Hello All, These 2 patches add the atomic check hook for sn65dsi86 bridge and does a minor math fix for dsi rate calculation. According to the datasheet[0], for the max resolution, it says: Suitable for 60 fps 4K 4096 x 2304 resolution at 18 bpp color, and WUXGA 1920 x 1200 resolution with 3D graphics at 60 fps (120 fps equivalent) A very usual clock frequency for 4K@60fps resolution is 594MHz. So keeping the max value supported by the bridge as 600MHz for safe check. DSI clock frequency range check are as per datasheet[0]. Changelog v1->v2: - Check the value in atomic_check hook - Fix the "Fixes" tag - Fix MAX_DSI_CLK_RANGE to reflect actual supported value - Add mode_clock check to ensure that the bit_rate_khz variable does not overflow instead of justifying by reverse calculation in comments. - Fix commit message to show that the math uissue was found during code inspection. v1 patch: <https://lore.kernel.org/all/20240408073623.186489-1-j-choudhary@xxxxxx/> [0]: <https://www.ti.com/lit/gpn/sn65dsi86> Jayesh Choudhary (2): drm/bridge: ti-sn65dsi86: Add atomic_check hook for the bridge drm/bridge: ti-sn65dsi86: Fix ti_sn_bridge_set_dsi_rate function drivers/gpu/drm/bridge/ti-sn65dsi86.c | 67 +++++++++++++++++++-------- 1 file changed, 47 insertions(+), 20 deletions(-) -- 2.25.1
