clocksource/drivers/timer-of: Use unique device name instead of timer

2020-01-04T18:12:45Z

[ Upstream commit 4411464d6f8b5e5759637235a6f2b2a85c2be0f1 ] If a hardware-specific driver does not provide a name, the timer-of core falls back to device_node.name. Due to generic DT node naming policies, that name is almost always "timer", and thus doesn't identify the actual timer used. Fix this by using device_node.full_name instead, which includes the unit addrees.

clocksource/drivers/timer-of: Don't request the resource by name

2018-01-08T16:57:24Z

When the driver does not specify a name for the resource, don't use of_io_request_and_map() but of_iomap(). That prevents resource name allocation conflicts on some platforms which have the same name as the node.

clocksource/drivers/timer-of: Store the device node pointer in 'struct timer_of'

2018-01-08T16:57:24Z

Under certain circumstances, some specific operations must be done with the device node pointer, which forces the timer code to propagate the pointer to the functions which need it. In order to consolidate the function signatures in the different drivers by using the timer-of structure, let's store it in the timer-of structure as a handy pointer when it is needed.

clocksource/drivers/timer-of: Add kernel documentation

The current code has no comments, neither any function descriptions. Fix this by adding function descriptions in kernel doc format.

clocksource/drivers/timer-of: Fix function names

All the functions are not prefixed with 'timer_of_', fix the naming in order to have the code consistent.

clocksource/timer_of: Rename timer_of_exit to timer_of_cleanup

2017-11-14T10:20:24Z

Change the function name to something more explicit since it is only used in init error cases. Add __init annotation and description about the function usage.

clocksource: Convert to using %pOF instead of full_name

2017-08-31T13:56:17Z

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node.

clocksource/drivers/timer-of: Checking for IS_ERR() instead of NULL

2017-08-11T10:53:21Z

The current code checks the return value of the of_io_request_and_map() function as it was returning a NULL pointer in case of error. However, it returns an error code encoded in the pointer return value, not a NULL value. Fix this by checking the returned pointer against IS_ERR() and return the error with PTR_ERR().
