spi: docs: adjust summary to CONFIG_SYSFS_DEPRECATED removal 2023-03-14T13:30:52+00:00 Lukas Bulwahn lukas.bulwahn@gmail.com 2023-03-14T07:56:09+00:00 93d205457dcda137e73dbfdcaa6a3c4c3b6d505f With commit 721da5cee9d4 ("driver core: remove CONFIG_SYSFS_DEPRECATED and CONFIG_SYSFS_DEPRECATED_V2"), ./scripts/checkkconfigsymbols.py indicated an unresolved reference to the config SYSFS_DEPRECATED in the SPI summary documentation. Simply, delete the sentence referring to the removed config there. Also update the documentation, as these sys/class entries should always be symlinks, as the commit message of the commit above suggests.

The device tree and ACPI paths of the driver already use descriptors, hence ->use_gpio_descriptors is already set and this codepath is well tested. Convert all the PXA boards providing chip select GPIOs as platform data and drop the old GPIO chipselect handling in favor of the core managing it exclusively.
