cycle:
Core changes:
- Device links can optionally be added between a pin control
producer and its consumers. This will affect how the system
power management is handled: a pin controller will not suspend
before all of its consumers have been suspended. This was
necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense
to make this default in the long run. Right now it is
opt-in per driver.
- Drive strength can be specified in microamps. With decreases
in silicon technology, milliamps isn't granular enough, let's
make it possible to select drive strengths in microamps. Right
now the Meson (AMlogic) driver needs this.
New drivers:
- New subdriver for the Tegra 194 SoC.
- New subdriver for the Qualcomm SDM845.
- New subdriver for the Qualcomm SM8150.
- New subdriver for the Freescale i.MX8MN (Freescale is now a
product line of NXP).
- New subdriver for Marvell MV98DX1135.
Driver improvements:
- The Bitmain BM1880 driver now supports pin config in
addition to muxing.
- The Qualcomm drivers can now reserve some GPIOs as taken
aside and not usable for users. This is used in ACPI systems
to take out some GPIO lines used by the BIOS so that
noone else (neither kernel nor userspace) will play with them
by mistake and crash the machine.
- A slew of refurbishing around the Aspeed drivers (board
management controllers for servers) in preparation for the
new Aspeed AST2600 SoC.
- A slew of improvements over the SH PFC drivers as usual.
- Misc cleanups and fixes.

Tegra194 has PCIE L5 rst and clkreq pins which need to be controlled
dynamically at runtime. This driver supports change pinmux for these
pins. Pinmux for rest of the pins is set statically by bootloader and
will not be changed by this driver
