A bunch of code calls info->dev, mostly dev_* messages and devm_kzalloc.
The former can be passed a NULL device and _dev_printk handles this just
fine.
The latter ignores the dev argument whenever !CONFIG_IS_ENABLED(DEVRES)
which was true in most cases until we made CONFIG_DEVRES mandatory for
U-Boot proper in commit 217cf656e249 ("dm: core: Default to using DEVRES
outside of xPL"). Failing to set info->dev before it's used by
devm_kzalloc results in crashes, therefore let's set info->dev before it
can be used.

single_add_gpio_func() calls ofnode_parse_phandle_with_args() once per
gpio-range entry. With a flat device tree, every call re-iterates the
property from index 0 and, because cellname is set, performs an
fdt_node_offset_by_phandle() (a full-FDT scan) at every step. The total
cost is therefore quadratic in the number of entries and proportional to
the size of the device tree.
The impact depends on when the pinctrl is probed. On the J722S EVM
defconfig, pinctrl@f4000 (main_pmx0, the SoC's stock 7-entry gpio-range)
is probed after relocation (caches on): single_add_gpio_func() takes
~18 ms there and ~1 ms with this change. When the node is probed before
relocation (caches off) the same parse takes hundreds of ms; on a board
that probes it pre-relocation and runs LPDDR4 clocked down it reached
723 ms, cut to 22 ms here. Any pinctrl-single user with a populated
gpio-range property pays this cost.
The phandle target is never dereferenced by this function (only the
argument cells are stored), so resolve it only for the first entry to
learn the per-entry cell count, then read the argument cells directly
with ofnode_read_u32_index() and allocate the ranges in one block. A
zero phandle still terminates the list, as in the original loop. This
follows the existing pinctrl-single,gpio-range usage observed in current
DTs, where entries use the same provider and therefore a uniform
per-entry cell count.

Beside a fix for a long standing bug in the A80 eMMC code, this adds
SPI booting support for the Allwinner A523/A527/T527 class of boards.
The second major feature is support for the secondary Ethernet controller
on that same SoC. This might not be as important as for the kernel (I
doubt that U-Boot acts as a router), but for once some boards only connect
the secondary EMAC, and on others people might have the boot server only
reachable via this port.
There are some smaller fixes and improvements still queued up, but they
need some more testing and are minor, so can land a bit later.
The world build timed out, but the rest passed, and I booted that briefly
on an A523 board with two Ethernet ports.

Add pinctrl driver for Spacemit K1 SoC.

Billy Tsai <[email protected]> says:
The AST2700 is Aspeed's 7th-generation BMC SoC with a dual-die
architecture: SoC0 (CPU die) and SoC1 (I/O die) each have their own SCU
with independent multi-function pin controls. Initial AST2700 platform
support is already merged in next, including the ast2700.dtsi pinctrl0
and pinctrl1 nodes, but no pinctrl driver backs them yet.
This series adds one pinctrl driver per die, each followed by a patch
adding its pin configuration support. Both drivers use the generic
pinctrl framework and are compatible with the Linux kernel device tree
bindings, using the same group and function names as the Linux
aspeed,ast2700-soc0/soc1-pinctrl drivers so pin states can be shared
between the kernel and U-Boot device trees.
Patch 1 adds the SoC0 driver, which models each (function, group) pair
as a flat register mask/value table covering eMMC, VB, VGA DDC, JTAG
master port select, PCIe RC PERST and USB2/USB3 port routing. Patch 2
adds SoC0 pin configuration support: every GPIO18A/GPIO18B ball has
its own IO control register providing a 3 mA to 41 mA drive strength
selector and bias control.
Patch 3 adds the SoC1 driver, porting the per-pin 4-bit multi-function
selector scheme (220 pins, 238 groups, 217 functions) together with
the virtual pins for PCIe RC2 PERST, the USB2 port C/D mode and SGMII
controls. Patch 4 adds SoC1 pin configuration support: a per-pin bias
enable bit and sparse 2-bit drive strength fields (4 mA to 16 mA in
4 mA steps) mirroring the Linux driver layout.
The bias-disable, bias-pull-down, bias-pull-up and drive-strength
properties can be applied per pin or per group. Both drivers implement
gpio_request_enable so the GPIO driver can reclaim pins through the
gpio-ranges already present in ast2700.dtsi, and provide
get_pin_muxing so "pinmux status" reports the active signal of every
pin.

The SoC1 SCU provides a bias enable bit per pin in the registers at
0x480 (setting the bit disables the bias; the pull direction is fixed
in silicon) and 2-bit drive strength fields at 0x4C0 selecting 4 mA to
16 mA in 4 mA steps. The pin-to-field mapping of the drive strength
registers is sparse and non-linear, so it is kept in a lookup table
mirroring the Linux driver; pins without an entry reject
drive-strength with -ENOTSUPP.
Support the bias-disable, bias-pull-down, bias-pull-up and
drive-strength properties per pin and per group, and select PINCONF so
the generic pinctrl framework parses them.

Add the pinctrl driver for the AST2700 SoC1 (I/O) die.
Unlike previous Aspeed generations, the SoC1 SCU assigns every pin a
4-bit multi-function selector field in a contiguous register range
starting at SCU 0x400, eight pins per register. Only bits [2:0] of
each field select the function; bit 3 is reserved read-only and must
not be written. The driver therefore keeps per-pin group tables and
per-function mux values, mirroring the Linux
aspeed,ast2700-soc1-pinctrl driver, and shares the same device tree
bindings: 220 pins, 238 groups and 217 functions with identical names,
so pin states written for the Linux driver work unmodified.
A few controls live outside the pin-indexed range and are handled as
virtual pins: PCIERC2_PERST (SCU 0x908), the USB2 port C/D mode fields
(SCU 0x3B0) and SGMII0 (SCU 0x47C).
The gpio_request_enable hook restores a pin to GPIO by writing mux
value 0, except for the ADC-capable balls W17..AB19 where function 1
selects GPIO and 0 selects the ADC input.

Each GPIO18A/GPIO18B ball has its own IO control register starting at
SCU 0x480, providing a 4-bit drive strength selector (3 mA to 41 mA in
hardware-defined steps), a bias enable bit and a pull direction bit.
Extend the group table with the pin members of the ball-backed groups
so bias-disable, bias-pull-down, bias-pull-up and drive-strength
properties can be applied per group as well as per pin. The routing
groups (USB, JTAG, PCIe RC) have no package balls and reject pin
configuration with -ENOTSUPP.
Select PINCONF so the generic pinctrl framework parses the pin
configuration properties.

The AST2700 is a dual-die BMC SoC: SoC0 (CPU die) and SoC1 (I/O die)
each have their own SCU with independent multi-function pin controls.
Add the pinctrl driver for the SoC0 die. The driver uses the generic
pinctrl framework and is compatible with the Linux kernel device tree
bindings, i.e. pin states are described with the same "function" and
"groups" properties and the same names as the Linux
aspeed,ast2700-soc0-pinctrl driver.
Unlike the older AST2500/AST2600 SCUs where each signal is enabled by
independent bits, the SoC0 mux selections mix single-bit enables
(eMMC, VGA DDC, VB strap), multi-bit selector fields (JTAG master port
select, USB2/USB3 port routing) and reset-control bits (PCIe RC
PERST). Model each (function, group) pair as one register
mask/value write so all of them fit a single flat table.
The gpio_request_enable hook releases the GPIO18A/GPIO18B pins to GPIO
mode by clearing every signal enable bit that claims the pin, matching
the Linux driver behaviour.

Replace snprintf() with scnprintf() in the MediaTek pinctrl driver.
snprintf() returns the number of characters that _would_ have been
written if the buffer were large enough, while scnprintf() returns the
number of characters actually written to the buffer. Since we use the
return value to advance the buffer pointer, we need to use scnprintf()
to have the correct pointer arithmetic.

The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

Fix setting pinconf bias for MT8189.
Using mtk_pinconf_bias_set_v1() was wrong because MT8189 does not have
PULLEN/PULLSEL registers. It has PU and PD registers for most pins.
MSDC pins need special handling since they have PUPD/R1/R0 registers.
I2C pins need special handling since they have PU/PD/RSEL registers.
New groups are added for MSDC and I2C pins and the bias_set callback
is now set appropriately for all groups.
A new table is needed for the RSEL registers since those were missing.
Some new macros are introduced to avoid repeating the same info many

This driver adds the base support of pinctrl over SCMI. The driver
does two main things. First, it allows you to configure the initial
pin states. Secondly, it's used a base to build a GPIO driver on
top of it.
To configure the states then add a pinmux config to the scmi_pinctrl
section:
scmi_pinctrl: protocol@19 {
reg = <0x19>;
pinmux1: pinmux_test {
pinmux = <0 1 0xFFFFFFFF 18 1
0 2 0xFFFFFFFF 18 1
0 3 0xFFFFFFFF 18 1>;
function = "f_gpio1";
groups = "grp_1", "grp_3";
};
};
Under linux the pinctrl subsystem will parse the function and group
properties and use that to handle muxing. However, under u-boot the
pin muxing is done using the "pinmux" property, which feeds raw SCMI
pinctrl PINCTRL_SETTINGS_CONFIGURE commands to the server. The
numbers are: selector, identifier, function_id, config_type, and
config_value. In the example above, it sets pins 1, 2, and 3 to 1.
The linux-kernel ignores this pinmux property.
