API call\n\nHardware Spinlock devices usually contain numerous locks (known\ndevices today support between 32 to 256 locks).\n\nOriginally hwspinlock core required drivers to register (and later,\nwhen needed, unregister) each lock separately.\n\nThat worked, but required hwspinlocks drivers to do a bit extra work\nwhen they were probed/removed.\n\nThis patch changes hwspin_lock_{un}register() to allow a bank of\nhwspinlocks to be {un}registered in a single invocation.\n\nA new \u0027struct hwspinlock_device\u0027, which contains an array of \u0027struct\nhwspinlock\u0027s is now being passed to the core upon registration (so\ninstead of wrapping each struct hwspinlock, a priv member has been added\nto allow drivers to piggyback their private data with each hwspinlock).\n\nWhile at it, several per-lock members were moved to be per-device:\n1. struct device *dev\n2. struct hwspinlock_ops *ops\n\nIn addition, now that the array of locks is handled by the core,\nthere\u0027s no reason to maintain a per-lock \u0027int id\u0027 member: the id of the\nlock anyway equals to its index in the bank\u0027s array plus the bank\u0027s\nbase_id.\nRemove this per-lock id member too, and instead use a simple pointers\narithmetic to derive it.\n\nAs a result of this change, hwspinlocks drivers are now simpler and smaller\n(about %20 code reduction) and the memory footprint of the hwspinlock\nframework is reduced.\n\nSigned-off-by: Ohad Ben-Cohen \u003cohad@wizery.com\u003e\n" }, { "commit":

achieve synchronization.\n\nTo achieve that, each physical lock must have a system-wide id number\nthat is agreed upon, otherwise remote processors can\u0027t possibly assume\nthey\u0027re using the same hardware lock.\n\nUsually boards have a single hwspinlock device, which provides several\nhwspinlocks, and in this case, they can be trivially numbered 0 to\n(num-of-locks - 1).\n\nIn case boards have several hwspinlocks devices, a different base id\nshould be used for each hwspinlock device (they can\u0027t all use 0 as\na starting id!).\n\nWhile this is certainly not common, it\u0027s just plain wrong to just\nsilently use 0 as a base id whenever the hwspinlock driver is probed.\n\nThis patch provides a hwspinlock_pdata structure, that boards can use\nto set a different base id for each of the hwspinlock devices they may\nhave, and demonstrates how to use it with the omap hwspinlock driver.\n\nWhile we\u0027re at it, make sure the hwspinlock core prints an explicit\nerror message in case an hwspinlock is registered with an id number\nthat already exists; this will help users catch such base id issues.\n\nReported-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Ohad
