memory: atmel-ebi: Use of_property_present() for testing DT property presence

2023-03-13T06:53:45+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

memory: atmel-ebi: Fix missing of_node_put in atmel_ebi_probe

2022-04-04T16:29:33+00:00

The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done.

memory: atmel-ebi: add missing of_node_put for loop iteration

2021-05-11T12:49:18+00:00

Early exits from for_each_available_child_of_node() should decrement the node reference counter. Reported by Coccinelle: drivers/memory/atmel-ebi.c:593:1-33: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before return around line 604.

memory: atmel-ebi: Use struct_size() in devm_kzalloc()

2018-08-27T21:10:31+00:00

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This issue was detected with the help of Coccinelle.

mfd: syscon: atmel-smc: Add helper to retrieve register layout

2017-09-05T07:46:01+00:00

For HSMC controller, the register layout depends on the device i.e. the offset of setup, pulse, cycle, mode and timings registers is not the same. An helper is added to provide the correct register layout.
