Add support for the Toradex Aquila AM69 and its Development Carrier
Board.
The Aquila AM69 SoM is based on the TI AM69 SoC from the Jacinto 7
family and is designed for high-end embedded computing, featuring up to
32GB of LPDDR4 and 256GB eMMC storage, extensive multimedia support (3x
Quad CSI, 2x Quad DSI, DisplayPort, 5x Audio I2S/TDM), six Ethernet
interfaces (1x 1G, 4x 2.5G SGMII, 1x 10G), USB 3.2 Host/DRD support, and
a Wi-Fi 7/BT 5.3 module, alongside an RX8130 RTC, I2C EEPROM and
Temperature Sensor, and optional TPM 2.0 module.
Various nodes, inherited from the SoC dtsi, are explicitly disabled in
the SoM dtsi file (`status = disabled`) even if already disabled. These
nodes need to be disabled in the SoM, given that the node is not
complete there, explicitly disabling it limits the dependency on the SoC
dtsi allowing for refactoring without no impact on this file.

The MAC Ports across all of the CPSW instances (CPSW2G, CPSW3G, CPSW5G and
CPSW9G) present in various K3 SoCs only support the 'RGMII-ID' mode. This

a) Device-Tree binding for CPSW [0]
b) Driver for CPSW [1]
c) Driver for CPSW MAC Port's GMII [2]

do not support internal pull-ups [0][1][2]. The pullup configuration
bits in the corresponding padconfig registers are reserved and any

At the moment the clock parent of the audio extclk output is PLL1_HSDIV6
of the main domain. This very clock output is also used among various IP
cores, for example for the USB1 LPM clock. The audio extclock being an
external clock output with a variable frequency, it is likely that a
user of this clock will try to set it's frequency to a different value,
i.e. an audio codec. Because that clock output is used also for other IP
cores, bad things will happen.
Instead of using PLL1_HSDIV6 use the PLL2_HSDIV8 as a sane default, as
this output is exclusively used among other audio peripherals.

irqchip/sifive-plic: Avoid interrupt ID 0 handling during suspend/resume
irqchip/aspeed-scu-ic: Fix an IS_ERR() vs NULL check
The previous fix to trace_marker required updating trace_marker_raw
as well. The difference between trace_marker_raw from trace_marker
is that the raw version is for applications to write binary structures
directly into the ring buffer instead of writing ASCII strings.
This is for applications that will read the raw data from the ring
buffer and get the data structures directly. It's a bit quicker than
using the ASCII version.
Unfortunately, it appears that our test suite has several tests that
test writes to the trace_marker file, but lacks any tests to the
trace_marker_raw file (this needs to be remedied). Two issues came
about the update to the trace_marker_raw file that syzbot found:
- Fix tracing_mark_raw_write() to use per CPU buffer
The fix to use the per CPU buffer to copy from user space was needed for
both the trace_maker and trace_maker_raw file.
The fix for reading from user space into per CPU buffers properly fixed
the trace_marker write function, but the trace_marker_raw file wasn't
fixed properly. The user space data was correctly written into the per CPU
buffer, but the code that wrote into the ring buffer still used the user
space pointer and not the per CPU buffer that had the user space data
already written.
- Stop the fortify string warning from writing into trace_marker_raw
After converting the copy_from_user_nofault() into a memcpy(), another
issue appeared. As writes to the trace_marker_raw expects binary data, the
first entry is a 4 byte identifier. The entry structure is defined as:
struct {
struct trace_entry ent;
int id;
char buf[];
};
The size of this structure is reserved on the ring buffer with:
size = sizeof(*entry) + cnt;
Then it is copied from the buffer into the ring buffer with:
memcpy(&entry->id, buf, cnt);
This use to be a copy_from_user_nofault(), but now converting it to
a memcpy() triggers the fortify-string code, and causes a warning.
The allocated space is actually more than what is copied, as the cnt
used also includes the entry->id portion. Allocating sizeof(*entry)
plus cnt is actually allocating 4 bytes more than what is needed.
Change the size function to:
size = struct_size(entry, buf, cnt - sizeof(entry->id));
And update the memcpy() to unsafe_memcpy().

further testing to be causing data corruption.
