If anyone has any objections, please let me know. ------------------ From: Paul Cercueil [ Upstream commit 45ba63a29fd9b8a461110185e3abc5b4c90b806a ] When the main processor goes idle, by default its clock is stopped. However, this also stops the clock of the co-processor. Here, if the C1CLK clock is enabled, we disable this functionality.
