Device tree bindings for ARM PL353 static memory controller
PL353 static memory controller supports two kinds of memory
interfaces.i.e NAND and SRAM/NOR interfaces.
The actual devices are instantiated from the child nodes of pl353 smc node.
Required properties:
- compatible : Should be "arm,pl353-smc-r2p1", "arm,primecell".
- reg : Controller registers map and length.
- clock-names : List of input clock names - "memclk", "apb_pclk"
(See clock bindings for details).
- clocks : Clock phandles (see clock bindings for details).
- address-cells : Must be 2.
- size-cells : Must be 1.
Child nodes:
For NAND the "arm,pl353-nand-r2p1" and for NOR the "cfi-flash" drivers are
supported as child nodes.
for NAND partition information please refer the below file

* Implementation of the SCU based Power Domains
*
* NOTE: a better implementation suggested by Ulf Hansson is using a
* single global power domain and implement the ->attach|detach_dev()
* callback for the genpd and use the regular of_genpd_add_provider_simple().
* From within the ->attach_dev(), we could get the OF node for
* the device that is being attached and then parse the power-domain
* cell containing the "resource id" and store that in the per device
* struct generic_pm_domain_data (we have void pointer there for
* storing these kind of things).
*
* Additionally, we need to implement the ->stop() and ->start()
* callbacks of genpd, which is where you "power on/off" devices,
* rather than using the above ->power_on|off() callbacks.
*
* However, there're two known issues:
* 1. The ->attach_dev() of power domain infrastructure still does
* not support multi domains case as the struct device *dev passed
* in is a virtual PD device, it does not help for parsing the real
* device resource id from device tree, so it's unware of which
* real sub power domain of device should be attached.
*
* The framework needs some proper extension to support multi power
* domain cases.
*
* 2. It also breaks most of current drivers as the driver probe sequence
* behavior changed if removing ->power_on|off() callback and use
* ->start() and ->stop() instead. genpd_dev_pm_attach will only power
* up the domain and attach device, but will not call .start() which
* relies on device runtime pm. That means the device power is still
* not up before running driver probe function. For SCU enabled
* platforms, all device drivers accessing registers/clock without power
* domain enabled will trigger a HW access error. That means we need fix
* most drivers probe sequence with proper runtime pm.
*
* In summary, we need fix above two issue before being able to switch to
* the "single global power domain" way.
