Hi,
This patch series adds the IRQC clock to the device tree on SoCs that
have such a clock (r8a73a4 and r8a779x), and adds mininal runtime PM
support to the renesas-irqc driver, to make sure the clock is enabled
when needed by the external IRQ controller(s).
Before, the clock was assumed enabled by the bootloader or reset state.
As usual when involving clocks, the DTS changes depend stricly on the
driver changes. Else the clock will be disabled as assumed unused,
breaking the boot.
This was tested on r8a73a4/ape6evm and r8a7791/koelsch.
Thanks!
