int ipu_irq_attach_irq	(	struct ipu *	ipu,

Definition at line 356 of file ipu_irq.c.

Definition at line 398 of file ipu_irq.c.

int ipu_irq_map ( unsigned int source )

ipu_irq_map() - map an IPU interrupt source to an IRQ number : interrupt source bit position (see below)

Returns: : mapped IRQ number or negative error code

The source parameter has to be explained further. On i.MX31 IPU has 137 IRQ sources, they are broken down in 5 32-bit registers, like 32, 32, 24, 32, 17. However, the source argument of this function is not the sequence number of the possible IRQ, but rather its bit position. So, first interrupt in fourth register has source number 96, and not 88. This makes calculations easier, and also provides forward compatibility with any future IPU implementations with any interrupt bit assignments.

Definition at line 198 of file ipu_irq.c.

bool ipu_irq_status ( unsigned int irq )

ipu_irq_status() - returns the current interrupt status of the specified IRQ. : interrupt line to get status for.

Returns: : true if the interrupt is pending/asserted or false if the interrupt is not pending.

Definition at line 169 of file ipu_irq.c.

int ipu_irq_unmap ( unsigned int source )

ipu_irq_map() - map an IPU interrupt source to an IRQ number : interrupt source bit position (see ipu_irq_map())

Returns: : 0 or negative error code
