622597dee4 i2c: designware: add reset ctrl to driver
Add code to look for a reset manager property. Specifically, look for the
reset-names of 'i2c'. A reset property is an optional feature, so only print
out a warning and do not fail if a reset property is not present.

If a reset property is discovered, then use it to deassert, thus bringing the
IP out of reset.

introduce a configuration CONFIG_FEC_MXC_MDIO_BASE to indicate

In Kconfig, user needs enable CONFIG_FEC_MXC_SHARE_MDIO first to enter
the CONFIG_FEC_MXC_MDIO_BASE.

When using ethernet DM driver, the recv interface has a
change with non-DM interface, that driver needs to set
the packet pointer and provide it to upper layer to process.

In fec driver, the fecmxc_recv functions does not handle the
packet pointer parameter. This may cause crash in upper layer
processing because the packet pointer is not set.

This patch allocates a buffer for the packet pointer and free it
through free_pkt interface.

ea5512eb09 spi: sh_qspi: Make use of the 32byte FIFO
The QSPI controller on RCar Gen2 has 32byte FIFO. Instead of doing
the SPI transmission 1 byte at time, if there is a 32byte chunk of
data to be transferred, fill the FIFO completely and then transfer
the data to/from the FIFO. This increases the SPI NOR access speed
significantly.

db1266d696 mmc: uniphier: Add support for 16bit variant
Add support for 16bit mutation of the Matsushita SD IP. Since some
registers are internally 32bit, the matsu_sd_{read,write}l() has
to special-case this 16bit variant a bit.

a9d7990dc4 serial: Fix Makefile during SPL and TPL build
This patch fixes a situation where CONFIG_DM_SERIAL is enabled for
regular U-Boot and SPL, but not for TPL. In that case, the build
will try to include serial-uclass into the TPL nonetheless, because
CONFIG_DM_SERIAL is set.

The solution is to check if the build is for SPL or TPL and in that
case, check if CONFIG_$(SPL_TPL_)DM_SERIAL is also set. Only in that
case, include serial-uclass.c . If the build is for regular U-Boot,
CONFIG_BUILD is not set, so only check if CONFIG_DM_SERIAL is set
and if so, include serial-uclass.c

02325c7bfd treewide: fix up files incorrectly marked executable
Inspired by the following kernel commit:

"commit 90fda63fa1156ec1bcfd7f9ca384cec221f70a21
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Sat Apr 7 13:31:23 2018 -0700

treewide: fix up files incorrectly marked executable

Joe Perches noted that we have a few source files that for some
inexplicable reason (read: I'm too lazy to even go look at the history)
are marked executable:

drivers/gpu/drm/amd/amdgpu/vce_v4_0.c
drivers/net/ethernet/cadence/macb_ptp.c

A simple git command line to show executable C/asm/header files is this:

   git ls-files -s '*.[chsS]' | grep '^100755'

and then you can fix them up with scripting by just feeding that output
into:

  | cut -f2 | xargs chmod -x

and commit it.

Which is exactly what this commit does.

8ae1f82988 mmc: use core clock frequency in bcm2835 sdhost
In raspberrypi-firmware 7fdcd00e00a42a1c91e8bd6f5eb8352fe9358557 and
later start.elf now sets the EMMC clock to 200 MHz.

According to Phil Elwell in
https://github.com/raspberrypi/firmware/issues/953
the SDHost controller shares the core/VPU clock and doesn't use
the EMMC clock.

Use the core clock id when determining the frequency to allow
U-Boot to work with recent versions of raspberrypi-firmware.
Otherwise U-Boot hangs at:

The original DT binding used by U-Boot's sun8i-emac driver was not really

12afd95711 net: sun8i-emac: add support for new EMAC DT binding
The Ethernet MAC used in newer Allwinner SoCs (H3, A64, H5) got an
upstream Linux driver in v4.15.
This one uses a slightly different binding from the original one used
by the U-Boot driver.
The differences to the old binding are:
- The "syscon" address is held in a separate node, referenced via a
  phandle in the "syscon" property.
- The reference to the PHY is held in a property called "phy-handle",
  not "phy".
- The PHY register is at offset 0x30 in the syscon device, not at 0.
- The internal PHY is activated when the node, which phy-handle points
  to, is a child node of an "allwinner,sun8i-h3-mdio-internal" node.

Teach the U-Boot driver how to find its resources in a "new-style" DT,
so that we can use a Linux kernel compatible DT for U-Boot as well.
This keeps support for the old binding for now, to allow a smooth
transition.

spl: nand: sunxi: use PIO instead of DMA
SPL support was first written to support only the earlier generations of
Allwinner SoCs, and was only really enabled on the A13 / GR8. However,
those old SoCs had a DMA engine that has been replaced since the A31 by
another DMA controller that is no longer compatible.

Since the code directly uses that DMA controller, it cannot operate
properly on the later SoCs, while the NAND controller has not changed.

There's two paths forward, the first one would have been to add support
for that DMA controller too, the second to just remove the DMA usage
entirely and rely on PIO.

The later has been chosen because CPU overload at this stage is not an
issue and it makes the driver more generic, and easier to understand.

This situation turns out to lead to a run time freeze with certain

mtd: nand: sunxi: fix ECC strength choice
When the requested ECC strength does not exactly match the strengths
supported by the ECC engine, the driver is selecting the closest
strength meeting the 'selected_strength > requested_strength'
constraint. Fix the fact that, in this particular case, ecc->strength
value was not updated to match the 'selected_strength'.

For instance, one can encounter this issue when no ECC requirement is
filled in the device tree while the NAND chip minimum requirement is not
a strength/step_size combo natively supported by the ECC engine.

e8d5291824 core: ofnode: Fix translation for #size-cells == 0
Commit 286ede6 ("drivers: core: Add translation in live tree case") made
dev_get_addr always use proper bus translations for addresses read from
the device tree. But this leads to problems with certain busses, e.g.
I2C busses, which run into an error during translation, and hence stop
working.

It turns out that of_translate_address() and fdt_translate_address()
stop the address translation with an error when they're asked to
translate addresses for busses where #size-cells == 0 (comment from
drivers/core/of_addr.c):

 * Note: We consider that crossing any level with #size-cells == 0 to mean
 * that translation is impossible (that is we are not dealing with a value
 * that can be mapped to a cpu physical address). This is not really specified
 * that way, but this is traditionally the way IBM at least do things

To fix this case, we check in both the live-tree and non-live tree-case,
whether the bus of the device whose address is about to be translated
has size-cell size zero. If this is the case, we just read the address
as a plain integer and return it, and only apply bus translations if the
size-cell size if greater than zero.

0237448a71 arm64: a37xx: pinctrl: Fix gpio pin offset in register
For armada_37xx_update_reg(), the parameter offset should be pointer so
that it can be updated, otherwise offset will keep old value, and then
when offset is larger than or equal to 32 the mask calculated by
"BIT(offset)" will be 0 in gpio chip hook functions, it's an error,
this patch set offset parameter of armada_37xx_update_reg() as pointer.

23626cac4b arm64: a37xx: pinctrl: Fix the pin 23 on south bridge
Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.

Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.

The bug was visible when the gpio regulator used the gpio 23, the whole
rgmii group was setup to gpio which broke the Ethernet support on the
Armada 3720 DB board. Thanks to this patch, the UHS SD cards (which need
the vqmmc) _and_ the Ethernet work again.
