fa3f16e450 Merge patch series "Add MT8195 support"
Julien Stephan <jstephan@baylibre.com> says:

This series adds basic support for Mediatek soc MT8195:
- clock driver
- watchdog
- add a new macro helper to define gate clock. Other driver can be
  cleaned later to use the new macro

Other driver will be added later.

It will also serve as basis for board support such as MT8395_EVK based
on MT8195.

Julien Stephan <jstephan@baylibre.com> says:

I recently submitted the clock driver for MT8188. I naively submitted a
driver that was ported from the kernel driver, and mostly work to boot a
kernel.

Recently David Lechner, added support for the clk dump command for
Mediatek clock drivers, so I used it to check the MT8188 and found
several issues fixed on this series:

- removed topckgen_cg, gates are now part of topckgen
- fixed several parents clocks
- added missing fixed clocks

While at it, I also refactored a bit the driver to improve readability,
and future additions to it.

Refactor some part of the driver to improve readability and future
additions:

- use CLK_TOP_NR_CLK for added clocks
- rename the id map to make it more clear that the map applies to top
  clocks only
- refactor the id map to improve readability
- xtal2_rate is only used for PLL clocks, so only the apmixedsys clock
  tree needs it. Remove it elsewhere.

e8dd062642 Merge patch series "Implement all missing SMBIOS types required by distro tooling"
Raymond Mao <raymondmaoca@gmail.com> says:

From: Raymond Mao <raymond.mao@riscstar.com>

This series finish the last missing puzzle of required SMBIOS types by:
1) Fixing duplicated handles when multiple instances exist in one type;
2) Implementing the rest of required types 9/16/17/19;
3) Adding version control when printing properties for all types.

Type 9/16/17/19 are generally DT-based, the idea is to write these tables
using a hybrid approach:
Explicit DT definitions under existing '/smbios/smbios' take precedence,
with fallback to scan and interpret values from the entire DT.

Moreover, all below APIs:
smbios_get_val_si()
smbios_get_u64_si()
smbios_add_prop_si()
are on top of sysinfo, thus allow vendors to get values from other
subsystems by implementing their own sysinfo driver if needed.

374896158b smbios: add support for dynamic generation of Type 16 table
This commit implements SMBIOS Type 16 (Physical Memory Array)
generation with a hybrid approach supporting both:

1. Explicit definition via Device Tree 'smbios' node:
   Child node under '/smbios/smbios/memory-array' will be used to
   populate as individual Type 16 structure directly.
   - Properties follow SMBIOS field names with lowercase letters and
     hyphen-separated words (e.g., 'memory-error-correction',
     'maximum-capacity', 'extended-maximum-capacity', etc.).
   - This method supports precise platform-defined overrides and system
     descriptions.

2. Fallback to automatic DT-based discovery:
   If child node under '/smbios/smbios/memory-array' does not exist,
   the implementation will:
   - Scan all top-level 'memory@' nodes to populate Type 16 structure with
     inferred size and location data.
   - Scan nodes named or marked as 'memory-controller' and parse
     associated 'dimm@' subnodes (if present) to extract DIMM sizes and
     map them accordingly.

This dual-mode support enables flexible firmware SMBIOS reporting while
aligning with spec-compliant naming and runtime-detected memory topology.

Type 16 support is under GENERATE_SMBIOS_TABLE_VERBOSE to avoid
increasing rom size for those platforms which only require basic SMBIOS
support.

9ddccb5144 Merge patch series "treewide: Clean up usage of DECLARE_GLOBAL_DATA_PTR"
Peng Fan (OSS) <peng.fan@oss.nxp.com> says:

This patch set primarily removes unused DECLARE_GLOBAL_DATA_PTR
instances.

Many files declare DECLARE_GLOBAL_DATA_PTR and include
asm/global_data.h even though gd is never used. In these cases,
asm/global_data.h is effectively treated as a proxy header, which is
not a good practice.

Following the Include What You Use principle, files should include
only the headers they actually depend on, rather than relying on
global_data.h indirectly. This approach is also adopted in Linux kernel
[1].

The first few patches are prepartion to avoid building break after
remove the including of global_data.h.

A script is for filtering the files:
list=`find . -name "*.[ch]"`
for source in ${list}
do
        result=`sed -n '/DECLARE_GLOBAL_DATA_PTR/p' ${source}`
        if [ "${result}" == "DECLARE_GLOBAL_DATA_PTR;" ]; then
                echo "Found in ${source}"

                result=`sed -n '/\<gd\>/p' ${source}`
                result2=`sed -n '/\<gd_/p' ${source}`
                result3=`sed -n '/\<gd->/p' ${source}`
                if [ "${result}" == "" ] && [ "${result2}" == "" ] && [ "${result3}" == "" ];then
                        echo "Cleanup ${source}"
                        sed -i '/DECLARE_GLOBAL_DATA_PTR/{N;/\n[[:space:]]*$/d;s/.*\n//;}' ${source}
                        sed -i '/DECLARE_GLOBAL_DATA_PTR/d' ${source}
                        sed -i '/global_data.h/d' ${source}

22aac1c5b4 clk: altera: agilex: Exclude AGILEX_L4_SYS_FREE_CLK from enable/disable operations
AGILEX_L4_SYS_FREE_CLK is a free-running clock with no gate control in
hardware, therefore attempting to enable or disable it is not applicable.

Update the clock driver to explicitly exclude this clock ID from
enable/disable operations by returning -EOPNOTSUPP in bitmask_from_clk_id()
and treating this as a no-op in the socfpga_clk_enable() and
socfpga_clk_disable() functions.

This prevents unnecessary register access for clocks that cannot be gated
and ensures clean handling when the clock is present in the device tree.

83f2843f20 socfpga: agilex: fix NAND clock handling
In v2025.10, the Agilex clock driver was updated to support
clk_enable() and clk_disable() using clock-ID based bitmasks.
However, only AGILEX_NAND_CLK was implemented, while the NAND DT
node still referenced both nand and nand_x clocks.

Since AGILEX_NAND_X_CLK is not defined in the clock driver or the
clock-ID specification, clk_enable() failed during NAND probe.
As a result, the Denali NAND controller never completed
initialization.

Fix this by mapping the NAND X clock to the existing l4_mp clock
bitmask, aligning the DT expectations with the clock driver and
restoring proper NAND controller initialization.

4f76c90bad mtd: spi-nor: winbond: Make sure w25q{01, 02}jv behave correctly
These chips are internally made of two/four dies with linear addressing
capabilities to make it transparent to the user that two/four dies were
used. There is one drawback however, the read status operation is racy
as the status bit only gives the active die status and not the status of
the other die. For commands affecting the two dies, it means if another
command is sent too fast after the first die has returned a valid
status (deviation can be up to 200us), the chip will get corrupted/in an
unstable state.

The solution adopted here is to iterate manually over all internal
dies (which takes about 30us per die) until all are ready. This approach
will always be faster than a blind delay which represents the maximum
deviation, while also being totally safe.

A flash-specific hook for the status register read had to be
implemented. Testing with the flash_speed benchmark in Linux shown no
difference with the existing performances (using the regular status read
core function).

As the presence of multiple dies is not filled in these chips SFDP
tables (the table containing the crucial information is optional), we
need to manually wire the hook.

This change is adapted from Linux.

df1875ea31 pinctrl: zynqmp: Add SPL support
Although the pinctrl pm requests are implemented in the PMU firmware,
PM_QUERY_DATA is actually implemented in ATF. In SPL (or when running in
EL3), ATF is not yet running, so we need to implement this API
ourselves. Do the bare minimum, allowing SPL to enumerate functions, but
don't bother with groups. Groups take up a lot of space, and can be
emulated with pins. For example, a node like

	display-port {
		mux {
			groups = "dpaux0_1";
			function = "dpaux0";
		};
	};

can be replaced by

	display-port {
		mux {
			pins = "MIO34", "MIO35", "MIO36", "MIO37";
			function = "dpaux0";
		};
	};

While this isn't backwards-compatible with existing devicetrees, it's
more than enough for SPL where we may only need to mux one or two pins.

Add SPL_PINCTRL_ZYNQMP to ensure there's no SPL size growth when pinctrl
is enabled in U-Boot but isn't necessary for SPL. The only config this
would affect is Kria, but SPL_PINCTRL_GENERIC is disabled so
SPL_PINCTRL_ZYNQMP is not selected.

Falls back to 'calibration' property if clock unavailable, and uses
default calibration if neither is present. Only writes calibration when
hardware register reads zero.

The calibration write previously in zynqmp_rtc_set() has been moved to
the probe function. The earlier implementation wrote calibration on
every time update to clear the tick counter, but since calibration is
now dynamically configured from clock framework or device tree during probe,
it only requires one-time initialization. This avoids repeated tick
counter resets and unnecessary overhead.

3fa7b1055b remoteproc: imx: Add i.MX95 support
i.MX95 uses System Manager(sm) API to start/stop logical machine or cpu.
There are two modes:
 M7 in a dedicated logical machine, use LMM API
 M7 and A55 in same logical machine, use CPU API

Extend the driver to using LMM and CPU protocol to manage the M7 core:
 - Detect using LMM or CPU API in probe using API scmi_imx_lmm_info().
 - Compare linux LM ID(got using scmi_imx_lmm_info) and M7 LM ID(the ID
   is fixed as 1 in SM firmware if M7 is in a separate LM),
   if Linux LM ID is not same as M7 LM ID(linux and M7 in same LM), use
   LMM protocol to start/stop. Whether using CPU or LMM protocol to
   start/stop, the M7 status detection could use CPU protocol to detect
   started or not. So in imx_rproc_is_running, use scmi_imx_cpu_started to
   check the status of M7.
 - For above case (2), Use scmi_imx_lmm_power_boot to detect whether
   the M7 LM is under control of A55 LM.
 - For above case , after using SCMI_IMX_LMM_POWER_ON to check
   permission, scmi_imx_lmm_shutdown API should be called to shutdown
   the M7 LM.
 - Add a new ops imx_rproc_ops_sm.

8beb70f230 net: dwc_eth_qos: Start DMA and MAC after tail pointers are initialized
The DesignWare Cores Ethernet Quality-of-Service databook state that
receive and transmit descriptor list address and also transmit and
receive tail pointer registers should be initialized before the receive
and transmit DMAs are started.

It also state to enable the MAC receiver only after the DMA is active.
Otherwise, received frames can fill the Rx FIFO and overflow.

Move the activation of receive and transmit DMA and MAC receiver until
after tail pointer registers have been initialized.

34c1ab534c net: dwc_eth_qos: Initialize the transmit tail pointer in eqos_start()
The DesignWare Cores Ethernet Quality-of-Service databook state that
descriptors up to one location less than the one indicated by the
descriptor tail pointer are owned by the DMA. The DMA continues to
process the descriptors until the following condition occurs:

  Current Descriptor Pointer == Descriptor Tail Pointer

The DMA goes into suspend mode when this condition occurs, and updating
the tail pointer resume the DMA processing.

Configure the transmit tail pointer to the first (current) descriptor
pointer so that the tail pointer is a valid address instead of being
initialized to NULL when transmit DMA is started.

Also update the receive tail pointer comment to state that by pointing
to the last descriptor we are actually implying that all receive
descriptors are owned by and can be processed by the DMA.

5f0b0ad722 Merge patch series "arm: k3: j722s: add PCIe support"
George McCollister <george.mccollister@konsulko.com> says:

This patch series brings over several changes from Linux that are required
to get PCIe working on the j722s and also enables PCIe in
j722s_evm_a53_defconfig. This allows Linux to be booted from an NVMe drive.

The J722S SoC provides pcie0 (using pcie_cdns_ti) thru serdes1
(using phy-cadence-torrent) thru serdes_wiz1 (using phy-j721e-wiz). Changes
to the three drivers needed to be ported from Linux to enable the REFCLK
output which is used with this SoC. These changes should be tested on other
platforms using these drivers by those with the hardware available to make
sure no problems were introduced.

The PCIe controller in this SoC relies on the code performing the PCI scan
not scanning devices which cannot exist. In Linux this is implemented as
only_one_child() in probe.c. If this mechanism is not used, PCI config reads
for subsequent functions will return information for device 0 resulting in
U-Boot detecting 32 devices when only 1 is present. This change should be
tested on other platforms with PCI to ensure the same PCI devices are
enumerated before and after the patch is applied.

I would like to thank Opto 22 for sponsoring the initial development and
anyone that is able to contribute to testing of patches.
