The Rock 5 ITX only needs enablement for 2 nodes in order to send audio
on HDMI1, the connector closer to the 12V barrel jack and farther from
S/PDIF. It is sufficient to declare the audio injection as okay, and
to activate I2S6.
Note that for the other HDMI output it is not that trivial, as the video
data there originates from the SoC's DisplayPort output DP1 and is only
converted to HDMI in U7 (an RA620).

Due to the discussion about cd-gpios and sdmmmc_det pin functionality [1],
it would be better to use cd-gpios for now.
When the sdmmc controller runtime-suspends, the detection logic inside the
controller cannot detect anything anymore, which using the gpio variant
fixes.
The Rock 5B/5B+/5T already uses cd-gpios, so only get the pinctrl added.

The Radxa ROCK 5B+/5T USB Type-C port supports Dual Role Data and
should also act as a host. However, currently, when acting as a host,
only self-powered devices work.
Since the ROCK 5B+ supports Dual Role Power, set the power-role
property to "dual" and the try-power-role property to "sink". (along
with related properties)
The ROCK 5T should only support the "source" power-role.
This allows the port to act as a host, supply power to the port, and
allow bus-powered devices to work.
Note that on the ROCK 5T, with this patch applied, it has been
observed that some bus-powered devices do not work correctly. Also,
it has been observed that after connecting a device (and the data-role
switches to host), connecting a host device does not switch the
data-role back to the device role. These issues should be addressed
separately.
Note that there is a separate known issue where USB 3.0 SuperSpeed
devices do not work when oriented in reverse. This issue should also be
addressed separately. (USB 2.0/1.1 devices work in both orientations)

When the device was first added, there was a problem with the bluetooth
controller that manifested when DMA was enabled for the underlying UART
interface. At some point in the intervening time the problem appears to
have been resolved. Add the UART rx and tx channels back to re-enable
UART.

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().
