Hello,
This patch series adds support for scaling and rotation to the VSP1 driver on

There are pins on the Salvator-X which is not part of a GPIO bank nor
can be muxed between different functions. They do however allow for the
drive-strength to be configured. Add those pins to the list of pins and
to the drive-strength configuration registers.
The pins can now be referred to in DT
Group the QSPI0 and QSPI1 pins into similar groups found in other sh-pfc

Pins not associated with a GPIO port can still have other configuration
parameters. Add a new macro SH_PFC_PIN_NAMED_CFG which allows for named
pins to be declared with a set of configurations. The new macro is an
