serdev: Replace custom code with device_match_acpi_handle()

2023-10-27T11:04:11Z

Since driver core provides a generic device_match_acpi_handle() we may replace the custom code with it. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20231024124115.3598090-4-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

serdev: Simplify devm_serdev_device_open() function

2023-10-27T11:04:11Z

Use devm_add_action_or_reset() instead of devres_alloc() and devres_add(), which works the same. This will simplify the code. There is no functional changes.

serdev: Make use of device_set_node()

2023-10-27T11:04:11Z

Use device_set_node() instead of assigning ctrl->dev.of_node directly because it also sets the firmware node. Signed-off-by: Andy Shevchenko Link: https://lore.kernel.org/r/20231024124115.3598090-2-andriy.shevchenko@linux.intel.com Signed-off-by: Greg Kroah-Hartman

tty: make counts in tty_port_client_operations hooks size_t

2023-08-11T19:12:44Z

The counts in tty_port_client_operations hooks' are currently represented by all 'int', 'unsigned int', and 'size_t'. Unify them all to unsigned 'size_t' for clarity. Note that size_t is used already in tty_buffer.c. So, eventually, it is spread for counts everywhere and this is the beginning. So the two changes namely: * ::receive_buf() is called from tty_ldisc_receive_buf(). And that expects values ">= 0" from ::receive_buf(), so switch its rettype to size_t is fine. tty_ldisc_receive_buf() types will be changed separately. * ::lookahead_buf()'s count comes from lookahead_bufs() and is already 'unsigned int'.

tty: make tty_port_client_operations operate with u8

2023-08-11T19:12:44Z

The parameters are already unsigned chars. So make them explicitly u8s, as the rest is going to be unified to u8 eventually too. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Rob Herring Link: https://lore.kernel.org/r/20230810091510.13006-10-jirislaby@kernel.org Signed-off-by: Greg Kroah-Hartman

serdev: Add method to assert break signal over tty UART port

2023-04-24T04:51:25Z

Adds serdev_device_break_ctl() and an implementation for ttyport. This function simply calls the break_ctl in tty layer, which can assert a break signal over UART-TX line, if the tty and the underlying platform and UART peripheral supports this operation.

serdev: Replace all instances of ENOTSUPP with EOPNOTSUPP

2023-04-24T04:51:11Z

This replaces all instances of ENOTSUPP with EOPNOTSUPP since ENOTSUPP is not a standard error code. This will help maintain consistency in error codes when new serdev API's are added. Signed-off-by: Neeraj Sanjay Kale Reviewed-by: Simon Horman Signed-off-by: Luiz Augusto von Dentz

driver core: make struct device_type.uevent() take a const *

2023-01-27T12:45:36Z

The uevent() callback in struct device_type should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.
