From 21a1989963b4c2d8530af9be41c4cc2f7d3b2ee8 Mon Sep 17 00:00:00 2001 From: Aradhya Bhatia Date: Mon, 30 Oct 2023 20:58:34 +0530 Subject: [PATCH 1/5] arm64: defconfig: Enable Toshiba TC358767 bridge Siemens' SIMATIC IOT2050 platform[0], based on Texas Instruments' AM65x SoC[1], uses Toshiba TC358767[2] to convert DPI video to DisplayPort (DP) video output. The original DPI signals are generated by AM65x's Display SubSystem (DSS). Toshiba TC358767 is also capable of other video format conversions, viz, DPI to (e)DP, DSI to (e)DP, and DSI to DPI. Enable the video bridge Toshiba TC358767.

This subsystem is provided for the use cases like implementation of custom peripheral interfaces, offloading of tasks from the other processor cores of the SoC, etc. Currently AM654x-EVM uses ICSSG driver.

No need to change CONFIG_SERIAL_8250_RUNTIME_UARTS, see commit 9d86719f8769 ("serial: 8250: Allow using ports higher than SERIAL_8250_RUNTIME_UARTS"). The need to increase this value was noticed while working with Toradex Verdin AM62, this board has 4 serial UART instances available to the user plus an internal one that is connected to a Bluetooth module. Without this change the fifth UART connected to the BT module is not instantiated and BT is not working. Instead of increasing the number to the bare minimum (5) that would be required to solve this specific issue, we increase this to 8 which seems a more reasonable number to have in the defconfig and should cover more valid use cases. With this change the kernel image size increases by ~3.2kB. bloat-o-meter summary: add/remove: 1/1 grow/shrink: 7/0 up/down: 3220/-8 (3212) Cc: Tony Lindgren Reviewed-by: Tony Lindgren Signed-off-by: Francesco Dolcini Link: https://lore.kernel.org/r/20231201195732.4931-1-francesco@dolcini.it Signed-off-by: Nishanth Menon --- arch/arm64/configs/defconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/configs/defconfig b/arch/arm64/configs/defconfig index 329031271148..755c9de16fbb 100644 --- a/arch/arm64/configs/defconfig +++ b/arch/arm64/configs/defconfig @@ -449,6 +449,7 @@ CONFIG_SERIO_AMBAKMI=y CONFIG_LEGACY_PTY_COUNT=16 CONFIG_SERIAL_8250=y CONFIG_SERIAL_8250_CONSOLE=y +CONFIG_SERIAL_8250_NR_UARTS=8 CONFIG_SERIAL_8250_EXTENDED=y CONFIG_SERIAL_8250_SHARE_IRQ=y CONFIG_SERIAL_8250_BCM2835AUX=y From bd62d91f42d015e173809214badaf750b75be2d1 Mon Sep 17 00:00:00 2001 From: Jai Luthra Date: Fri, 1 Dec 2023 10:39:16 +0530 Subject: [PATCH 4/5] arm64: defconfig: Enable J721E CSI2RX AM62 and other K3 based SoCs use Cadence DPHY and CSI-RX bridge drivers, along with a DMA wrapper CSI IP for the camera pipeline.
