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.

test: serial: Add test for putc/puts

2022-04-14T19:39:15Z

This adds a test to ensure that puts is equivalent to putc called in a loop. We don't verify the contents of the message to avoid having to record console output a second time (though that could be added in the future). The globals are initialized to non-zero values to avoid a warning; in particular, the character count is off-by-one (but we always make relative measurements).

dm: Rename DM test flags to make them more generic

2020-08-08T02:31:32Z

The test flags used by driver model are currently not available to other tests. Rather than creating two sets of flags, make these flags generic by changing the DM_ prefix to UT_ and moving them to the test.h header. This will allow adding other test flags without confusion.

dm: core: Drop header files from dm/test.h

2020-08-04T02:19:54Z

These header file should not be included in other header files. Remove them and add to each individual file. Add test/test.h to test/ui.h since that is a reasonable place. Signed-off-by: Simon Glass

dm: serial: Add clock member to struct serial_device_info

2020-04-16T06:36:28Z

Some callers of serial_getinfo() would like to know the UART base clock speed in order to make decision what to pass to OS in some cases. In particular, ACPI SPCR table expects only certain base clock speed and thus we have to act accordingly. Signed-off-by: Andy Shevchenko Reviewed-by: Simon Glass Reviewed-by: Bin Meng
