[PATCH 0/3] Add support for secure regions in Qcom NANDc driver

On a typical end product, a vendor may choose to secure some regions in
the NAND memory which are supposed to stay intact between FW upgrades.
The access to those regions will be blocked by a secure element like
Trustzone. So the normal world software like Linux kernel should not
touch these regions (including reading).

So this series adds a property for declaring such secure regions in DT
so that the driver can skip touching them. While at it, the DT binding
is also converted to YAML format.

Thanks,
Mani
