bba516a772 pinctrl: rzg2l: Support Ethernet TXC output enable
On the RZ/G2L SoC family, the direction of the Ethernet TXC/TX_CLK
signal is selectable to support an Ethernet PHY operating in either MII
or RGMII mode. By default, the signal is configured as an input and MII
mode is supported. The ETH_MODE register can be modified to configure
this signal as an output to support RGMII mode.

As this signal is be default an input, and can optionally be switched to
an output, it maps neatly onto an `output-enable` property in the device
tree.

215663f5e4 pinctrl: rzg2l: Support 2.5V PVDD for Ethernet interfaces
The Ethenet interfaces on the Renesas RZ/G2L SoC family can operate at
multiple power supply voltages: 3.3V (default value), 2.5V and 1.8V.

rzg2l_pinconf_set() is extended to support the 2.5V setting, with a
check to ensure this is only used on Ethernet interfaces as it is not
supported on the SD & QSPI interfaces.

While we're modifying rzg2l_pinconf_set(), drop the unnecessary default
value for pwr_reg as it is set in every branch of the following if
condition.

a0c8e3cfba Merge patch series "led: update LED boot/activity to new property implementation"
Christian Marangi <ansuelsmth@gmail.com> says:

This series is split in 2 part.

While adapting the LED boot and activity code to the new property
accepted by Rob in dt-schema repository, a big BUG was discovered.

The reason wasn't clear at start and took me some days to figure it
out.

This was triggered by adding a new phandle in the test.dts to
introduce test for the new OPs.

This single addition caused the sandbox CI test to fail in the
dm_test_ofnode_phandle_ot test.

This doesn't make sense as reverting the change made the CI test
to correctly finish. Also moving the uboot node down
after the first phandle (in test.dts the gpio one) also made
the CI test to correctly finish.

A little bit of searching and debugging made me realize the
parse phandle OPs didn't support other.dts at all and they
were still referencing phandle index from test.dts.
(more info in the related commit)

In short the test was broken all along and was working by
pure luck. The first 4 patch address and fix the problem for good.

The other 4 patch expand and address the property change for
LED boot/activity.

Posting in a single series as changes are trivial and just
to speedup review process. (and also because the second
part depends on the first)

All CI tested with azure pipeline.

1614347036 dm: core: implement oftree variant of parse_phandle OPs
Implement oftree variant of parse_phandle OPs.

There is currently a very hidden and laten BUG with parse_phandle OPs
that doesn't permit the support of multiple DTS in a system. One usage
example if sandbox with the usage of other.dts

The BUG is only present on live scenario where of_... OPs are used and
it's not present when fdt... OPs are used.

This is caused by an assumption made in __of_parse_phandle_with_args,
with the of_find_node_by_phandle call that pass the first arg as NULL.

This makes of_find_node_by_phandle use the default root node of the
system and doesn't permit the usage of alternative tree. This is correct
for normal system and also for the linux kernel where it's assumed a
single device tree.

It's problematic if other device tree needs to be used.

To fix this, introduce __of_root_parse_phandle_with_args to define a
root device tree for of_find_node_by_phandle.

Introduce all the variant OPs for this and in ofnode, the oftree OPs
following how it's done for other OPs with similar task.

For FDT scenario, ofnode_from_fdtdec_phandle_args is reworked to accept
a new variable, node and noffset_to_ofnode is used instead of
offset_to_ofnode. This is required to support multiple FDB blob to
calculate the correct of_offset of the ofnode.

fe76d868f7 Merge patch series "Add OPP_LOW support for J7200"
Aniket Limaye <a-limaye@ti.com> says:

This series adds OPP_LOW spec data in k3_avs driver and enables a config
option to select the OPP_LOW performance point.

J7200 SOC supports OPP_LOW and OPP_NOM as two Operating Performance
Points as per (7.5 Operating Performance Points) section in the
Datasheet [0].
- A72SS/MSMC at 2 GHz/1GHz operation must use OPP_NOM.
- A72SS/MSMC at 1 GHz/500 MHz operation can use OPP_NOM or OPP_LOW
  voltage (though OPP_LOW voltage is recommended to reduce power
  consumption).

The actual OPP voltage for the device is read from the efuse and
updated in k3_avs_probe().

The default j7200 devicetree and k3_avs driver set OPP_NOM spec
frequency and voltage.

In the board init file, if K3_OPP_LOW config is enabled, Check if
OPP_LOW AVS voltage read from efuse is valid and update frequency (A72
and MSMC) and voltage (VDD_CPU) as per the OPP_LOW spec.

5a5c5bf40a efi_loader: net: add support to send http requests and parse http headers
Add network-stack agnostic way to send an http request and
parse http headers from efi drivers. This uses wget as a
backend and communicates with it via efi_wget_info.

The function efi_net_do_request allocates a buffer on behalf of an
efi application using efi_alloc and passes it to wget to receive
the data. If the method is GET and the buffer is too small, it
re-allocates the buffer based on the last received Content-Length
header and tries again. If the method is HEAD it just issues one
request. So issuing a HEAD request (to update Content-Length) and
then a GET request is preferred but not required.

The function efi_net_parse_headers parses a raw buffer containing
an http header into an array of EFI specific 'http_header' structs.

When loaded from HTTP, the device path should account for it so that

abadcda24b bootstd: android: don't read whole partition sizes
The current implementation is reading the whole partition for boot and
vendor_boot image which can be long following the size of the
partition or the time to read blocks (driver/SoC specific).

For example with mediatek mt8365 EVK board, we have a 64MiB boot
partition and the boot image flashed in this partition is only 42MiB.
It takes ~8-9 secs to read the boot partition.

Instead we can retrieved the boot image and vendor boot image size
with these new functions:
- android_image_get_bootimg_size
- android_image_get_vendor_bootimg_size
Use these information and read only the necessary.

By doing this with mt8365 EVK board, we read boot image in ~5 secs.

fec_mii_setspeed() calls fec_get_clk_rate with NULL pointer

880fcc49eb Merge patch series "Fix device removal order for Apple dart iommu"
Janne Grunau <j@jannau.net> says:

Starting with v2024.10 dev_iommu_dma_unmap calls during device removal
trigger a NULL pointer dereference in the Apple dart iommu driver. The
iommu device is removed before its user. The sparsely used DM_FLAG_VITAL
flag is intended to describe this dependency. Add it to the driver.

Adding this flag is unfortunately not enough since the boot routines
except the arm one simply remove all drivers. Add and use a new function
which calls
    dm_remove_devioce_flags(DM_REMOVE_ACTIVE_ALL | DM_REMOVE_NON_VITAL);
    dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);
to ensure this order dependency is head consistently.

dabaa4ae32 dm: Add dm_remove_devices_active() for ordered device removal
This replaces dm_remove_devices_flags() calls in all boot
implementations to ensure non vital devices are consistently removed
first. All boot implementation except arch/arm/lib/bootm.c currently
just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result
in crashes when dependencies between devices exists. The driver model's
design document describes DM_FLAG_VITAL as "indicates that the device is
'vital' to the operation of other devices". Device removal at boot
should follow this.

Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL |
DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which
does this.

Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI
boot. The xhci-pci (driver which depends on the IOMMU to work) removes
its mapping on removal. This explodes when the IOMMU device was removed
first.

dm_remove_devices_flags() is kept since it is used for testing of
device_remove() calls in dm.

- UFS support is enabled for SC7280 and SM8150 platforms.
- Qualcomm dt-bindings headers are all dropped in favour of
  dts/upstream.
- The SMMU driver now correctly handles stream ID 0 and is disabled in
  EL2.
- Initial support for capsule updates (using the new dynamic UUIDs) is
  added for the RB3 Gen 2 board alongside a new SCSI backend for DFU.
- CONFIG_PINCONF is enabled in qcom_defconfig.
- The vqmmc supply is now enabled for sdcard support on boards that need
  it.
- A quirk is added for reading GPIOs on the PM8550 PMIC

treewide: remove Qualcomm dt-binding headers that are available upstream
Some dt-binding headers mask the upstream ones which can lead to build
failures, or worse: super weird bugs, if they get out of sync.

Remove these headers so our devicetree and binding headers will both be
in sync with upstream.

mach-snapdragon: implement capsule update support
Qualcomm boards flash U-Boot a variety of partitions, implement support
for determining which slot U-Boot is running from, finding the correct
partition for that slot and configuring the appropriate DFU string.

Initially, we only support the RB3 Gen 2 where U-Boot is flashed to the
UEFI partition, and ignore handling of slots. In the future we will
additionally support booting U-Boot from other partitions (e.g. boot)
and correct handling for A/B.

disk: expose partition type flags
GPT partition tables include two bytes worth of vendor defined
attributes, per partition. ChromeOS and Qualcomm both use these (with
different encoding!) to handle A/B slot switching with a retry counter.

Expose these via the disk_partition struct so that they can be parsed by
the relevant board code.

This will be used on Qualcomm boards to determine which slot we're
booting on so that we can flash capsule updates to the correct one.

dfu: add scsi backend
This is extremely similar to the MMC backend, but there are some notable
differences.

Works with a DFU string like

    scsi 4=u-boot-bin part 11

Where "4" is the SCSI dev number (sequential LUN across all SCSI devices)
and "11" is the partition number.

Also remove jffs to MTD map but MTD map is for example that's why it won't
