e1c97949ee gpio: allow passing NULL to gpio_request_by_line_name() to search all gpio controllers
The API is more convenient to use if one doesn't have to know upfront
which gpio controller has a line with the name one is searching for,
and arrange to look that device up somehow. Or implement this loop
oneself.

39409fac2c fs: ext4: fix files seen as symlink during deletion
The deletion process handles special case for symlinks whose target are
small enough that it fits in struct ext2_inode.b.symlink. So no block had
been allocated. But the check of file type wrongly considered regular
files as symlink. So, no block was freed. So, the EXT4 partition could be
corrupted because of no free block available.

59b1c9be01 cmd: pci: Add command to set MPS of all PCIe devices
Enable tuning of the PCI Express MPS (Maximum Payload Size) of
each device. The Maximum Read Request Size is not altered.

The SAFE method uses the largest MPS value supported by all devices in the
system for each device. This method is the same algorithm as used by Linux
pci=pcie_bus_safe.

The PEER2PEER method sets all devices to the minimal (128 byte) MPS, which
allows hot plug of devices later that might only support the minimum size,
and ensures compatibility of DMA between two devices on the bus.

19213d7a65 sysinfo: gpio: fix loop over DT "revisions" array
There can certainly be a lot more elements in the "revisions" (and
"names") arrays than there are gpios used to form the trinary number
we're searching for; we simply don't know the array size up-front.

Nor do we need to, because the loop body already knows to recognize
-EOVERFLOW as "not that many elements present" (and we have a test
that specifically ensures that dev_read_u32_index() returns exactly
that). So just drop the i < priv->gpio_num condition.

While in here, fix the weird placement of the default: keyword.

2360409d9c arm: mvebu: Remove A38x BOOT_FROM_UART_ALT 0x3f constant
A385 BootROM treats strapping configuration 0x3f as invalid. When booting
fails (e.g. because of invalid configuration) then BootROM fallbacks to
UART booting.

Detecting BootROM fallback to UART booting is implemented in U-Boot since
commit 2fd4284051 ("ARM: mach-mvebu: handle fall-back to UART boot").

So there is no need to define BOOT_FROM_UART_ALT constant and special
handling for it anymore, remove it.

This change effectively revers commit f3a88e2ca1 ("arm: mvebu: fix boot
from UART on ClearFog Base").

352ed65df7 iot2050: Add support for configuring M.2 connector
The M.2 slots of the related IOT2050 variant need to be configured
according to the plugged cards. This tries to detect the card using the
M.2 configuration pins of the B-key slot. If that fails, a U-Boot
environment variable can be set to configure manually. This variable is
write-permitted also in secure boot mode as it is not able to undermine
the integrity of the booted system.

The configuration is then applied to mux the serdes and to fix up the
device tree passed to or loaded by the bootloader. The fix-ups are
coming from device tree overlays that are embedded into the firmware
image and there also integrity protected. The OS remains free to load
a device tree to which they do not apply: U-Boot will not fail to boot
in that case.

Based on original patch by Chao Zeng.
