Currently, HDMI audio cannot play sound at a 44.1 kHz sample rate due to
a clock frequency mismatch. This update resolves the issue by allowing
the sai driver to change the clock parent to AUDIO_PLL_1 when the sample
rate is 44.1 kHz. It also ensures that AUDIO_PLL_1 operates at the
correct frequency for this configuration.

The HDMI DDC pads can be muxed either to an i.MX I2C controller or
to a limited I2C controller within the Designware HDMI bridge.
So far, the pads were muxed to the HDMI bridge, but the i.MX I2C controller
is the better choice:
- The Designware HDMI I2C controller doesn't support multi-byte
requests and the Linux driver refuses[1] transfers to/from address
0x37, but these are required for display/brightness configuration,
- The driver doesn't support I2C bus recovery, but some HDMI panels used
with the board can be flaky and require it.
As the i.MX I2C controller and driver don't have either of these
limitations, let's make use of it instead.

The PMIC voltage constraints in the device tree currently describe the
permissible range of the PMIC. This is unnecessary as this information
already exists in the driver and wrong as it doesn't account for
board-specific constraints, e.g. a 2.1V on VDD_SOC would fry the SoC and
a maximum voltage of 3.4V on the VDD_3V3 rail may be unexpected across
the board.
Fix this by adjusting constraints to reflect the board limits.

This fixes the LDO5 regulator handling of the pca9450 driver by
taking the status of the SD_VSEL into account to determine which
configuration register is used for the voltage setting.
Even without this change there is no functional issue, as the code
for switching the voltage in sdhci.c currently switches both, the
VSELECT/SD_VSEL signal and the regulator voltage at the same time
and doesn't run into an invalid corner case.
We should still make sure, that we always use the correct register
when controlling the regulator. At least in U-Boot this fixes an
actual bug where the wrong IO voltage is used and it makes sure
that the correct voltage can be read from sysfs.

Currently, the scsi_debug driver can create tape devices and the st
driver attaches to those. Nothing much can be done with the tape devices
because scsi_debug does not have support for the tape-specific commands
and features. These patches add some more tape support to the scsi_debug
driver. The end result is simulated drives with a tape having one or two
partitions (one partition is created initially).
The tape is implemented as fixed number (10 000) of 8-byte units.
The first four bytes of a unit contain the type of the unit (data
block, filemark or end-of-data mark). If the units is a data block,
the first four bytes also contain the block length and the remaining
four bytes the first bytes of written data. This allows the user
to use tags to see that the read block is what it was supposed to be.
The following SCSI operations are added or modified:
FORMAT MEDIUM
- added
LOCATE
- added
MODE SELECT
- modified to allow use without page(s) (just header and block descriptor)
- store density and block size
- partition page added

- partition page added

The PCI P2PDMA code will register the CMB block to the memory
hot-plugging subsystem, which have an alignment requirement. Memory
blocks that do not satisfy this alignment requirement (usually 2MB) will
lead to a WARNING from memory hotplugging.
Verify the CMB block's address and size against the alignment and only
try to send CMB blocks compatible with it to prevent this warning.
Tested on Intel DC D4502 SSD, which has a 512K CMB block that is too
small for memory hotplugging (thus PCI P2PDMA).

Currently CONFIG_PWM is a bool but I intend to change it to tristate. If
CONFIG_PWM=m in the configuration, the cpp symbol CONFIG_PWM isn't
defined and so the PWM code paths in the ti-sn65dsi86 driver are not
used.
The correct way to check for CONFIG_PWM is using IS_REACHABLE which does
the right thing for all cases
CONFIG_DRM_TI_SN65DSI86 ∈ { y, m } x CONFIG_PWM ∈ { y, m, n }.
There is no change until CONFIG_PWM actually becomes tristate.
