2015-06-12hwspinlock: add a CSR atlas7 driverWei Chen
Add hwspinlock support for the CSR atlas7 SoC. The Hardware Spinlock device on atlas7 provides hardware assistance for synchronization between the multiple processors in the system (dual Cortex-A7, CAN bus Cortex-M3 and audio DSP).

2011-02-17drivers: hwspinlock: add OMAP implementationSimon Que
Add hwspinlock support for the OMAP4 Hardware Spinlock device. The Hardware Spinlock device on OMAP4 provides hardware assistance for synchronization between the multiple processors in the system (dual Cortex-A9, dual Cortex-M3 and a C64x+ DSP).

2011-02-17drivers: hwspinlock: add frameworkOhad Ben-Cohen
Add a platform-independent hwspinlock framework. Hardware spinlock devices are needed, e.g., in order to access data that is shared between remote processors, that otherwise have no alternative mechanism to accomplish synchronization and mutual exclusion operations.
