ARM: OMAP: board-omap4panda: Pin mux configuration for audio needs
u-boot stopped configuring 'non essential' pins recently. These pins are essential for audio and need to be done to have working audio on the board. Pin Mux configuration for: twl6040 audpwron gpio, McPDM, and McBSP1. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
