This patch-set handles the SPI/I2S IP on STM32 platforms.
It applies to STM32 platforms implementing version 2 of SPI/I2S IP like STM32H7
series.
The SPI/I2S block is a serial peripheral interface (SPI), which can also be
configured to work on I2S/PCM mode.
ASoC STM32 I2S driver only supports t
This patch allows to use i2s interface either as single
audio path (rx or tx), or bidirectional audio path.
This patch is added separately, as the driver does not
follow recommended use of the interface, to support this
configuration.

Kernel falls back to non SMP mode and sets up interrupt delivery mode

Setting up interrupt delivery mode as soon as possible should wraps

Currently, enable and setup the interrupt mode has been advanced
just behind the timer IRQ setup. It can setup the virtual wire

The apic_virtual_wire_mode_setup() which works for the virtual wire

The apic_bsp_setup() set up the local APIC, I/O APIC and APIC timer.

This is an RFC as I didn't run any benchmarks. It just seemed a bit

data points to an unsigned long. So while this works on LE machines this is

Vhost-vsock is a software device so there is no probe call that causes
the driver to register its misc char device node. This creates a
chicken and egg problem: userspace applications must open
/dev/vhost-vsock to use the driver but the file doesn't exist until the
kernel module has been loaded.

The driver currently uses "apid" and "chan" to mean apid. Remove
the use of chan and use only apid.
On a SPMI bus there is allocation to manage up to 4K peripherals.
However, in practice only few peripherals are instantiated
and only few among the instantiated ones a
From: Abhijeet Dharmapurikar
The current driver uses a mix of radix tree and a fwd lookup
table to translate between apid and ppid. It is buggy and confusing.
Instead simply use a radix tree for v1 hardware and use the
forward lookup table for v2.

We see a unmapped irqs trigger right around bootup. This could

The driver currently invokes the apid handler (periph_handler())
once it sees that the summary status bit for that apid is set.
However the hardware is designed to set that bit even if the apid
