65a25b2086 mmc: sdhci: drop CONFIG_ from CONFIG_SDHCI_CMD_MAX_TIMEOUT
No need for per-SoC adjustment for this parameter.  It should be
determined by the slowest hardware.  Currently, no board overrides
this CONFIG, so 3.2 sec is large enough.  (If not, we can make it
even larger.)

d8ce77b28c mmc: sdhci: drop CONFIG_ from CONFIG_SDHCI_CMD_DEFAULT_TIME
This CONFIG is not configurable since it is not guarded by #ifndef.
Nobody has complained about that, so there is no need to keep it as
a CONFIG option.

7c22e26ec5 sunxi: musb: Re-init musb controller on repeated probe calls
With sunxi-musb musb_lowlevel_init() can fail when a charger; or no cable
is plugged into the otg port.

To avoid leaking the struct musb allocated by musb_init_controller()
on repeated musb_usb_probe() calls, we were caching its result.
But musb_init_controller() does more, such as calling sunxi_musb_init()
which enables the clocks.

Not calling sunxi_musb_init() causes the musb controller to stop working
after a "usb reset" since that calls musb_usb_remove() which disables the
clocks.

This commit fixes this by removing the caching of the struct returned
from musb_init_controller(), it replaces this by free-ing the allocated
memory in musb_usb_remove() and calling musb_usb_remove() on
musb_usb_probe() errors to ensure proper cleanup.

While at it also make musb_usb_probe() and musb_usb_remove() static.

76f1f38816 Use separate options for TPL support
At present TPL uses the same options as SPL support. In a few cases the board
config enables or disables the SPL options depending on whether
CONFIG_TPL_BUILD is defined.

With the move to Kconfig, options are determined for the whole build and
(without a hack like an #undef in a header file) cannot be controlled in this
way.

Create new TPL options for these and update users. This will allow Kconfig

47a79f657e usb: uniphier: remove UniPhier xHCI driver and select DM_USB
This driver has not been converted to Driver Model, and it is an
obstacle to migrate other block device drivers.  Remove it for now.

The UniPhier SoCs already use a DM-based EHCI driver, so now
ARCH_UNIPHIER can select DM_USB.

41d1258ace net: asix: Fix AX88772B when used with DriverModel
A previous patch (net: asix: fix operation without eeprom) added a
two-byte shift to the packet buffer when receiving a packet on the
AX88772B.

This shift was not included when the driver was updated to work with
DriverModel. Testing on a Marvell DB-88F6820-ACM showed that the adapter
was not functioning correctly (EHCI timeouts).

This patch brings the two-byte shift to the DriverModel implementation
of ops->recv (asix_eth_recv).

Testing on the same board, we were able to TFTP a file over and confirm
that the crc32 was correct.

601147b06a serial: bcm283x_mu: Detect disabled serial device
On the raspberry pi, you can disable the serial port to gain dynamic frequency
scaling which can get handy at times.

However, in such a configuration the serial controller gets its rx queue filled
up with zero bytes which then happily get transmitted on to whoever calls
getc() today.

This patch adds detection logic for that case by checking whether the RX pin is
mapped to GPIO15 and disables the mini uart if it is not mapped properly.

That way we can leave the driver enabled in the tree and can determine during
runtime whether serial is usable or not, having a single binary that allows for
uart and non-uart operation.

421c98d7d2 sunxi: display: Use PWM to drive backlight where applicable
When the backlight's pwm input is connected to a pwm output of the SoC,
actually use pwm to drive the backlight.

The mean reason for doing this is to fix the backlight turning off
for aprox. 1 second while the kernel is booting. This is caused by
the kernel actually using pwm to drive the backlight, so that it
can dim the backlight. First the pwm driver loads and switches the
pinmux for the pin driving the backlight's pwm input to the pwm
controller. Then about 1s later the actual backlight driver loads
and tells the pwm driver to actually update the pwm settings, which
have a power-on-reset value of "off".

An additional advantage is that this allows us to initatiate the
backlight at 80%, which is the kernel default, avoiding a brightness
change while the kernel loads.

4832c7f5f7 spi: tegra: fix hang in set_mode()
In tegra20_slink.c, the set_mode() function may be executed before the
SPI bus is claimed the first time, and hence the clocks to the SPI
controller may not be running. If so, any register read/write at this
time will hang the CPU. Fix this by ensuring the clock is running as soon
as the driver is probed. This is observed on the Tegra30 Beaver board.

Apply the same clock initialization fix to all other Tegra SPI drivers so
that if set_mode() is ever implemented there, the same bug will not appear.
Note that tegra114_spi.c already operates in this fashion.

The clock manipulation code is copied from claim_bus() to probe() rather
than moved. This ensures that any calls to set_speed() take effect; the
clock can't be set once during probe and left unchanged.

The spatch series converting legacy drivers from miiphy_register to
mdio_register changed the return convention of the davinci_emac internal
MDIO accessors, making the internal code relying on it misbehaving:
no mdiodev get registered and U-Boot crashes when using net cmds in the
context of the old legacy net API.

ATM davinci_emac_initialize and cpu_eth_init don't return a proper value
in that case but fixing them would not avoid the crash.

This change is just a follow-up to the spatch pass, the MDIO accessors
of the mdiodev introduced by the spatch pass retain their proper values.
