This commit adds the necessary device-properties to make the touchscreen
on Point of View mobii TAB-P800W (v2.0) tablets work.
Note that we already have an entry for the Point of View mobii
TAB-P800W (v2.1), that version uses a different digitizer and different
firmware, so the v2.0 version needs its own entry.

The comparison with the number of elements in array df_v3_7_channel_number

If the namespace is unregistered before the LightNVM target is removed
(e.g., on hot unplug) it is too late for the target to store any metadata
on the device - any attempt to write to the device will fail. In this
case, pass on a "gracefull teardown" flag to the target to let it know
when this happens.
In the case of pblk, we pad the open line (close all open chunks) to

Per section 5.2 we need to issue the corresponding log page to clear an
AEN, so for a namespace data changed AEN we need to read the changed
namespace list log. And once we read that log anyway we might as well

Some Renesas controllers get into a weird state if they are reset while
programmed with 64bit addresses (they will preserve the top half of the
address in internal, non visible registers).
You end up with half the address coming from the kernel, and the other
half coming from the firmware.
Also, changing the programming leads to extra accesses even if the
controller is supposed to be halted. The controller ends up with a fatal
fault, and is then ripe for being properly reset. On the flip side,
this is completely unsafe if the defvice isn't behind an IOMMU, so
we have to make sure that this is the case. Can you say "broken"?
This is an alternative method to the one introduced in 8466489ef5ba
("xhci: Reset Renesas uPD72020x USB controller for 32-bit DMA issue"),
which will subsequently be removed.

BIT macro is being used to get mask for gpio's pin
which is retrieved using 'hwirq' from struct irq_data.
The problem here is that 'hwirq' can be as large as 95,
and 1UL << 95 is unlikely to work well. Instead of using
BIT macro use a new PIN_MASK macro which takes into account
pin and WIDTH of the bank in order to make a proper mask for
the gpio pin. Also 'd->hwirq' has been replaced by 'pin' in
some places because there was a 'pin' variable in changed
functions with the proper value. This improves readability.

The driver's init function don't do anything besides registering the platform
driver, and the exit function which is not included in the driver should only
do driver unregister. Because of this module_platform_driver() macro could
just be used instead of having separate functions.
Currently the macro is not being used because the driver is initialized at
subsys init call level but this isn't necessary since platform devices are
defined in the DT as dependencies so there's no need for init calls order.
