[PATCH v2 1/7] dt-bindings: clock: brcm,kona-ccu: Add BCM21664 bus clocks

From: Artur Weber
Date: Mon Mar 03 2025 - 15:28:12 EST


Add bus clocks for hub_timer, sdio, bsc, uart and usb_otg_ahb to the
allowed clock output names for BCM21664 CCUs and add the relevant
clock IDs to the clock/bcm21664.h dt-bindings header.

Signed-off-by: Artur Weber <aweber.kernel@xxxxxxxxx>
