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.

tty: serial: Fix refcount leak bug in ucc_uart.c

2022-06-27T12:36:07+00:00

In soc_info(), of_find_node_by_type() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore.

firmware: replace HOTPLUG with UEVENT in FW_ACTION defines

2021-05-13T14:14:45+00:00

With commit 312c004d36ce ("[PATCH] driver core: replace "hotplug" by "uevent"") already in the tree over a decade, update the name of FW_ACTION defines to follow semantics, and reflect what the defines are really meant for, i.e. whether or not generate user space event.

tty: serial: ucc_uart: replace qe_io{read,write}* wrappers by generic io{read,write}*

2021-04-06T20:40:42+00:00

Commit 6ac9b61786cc ("soc: fsl: qe: introduce qe_io{read,write}* wrappers") added specific I/O accessors for qe because at that time ioread/iowrite functions were sub-optimal on powerpc/32 compared to the architecture specific in_/out_ IO accessors. But as ioread/iowrite accessors are now equivalent since commit 894fa235eb4c ("powerpc: inline iomap accessors"), use them in order to allow removal of the qe specific ones.
