This is accomplished by introducing a new ti-emif-sram-pm call, ti_emif_run_hw_leveling, to check if DDR3 is in use and if so, trigger the full write and read leveling processes.

2018-08-27memory: atmel-ebi: Use struct_size() in devm_kzalloc()Gustavo A. R. Silva
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.

The Reset Controller should be registered in the end of probe, otherwise Memory Controller device goes away if IRQ requesting fails and the Reset Controller stays registered. To avoid having to unwind the MC probing in a case of SMMU probe failure, let's simply print the error message without failing the MC probe. This allows us to just move the Reset Controller registering before the SMMU registration, reducing code churning. Also let's not fail MC probe in a case of Reset Controller registration failure as it doesn't prevent the MC driver to work.
