5d1aac358f arm: dts: k3-*-r5: Remove clocks from mcu_timer0
Updated PLL driver sequencing requires us to use udelay in the PLL
driver as there is no poll bit to get the status of operations.
tick-timer(mcu_timer0/main_timer0) setting up the clocks for itself is
something that won't work as the PLL driver will be using udelay and
PLLs are configured during clock probe which would end up in a recursive
probe.

tick-timer being used by K3 devices are configured by ROM and we really
don't need to configure any of the clocks.

Remove the clock dependency from R5 stage as we don't need to setup
clocks for it.

8659144ae5 arm: dts: k3-*-r5: Add MPU clock in clocks property
MPU clock had been missing. Distinguish multiple clocks with clock-names
and add MPU clock as well.

939f17c8a9 arm: dts: k3-j721s2-r5: Change GTC clock parent
MAIN_PLL0 has a flag set in DM (Device Manager) that removes its
capability to re-initialise clock frequencies. A72 CPU clock (GTC) and
RGMII has MAIN_PLL3 as their parent which does not have this flag. While
RGMII needs re-initialization to default frequency to be able to get
250MHz with its divider, GTC can not get its required 200MHz with its
dividers. Thus move GTC clock parent on J721S2 from MAIN_PLL3_HSDIV1 to
MAIN_PLL0_HSDIV6. This was already done on CPTS node in kernel which was
similarly affected (linked).

512863ecfe arch: arm: dts: k3-j721s2-r5: Override ospi and fss for 32-bit mode
R5 being a 32-bit processor can't understand the 64-bit mapping being
done in ospi node. Override the ospi node for 32-bit register ranges and
the fss node ( the parent node of ospi ) to map the ranges for the
updated child node correctly.

e84b004abc arch: arm: dts: k3-j721s2-r5: Introduce k3-j721s2-r5.dtsi
Create an SoC R5 dtsi file that could be used at board level R5 files. This
would help in keeping the SoC level changes in sync across board files.
