2009-01-09libata: Add 32bit PIO supportAlan Cox6-9/+63
This matters for some controllers and in one or two cases almost doubles PIO performance. Add a bmdma32 operations set we can inherit and activate it for some controllers Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-01-09[libata] ahci: Withdraw IGN_SERR_INTERNAL for SB800 SATAShane Huang1-2/+6
There is an issue in ATI SB600/SB700 SATA that PxSERR.E should not be set on some conditions, which will lead to many SATA ODD error messages. commit 55a61604cd1354e1783364e1c901034f2f474b7d is the workaround. Since SB800 fixed this HW issue, IGN_SERR_INTERNAL should be withdrawn for SB800. Signed-off-by: Shane Huang <shane.huang@amd.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-01-09pata_hpt366: reimplement mode programmingTejun Heo1-65/+44
Reimplement mode programming logic of pata_hpt366 such that it's identical to that of IDE hpt366 driver. The differences were... * pata_hpt366 used 0xCFFF8FFFF to mask pio modes and 0x3FFFFFFF dma modes. IDE hpt366 uses 0xC1F8FFFF for PIO, 0x303800FF for MWDMA and 0x30070000 for UDMA. * pata_hpt366 doesn't set 0x08000000 for PIO unless it's already set and always turns it on for MWDMA/UDMA. IDE hpt366 doesn't bother with the bit. It always uses what was there. * IDE hpt366 always clears 0xC0000000. pata_hpt366 doesn't.

2009-01-09ata_piix: save, use saved and restore IOCFGTejun Heo1-15/+34
Certain ACPI implementations mess up IOCFG on _STM making libata detect cable type incorrectly after a suspend/resume cycle. This patch makes ata_piix save IOCFG on attach, use the saved value for things which aren't dynamic and restore it on detach so that the next driver also gets the BIOS initialized value. This patch contains the following changes. * makes ich_pata_cable_detect() use saved_iocfg. * make piix_iocfg_bit18_quirk() take @host and use saved_iocfg. * hpriv allocation moved upwards to save iocfg before doing anything else. This fixes bz#11879. Andreas Mohr reported and diagnosed the problem. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Andreas Mohr <andi@lisas.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2009-01-08w1: allow master IO commandsEvgeniy Polyakov1-65/+77
This small patchset extendes existing commands with reset, master IO and status messages. Reset is used to reset the bus for given master device, master IO command allows to initiate IO against bus itself not selecting slave device first, which can be used to probe the device for example. And status messages carry command completion status back to the userspace (namely very useful to get -ENODEV from when requested device was not found). Great thanks to Paul Alfille of OWFS for testing and commands suggestions. This patch: Allow starting of IO not against already found slave devices, but against the bus itself, which can be used for example to probe devices.

2009-01-08V4L/DVB (10190): cx88: Fix some Kbuild troublesMauro Carvalho Chehab6-47/+65
As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues: drivers/built-in.o: In function `cx88_call_i2c_clients': (.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend' drivers/built-in.o: In function `cx8802_probe': cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend' cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends' With those configs: CONFIG_VIDEO_CX88=y CONFIG_VIDEO_CX88_BLACKBIRD=y CONFIG_VIDEO_CX88_DVB=m CONFIG_DVB_CORE=m After carefully examining the code, with the current code, several cx88 drivers (cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module, if one of them is marked as such. Just fixing Kconfig could create a very complex set of rules. Also, this hides a problem with the current approach where the dvb functionality weren't confined inside dvb module. What happens is that: - cx88-i2c (part of cx8800) has some special rules if DVB; - cx88-mpeg (cx8802 module) has also part of DVB init code; - cx88-dvb has the rest of the dvb code; - cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not. So, instead of doing some tricks at Kconfig and wait for a next breakage, this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb. Another problem is that cx8802 were being compiled, even without cx88-dvb and cx88-blackbird modules. While on this code, let's fix also a reported problem: http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html A solution for the issue were proposed here: http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect and solve the issues.

As reported by Randy Dunlap <randy.dunlap@oracle.com>: With CONFIG_INPUT=m and CONFIG_DVB_DM1105=y: drivers/built-in.o: In function `input_sync': dm1105.c:(.text+0x120c33): undefined reference to `input_event' drivers/built-in.o: In function `dm1105_emit_key': dm1105.c:(.text+0x120c6c): undefined reference to `input_event' dm1105.c:(.text+0x120c82): undefined reference to `input_event' dm1105.c:(.text+0x120cb2): undefined reference to `input_event' dm1105.c:(.text+0x120cd1): undefined reference to `input_event' drivers/built-in.o: In function `dm1105_ir_init': (.devinit.text+0xd8ae): undefined reference to `input_allocate_device' drivers/built-in.o: In function `dm1105_ir_init': (.devinit.text+0xd9f6): undefined reference to `input_register_device' drivers/built-in.o: In function `dm1105_ir_init': (.devinit.text+0xda09): undefined reference to `input_free_device' drivers/built-in.o: In function `dm1105_ir_exit': (.devexit.text+0xcde): undefined reference to `input_unregister_device' This is due to the lack of a dependency between dm1105 and CONFIG_INPUT Cc: Igor M.

2009-01-08V4L/DVB (10185): Use negated usb_endpoint_xfer_control, etcJulia Lawall5-7/+5
This patch extends 134179823b3ca9c8b98e0631906459dbb022ff9b by using usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk, and usb_endpoint_xfer_int in the negated case as well. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_CONTROL\|0\)) + !usb_endpoint_xfer_control(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_ISOC\|1\)) + !usb_endpoint_xfer_isoc(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_BULK\|2\)) + !usb_endpoint_xfer_bulk(epd) @@ struct usb_endpoint_descriptor *epd; @@ - (usb_endpoint_type(epd) != \(USB_ENDPOINT_XFER_INT\|3\)) + !usb_endpoint_xfer_int(epd) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-01-08V4L/DVB (10182): tda8290: fix TDA8290 + TDA18271 initializationMichael Krufky1-1/+2
Don't call tda8290_init_tuner unless we have either a TDA8275 or TDA8275A present. Calling this function will cause a TDA18271 to get sick, so we should only call it when needed. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
