocation · 8c1de5e0
      由 Masahiro Yamada 提交于 
      Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members.  There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".

As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.

Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

      SPDX: Convert all of our multiple license tags to Linux Kernel style · 4549e789
      由 Tom Rini 提交于 
      When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document.  Note that parenthesis are
allowed so when they were used before we continue to use them.

This commit changes all instances where we have a single declared

contents.  There's also a few places where I found we did not have a tag
and have introduced one.

      serial: serial_stm32: Enable overrun · 7b3b74d3
      由 Patrice Chotard 提交于 
      Enable uart overrun feature which allows to benefits of uart
FIFO usage.

Previously overrun management was disabled, this has to effect
to bypassed the uart FIFO usage even if FIFO was enabled.
In particular configuration, for example when video console is
enabled, copy/pasting a long command line in console results in
corruption. This is due to the fact that a lot of time is consumed
in flushing the cache during frame buffer update, so uart chars are
not read fast enough.

By using uart FIFO and managing overrun, long command line can by
copy/paste in console without being corrupted.
