ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7

2018-01-31T13:46:12+00:00

commit 56aeb07c914a616ab84357d34f8414a69b140cdf upstream.

MPP7 is currently muxed as "gpio", but this function doesn't exist for
MPP7, only "gpo" is available. This causes the following error:

kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7
pinctrl core: failed to register map default (6): invalid type given
kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22
kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22
kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver
kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22

So the pinctrl driver is not probed, all device drivers (including the
UART driver) do a -EPROBE_DEFER, and therefore the system doesn't
really boot (well, it boots, but with no UART, and no devices that
require pin-muxing).

Back when the Device Tree file for this board was introduced, the
definition was already wrong. The pinctrl driver also always described
as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11,
a hog pin failing to be muxed was turned from a simple warning to a
hard error that caused the entire pinctrl driver probe to bail
out. This is probably the result of commit 6118714275f0a ("pinctrl:
core: Fix pinctrl_register_and_init() with pinctrl_enable()").

This commit fixes the Device Tree to use the proper "gpo" function for
MPP7, which fixes the boot of OpenBlocks A7, which was broken since
Linux 4.11.

ARM: dts: am335x-evmsk: adjust mmc2 param to allow suspend

2017-12-25T13:20:08+00:00

[ Upstream commit 9bcf53f34a2c1cebc45cc12e273dcd5f51fbc099 ]

mmc2 used for wl12xx was missing the keep-power-in suspend
parameter. As a result the board couldn't reach suspend state.

Revert "ARM: dts: imx53-qsb-common: fix FEC pinmux config"

2017-11-18T10:06:30+00:00

This reverts commit 2eb85ef18c6570e8a59643cd8d5a66122461b1fc which is
commit 8b649e426336d7d4800ff9c82858328f4215ba01 upstream.

Turns out not to be a good idea in the stable kernels for now as Patrick
writes:
	As discussed for 4.4 stable queue this patch might break
	existing machines, if they use a different pinmux configuration
	with their own bootloader.

ARM: dts: imx53-qsb-common: fix FEC pinmux config

2017-11-15T09:04:11+00:00

[ Upstream commit 8b649e426336d7d4800ff9c82858328f4215ba01 ]

The pinmux configuration in device tree was different from manual
muxing in /board/freescale/mx53loco/mx53loco.c
All pins were configured as NO_PAD_CTL(1 << 31), which was fine as the
bootloader already did the correct pinmuxing for us.
But recently u-boot is migrating to reuse device tree files from the
kernel tree, so it seems to be better to have the correct pinmuxing in
our files, too.

ARM: dts: n900: Mark eMMC slot with no-sdio and no-sd flags

2017-08-11T16:30:12+00:00

[ Upstream commit 4cf48f1d7520a4d325af58eded4d8090e1b40be7 ]

Trying to initialize eMMC slot as SDIO or SD cause failure in n900 port of
qemu. eMMC itself is not detected and is not working.

Real Nokia N900 harware does not have this problem. As eMMC is really not
SDIO or SD based such change is harmless and will fix support for qemu.

GIC_PPI flags were misconfigured for the timers, resulting in errors
like:
[    0.000000] GIC: PPI11 is secure or misconfigured

Changing them to being edge triggered corrects the issue

ARM: kirkwood: ib62x0: fix size of u-boot environment partition

Commit 148c274ea644 ("ARM: kirkwood: ib62x0: add u-boot environment
partition") split the "u-boot" partition into "u-boot" and "u-boot
environment".  However, instead of the size of the environment, an offset
was given, resulting in overlapping partitions.
