2021-01-24serial: add uart driver for MediaTek MT7620 SoCWeijie Gao1-0/+1
This patch adds uart support for MediaTek MT7620 and earlier SoCs. The UART used by MT7620 is incompatible with the ns16550a driver. All registers of this UART have different addresses. A special 16-bit register for Divisor Latch is used to set the baudrate instead of the original two 8-bit registers (DLL and DLM). The driver supports of-platdata which is useful for tiny SPL.

2018-11-29serial: MediaTek: add high-speed uart driver for MediaTek SoCsRyder Lee1-0/+1
Many SoCs from MediaTek have a high-speed uart. This UART is compatible with the ns16550 in legacy mode. It has extra registers for high-speed mode which can reach a maximum baudrate at 921600. However this UART will no longer be compatible if it's in high-speed mode. Some BootROM of MediaTek's SoCs will change the UART into high-speed mode and the U-Boot must use this driver to initialize the UART.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-3/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-04-11serial: Fix Makefile during SPL and TPL buildMarek Vasut1-2/+18
This patch fixes a situation where CONFIG_DM_SERIAL is enabled for regular U-Boot and SPL, but not for TPL. In that case, the build will try to include serial-uclass into the TPL nonetheless, because CONFIG_DM_SERIAL is set. The solution is to check if the build is for SPL or TPL and in that case, check if CONFIG_$(SPL_TPL_)DM_SERIAL is also set. Only in that case, include serial-uclass.c . If the build is for regular U-Boot, CONFIG_BUILD is not set, so only check if CONFIG_DM_SERIAL is set and if so, include serial-uclass.c Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Simon Glass <sjg@chromium.org> Cc: Tom Rini <trini@konsulko.com>

Add a specific serial driver for Intel MID platforms. It has special fractional divider which can be programmed via UART_PS, UART_MUL, and UART_DIV registers. The UART clock is calculated as UART clock = XTAL * UART_MUL / UART_DIV The baudrate is calculated as baud rate = UART clock / UART_PS / DLAB Initialize fractional divider correctly for Intel Edison platform. For backward compatibility we have to set initial DLAB value to 16 and speed to 115200 baud, where initial frequency is 29491200Hz, and XTAL frequency is 38.4MHz.
