* hwrng: mxc-rnga - add driver support on boards with device treeVladimir Zapolskiy2018-03-161-9/+14
| | | | | | | | | | | | The driver works well on i.MX31 powered boards with device description taken from board device tree, the only change to add to the driver is the missing OF device id, the affected list of included headers and indentation in platform driver struct are beautified a little.

* hwrng: mxc-rnga - Access data via structureFabio Estevam2012-09-061-57/+51
| | | | | | | | | | | | In current driver, everytime we need to access the rng clock ,ie to enable or disable it, a call to clk_get is done. This is not correct and the preferred way is to provide a rng data structure that could be used for accessing rng resources.
