0f4effb05b bus: ti: am33xx: add pwm subsystem driver
The TI PWMSS driver is a simple bus driver for providing clock and power
management for the PWM peripherals on TI AM33xx SoCs, namely eCAP,
eHRPWM and eQEP.

For DT binding details see Linux doc:
- Documentation/devicetree/bindings/pwm/pwm-tipwmss.txt

92cc4e1c21 bus: ti: add minimal sysc interconnect target driver
We can handle the sysc interconnect target module in a generic way for
many TI SoCs. Initially let's just enable domain clocks before the
children are probed.

The code is loosely based on the drivers/bus/ti-sysc.c of the Linux
kernel version 5.9-rc7.

e2bb0be2fc bus: uniphier-system-bus: add UniPhier System Bus driver
Since commit 1517126fda ("ARM: uniphier: select DM_ETH"), DM-based
drivers/net/smc911x.c is compiled, but it is never probed because the
parent node lacks the DM-based driver.

I need a skeleton driver to populate child devices (but the next commit
will move more hardware settings to the this driver).

I put this to drivers/bus/uniphier-system-bus.c because this is the
same path as the driver in Linux kernel.
