drm: bridge: samsung-dsim: Fix PMS Calculator on imx8m[mnp]

2023-07-19T14:35:52+00:00

[ Upstream commit 54f1a83c72250b182fa7722b0c5f6eb5e769598d ] According to Table 13-45 of the i.MX8M Mini Reference Manual, the min and max values for M and the frequency range for the VCO_out calculator were incorrect. This information was contradicted in other parts of the mini, nano and plus manuals. After reaching out to my NXP Rep, when confronting him about discrepencies in the Nano manual, he responded with: "Yes it is definitely wrong, the one that is part of the NOTE in MIPI_DPHY_M_PLLPMS register table against PMS_P, PMS_M and PMS_S is not correct. I will report this to Doc team, the one customer should be take into account is the Table 13-40 DPHY PLL Parameters and the Note above." These updated values also match what is used in the NXP downstream kernel. To fix this, make new variables to hold the min and max values of m and the minimum value of VCO_out, and update the PMS calculator to use these new variables instead of using hard-coded values to keep the backwards compatibility with other parts using this driver.

drm: bridge: samsung-dsim: Add i.MX8M Plus support

2023-03-28T00:05:41+00:00

Add extras to support i.MX8M Plus. The main change is the removal of HS/VS/DE signal inversion in the LCDIFv3-DSIM glue logic, otherwise the implementation of this IP in i.MX8M Plus is very much compatible with the i.MX8M Mini/Nano one.

drm: bridge: Generalize Exynos-DSI driver into a Samsung DSIM bridge

2023-03-28T00:05:41+00:00

Samsung MIPI DSIM controller is common DSI IP that can be used in various SoCs like Exynos, i.MX8M Mini/Nano. In order to access this DSI controller between various platform SoCs, the ideal way to incorporate this in the drm stack is via the drm bridge driver. We already have a consolidated code for supporting component and bridge based DRM drivers, so keep the exynos component based code in existing exynos_drm_dsi.c and move generic bridge code as part of samsung-dsim.c Tested-by: Marek Szyprowski Reviewed-by: Marek Vasut Signed-off-by: Marek Szyprowski Signed-off-by: Jagan Teki Signed-off-by: Inki Dae

drm: bridge: dw-hdmi: Attach to next bridge if available

2021-07-28T13:33:13+00:00

On all platforms except i.MX and Rockchip, the dw-hdmi DT bindings require a video output port connected to an HDMI sink (most likely an HDMI connector, in rare cases another bridges converting HDMI to another protocol). For those platforms, retrieve the next bridge and attach it from the dw-hdmi bridge attach handler.

drm/bridge/synopsys: dw-hdmi: Add an option to suppress loading CEC driver

2021-04-20T15:22:38+00:00

This adds DW-HDMI driver a glue option to disable loading of the CEC sub-driver. On some SoCs, the CEC functionality is enabled in the IP config bits, but the CEC bus is non-functional like on Amlogic SoCs, where the CEC config bit is set but the DW-HDMI CEC signal is not connected to a physical pin, leading to some confusion when the DW-HDMI CEC controller can't communicate on the bus.
