remoteproc: ingenic: Request IRQ disabled The ingenic remoteproc driver requests its IRQ and then immediately disables it. The disable is necessary since irq_request() normally enables the IRQ. But there is a new flag IRQF_NO_AUTOEN that when specified keeps the IRQ disabled. Use this new flag rather than calling disable_irq(). This slightly reduce the boilerplate code and also avoids a theoretical race condition where the IRQ could fire between irq_request() and disable_irq().

remoteproc: add is_iomem to da_to_va Introduce an extra parameter is_iomem to da_to_va, then the caller could take the memory as normal memory or io mapped memory.

remoteproc: ingenic: Add module parameter 'auto_boot' Add a 'auto_boot' module parameter that instructs the remoteproc driver whether or not it should auto-boot the remote processor, which will default to "false", since the VPU in Ingenic SoCs does not really have any predetermined function.

remoteproc: ingenic: Constify ingenic_rproc_ops The only usage of ingenic_rproc_ops is to pass its address to devm_rproc_alloc(), which accepts a const pointer. Make it const to allow the compiler to put it in read-only memory.

remoteproc: ingenic: Move clock handling to prepare/unprepare callbacks This patch moves clock related operations to the remoteproc prepare() and unprepare() callbacks so that the PM runtime framework doesn't have to be involved needlessly. This provides a simpler approach and requires less code.
