Varun Sethi 0a4081641d powerpc/mpic: FSL MPIC error interrupt support. ... All SOC device error interrupts are muxed and delivered to the core as a single MPIC error interrupt. Currently all the device drivers requiring access to device errors have to register for the MPIC error interrupt as a shared interrupt. With this patch we add interrupt demuxing capability in the mpic driver, allowing device drivers to register for their individual error interrupts. This is achieved by handling error interrupts in a cascaded fashion. MPIC error interrupt is handled by the "error_int_handler", which subsequently demuxes it using the EISR and delivers it to the respective drivers. The error interrupt capability is dependent on the MPIC EIMR register, which was introduced in FSL MPIC version 4.1 (P4080 rev2). So, error interrupt demuxing capability is dependent on the MPIC version and can be used for versions >= 4.1.
