If anyone has any objections, please let me know. ------------------ From: Nuno Sa [ Upstream commit 47f3f5a82a31527e027929c5cec3dd1ef5ef30f5 ] In order to access the registers of the HW, we need to make sure that the AXI bus clock is enabled. Hence let's increase the number of clocks by one and add clock-names to differentiate between parent clocks and the bus clock.
