It has the following sub modules MAU, CTU, RPF, DPR, LUT, BRS, WPF and LIF. The VSPD block on RZ/G2L does not have a version register, so added a new compatible string "renesas,rzg2l-vsp2" with a data pointer containing the info structure. Also the reset line is shared with the DU module. v3->v4: * Restored error check for pm_runtime_resume_and_get and calls assert() in case of failure. * Added Rb tag from Geert * Add switch() for LIF0 buffer attribute handling for RZ/G2L and V3M SoC's v2->v3: * Added Rb tags from Krzysztof and Philipp * If reset_control_deassert() failed, return ret directly. * Fixed version comparison in vsp1_lookup() v1->v2: * Used reference counted reset handle to perform deassert/assert * Changed the compatible from vsp2-rzg2l->rzg2l-vsp2 * Added standalone device info for rzg2l-vsp2. * Added vsp1_lookup helper function. * Updated comments for LIF0 buffer attribute register * Used last ID for rzg2l-vsp2. RFC->v1: * Added reset support as separate patch * Moved rstc just after the bus_master field in struct vsp1_device * Used data pointer containing info structure to retrieve version information * Updated commit description * Changed compatible from vsp2-r9a07g044->vsp2-rzg2l * Defined the clocks * Clock max Items is based on SoC Compatible string RFC: * https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220112174612.10773-21-biju.das.jz@bp.renesas.com/ * https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220112174612.10773-20-biju.das.jz@bp.renesas.com/ Biju Das (3): media: dt-bindings: media: renesas,vsp1: Document RZ/{G2L,V2L} VSPD bindings media: vsp1: Add support to deassert/assert reset line media: vsp1: Add support for RZ/G2L VSPD .../bindings/media/renesas,vsp1.yaml | 52 ++++++++++++---- drivers/media/platform/vsp1/vsp1.h | 1 + drivers/media/platform/vsp1/vsp1_drv.c | 62 +++++++++++++++---- drivers/media/platform/vsp1/vsp1_lif.c | 16 +++-- drivers/media/platform/vsp1/vsp1_regs.h | 2 + 5 files changed, 103 insertions(+), 30 deletions(-)
