serial: mxs: Add MXS AUART driver

2023-05-21T14:54:41Z

Add trivial driver for the MXS AUART IP. This is the other UART IP present in i.MX23 and i.MX28, used to drive the non-DUART ports. Signed-off-by: Marek Vasut

x86: Allow locating the UART from ACPI tables

2023-05-11T02:25:29Z

When coreboot does not pass a UART in its sysinfo struct, there is no easy way to find it out. Since coreboot does not actually init the serial device when serial is disabled, it is not possible to make it add this information to the sysinfo table. Add a way to obtain this information from the DBG2 ACPI table, which is normally set up by coreboot. For now this only supports a memory-mapped 16550-style UART.

serial: msm-geni: correct oversampling value based on QUP hardware revision

2023-05-02T18:23:59Z

Starting from QUP v2.5 the value of oversampling is changed from 32 to 16, keeping the old value on newer platforms results on wrong set UART IP clock divider, thus the asked baudrate does not correspond to the actually set with all the consequencies for a user. The change links the driver to a new Qualcomm GENI SE QUP driver to get its hardware version and update the oversampling value. Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched, since a wanted baudrate can be controlled by setting a modified CONFIG_DEBUG_UART_CLOCK build time variable.

serial: sh: Add DEBUG_UART support

2023-03-18T11:04:02Z

Add support for debug output very early during boot using the DEBUG_UART mechanism. This uses a static fixed UART port configuration selected via Kconfig options and dedicated print functions from debug_uart.h. This is useful e.g. when debugging problems so early during boot, that not even the DM is initialized at that point, and thus DM_SERIAL is not available either. This functionality is disabled by default. To activate it, define the following Kconfig options and select SCIF type using CFG_SCI/CFG_SCIF_A/ CFG_HSCIF/: CONFIG_DEBUG_UART=y CONFIG_DEBUG_UART_SCIF=y CONFIG_DEBUG_UART_BASE=0xe6540000 CONFIG_DEBUG_UART_CLOCK=24000000 The later two options define the SCIF physical base address and SCIF input clock in Hz. Optionally, to validate DEBUG_UART works, enable the following as well to get early serial output message by default: CONFIG_DEBUG_UART_ANNOUNCE=y Signed-off-by: Marek Vasut

arm: s5p4418: dm_serial: switch to DM_SERIAL

2023-01-02T21:06:08Z

Switch the S5P4418-SOC and therefore the s5p4418_nanopi2 board to DM_SERIAL. Signed-off-by: Stefan Bosch

global: Move remaining CONFIG_SYS_NS16550_* to CFG_SYS_NS16550_*

2022-12-05T21:06:07Z

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_NS16550 namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini Reviewed-by: Simon Glass

Convert CONFIG_SYS_NS16550_MEM32 et al to Kconfig

2022-12-05T21:06:07Z

This converts the following to Kconfig: CONFIG_SPL_NS16550_MIN_FUNCTIONS CONFIG_SYS_NS16550_MEM32 CONFIG_SYS_NS16550_PORT_MAPPED CONFIG_SYS_NS16550_REG_SIZE CONFIG_SYS_NS16550_SERIAL To do this we also introduce CONFIG_SPL_SYS_NS16550_SERIAL so that platforms can enable the legacy driver here for SPL.

With the last platform for this architecture removed, remove the rest of the architecture support as well. Cc: Marek Vasut Signed-off-by: Tom Rini Reviewed-by: Simon Glass

serial: Remove obsolete CONS_INDEX_n Kconfig options

2022-05-24T00:46:06Z

These were only ever implied by sunxi platforms, and that usage has been removed. Current practice is to specify CONFIG_CONS_INDEX in each board's defconfig. Signed-off-by: Samuel Holland Reviewed-by: Tom Rini Signed-off-by: Andre Przywara
