Subject[GIT PULL] GPIO bulk changes for the v5.4 kernel
Hi Linus,

the following is the bulk of GPIO changes for v5.4. The
main information chunk about the updates is in the signed
tag as always. This cycle has been pretty lively.

You will notice that I merged in v5.3-rc7 at a late point.
This was because the conflicts were really hairy between
the -rc:s and the bulk of development: the kind where
there is a variable rename in one branch and independent
reshuffling of code in the other. This took me some
substantial time to sort out, despite both changes being
my own. I don't know if I'm especially bad at resolving
conflicts but after failing to construct a branch for -next
several times I just sat down and resolved the conflicts
toward -rc7 once and for all. I still had to fix it up with
a patch on top.

Changes hitting Unicore and FMC in MAINTAINERS are
eplained in the signed tag as well.

Please pull it in!

Linus Walleij

The following changes since commit 089cf7f6ecb266b6a4164919a2e69bd2f938374a:

Linux 5.3-rc7 (2019-09-02 09:57:40 -0700)

are available in the Git repository at:

gpiolib: of: add a fallback for wlf,reset GPIO name (2019-09-12
10:29:17 +0100)

This is the bulk of changes in the GPIO subsystem for the
v5.4 kernel cycle.

Core changes:

- Support hierarchical GPIO irqchips. We now have three
consumers that can use this: Intel IXP4xx, ThunderX and
Qualcomm SPMI GPIO (in the pinctrl subsystem). The support
code has been long in the making and hashed out so it should
be easily adaptable for all hierarchical irqchip parents.
The code only gets compiled in if hierarchical irqchip
is used at the topmost irq controller at least, as the
hierarchical irqchip requires strict hierarchy all the
way up in the system.

- Determine the need for a "valid_mask" for GPIO lines on the
gpio_chip and conversely for the "valid_mask" for the GPIO
interrupt chip interrupt lines by looking for a
.init_valid_mask() callback in the main chip or GPIO interrupt
chip respectively. Allocate it with bitmap_alloc().

- Isolate the device tree/open firmware GPIO description code
out in its own file properly.

- Isolate the ACPI GPIO description code out in its own file

- Drop a whole lot of #ifdef:s in the main includes: it does
not hurt to keep the include items around, and we get
quicker and clearer compile failures if the appropriate
kernel symbols are not selected for drivers.

New/deleted drivers:

- New driver for Aspeed SGPIO.

- The KS8695 driver is deleted as the platform gets deleted
from arch/arm in this kernel cycle.

- The Cirrus Logic Madera driver now supports CS47L92 and

- The Freescale MPC8xxx now supports LS1028A and LS1088A.

Driver improvements:

- We pass the GPIO irqchip intialization by directly filling
in the struct instead of using set-up functions (the new
way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed,
ZX, VF610, TQMX86, MT7621, Zynq and EP93xx.

Out-of-band changes:

- Fix a GPIO header inclusion in Unicore - no response from

- Drop FMC subsystem from MAINTAINERS - was deleted in the
GPIO tree last cycle so let's mop up the shards.
