Hi All,
Here is v6 of my patch-series for dealing with multiple independent i2c
devices being described in a single ACPI fwnode.
Changes in v6:
-Added some Reviewed-by and Acked-by-s to patches 2-4
-4th patch "platform/x86: Add ACPI i2c-multi-instantiate pseudo driver":
-s/irq_idx/gpio_irq_idx/
On systems with ACPI instantiated i2c-clients, normally there is 1 fw_node
per i2c-device and that fw-node contains 1 I2cSerialBus resource for that 1
i2c-device.
But in some rare cases the manufacturer has decided to describe multiple
i2c-devices in a single ACPI fwnode with multiple
Now that we init the status field to ACPI_STA_DEFAULT rather then to 0,
the workaround for acpi_match_device_ids() always returning -ENOENT when
status is 0 is no longer needed.

Since commit 63347db0affa ("ACPI / scan: Use acpi_bus_get_status() to
initialize ACPI_TYPE_DEVICE devs") the status field of normal acpi_devices
gets set to 0 by acpi_bus_type_and_status() and filled with its actual
value later when acpi_add_single_object() calls acpi_bus_get_status().

When we failed to modify breakpoint, we ended up with
disabled event. Mirror that in its 'attr.disabled',
because some parts of the ptrace code depends on it.

Once the breakpoint was succesfully modified, the attr->disabled
value is in bp->attr.disabled. So there's no reason to set it
again, removing that.

This is another series of tsens cleanups before we add interrupt support.
This applies on top of the earlier two series[1][2] that have already been
accepted for 4.19.
In this series, we have the following:

Always update the stopped state when busy status have been checked.
This is identical to what was done before, with the exception of error
handling.
Without this change, some errors cause the stopped state to be left in
incorrect state in i2c_imx_stop(), i2c_imx_dma_read(),

This fixes a race condition, where the DMAEN bit ends up being set after
I2C slave has transmitted a byte following the dummy read. When that
happens, an interrupt is generated instead, and no DMA request is generated
to kickstart the DMA read, and a timeout happens after

The SCCG is a new PLL type introduced on i.MX8. Add support for this.
The driver currently misses the PLL lock check, as the preliminary
documentation mentions lock configurations, but is quiet about where
to find the actual lock status signal.

This is basically just a resend of the following patchset:

I've just updated the patchset and implemented Shawn's
and Aisheng's comments.
I hope I haven't missed any of their comments.

The name 'samples*' is little confusing because we have nested 'struct
sym_hist_entry' under annotation_line struct, which holds 'nr_samples'
as well.
Also the holding struct name is 'annotation_data' so the 'data' name
fits better.

bitmap_zero() is called after bitmap_alloc() in perf code. But
bitmap_alloc() internally uses calloc() which guarantees that allocated
area is zeroed. So following bitmap_zero is unneeded. Drop it.
This happened because of confusing name for bitmap allocator. It

As per Figure 6-3 in PCIe r4.0, sec 6.2.6, ERR_ messages
will be forwarded from the secondary interface to the primary interface,
if the SERR# Enable bit in the Bridge Control register is set.
Currently PCI_BRIDGE_CTL_SERR is being enabled only in
ACPI flow.

If threshold_init_device() fails then per_cpu(threshold_banks) will be
deallocated. The thresholding interrupt handler will still be active, so
it's possible to get a NULL pointer dereference if a THR interrupt
happens and any of the structures are NULL.
