Subject: [PATCH v2 0/2] clk: renesas: RZ/G2L: Add support for no PM clocks

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series adds support for indicating MOD clocks as no PM
(if any). SoCs indicate no PM clocks by adding to no_pm_mod_clks[]
array.

Note this patch applies on top of [0] (rebased on renesas-clk-for-v6.2
branch).

v1 -> v2
* Dropped DEF_NO_PM() macro
* Added genpd member to struct rzg2l_cpg_priv
* Added no_pm_mod_clks and num_no_pm_mod_clks members
  to struct rzg2l_cpg_info
* Updated commit messages

RFC->v1
* Added no_pm_mod_clks and num_no_pm_mod_clks members as part of
  struct rzg2l_cpg_priv so that we dont loop the entire mod clocks
  array for each device probe.
* Patch#2 unchanged

RFC: https://patchwork.kernel.org/project/linux-renesas-soc/cover/20220927203044.751611-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

Cheers,
Prabhakar

  clk: renesas: rzg2l: Don't assume all CPG_MOD clocks support PM
  clk: renesas: r9a07g044: Add CRU_SYSCLK and CRU_VCLK to no PM list
