I've modified the title and message as: drm/mediatek: dsi: Use symbolized register definition For HSTX_CKLP_EN and DIS_EOT, use symbolized register definition instead of magic number. And applied to mediatek-drm-next [1], thanks. https://git.kernel.org/pub/scm/linux/kernel/git/chunkuang.hu/linux.git/log/?h=mediatek-drm-next Regards, Chun-Kuang. > > Signed-off-by: Jitao Shi <jitao.shi@mediatek.com> > --- > drivers/gpu/drm/mediatek/mtk_dsi.c | 7 +++++-- > 1 file changed, 5 insertions(+), 2 deletions(-) > > diff --git a/drivers/gpu/drm/mediatek/mtk_dsi.c b/drivers/gpu/drm/mediatek/mtk_dsi.c > index 65fd99c528af..2bc46f2350f1 100644 > --- a/drivers/gpu/drm/mediatek/mtk_dsi.c > +++ b/drivers/gpu/drm/mediatek/mtk_dsi.c > @@ -401,8 +401,11 @@ static void mtk_dsi_rxtx_control(struct mtk_dsi *dsi) > break; > } > > - tmp_reg |= (dsi->mode_flags & MIPI_DSI_CLOCK_NON_CONTINUOUS) << 6; > - tmp_reg |= (dsi->mode_flags & MIPI_DSI_MODE_EOT_PACKET) >> 3; > + if (dsi->mode_flags & MIPI_DSI_CLOCK_NON_CONTINUOUS) > + tmp_reg |= HSTX_CKLP_EN; > + > + if (!(dsi->mode_flags & MIPI_DSI_MODE_EOT_PACKET)) > + tmp_reg |= DIS_EOT; > > writel(tmp_reg, dsi->regs + DSI_TXRX_CTRL); > } > -- > 2.12.5 > _______________________________________________ > dri-devel mailing list > dri-devel@lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/dri-devel
