serial: renesas: Fix R-Car spelling

2024-12-11T07:36:24Z

The correct spelling is R-Car, including the dash, update the usage. Kconfig strings and comment changes only, no functional change. Signed-off-by: Marek Vasut

serial: Support debug UART in TPL

2024-10-03T17:52:16Z

Some boards want to use the debug UART in TPL so add an option for that. Signed-off-by: Simon Glass

drivers: serial: Add xtensa semihosting driver

2024-07-04T22:08:37Z

Add xtensa semihosting driver. It can't use regular semihosting driver as Xtensa's has it's own semihosting ABI. Tested-by: Max Filippov Signed-off-by: Jiaxun Yang

serial: allow selecting MSM debug UART with ARCH_IPQ40XX

2024-04-23T11:29:13Z

Currently, DEBUG_UART_MSM depends on ARCH_SNAPDRAGON only, but IPQ40XX devices also use the same UART HW so they can also use the debug UART. So, allow selecting DEBUG_UART_MSM when using ARCH_IPQ40XX as well. Signed-off-by: Robert Marko Reviewed-by: Caleb Connolly Signed-off-by: Caleb Connolly

ARM: renesas: Rename ARCH_RMOBILE to ARCH_RENESAS

2024-03-02T19:29:36Z

Rename ARCH_RMOBILE to ARCH_RENESAS because all the chips are made by Renesas, while only a subset of them is from the R-Mobile line. Use the following command to perform the rename: " $ git grep -l 'ARCH_RMOBILE' | xargs -I {} sed -i 's@ARCH_RMOBILE@ARCH_RENESAS@g' {} " Signed-off-by: Marek Vasut Reviewed-by: Paul Barker

serial: msm: add debug UART

2024-03-01T14:44:35Z

Introduce support for early debugging. This relies on the previous stage bootloader to initialise the UART clocks, when running with U-Boot as the primary bootloader this feature doesn't work. It will require a way to configure the clocks before the driver model is available. Reviewed-by: Neil Armstrong Reviewed-by: Sumit Garg Signed-off-by: Caleb Connolly

serial: msm-geni: don't rely on parent misc device

2024-01-16T12:26:52Z

commit 1b15483deb3f ("misc: add Qualcomm GENI SE QUP device driver") introduced support for platform-specific oversampling values, necessary to configure the UART clocks on all platforms at runtime. However it relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag, this is not done consistently during boot. Instead, take another approach by relying on ofnode_ helpers to read the serial engine base address and do the read directly. This fixes early UART on boards with a non-default oversampling rate.

serial: zynqmp: Fetch baudrate from dtb and update

2023-11-07T12:47:08Z

The baudrate configured in .config is taken by default by serial. If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial. So, the environment also needs to be updated with the dtb baudrate to avoid the glitches on the serial. Also add test to cover this new function.

configs: Add support in Kconfig and convert for armada boards

2023-11-07T12:47:08Z

Move the DEFAULT_ENV_IS_RW to Kconfig for easier configuration. Hence, add the CONFIG_DEFAULT_ENV_IS_RW config to the defconfig files to allow enabling them for armada boards.
