2009-04-21fsl_rio: Pass the proper device to dma mapping routinesAnton Vorontsov
The driver should pass a device that specifies internal DMA ops, but currently NULL pointer is passed, therefore following bug appears during boot up: ------------[ cut here ]------------ Kernel BUG at c0018a7c [verbose debug info unavailable] Oops: Exception in kernel mode, sig: 5 [#1] [...] NIP [c0018a7c] fsl_rio_doorbell_init+0x34/0x60 LR [c0018a70] fsl_rio_doorbell_init+0x28/0x60 Call Trace: [ef82bda0] [c0018a70] fsl_rio_doorbell_init+0x28/0x60 (unreliable) [ef82bdc0] [c0019160] fsl_rio_setup+0x6b8/0x84c [ef82be20] [c02d28ac] fsl_of_rio_rpn_probe+0x30/0x50 [ef82be40] [c0234f20] of_platform_device_probe+0x5c/0x84 [...] ---[ end trace 561bb236c800851f ]--- This patch fixes the issue.

2008-04-29[RAPIDIO] Add RapidIO multi mport supportZhang Wei
The original RapidIO driver suppose there is only one mpc85xx RIO controller in system. So, some data structures are defined as mpc85xx_rio global, such as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's private members. And you can define multi RIO OF-nodes in dts file for multi RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in Freescale's silicon. And the mport operation function declaration should be changed to know which RapidIO controller is target.
