Hello.
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 (requires
https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git/commit/?id=cdd745c8c76b02471d88f467c44a3d4eb431aa0b).
Changes in v3:
- Changed node-name in device-tree bindings according to from Krzysztof
Koz³owski's recommendation.
- Fixed name and added EXYNOS_ in EXYNOS_TRNG_CTRL_RNGEN
- Removed unnecessary label and simplifed the abnormal exit path in
exynos_trng_probe()
- Replaced __raw_{readl,writel}() with {readl,writel}_relaxed() (thanks
PrasannaKumar Muralidharan)
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().
