The GPIO controller of MPC512x is slightly different from 8xxx GPIO controllers. The register interface is the same except the external interrupt control register. The MPC512x GPIO controller differentiates between four interrupt event types and therefore provides two interrupt control registers, GPICR1 and GPICR2. GPIO[0:15] interrupt event types are configured in GPICR1 register, GPIO[16:31] - in GPICR2 register. This patch adds MPC512x speciffic set_type() callback and updates config file and comments. Additionally the gpio chip registration function is changed to use for_each_matching_node() preventing multiple registration if a node claimes compatibility with another gpio controller type.

More code can be pushed from rwsem_down_read_failed and rwsem_down_write_failed into rwsem_down_failed_common. Following change adding down_read_critical infrastructure support also enjoys having flags available in a register rather than having to fish it out in the struct rwsem_waiter... Signed-off-by:

This change addresses the following situation: - Thread A acquires the rwsem for read - Thread B tries to acquire the rwsem for write, notices there is already an active owner for the rwsem. - Thread C tries to acquire the rwsem for read, notices that thread B already tried to acquire it. - Thread C grabs the spinlock and queues itself on the wait queue. - Thread B grabs the spinlock and queues itself behind C. At this point A is the only remaining active owner on the rwsem. In this situation thread B could notice that it was the last active writer on the rwsem, and decide to wake C to let it proceed in parallel with A since they both only want the rwsem for read.

Previously each waiting thread added a bias of RWSEM_WAITING_BIAS. With this change, the bias is added only once to indicate that the wait list is non-empty. This has a few nice properties which will be used in following changes: - when the spinlock is held and the waiter list is known to be non-empty, count < RWSEM_WAITING_BIAS <=> there is an active writer on that sem - count == RWSEM_WAITING_BIAS <=> there are waiting threads and no active readers/writers on that sem Signed-off-by: -
Michel Lespinasse authored
In __rwsem_do_wake(), we can skip the active count check unless we come there from up_xxxx(). Also when checking the active count, it is not actually necessary to increment it; this allows us to get rid of the read side undo code and simplify the calculation of the final rwsem count adjustment once we've counted the reader threads to wake. The basic observation is the following. When there are waiter threads on a rwsem and the spinlock is held, other threads can only increment the active count by trying to grab the rwsem in down_xxxx(). However down_xxxx() will notice there are waiter threads and take the down_failed path, blocking to acquire the spinlock on the way there. Therefore, a thread observing an active count of zero with waiters queued and the spinlock held, is protected against other threads acquiring the rwsem until it wakes the last waiter or releases the spinlock.

Michel Lespinasse authored
This is in preparation for later changes in the series. In __rwsem_do_wake(), the first queued waiter is checked first in order to determine whether it's a writer or a reader. The code paths diverge at this point. The code that checks and increments the rwsem active count is duplicated on both sides - the point is that later changes in the series will be able to independently modify both sides. Signed-off-by:

Allow device probing to recognise the Fintek F71808E. Sysfs interface: * Fan/pwm control is the same as for F71889FG * Temperature and voltage sensor handling is largely the same as for the F71889FG - Has one temperature sensor less (doesn't have temp3) - Misses one voltage sensor (doesn't have V6, thus in6_input refers to what in7_input refers for F71889FG) For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up such that it can largely be reused.

These are caused by checkpatch incorrectly parsing its internal representation of a statement block for struct's (or anything else that is a statement block encapsulated in {}'s that also ends with a ';').
