Subject: [PATCH v9 0/2] i2c: riic: Implement bus recovery

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

Hi all,

This patch series implements bus recovery for the RIIC driver. The first
patch implements the bus recovery mechanism, while the second patch
handles arbitration loss.

v8>->v9:
- Dropped Tested-by and Reviewed-by tags from patch 1/2
- Updated commit message for patch 1/2 to include the new approach
- New patch 2/2 added to handle arbitration loss

v7->v8:
- Included Acks from Andy and Fabrizio.

v6->v7:
- https://lore.kernel.org/all/20250203143511.629140-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

v2->v6:
- Included RB and TB from Claudiu.

v1->v2:
- Used single register read to check SDA/SCL lines

Cheers,
Prabhakar
