If anyone has any objections, please let me know. ------------------ From: Chen-Yu Tsai commit 2f1aab0cb0661d533f008e4975325080351cdfc8 upstream. The GPU SRAM supply is supposed to be always at least 0.1V higher than the GPU supply. However when the DT was upstreamed, the spread was incorrectly set to 0.01V.
