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).

When DM_REGULATOR is enabled, the driver attempts to call
regulator_autoset() which expects the regulators to be on at boot
and/or always on and fails if they are not true.
For a more generic approach, this patch just calls
regulator_set_enable() which shouldn't have such restrictions.

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

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.

During this time, it is not possible to transport any commands or data

Some Allwinner clock devices have parent clocks and reset gates itself,
which need to be activated for them to work.
Add some code to just assert all resets and enable all clocks given.
This should enable the A80 MMC config clock, which requires both to be
activated. The full CCU devices typically don't require resets, and have
just fixed clocks as their parents. Since we treat both as optional and
enabling fixed clocks is a NOP, this works for all cases, without the need
to differentiate between those clock types.

register value checks if the requested value is above the maximum
and uses this maximum if so. The calculation of this maximum uses
the register width, but the check itself does not. It uses a hardcoded
value of 0xf, which is too low in case of the 5-bit clock (0x1f).
This detail was probably lost during driver unification.
Effect (only for KSZ9031 clock skews): For values greater 900 (== 0ps),
this silently results in 1860 (== +960ps) instead of the requested one.
Fix the check by using the bit width instead of hardcoded value(s).

The designware driver has a bug in setting the tx length into the dma
descriptor: it always or's the length into the descriptor without
zeroing out the length mask before.
This results in occasional packets being transmitted with a length
greater than they should be (trailer). Due to the nature of Ethernet
allowing such a trailer, most packets seem to be parsed fine by remote
hosts, which is probably why this hasn't been noticed.
Fix this by correctly clearing the size mask before setting the new
length.

The Armada 37xx watchdog driver was recently accepted for mainline
kernel by watchdog subsystem maintainer, but the driver works a little
different than the one in U-Boot. This patch fixes this.
In the previous implementation there was a tiny period of time when the
watchdog was disabled and the system was vulnerables - this was during
pinging, which was done by disabling, setting, and enabling the counter.
Now pinging is done without disabling the watchdog. We use 2 counters:
Counter 1 is the watchdog counter - on expiry, the system is reset.
Counter 0 is used to reset Counter 1 to start counting from the set
timeout again. So Counter 1 is set to be reset on Counter 0 expiry event
event and pinging is done by forcing an immediate expiry event on
Counter 0.

If _debug_uart_putc() is called before _debug_uart_init(), the

As this can happen via a printf sneaking in before the port calls
debug_uart_init(), introduce a config option to ignore characters
before the debug uart is initialized.
This is done by reading the baudrate divisor and aborting if is zero.
The Kconfig option is required as reading the baudrate divisor does

The mmc_select_mode_and_width() function can be called while the card
is in HS200/HS400 mode and can be used to downgrade the card to lower
mode, e.g. HS. This is used for example by mmc_boot_part_access_chk()
which cannot access the card in HS200/HS400 mode and which is in turn
called by saveenv if env is in the MMC.
In such case, forcing the card clock to legacy frequency cannot work.
Instead, the card must be switched to HS mode first, from which it can
then be reprogrammed as needed.
However, this procedure needs additional code changes, since the current
implementation checks whether the card correctly switched to HS mode in
mmc_set_card_speed(). The check only expects that the card will be going
to HS mode from lower modes, not from higher modes, hence add a parameter
which indicates that the HS200/HS400 to HS downgrade is happening. This
makes the code send the switch command first, reconfigure the controller
next and finally perform the EXT_CSD readback check. The last two steps
cannot be done in reverse order as the card is already in HS mode when
the clock are being switched on the controller side.

The ethsys contains not only the clock gating controller, but also the
reset controller for the whole ethernet subsystem and its components.
This patch adds binding of the reset controller so that the ethernet node
can have references on it.

which is caused by the following infinite loop inside esdhc_send_cmd_common()
while (!(esdhc_read32(®s->irqstat) & flags))

Instead of looping forever, provide an exit path so that a timeout
error can be propagated in the case irqstat does not report
any interrupts, which may happen when no eMMC is populated on
board.

This reverts commit a7f4b4b344.
As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:
1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)
2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).
3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).
As we are very close to release - please revert this commit.

Fixes commit 0131162439 ("dm: usb: create a new UCLASS ID for USB gadget
devices")
The UCLASS_DRIVER for id UCLASS_USB_GADGET_GENERIC needs to be declared
even for platforms that do not enable DM_USB_GADGET. Otherwise the driver
for their usb peripheral controller fails to bind.

dfu, fastbot and other usb gadget commands take the USB port index as a
parameter. Currently this index is assigned in the order of the driver
bindings.
Changing this behavior using the SEQ_ALIAS feature. This option assign to
the device a SEQ number based on its alias (if it exists)
To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing
naming convention: use "usb" for the name of the gadget UCLASS_DRIVER
(same as for the UCLASS_USB).
If no alias is provided, then the index falls back to the order in which
the bindings took place.

Existing clock configure code has been followed based on the
legacy MMC dt node definitions and it cannot work with recent
dts(i) sync from Linux.
So, add clock configure code for Allwinner platforms which support
DM_MMC and eventually this will drop once CLK support is in Mainline.

priv data has not been allocated when doing bind, so it is
wrong to use dev_get_priv in bind call back.
Let's switch to use platdata in the driver to fix the issue.
