+description: While named "U8500 clocks" these clocks are inside the
+ DB8500 digital baseband system-on-chip and its siblings such as
+ DB8520. These bindings consider the clocks present in the SoC
+ itself, not off-chip clocks. There are four different on-chip
+ clocks - RTC (32 kHz), CPU clock (SMP TWD), PRCMU (power reset and
+ control management unit) clocks and PRCC (peripheral reset and
+ clock controller) clocks. For some reason PRCC 4 does not exist so
+ the itemization can be a bit unintuitive.

-Clock bindings for ST-Ericsson Ux500 clocks
-
-Required properties :
-- compatible : shall contain only one of the following:
- "stericsson,u8500-clks"
- "stericsson,u8540-clks"
- "stericsson,u9540-clks"
-- reg : shall contain base register location and length for
- CLKRST1, 2, 3, 5, and 6 in an array. Note the absence of
- CLKRST4, which does not exist.
-
-Required subnodes:
-- prcmu-clock: a subnode with one clock cell for PRCMU (power,
- reset, control unit) clocks. The cell indicates which PRCMU
- clock in the prcmu-clock node the consumer wants to use.
-- prcc-periph-clock: a subnode with two clock cells for
- PRCC (programmable reset- and clock controller) peripheral clocks.
- The first cell indicates which PRCC block the consumer
- wants to use, possible values are 1, 2, 3, 5, 6. The second
- cell indicates which clock inside the PRCC block it wants,
- possible values are 0 thru 31.
-- prcc-kernel-clock: a subnode with two clock cells for
- PRCC (programmable reset- and clock controller) kernel clocks
- The first cell indicates which PRCC block the consumer
- wants to use, possible values are 1, 2, 3, 5, 6. The second
- cell indicates which clock inside the PRCC block it wants,
- possible values are 0 thru 31.
-- rtc32k-clock: a subnode with zero clock cells for the 32kHz
- RTC clock.
-- smp-twd-clock: a subnode for the ARM SMP Timer Watchdog cluster
- with zero clock cells.
