6fb1eb1b76 arm: socfpga: gen5 enable designware_socfpga
Enable the socfpga specific designware ethernet driver by default for
socfpga by implying it when enabling CONFIG_ETH_DESIGNWARE for a
MACH_SOCFPGA config.

This is required to remove the hacky reset and phy mode handling in
arch/arm/mach-socfpga.

4f1267cea1 net: designware: socfpga: adapt to Gen5
This driver was written for Arria10, but it applies to Gen5, too.

The main difference is that Gen5 has 2 MACs (Arria10 has 3) and the
syscon bits are encoded in the same register, thus an offset is needed.

This offset is already read from the devicetree, but for Arria10 it is
always 0, which is probably why it has been ignored. By using this
offset when writing the phy mode into the syscon regiter, we can use
this driver to set the phy mode for both of the MACs on Gen5.

Since the PHY mode bits in sysmgr are the same even for Stratix10,
let's drop the detection of the sub-mach by checking compatible
version and just use the same code for all FPGAs.

To work correctly, this driver depends on SYSCON and REGMAP, so select
those via Kconfig when it is enabeld.

Tested on socfpga_socrates (where the 2nd MAC is connected, so a shift
offset is required).

where is exactly describing i2c bus topology.
By moving to DM case i2c mux buses are using names from DT and because
i2c-muxes describing sub busses with the same names like i2c@0, etc it
is hard to identify which bus is where.
Linux is adding topology information to i2c-mux busses to identify them
better.
This patch is doing the same and composing bus name with topology
information.

cc4a224af2 power: regulator: Introduce regulator_set_enable_if_allowed api
regulator_set_enable() api throws an error in the following three cases:
- when requested to disable an always-on regulator
- when set_enable() ops not provided by regulator driver
- when enabling is actually failed.(Error returned by the regulator driver)

Sometimes consumer drivers doesn't want to track the first two scenarios
and just need to worry about the case where enabling is actually failed.
But it is also a good practice to have an error value returned in the
first two cases.

So introduce an api regulator_set_enable_if_allowed() which ignores the
first two error cases and returns an error as given by regulator driver.
Consumer drivers can use this api need not worry about the first two
error conditions.

f388564965 dm: device: fail uclass_find_first_device() if list_empty
While uclass_find_device() fails with -ENODEV in case of list_empty
strangely uclass_find_first_device() returns 0.

Fix uclass_find_first_device() to also fail with -ENODEV instead.

351a4aa050 mmc: omap_hsmmc: Workaround errata regarding SDR104/HS200 tuning failures (i929)
Errata i929 in certain OMAP5/DRA7XX/AM57XX silicon revisions
(SPRZ426D - November 2014 - Revised February 2018 [1]) mentions
unexpected tuning pattern errors. A small failure band may be present
in the tuning range which may be missed by the current algorithm.
Furthermore, the failure bands vary with temperature leading to
different optimum tuning values for different temperatures.

As suggested in the related Application Report (SPRACA9B - October 2017
- Revised July 2018 [2]), tuning should be done in two stages.
In stage 1, assign the optimum ratio in the maximum pass window for the
current temperature. In stage 2, if the chosen value is close to the
small failure band, move away from it in the appropriate direction.

ba8ba69b66 drivers: serial: dm: Enable DM_FLAG_PRE_RELOC in SBSA pl011 uart driver
The DM_FLAG_PRE_RELOC shall be enabled in SBSA PL011 uart driver
as this driver is used in NXP based SoCs

It is necessary to have Serial console running before relocation

The !CONFIG_IS_ENABLED(OF_CONTROL) [*] check is set as "workaround"
for DM problem : 4687919684

This flag is set if board does not support device-tree and using
platform data, In DM Model either of device tree or platform data
can be used to fetch device configuration

It is possible to use SBSA UART with CONFIG_DM_SERIAL but witout
corresponding device tree description (OF_CONTROL)

Other board/SoCs have this flag set unconditionally

6892550c4a mmc: Do not poll using CMD13 when changing timing
When using CMD6 to switch eMMC card timing from HS200/HS400 to HS/legacy,
do not poll for the completion status using CMD13, but rather wait 50mS.

Once the card receives the CMD6 and starts executing it, the bus is in
undefined state until both the card finishes executing the command and
until the controller switches the bus to matching timing configuration.
During this time, it is not possible to transport any commands or data
across the bus, which includes the CMD13.

cbbe69483e mmc: tmio: renesas: Add 1uS delay after DMA completion on older IPs
The internal DMAC asserts DMA transfer end bit too early on older
version of the TMIO IPs which use bit 17 for DTRAEND. Add 1uS
delay after the completion of DMA transfer and before invalidating
the cache to let the DMAC fully complete the transfer. Otherwise,
it could happen that the last few bytes of a transferred data are
not available.

A test case to trigger this behavior is the following command, ran
on the U-Boot command line, with Sandisk 16 GiB UHS-I card inserted
into SDHI slot 0 and with first partition being of type FAT:
=> while true ; do mmc rescan ; fstype mmc 0:1 ; done

Different versions of the SDHI core use either bit 17 or bit 20 for the
DTRAEND indication, which can differ even between SoC revisions. Make
the DTRAEND bit position part of the driver private data, so that the
probe function can set this accordingly. Set this to 20 on Socionext
SoCs and either 17 or 20 on Renesas SoCs, depending on the SoC.

I2C supports adding adapters using either a dynamic or fixed id. The
latter is provided by aliases in the DT case. To prevent id collisions
of those two types, install this function which gives us the highest
fixed id, so we can then let the dynamically created ones come after
this highest number.
