Gerard Marull-Paretas	a5fd0d184a	init: remove the need for a dummy device pointer in SYS_INIT functions The init infrastructure, found in `init.h`, is currently used by: - `SYS_INIT`: to call functions before `main` - `DEVICE_`: to initialize devices They are all sorted according to an initialization level + a priority. `SYS_INIT` calls are really orthogonal to devices, however, the required function signature requires a `const struct device dev` as a first argument. The only reason for that is because the same init machinery is used by devices, so we have something like: ```c struct init_entry { int (init)(const struct device dev); /* only set by DEVICE_, otherwise NULL / const struct device dev; } ``` As a result, we end up with such weird/ugly pattern: ```c static int my_init(const struct device dev) { /* always NULL! add ARG_UNUSED to avoid compiler warning / ARG_UNUSED(dev); ... } ``` This is really a result of poor internals isolation. This patch proposes a to make init entries more flexible so that they can accept sytem initialization calls like this: ```c static int my_init(void) { ... } ``` This is achieved using a union: ```c union init_function { / for SYS_INIT, used when init_entry.dev == NULL / int (sys)(void); /* for DEVICE, used when init_entry.dev != NULL / int (dev)(const struct device dev); }; struct init_entry { /* stores init function (either for SYS_INIT or DEVICE) union init_function init_fn; / stores device pointer for DEVICE, NULL for SYS_INIT. Allows to know which union entry to call. / const struct device dev; } ``` This solution does not increase ROM usage, and allows to offer clean public APIs for both SYS_INIT and DEVICE. Note that however, init machinery keeps a coupling with devices. NOTE: This is a breaking change! All `SYS_INIT` functions will need to be converted to the new signature.

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>	5 years ago

Aurelien Jarno	bf59fcb78c	drivers: hwinfo: add driver support for Atmel SAM device ID Add driver support for Atmel SAM device ID, which is 16-bytes long. On this SoC family, the device ID is part of the flash controller and complex to read. Therefore the driver reads it once at boot time and then just returned the copy saved in RAM.
