| Series | [OpenWrt-Devel] ath9k: allow enabling hardware random number generator support. | expand |
Please ignore this patch too. I'm going to send a more complete one (against master), implementing ath9k-rng support for both AR5008 and AR9002 (in addition to the already supported AR9003).

Changes since RFC: keep the current entropy patch untouched. It will be modified in order to support older (AR5008 and AR9002) hardware. The ath9k driver is able to leverage the PHY ADC in order to provide a generic hardware random number generator to the kernel, filling up the entropy pool as required. Expose this feature in the build system.
