Subject: [PATCH v3 0/4] i3c: renesas: Add suspend/resume support

Dear All,
This series adds suspend/resume support to the Renesas I3C controller driver.

Thanks & Regards,
Tommaso

v2->v3:
 - PATCH 1/4:
     - Added define for TCLK index.
     - Use devm_clk_bulk_get_all_enabled() into renesas_i3c_probe().
     - Improved commit body.
     - Dropped unnecessary static const char * const renesas_i3c_clks[].
     - Removed the need for per-SoC clock handling and the renesas_i3c_config data.
 - PATCH 2/4:
     - Collected FLi tag.
     - Improved commit body.
 - PATCH 3/4:
     - Collected FLi tag.
     - Improved commit body.
 - PATCH 4/4:
     Fixed error path into renesas_i3c_resume_noirq() and
     renesas_i3c_suspend_noirq() function.

v1->v2:
 - Split patches into smaller chunks.
 - Use clock bulk API.
 - Update patch 4/4 accordingly.

Tommaso Merciai (4):
  i3c: renesas: Switch to clk_bulk API and store clocks in private data
  i3c: renesas: Store clock rate and reset controls in struct
    renesas_i3c
  i3c: renesas: Factor out hardware initialization to separate function
  i3c: renesas: Add suspend/resume support
