Subject: [PATCH v2 0/8] clk: renesas: rzg2l-cpg: Drop PM domain abstraction for MSTOP

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Hi,

Series drops the PM domain abstraction for MSTOP to comply with the
requirements received from the hardware team regarding the configuration
sequence b/w the MSTOP and CLKON bits of individual modules.

The initial MSTOP support for RZ/G3S was proposed here:
https://lore.kernel.org/all/20231120070024.4079344-4-claudiu.beznea.uj@bp.renesas.com/

There are no DT users of this abstraction yet.

Please share your thoughts.

Thank you,
Claudiu Beznea

Changes in v2:
- updated the title and description for patches 1/8, 2/8 along
  with their content
- added patch 3/8
- collected tags
- drop duplicated mstop lists in patch 4/8
- detailed changelog for each patch can be found in the individual
  patch
