AHUB driver misses D_AUDIO and APBIF resets. CPU hangs on trying to
access hardware if resets aren't de-asserted. This problem is currently
masked by the tegra-clk driver which implicitly de-asserts the resets when
the corresponding clocks are enabled. Soon the implicit de-assertion will
be gone

This series improves the handling of clock and reset controls of
NVIDA Tegra ALSA drivers. Tegra HDA and AHUB drivers aren't handling
resets properly, which needs to be fixed in order to unblock other patches
related to fixes of the reset controller driver since HDA/AHUB are bound
to fail once
The "chip" can't be NULL in hda_tegra_runtime_resume() because code would
crash otherwise. Let's remove the unnecessary check in order to clean up
code a tad.

The RPi4 has an Arasan controller it carries over
from the RPi3 and a newer eMMC2 controller.
Because of a couple of quirks, it seems wiser to bind
these controllers to the same driver that DT is using
on this platform rather than the generic sdhci_acpi
driver with PNP0D40.
So, BCM2847 describes
The rpi4 can be booted on Linux using ACPI, this set
adds the ACPI bindings to allow it to utilize the Arasan
and eMMC2 controllers.

An enabled user-specified exception event that does not clear quickly will
repeatedly cause the handler to run. That could unduly disturb the driver

This patch allows statistics to be enabled for each DMA-BUF in
sysfs by enabling the config CONFIG_DMABUF_SYSFS_STATS.
The following stats will be exposed by the interface:
/sys/kernel/dmabuf/buffers//exporter_name
/sys/kernel/dmabuf/buffers//size
/sys/kernel/dmabuf/buffers//attachments//device
