Thus, use MSM DSC helper to calculate hdisplay for dsi_timing_setup instead of directly using mode->hdisplay. Changes in v3: - Split from previous patch - Initialized hdisplay as uncompressed pclk per line at the beginning of dsi_timing_setup as to not break dual DSI calculations Changes in v4: - Moved pclk_per_intf calculations to DSC hdisplay adjustments Signed-off-by: Jessica Zhang Reviewed-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/dsi/dsi_host.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/msm/dsi/dsi_host.c b/drivers/gpu/drm/msm/dsi/dsi_host.c index 6a6218a9655f..412339cc9301 100644 --- a/drivers/gpu/drm/msm/dsi/dsi_host.c +++ b/drivers/gpu/drm/msm/dsi/dsi_host.c @@ -958,7 +958,7 @@ static void dsi_timing_setup(struct msm_dsi_host *msm_host, bool is_bonded_dsi) * pulse width same */ h_total -= hdisplay; - hdisplay /= 3; + hdisplay = msm_dsc_get_pclk_per_intf(msm_host->dsc) / 3; h_total += hdisplay; ha_end = ha_start + hdisplay; }
