Subject: [PATCH 0/4] dmaengine: sh: rz-dmac: Add system sleep PM support

Dear All,

This patch series improves runtime PM support and adds system sleep PM ops for
supporting deep sleep in the rz-dmac driver.

It also refactors the driver to use the newly added devm_pm_runtime_enable()
and rz_dmac_reset_control_assert() functions for reset cleanup handling.

Thanks & Regards,
Tommaso
