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.

Say yes here to enable the Broadcom iProc GPIO driver.

The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use
|
|
same GPIO Controller IP hence this driver could be used for all.
|
|
|
|
The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU
|
|
GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and
|
|
the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are
|
|
supported by this driver.
|
|
|
|
The Broadcom NSP has two GPIO controllers including the ChipcommonA
|
|
GPIO, the ChipcommonB GPIO. Later controller is supported by this
|
|
driver.
|
|
|
|
The Broadcom NS2 has two GPIO controller including the CRMU GPIO,
|
|
the ChipcommonG GPIO. Both controllers are supported by this driver.
|
|
|
|
The Broadcom Stingray GPIO controllers are supported by this driver.
|
|
|
|
All above SoCs GPIO controllers support basic PINCONF functions such
|
|
as bias pull up, pull down, and drive strength configurations, when
|
|
these pins are muxed to GPIO.
|
|
|
|
It provides the framework where pins from the individual GPIO can be
|
|
individually muxed to GPIO function, through interaction with the
|
|
SoCs IOMUX controller. This features could be used only on SoCs which
|
|
support individual pin muxing.
