The following patches add support for the true random number generator found in Samsung Exynos 5250+ SoCs. Patch #1 adds documentation for devicetree bindings. Patch #2 introduces the driver and appropriate changes in Makefile and Kconfig. Patch #3 adds nodes in devicetree files for Exynos SoCs. Changes in v2: - Fixed indentation in drivers/char/hw_random/Kconfig. - Defined TRNG_CTRL_RGNEN. - Removed global variable exynos_trng_dev. - Removed exynos_trng_{set,get}_reg() functions. - Used the min_t() macro instead of the ternary operator in exynos_trng_do_read(). - Moved trng initialisation to the variable declaration in exynos_trng_init(). - Fixed comment formating. - Removed unnecessary "TODO" comments. - Return ENOMEM, if devm_kzalloc() devm_kstrdup() fail. - Rephrased and unified error messages in exynos_trng_probe(). - Removed nullification of trng->mem. - Added err_pm_get label at the end of exynos_trng_probe(). - Removed double error message at the end of exynos_trng_probe(). - Implemented exynos_trng_remove().
