A previous refactoring moved the chip select number handling
to the SPI core and we missed a leftover platform data user
in the ST spear platform. The spear is not using this
chipselect or PL022 for anything and should be using device
tree like the rest of the platform so just delete the
offending platform data.

Hi,

This series picks up Ramuthevar's effort on converting the Cadence QSPI
bindings to yaml [0]. During the conversion process, I discovered that
some TI device tree files were not using the compatible correctly. Those
are fixed in patches 1-3.

There is no way as of now to have a parent or bus defining properties
for child nodes. For now, avoid it in the example to silence warnings on
dt_schema_check. We can figure out how to deal with actual dts files
later.

This converts the PL022 driver to use GPIO descriptors
instead of the old global GPIO numberspace. Since the
driver handles messages on its own it needs to manage
the GPIO descriptor directly.

The SPI core looks up GPIO lines from the device tree,
so let's stop trying to do that on our own and rely
on the core to do this for us.

In addition to the GPIO line we also need to keep
track of the chip select index separately, as the native
chip select needs this index. The driver was reusing
the same GPIO array for native chip select indices,
so keep this in a separate state variable instead.

The facility to pass in custom GPIO lines from the
platform data can go, because even if we do have
out-of-tree code that want to use platform data, they
can soon pass in GPIOs using machine GPIO descriptor
tables which will be available after the next step
when we convert the driver to using GPIO descriptors.

The implicit inclusion of <linux/of.h> is made
explicit as we no longer need to include <linux/of_gpio.h>.

When using the device tree, which must be considered normal
these days, in order to get some kind of normal functionality
out of the PL022 users have to actively go into the device
tree and edit the SPI clients like this:

spi {
  compatible = "arm,pl022";
  num-cs = <1>;
  cs-gpios = <&gpio 0 GPIO_ACTIVE_LOW>;

  foo@0 {
    compatible = "foo";
    reg = <0>;
    pl022,interface = <0>;
    pl022,com-mode = <0>;
  };
};

Otherwise the PL022 will come up as a client (slave) and
using polling mode. This is quite unintuitive and many users
will get their device trees wrong.

Alter the defaults such that we come up in host mode
(master) and use interrupt mode.

stm32_spi_remove() accesses the driver's private data after calling
spi_unregister_master() even though that function releases the last
reference on the spi_master and thereby frees the private data.

Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound.

Merge series "spi: Adding support for software nodes" from Heikki Krogerus <heikki.krogerus@linux.intel.com>:

Hi,

The older API used to supply additional device properties for the
devices - so mainly the function device_add_properties() - is going to
be removed. The reason why the API will be removed is because it gives
false impression that the properties are assigned directly to the
devices, which has actually never been the case - the properties have
always been assigned to a software fwnode which was then just directly
linked with the device when the old API was used. By only accepting
device properties instead of complete software nodes, the subsystems
remove any change of taking advantage of the other features the
software nodes have.

The change that is required from the spi subsystem and the drivers is
trivial. Basically only the "properties" member in struct
spi_board_info, which was a pointer to struct property_entry, is
replaced with a pointer to a complete software node.

thanks,

Merge series "spi: finalize 'delay_usecs' removal/transition" from Alexandru Ardelean <aardelean@deviqon.com>:

A while back I started the introduction of the 'spi_delay' data type:
  https://lore.kernel.org/linux-spi/20190926105147.7839-1-alexandru.ardelean@analog.com/

Users of the 'delay_usecs' were removed from drivers.

Now it's time to remove the 'delay_usecs' from the SPI subsystem and use
only the 'delay' field.

This changeset adapts all SPI drivers to do without 'delay_usecs'.
Additionally, for greybus we need to adapt it to use the 'delay' in
nano-seconds and convert it to micro-seconds.
