serial: cpm_uart: Don't include fs_uart_pd.h when not needed

2023-08-04T13:08:55+00:00

Remove inclusion of fs_uart_pd.h from all files not using anything from that file. Signed-off-by: Christophe Leroy Link: https://lore.kernel.org/r/c7996ef4de56e7ee42a434e37d214cba337a146c.1691068700.git.christophe.leroy@csgroup.eu Signed-off-by: Greg Kroah-Hartman

Merge 6.5-rc4 into tty-next

2023-07-31T07:39:56+00:00

We need the serial/tty fixes in here as well for testing and future development. Signed-off-by: Greg Kroah-Hartman

tty: Explicitly include correct DT includes

2023-07-25T18:19:05+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Documentation: devices.txt: reconcile serial/ucc_uart minor numers

2023-07-25T17:29:23+00:00

Reconcile devices.txt with serial/ucc_uart.c regarding device number assignments. ucc_uart.c supports 4 ports and uses minor devnums 46-49, so update devices.txt with that info. Then update ucc_uart.c's reference to the location of the devices.txt list in the kernel source tree.

serial: ucc_uart: Use uart_circ_empty()

serial: Use of_property_read_bool() for boolean properties

2023-03-16T12:02:14+00:00

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool().

serial: ucc_uart: Add of_node_put() in ucc_uart_remove()

2023-01-19T14:51:09+00:00

In ucc_uart_probe(), we have added proper of_node_put() in the failure paths. However, we miss it before we free *qe_port* in the remove() function. Signed-off-by: Liang He Link: https://lore.kernel.org/r/20221205085437.1163682-1-windhl@126.com Signed-off-by: Greg Kroah-Hartman

serial: ucc_uart: Remove custom frame size calculation

2022-08-30T12:28:33+00:00

The number of bits can be calculated using tty_get_frame_size(), no need for the driver to do it on its own. Also remove a comment on number of bits that doesn't match the code nor the comment on ucc_uart_pram's rx_length ("minus 1" part differs). That comment seems a verbatim copy of that in cpm_uart/cpm_uart_core.c anyway so perhaps it was just copied over w/o much thinking.
