Aargh! I can't believe I did that. Inki, Can I do a single patch to which references this one and have you apply them together when the time is right, or do you want me to resend the whole series with an additional patch at the end making the two device tree items optional? I totally forgot, and I'm sorry. adam A

It seems you missed addressing one previous comment from Lucas: "Same as with the earlier patch, this needs to be documented in the DT binding by moving "samsung,burst-clock-frequency" to be a optional property."
[PATCH V7 0/6] drm: bridge: samsung-dsim: Support variable clocking
This series fixes the blanking pack size and the PMS calculation. It then adds support to allows the DSIM to dynamically DPHY clocks, and support non-burst mode while allowing the removal of the hard-coded clock values for the PLL for imx8m mini/nano/plus, and it allows the removal of the burst-clock device tree entry when burst-mode isn't supported by connected devices like an HDMI brige. In that event, the HS clock is set to the value requested by the bridge chip. This has been tested on both an i.MX8M Nano and i.MX8M Plus, and should work on i.MX8M Mini as well. Marek Szyprowski has tested it on various Exynos boards. Adam Ford (5): drm: bridge: samsung-dsim: Fix PMS Calculator on imx8m[mnp] drm: bridge: samsung-dsim: Fetch pll-clock-frequency automatically drm: bridge: samsung-dsim: Select GENERIC_PHY_MIPI_DPHY drm: bridge: samsung-dsim: Dynamically configure DPHY timing drm: bridge: samsung-dsim: Support non-burst mode Lucas Stach (1): drm: bridge: samsung-dsim: fix blanking packet size calculation drivers/gpu/drm/bridge/Kconfig| 1 + drivers/gpu/drm/bridge/samsung-dsim.c | 142 +- include/drm/bridge/samsung-dsim.h | 4 + 3 files changed, 124 insertions(+), 23 deletions(-) V7: Move messages indicating the optional device tree items are going to be automatically read elsewhere was move to dev_dbg instead of dev_info. Cleaned up some of the comments to be a bit more clear. Eliminated a double variable assignement accidentally introduced in V6 when some of the items were moved from patch 6 to patch 5. V6: Squash-in an additional error fix from Lucas Stach regarding the DPHY calcuations. Remove the dynamic_dphy variable and let everyone use the new calculations. Move the hs_clock caching from patch 6 to patch 5 to go along with the DPHY calcuations since they are now based on the recorded hs_clock rate. V5: Update error message to dev_info and change them to indicate what is happening without sounding like an error when optional device tree entries are missing. V4: Undo some accidental whitespace changes, rename PS_TO_CYCLE variables to ps and hz from PS and MHz. Remove if check before the samsung_dsim_set_phy_ctrl call since it's unnecessary. Added additional tested-by and reviewed-by comments. Squash patches 6 and 7 together since the supporting non-burst (patch 6) mode doesn't really work until patch 7 was applied. V3: When checking if the bust-clock is present, only check for it in the device tree, and don't check the presence of the MIPI_DSI_MODE_VIDEO_BURST flag as it breaks an existing Exynos board. Add a new patch to the series to select GENERIC_PHY_MIPI_DPHY in Kconfig otherwise the build breaks on the 32-bit Exynos. Change vco_min variable name to min_freq Added tested-by from Chen-Yu Tsai V2: Instead of using my packet blanking calculation, this integrates on from Lucas Stach which gets modified later in the series to cache the value of the HS-clock instead of having to do the calucations again. Instead of completely eliminating the PLL clock frequency from the device tree, this makes it optional to avoid breaking some Samsung devices. When the samsung,pll-clock-frequency is not found, it reads the value of the clock named "sclk_mipi" This also maintains backwards compatibility with older device trees. This also changes the DPHY calcuation from a Look-up table, a reverse engineered algorithm which uses phy_mipi_dphy_get_default_config to determine the standard nominal values and calculates the cycles necessary to update the DPHY timings accordingly. -- 2.39.2
