The above is perhaps true for ISP8000, but ISP8000Nano does not have CROP_ENABLE bit, and the CFG_UPD and CFG_UPD_AUTO are at the same locations as on RK3399. I don't have documentation to prove this, but experimentation shows that this is the case.

I agree with you. The missing CROP_ENABLE bit matches the missing resizer input crop capability in the i.MX8MP. I don't know if that's specific to the i.MX8MP, specific to the ISP8000Nano, or common to all ISP8000 versions when the instance is synthesized with a single path (which may be what ISP8000Nano is). > > --- > > Changes since v3: > > > > - Condition on RKISP1_FEATURE_DUAL_CROP feature > > - Update commit message > > > > Changes since v2: > > > > - Condition on RKISP1_FEATURE_RSZ_CROP feature > > - Rename bits > > - Use the rkisp1_has_feature() macro > > > > .../media/platform/rockchip/rkisp1/rkisp1-regs.h | 5 +++++ > > .../platform/rockchip/rkisp1/rkisp1-resizer.c | 15 +++++++++++---- > > 2 files changed, 16 insertions(+), 4 deletions(-) > > > > diff --git a/drivers/media/platform/rockchip/rkisp1/rkisp1-regs.h b/drivers/media/platform/rockchip/rkisp1/rkisp1-regs.h > > index 3b19c8411360..95646b45f28b 100644 > > --- a/drivers/media/platform/rockchip/rkisp1/rkisp1-regs.h > > +++ b/drivers/media/platform/rockchip/rkisp1/rkisp1-regs.h > > @@ -168,6 +168,11 @@ > > #define RKISP1_CIF_RSZ_CTRL_CFG_UPD_AUTO BIT(9) > > #define RKISP1_CIF_RSZ_SCALER_FACTOR BIT(16) > > > > +/* For resizer instances that support cropping */ > > +#define RKISP1_CIF_RSZ_CTRL_CROP_ENABLE BIT(8) > > +#define RKISP1_CIF_RSZ_CTRL_CROP_CFG_UPD BIT(9) > > +#define RKISP1_CIF_RSZ_CTRL_CROP_CFG_UPD_AUTO BIT(10) > > + > > /* MI_IMSC - MI_MIS - MI_RIS - MI_ICR - MI_ISR */ > > #define RKISP1_CIF_MI_FRAME(stream) BIT((stream)->id) > > #define RKISP1_CIF_MI_MBLK_LINE BIT(2) > > diff --git a/drivers/media/platform/rockchip/rkisp1/rkisp1-resizer.c b/drivers/media/platform/rockchip/rkisp1/rkisp1-resizer.c > > index c1aaeed58acc..6d6ebc53c6e5 100644 > > --- a/drivers/media/platform/rockchip/rkisp1/rkisp1-resizer.c > > +++ b/drivers/media/platform/rockchip/rkisp1/rkisp1-resizer.c > > @@ -178,10 +178,17 @@ static void rkisp1_rsz_update_shadow(struct rkisp1_resizer *rsz, > > { > > u32 ctrl_cfg = rkisp1_rsz_read(rsz, RKISP1_CIF_RSZ_CTRL); > > > > - if (when == RKISP1_SHADOW_REGS_ASYNC) > > - ctrl_cfg |= RKISP1_CIF_RSZ_CTRL_CFG_UPD_AUTO; > > - else > > - ctrl_cfg |= RKISP1_CIF_RSZ_CTRL_CFG_UPD; > > + if (when == RKISP1_SHADOW_REGS_ASYNC) { > > + if (rkisp1_has_feature(rsz->rkisp1, DUAL_CROP)) > > + ctrl_cfg |= RKISP1_CIF_RSZ_CTRL_CFG_UPD_AUTO; > > + else > > + ctrl_cfg |= RKISP1_CIF_RSZ_CTRL_CROP_CFG_UPD_AUTO; > > + } else { > > + if (rkisp1_has_feature(rsz->rkisp1, DUAL_CROP)) > > + ctrl_cfg |= RKISP1_CIF_RSZ_CTRL_CFG_UPD; > > + else > > + ctrl_cfg |= RKISP1_CIF_RSZ_CTRL_CROP_CFG_UPD; > > + } > > > > rkisp1_rsz_write(rsz, RKISP1_CIF_RSZ_CTRL, ctrl_cfg); > > }
