This reverts commit 39e4189d9d.
The board uses SDHC VSELECT to automatically switch between 1.8v and
3.3v. It does not use GPIO to control the PMIC SD_VSEL signal.
The original commit intends to read back SD_VSEL value from GPIO,
but it is wrong. When MUX is configured as SDHC VSELECT, it is
impossible to read back the value from GPIO controller. Setting SION
could only enable the input path for the mux function. It could not
redirect the input to GPIO.

On the Toradex SMARC iMX95, the WiFi UART signals are shared with the
JTAG. The WIFI_UART_EN signal is used to select between these
two functions. A GPIO hog is used to select the UART function by
default. This DT file is going to be used by both Linux and the boot
firmware, and the boot firmware will configure the GPIO hog way before
the Linux kernel is booted, therefore there is no actual race condition
between the Linux kernel BT UART driver and GPIO hog probe.

When processor_thermal_soc_slider is loaded, its slider
and offset modparams are visible. Check that the driver
actually registered the profile named "SoC Slider" before
reading or writing these modparams.

even if the driver policy is not "balanced". Currently the

Pull ring-buffer fix from Steven Rostedt:
- Fix accounting of persistent ring buffer rewind
On boot up, the head page is moved back to the earliest point of the
saved ring buffer. This is because the ring buffer being read by user
space on a crash may not save the part it read. Rewinding the head
page back to the earliest saved position helps keep those events from
being lost.
The number of events is also read during boot up and displayed in the
stats file in the tracefs directory. It's also used for other
accounting as well. On boot up, the "reader page" is accounted for
but a rewind may put it back into the buffer and then the reader page
may be accounted for again.
Save off the original reader page and skip accounting it when
scanning the pages in the ring buffer.
