In spite of the summary line, U-Boot commits [1-2] seem to have
aligned the U-Boot PFC tables to Linux v5.1 rather than to v5.0, since
they also imported the Linux 5.1 commits listed in [3].
What current commit tries to accomplish is to align the Gen2 and Gen3
pinctrl tables to Linux v5.2. Importing these updates in two steps
as done before (i.e. separately for Gen2 and Gen3) is somewhat difficult
due to Linux commits like [5-6] which atomically update both Gen2/3
platforms and whose breakdown would not be easily possible.
The detailed list of Linux commits squashed into this U-Boot patch is
shown in [4]. The second column in [4] depicts the patch id mismatch
between the original Linux and the resulted U-Boot commit. The
exclamation mark means that manual conflict resolution was involved
during cherry picking Linux commit into U-Boot repository (this is
mainly caused by dropped changes in files like pfc-r8a7795-es1.c and
pfc-r8a77980.c which are missing in U-Boot).
This patch has been applied on top of v2019.07-rc4-155-g8754656680b6 and
boot-tested on:

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 a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Add PFC pincontrol driver for the Renesas RCar Gen3 R8A7795 and R8A7796
SoCs. This driver uses the PFC pin tables from Linux, thus letting us
share the occassional fixes to those tables. This driver also has a DT
support, so the pinmux is configured from DT instead of the ad-hoc setup
in board file.
This driver is meant to replace the pinmux part of SH_GPIO_PFC driver.
