2014-08-22[media] au0828: fix checks if dvb is initializedMauro Carvalho Chehab1-6/+6
dev->dvb is always not null, as it is an area at the dev memory. So, checking if (dev->dvb) is always true. Instead of this stupid check, what the code wants to do is to know if the DVB was successully registered. Fix it by checking, instead, for dvb->frontend. It should also be sure that this var will be NULL if the device was not properly initialized. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-22[media] au0828: add pr_info to track au0828 suspend/resume codeMauro Carvalho Chehab4-0/+17
Suspend/resume conditions can be very tricky. Add some info printk's to help tracking what's happening there. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-22[media] au0828: use pr_foo macrosMauro Carvalho Chehab8-75/+72
Instead of using printk(KERN_foo, use pr_foo() macros. No functional changes. Note: we should do the same for dprintk(), but that would require to remove the dprintk levels. So, for now, let's not touch on it. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-08-22[media] au0828: add suspend/resume code for V4L2Mauro Carvalho Chehab3-1/+67
No timers should be enabled during suspend. So, stop them. At resume time, we should do the proper initialization for it to keep working. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-22[media] au0828: properly handle stream on/off stateMauro Carvalho Chehab1-0/+3
The STREAM_ON state is used by s_format callback, but the driver never sets it. Fix it. This will also be needed in order to handle suspend/resume ops. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-22[media] au0828: Add suspend code for DVBMauro Carvalho Chehab3-1/+34
The scheduled work should be cancelled during suspend. At resume time, we need to set the frontend again. So, add such logic to the driver. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-08-22[media] au0828: don't let the IR polling thread to run at suspendMauro Carvalho Chehab1-2/+31
Trying to make au0828 to suspend can do very bad things, as the polling Kthread is not handled. We should disable it during suspend, only re-enabling it at resume. Still, analog and digital TV won't work, as we don't reinit the settings at resume, but at least it won't hang. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-08-22[media] au0828: handle IR int during suspend/resumeMauro Carvalho Chehab1-0/+6
It doesn't make sense to handle an IR code given before suspending after the device resume. So, turn off IR int while suspending. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-22[media] au0828: avoid race conditions at RC stopMauro Carvalho Chehab1-2/+2
As the RC kthread can re-enable IR int, we should first cancel the kthread and then disable IR int. While here, remove a temporary debug printk. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-08-22[media] au0828-input: Be sure that IR is enabled at pollingMauro Carvalho Chehab1-2/+10
When the DVB code sets the frontend, it disables the IR INT, probably due to some hardware bug, as there's no code there at au8522 frontend that writes on register 0xe0. Fixing it at au8522 code is hard, as it doesn't know if the IR is enabled or disabled, and just restoring the value of register 0xe0 could cause other nasty effects. So, better to add a hack at au0828-input polling interval to enable int, if disabled. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-07-30[media] au0828: improve I2C speedMauro Carvalho Chehab2-16/+27
Commits 21dc61d3c0a4 and 7a1dd50b89d4 reduced the board I2C speed to 20 MHz by default, due to a I2C stretch issue: while xc5000 uses i2c stretch when a command is sent to it, au0828 doesn't support this feature. However, this is needed only for Xceive tuners. The other I2C devices can work at the max speed. So, revert the workarounds at board level, handling it at I2C level, only when talking with xc5000.
