Being able to validate bindings has been discussed for years with little progress. - Initial support for DT bindings using json-schema language.

2018-08-28memory: atmel-ebi: Use struct_size() in devm_kzalloc()Gustavo A. R. Silva1-2/+1
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.

2018-06-13treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook1-2/+2
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

We can hook sysfs objects to the parent platform device that we are created from, no need to have a synthetic dpfe_dev just for that. This incidentally removes the need for having an index, since we are guaranteed to have an unique path in the sysfs hiearchy.

2018-04-30memory: tegra: Squash tegra20-mc into common tegra-mc driverDmitry Osipenko7-277/+290
Tegra30+ has some minor differences in registers / bits layout compared to Tegra20. Let's squash Tegra20 driver into the common tegra-mc driver in a preparation for the upcoming MC hot reset controls implementation, avoiding code duplication. Note that this currently doesn't report the value of MC_GART_ERROR_REQ because it is located within the GART register area and cannot be safely accessed from the MC driver (this happens to work only by accident). The proper solution is to integrate the GART driver with the MC driver, much like is done for the Tegra SMMU, but that is an invasive change and will be part of a separate patch series.

Currently aemif is supported in two places separately. By the platform driver in drivers/memory and by a hand crafted driver in mach-davinci. We want to drop the latter but also keep the legacy mode. Add support for board files to the aemif driver. The new structure in platform data currently only contains the chip select number, since currently existing users don't require anything else, but it can be extended in the future. While extending the platform data struct, add kernel docs describing its members.
