Fabio Estevam 9ea2c02baf dma: imx-dma: Fix kernel crash due to missing clock conversion ... commit a2367db2ec upstream. With the new i.MX clock infrastructure we need to request the dma clocks seperately: ahb and ipg clocks. This fixes the following kernel crash and make audio to be functional again: root@freescale /home$ aplay audio48k16S.wav Playing WAVE 'audio48k16S.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = c7b74000 [00000000] *pgd=a7bb5831, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] PREEMPT ARM Modules linked in: CPU: 0 Not tainted (3.5.0-rc5-next-20120702-00007-g3028b64 #1128) PC is at snd_dmaengine_pcm_get_chan+0x8/0x10 LR is at snd_imx_pcm_hw_params+0x18/0xdc pc : [<c02d3cf8>] lr : [<c02e95ec>] psr: a0000013 sp : c7b45e30 ip : ffffffff fp : c7ae58e0 r10: 00000000 r9 : c7ae981c r8 : c7b88800 r7 : c7ae5a60 r6 : c7ae5b20 r5 : c7ae9810 r4 : c7afa060 r3 : 00000000 r2 : 00000001 r1 : c7b88800 r0 : c7afa060 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 0005317f Table: a7b74000 DAC: 00000015 Process aplay (pid: 701, stack limit = 0xc7b44270) Stack: (0xc7b45e30 to 0xc7b46000) 5e20: 00100000 00000029 c7b88800 c02db870 5e40: c7ae5a60 c02d4594 00000010 01ae5a60 c7ae5a60 c7ae9810 c7ae9810 c7afa060 5e60: c7ae5b20 c7ae5a60 c7b88800 c02e3ef0 c02e3e08 c7b1e400 c7afa060 c7b88800 5e80: 00000000 c0014da8 c7b44000 00000000 bec566ac c02cd400 c7afa060 c7afa060 5ea0: bec56800 c7b88800 c0014da8 c02cdd7c c04ee710 c04ee7b8 00000003 c005fc74 5ec0: 00000000 7fffffff c7b45f00 c7afa060 c7b67420 c7ba3070 00000004 c0014da8 5ee0: c7b44000 00000000 bec566ac c02ced88 c04e95f8 b6f5ab04 c7b45fb0 0145a468 5f00: 0145a600 bec566bc bec56800 c7b67420 c7ba3070 c00d499c c7b45f18 c7b45f18 5f20: 0000001a 00000004 00000001 c7b44000 c0527f40 00000009 00000008 00000000 5f40: c7b44000 c002c9ec 00000001 c04f0ab0 c04ebec0 00000101 00000000 0000000a 5f60: 60000093 c7b67420 bec56800 c25c4111 00000004 c0014da8 c7b44000 00000000 5f80: bec566ac c00d4f38 b6ffb658 00000000 c0522d80 0145a468 b6fd5000 0145a418 5fa0: 00000036 c0014c00 0145a468 b6fd5000 00000004 c25c4111 bec56800 00020001 5fc0: 0145a468 b6fd5000 0145a418 00000036 0145a468 0145a600 bec566bc bec566ac 5fe0: 0145a468 bec56388 b6f65ce4 b6dcebec 20000010 00000004 00000000 00000000 [<c02d3cf8>] (snd_dmaengine_pcm_get_chan+0x8/0x10) from [<c02e95ec>] (snd_imx_pcm_hw_params+0x18/0xdc) [<c02e95ec>] (snd_imx_pcm_hw_params+0x18/0xdc) from [<c02e3ef0>] (soc_pcm_hw_params+0xe8/0x1f0) [<c02e3ef0>] (soc_pcm_hw_params+0xe8/0x1f0) from [<c02cd400>] (snd_pcm_hw_params+0x124/0x474) [<c02cd400>] (snd_pcm_hw_params+0x124/0x474) from [<c02cdd7c>] (snd_pcm_common_ioctl1+0x4b4/0xf74) [<c02cdd7c>] (snd_pcm_common_ioctl1+0x4b4/0xf74) from [<c02ced88>] (snd_pcm_playback_ioctl1+0x30/0x510) [<c02ced88>] (snd_pcm_playback_ioctl1+0x30/0x510) from [<c00d499c>] (do_vfs_ioctl+0x80/0x5e4) [<c00d499c>] (do_vfs_ioctl+0x80/0x5e4) from [<c00d4f38>] (sys_ioctl+0x38/0x60) [<c00d4f38>] (sys_ioctl+0x38/0x60) from [<c0014c00>] (ret_fast_syscall+0x0/0x2c) Code: e593000c e12fff1e e59030a0 e59330bc (e5930000) ---[ end trace fa518c8ba3a74e97 ]-- Reported-by: Javier Martin <javier.martin@vista-silicon.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2012-08-26 15:00:39 -07:00
