From 4535edbd4214ce21328655434c0b75da404e29b7 Mon Sep 17 00:00:00 2001 From: Raja Mani Date: Thu, 20 Aug 2015 10:29:05 +0530 Subject: [PATCH] ath10k: add spectral scan support for 10.4 fw To enable/configure spectral scan parameters in 10.4 firmware, existing wmi spectral related functions can be reused. Link those functions in 10.4 wmi ops table. In addition, adjust bin size (only when size is 68 bytes) before reporting bin samples to user space. The background for this adjustment is that qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte carries band edge detection data (+32) mainly used in radar detection purpose. Additional last 4 bytes are stripped to make bin size valid one. This bin size adjustment will happen only for qca99x0, all other chipsets will report proper bin sizes (64/128) without extra 4 bytes being added at the end. The changes are validated in qca99x0 using 10.4 firmware.
