Commit Message

Artur Weber March 8, 2025, 7:50 a.m. UTC 
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.

Changes in v3:
- Fix UARTBx_APB clocks being out of order in DT binding header
- Drop CLOCK_COUNT defines from DT binding header

Changes in v2:
- Move clock ID dt-bindings header changes into this commit
