Miaoqing Pan ed14dc0af7 ath9k: feeding entropy in kernel from ADC capture ... This patch is derived from commit 6301566e0b ("ath9k: export HW random number generator"), We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x, and AR9340, and it has sufficient quality random data (at least 10 bits and up to 22 bits of min-entropy for a 32-bit value). We conservatively assume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZE is set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill up the pool as soon as the entropy counter becomes 896/4096 (set by random.c). Since ADC was not designed to be a dedicated HW RNG, we do not want to bind it to /dev/hwrng framework directly. This patch feeds the entropy directly from the WiFi driver to the input pool. The ADC register output is only used as a seed for the Linux entropy pool. No conditioning is needed, since all the conditioning is performed by the pool itself.
