7.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Linus Walleij [ Upstream commit 8e839bca7793a0b03c005f4b2b0825464290d425 ] ResetAudn is active low, but the codec probe only deasserts it. It also clears Clk32kOut2Dis despite claiming to disable that output, and writes codec registers before releasing reset. Pulse ResetAudn before the first audio-bank access and leave the unused 32 kHz output disabled.
