* wcnss: Read multiple SMD Packet from SMD ChannelSandeep Singh2019-07-10
| | | | | | | | | | It observe that sometime, there are multiple SMD packets in SMD channel. In current scenario, driver reading one packet at single event. Reading all SMD packets to avoid any packets miss. Change-Id: Id7ef388af6200891b17bbe1456cc2fffa580a3d3 Signed-off-by: Sandeep Singh <sandsing@codeaurora.org>
* wcnss: fix integer underflow in wcnss_wlanSandeep Singh2018-10-09
| | | | | | | | | | | Fix integer underflow which may eventually results in an buffer overread in wcnss_nvbin_dnld when the firmware file size is less than 4 Byte. Add a check on file size before performing arithmetic operation which avoids buffer underflow.

| * wcnss: modularize wcnss power up sequence and debug logsSarada Prasanna Garnayak2017-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modularize the wcnss power up sequence like wcnss voltage regulator enable/disable sequence and voltage regulator current and voltage level parsing method. Remove hack code from the power wcnss power process and enable/disable the power resource if it's defined in the wcnss device node. Update the debug logs to track the exact state of the power state during device bootup. Remove the unnecessary logging for the optional resource request fails during device bootup.
