The Trogdor Homestar DTSI adds additional GPIO52 pin to secondary I2S pins ("sec_mi2s_active") and configures it to "mi2s_1" function. The Trogdor DTSI (which is included by Homestar) configures drive strength and bias for all "sec_mi2s_active" pins, thus the intention was to apply this configuration also to GPIO52 on Homestar.
