The added support for firmware version 6 and > higher was not taking into account the DISPLAY_DELAY_ENABLE boolean. > Instead it had a comment stating that DISPLAY_DELAY should be set to a > negative value to disable it. This is not possible since the control > range is from 0 to 65535. This feature was also supposed to be disabled > by default in order to produce frames in display order. > > Signed-off-by: Nicolas Dufresne <nicolas.dufresne@xxxxxxxxxxxxx> Acked-by: Kamil Debski <k.debski@xxxxxxxxxxx> > --- > drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c | 6 +----- > 1 file changed, 1 insertion(+), 5 deletions(-) > > diff --git a/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > b/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > index 92032a0..0675515 100644 > --- a/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > +++ b/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > @@ -1340,11 +1340,7 @@ static int s5p_mfc_init_decode_v6(struct > s5p_mfc_ctx *ctx) > /* FMO_ASO_CTRL - 0: Enable, 1: Disable */ > reg |= (fmo_aso_ctrl << S5P_FIMV_D_OPT_FMO_ASO_CTRL_MASK_V6); > > - /* When user sets desplay_delay to 0, > - * It works as "display_delay enable" and delay set to 0. > - * If user wants display_delay disable, It should be > - * set to negative value. */ > - if (ctx->display_delay >= 0) { > + if (ctx->display_delay_enable) { > reg |= (0x1 << S5P_FIMV_D_OPT_DDELAY_EN_SHIFT_V6); > writel(ctx->display_delay, mfc_regs->d_display_delay); > } > -- > 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
