Sorry about that! Will add to v3. Tomi

Thanks Tomi for the updates, I cannot test it or verify against the datasheet, but codewise the series looks nice: Reviewed-by: Peter Ujfalusi <peter.ujfalusi@gmail.com> > > Tomi > > Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> > --- > Changes in v2: > - Add "drm/tegra: rgb: Parameterize V- and H-sync polarities" so that > Tegra can configure the polarities correctly. > - Add "drm/bridge: tc358768: Default to positive h/v syncs" as we don't > (necessarily) have the polarities set in the mode. > - Drop "drm/bridge: tc358768: Add DRM_BRIDGE_ATTACH_NO_CONNECTOR > support" as it's not needed for DRM_BRIDGE_ATTACH_NO_CONNECTOR > support. > - Link to v1: https://lore.kernel.org/r/20230804-tc358768-v1-0-1afd44b7826b@ideasonboard.com > > --- > Thierry Reding (1): > drm/tegra: rgb: Parameterize V- and H-sync polarities > > Tomi Valkeinen (11): > drm/bridge: tc358768: Fix use of uninitialized variable > drm/bridge: tc358768: Fix bit updates > drm/bridge: tc358768: Cleanup PLL calculations > drm/bridge: tc358768: Use struct videomode > drm/bridge: tc358768: Print logical values, not raw register values > drm/bridge: tc358768: Use dev for dbg prints, not priv->dev > drm/bridge: tc358768: Rename dsibclk to hsbyteclk > drm/bridge: tc358768: Clean up clock period code > drm/bridge: tc358768: Fix tc358768_ns_to_cnt() > drm/bridge: tc358768: Attempt to fix DSI horizontal timings > drm/bridge: tc358768: Default to positive h/v syncs > > drivers/gpu/drm/bridge/tc358768.c | 381 ++++++++++++++++++++++++++++---------- > drivers/gpu/drm/tegra/rgb.c | 16 +- > 2 files changed, 295 insertions(+), 102 deletions(-) > --- > base-commit: 4d49d87b3606369c6e29b9d051892ee1a6fc4e75 > change-id: 20230804-tc358768-1b6949ef2e3d > > Best regards,
This series contains various fixes and cleanups for TC358768. The target of this work is to get TC358768 working on Toradex's AM62 based board, which has the following display pipeline: AM62 DPI -> TC358768 -> LT8912B -> HDMI connector The main thing the series does is to improve the DSI HSW, HFP and VSDly calculations. Tomi Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> --- Changes in v2: - Add "drm/tegra: rgb: Parameterize V- and H-sync polarities" so that Tegra can configure the polarities correctly. - Add "drm/bridge: tc358768: Default to positive h/v syncs" as we don't (necessarily) have the polarities set in the mode. - Drop "drm/bridge: tc358768: Add DRM_BRIDGE_ATTACH_NO_CONNECTOR support" as it's not needed for DRM_BRIDGE_ATTACH_NO_CONNECTOR support. - Link to v1: https://lore.kernel.org/r/20230804-tc358768-v1-0-1afd44b7826b@ideasonboard.com --- Thierry Reding (1): drm/tegra: rgb: Parameterize V- and H-sync polarities Tomi Valkeinen (11): drm/bridge: tc358768: Fix use of uninitialized variable drm/bridge: tc358768: Fix bit updates drm/bridge: tc358768: Cleanup PLL calculations drm/bridge: tc358768: Use struct videomode drm/bridge: tc358768: Print logical values, not raw register values drm/bridge: tc358768: Use dev for dbg prints, not priv->dev drm/bridge: tc358768: Rename dsibclk to hsbyteclk drm/bridge: tc358768: Clean up clock period code drm/bridge: tc358768: Fix tc358768_ns_to_cnt() drm/bridge: tc358768: Attempt to fix DSI horizontal timings drm/bridge: tc358768: Default to positive h/v syncs drivers/gpu/drm/bridge/tc358768.c | 381 ++++++++++++++++++++++++++++---------- drivers/gpu/drm/tegra/rgb.c | 16 +- 2 files changed, 295 insertions(+), 102 deletions(-) --- base-commit: 4d49d87b3606369c6e29b9d051892ee1a6fc4e75 change-id: 20230804-tc358768-1b6949ef2e3d Best regards,
