The driver already creates a 2nd gpio bank by reading the 2nd node
from DT, so this is quite a simple change to support the 2nd bank.

- network device name is now representative

On ls2080 we have a separate network fabric component which we need to
shut down before we enter Linux (or any other OS). Along with that also
comes configuration of the fabric using a description file.
Today we always stop and configure the fabric in the boot script and
(again) exit it on device tree generation. This works ok for the normal
booti case, but with bootefi the payload we're running may still want to
access the network.
So let's add a new fsl_mc command that defers configuration and stopping
the hardware to when we actually exit U-Boot, so that we can still use
the fabric from an EFI payload.
For existing boot scripts, nothing should change with this patch.

OHCI has a known limitation of allowing only 32-bit DMA buffer
addresses, so we have a lot of u32 variables around, which are assigned
to pointers and vice versa. This obviously creates issues with 64-bit
systems, so the compiler complains here and there.
To allow compilation for 64-bit boards which use only memory below 4GB
anyway (and to avoid more invasive fixes), adjust some casts and types
and assume that the EDs and TDs are all located in the lower 4GB.
This fixes compilation of the OHCI driver for the Pine64.

Make sure the driver writes the cmd_data register only once per
read transfer instead of doing so potentially repeatedly.
In case the read transfer didn't finish quickly enough, the loop
in the driver code would spin fast enough to write the same value
into the cmd_data register again before re-checking whether the
transfer completed, which would cause another spurious read transfer
on the bus.

The initial design of the UniPhier clk driver for U-Boot was not

Marek reports warnings in UniPhier pinctrl drivers when compiled by
GCC 6.x, like:
drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning:
'usb3_muxvals' defined but not used [-Wunused-const-variable=]
static const int usb3_muxvals[] = {0, 0};
^~~~~~~~~~~~
My intention here is to compile minimum set of pin data for SPL to
save memory footprint, but GCC these days is clever enough to notice
unused data arrays.
We can fix it by sprinkling around __maybe_unused on those arrays,
but I did not do that because they are counterparts of the pinctrl
drivers in Linux. All the pin data were just copy-pasted from Linux
and are kept in sync for maintainability.
I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of
*_pins and *_muxvals and set their sum to an unused struct member.
This trick will satisfy GCC because the data arrays are used anyway,
but such data arrays will be dropped from the final binary because
the pointers to them are not used.

With this feature implemented, there is no point smsc95xx_init_common()

When programming, we use word index, so need to fix bank7/8 programming

USB ULPI PHY reset signals are typically active low. Consequently, they
should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in
the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use.
However, in DT properties that U-Boot does use, the value has been set to
0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot.
This change fixes the DT to correctly represent the HW, and fixes the
Tegra USB driver to cope with the fact that dm_gpio_set_value() internally
handles any inversions implied by the DT value GPIO_ACTIVE_LOW.

refactoring of the existing Tegra clock/clock code. The driver currently
only supports peripheral clocks, and avoids support for other clocks such
as PLLs and external clocks. This should be sufficient to convert over all

struct mmc_host is a Tegra-specific structure, but the name implies it's

Nothing needs access to this type except the MMC driver itself. Move the

Make sure all Tegra MMC functions are named tegra_mmc_*. Even though
they're all static, it's useful to have good naming so that symbol tables
are easy to interpret. A few functions aren't renamed by this patch since

TI QSPI has four 32 bit data registers which can be used to transfer 16
bytes of data at once. The register group QSPI_SPI_DATA_REG_3,
QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is
treated as a single 128-bit word for shifting data in and out. The bit
at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out
in case of 128 bit transfer mode. Therefore the first byte to be written
to flash should be at QSPI_SPI_DATA_REG_3[31-25] position.
Instead of writing 1 byte at a time when interacting with SPI NOR flash,
make use of all the four registers so that 16 bytes can be transferred
in one go.
With this patch, the flash write speed increases from ~250KBs/ to

Signed-off-by: Paul Burton <paul.burton@imgtec.com>
Device model drivers have previously been matched to FDT nodes by virtue
of being the first driver in the driver list to be compatible with the
node. This ignores the fact that compatible strings in the device tree
are listed in order of priority - that is, if we have a node with 2
compatible strings & a driver that matches each then we should always
probe the driver that matches the first compatible string.
Fix this by looping through the compatible strings for a node when
attempting to bind it in lists_bind_fdt and checking each driver for
a match of the first string, then each driver for a match of the second
string etc. Effectively this inverts the loops over compatible strings &
drivers.

In pci_uclass_pre_probe an attempt is made to detect whether the parent
of a device is a PCI device and that the device is thus a bridge. This
was being done by checking whether the parent of the device is of the
UCLASS_ROOT class. This causes problems if the PCI controller is a child
of some other non-PCI node, for example a simple-bus node.
For example, if the device tree contains something like the following
then pci_uclass_pre_probe would incorrectly believe that the PCI
controller is a bridge, with a PCI parent:
/ {
some_child {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <>;
pci_controller: pci@10000000 {
compatible = "my-pci-controller";
device_type = "pci";
reg = <0x10000000 0x2000000>;
};
};
};
Avoid this incorrect detection of bridges by instead checking whether
the parent devices class is UCLASS_PCI and treating a device as a bridge
when this is true, making use of device_is_on_pci_bus to perform this
test.

Previously ns16550 compatible UARTs probed via device tree have needed
their device tree nodes to contain a clock-frequency property. An
alternative to this commonly used with Linux is to reference a clock via
a phandle. This patch allows U-Boot to support that, retrieving the
clock frequency by probing the appropriate clock device.
For example, a system might choose to provide the UART base clock as a
reference to a clock common to multiple devices:
sys_clk: clock {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <10000000>;
};
uart0: uart@10000000 {
compatible = "ns16550a";
reg = <0x10000000 0x1000>;
clocks = <&sys_clk>;
};
uart1: uart@10000000 {
compatible = "ns16550a";
reg = <0x10001000 0x1000>;
clocks = <&sys_clk>;
};
This removes the need for the frequency information to be duplicated in
multiple nodes and allows the device tree to be more descriptive of the
system.

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.

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.

pinctrl_generic_set_state_subnode() returns an error for the top-level
node and pinctrl_generic_set_state() fails. Instead, return success so
that the child nodes are tried.

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.

Currently the command buffer gets allocated with a size of 32 bytes.
This causes warning messages on systems with cache lines bigger than
32 bytes:

Define command buffer to be at least 32 bytes, but more if cache

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.

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.
