Tomi Valkeinen 6da9f89172 drm/omap: fix (un)registering irqs inside an irq handler ... omapdrm (un)registers irqs inside an irq handler. The problem is that the (un)register function uses dispc_runtime_get/put() to enable the clocks, and those functions are not irq safe by default. This was kind of fixed in 48664b21ae (OMAPDSS: DISPC: set irq_safe for runtime PM), which makes dispc's runtime calls irq-safe. However, using pm_runtime_irq_safe in dispc makes the parent of dispc, dss, always enabled, effectively preventing PM for the whole DSS module. This patch makes omapdrm behave better by adding new irq (un)register functions that do not use dispc_runtime_get/put, and using those functions in interrupt context. Thus we can make dispc again non-irq-safe, allowing proper PM. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Rob Clark <robdclark@gmail.com>		2014-01-09 15:15:24 +02:00
