Tomasz Bursztyka	e18fcbba5a	device: Const-ify all device driver instance pointers ... Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>	2020-09-02 13:48:13 +02:00
Peter Bigot	7a8a4c9b3e	drivers: spi: document expectation on spi config parameter ... Most if not all drivers use an internal function spi_context_configured() to bypass reconfiguring the SPI peripheral when nothing has changed. That function determines change based on comparing the struct spi_config pointer that was last used. This does not work if a user changes fields within the pointed-to structure. Document that pointer comparison may be used to detect changes. Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>	2020-08-26 12:25:06 +02:00

Jordan Yates	5963ebaf33	drivers: spi: CS configuration through devicetree ... Add an additional option to the spi_cs_control struct that records how the pin has been configured in devicetree. For drivers that are not updated, the CS behaviour is the same as before (Push-Pull). Use the devicetree knowledge with the GPIO subsystem so that the correct physical pin levels for the CS pin are automatically selected.

Corey Wharton	86bfc489f4	scripts: Replace hard-coded subsystem list with __subsystem annotations. ... This change removes the hardcoded subsystem list in gen_kobject_list.py favor of marking the relevant driver API structs with the _subsystem sentinel.
