wlan: WiFi Direct CTS fixs

2016-11-11T01:45:23+00:00

Cylen Yao Details: 1. WiFi Direct CTS tests will fail as supplicant and driver could not keep sync in following case: 1.1 supplicant will request channel when do p2p listen, but driver/firmware has not switch to the target channel when supplicant get remain on channel credit by call driver API of remain on channel; This will make supplicant and driver in unsync state which will make supplicant fail to go to listen state randomly. 1.2 Supplicant and driver will also keep unsync when do mgmt frame TX; supplicant will do other task once mgmt frame TX is returned by calling driver API mgmt_tx, but, driver has not actually TX the mgmt frame out. In extremely case, driver will drop the second mgmt frame if the previous on has not been TX out, just as the group owner test case.

mt6735: Add an RGB configuration sys attr driver for videox/corr10

2016-11-07T12:44:27+00:00

Adds the RGB configuration node which leverages the gamma subsystem to perform color correction. The new node takes rgb triplets that range from 0-2000 each, computes the gamma registers and dispatches them to the gamma correction subsystem. Change-Id: Iac9d3cbd4f423ccfffb8d665c29cfd251767a398
