From 5598db254fe34cb9b3557fcfba915d90725bf173 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Fri, 8 Dec 2017 16:42:59 -0800 Subject: google/gru: Stop mucking with unused I2S0 pins in codec config Due to a schematic error, our code was written to configure more I2S0 pins than are actually used. We're also pinmuxing the whole bank of pins over to the I2S controller even though we don't need them all. Restrict the GPIO initialization and pinmuxing to the pins we really need so the other ones can be correctly used as SKU ID pins on Scarlet. Also, move the "audio" IO voltage domain selection to the other such selections in the bootblock, since that covers two whole banks of GPIOs and there's no guarantee that they're all used for audio (and thus not needed before ramstage). BUG=b:69373077 TEST=Booted Scarlet, confirmed correct SKU ID (7) was detected on rev2.
