* media: rc: nuvoton: remove rudimentary transmit functionalityHeiner Kallweit2017-08-201-24/+0
| | | | | | | | | | | | | | | | | | | | | Transmit support in this driver was never tested and based on the code it can't work. Just one example: The buffer provided to nvt_tx_ir holds unsigned int values in micro seconds: First value is for a pulse, second for a pause, etc. Bytes in this buffer are copied as-is to the chip FIFO what can't work as the chip-internal format is totally different. See also conversion done in nvt_process_rx_ir_data. Even if we would try to fix this we have the issue that we can't test it. There seems to be no device on the market using IR transmit with one of the chips supported by this driver. To facilitate maintenance of the driver I'd propose to remove the rudimentary transmit support.

* [media] media: rc: nuvoton: rename spinlock nvt_lockHeiner Kallweit2016-11-181-1/+1
| | | | | | | | | | | Spinlock nvt_lock is a member of struct nvt_dev and there's no need to prefix it with nvt_. So remove this prefix.

| | | | | | | | | | Using a separate spinlock to protect access to substruct tx of struct nvt_dev doesn't provide any actual benefit. We can use spinlock nvt_lock to protect all access to struct nvt_dev and get rid of nvt->tx.lock.

* [media] media: rc: nuvoton: eliminate member pdev from struct nvt_devHeiner Kallweit2016-11-181-1/+0
| | | | | | | | | | | | Member pdev of struct nvt_dev is needed only to access &pdev->dev. We can get rid of this it by using rdev->dev.parent instead (both point to the same struct device). Setting rdev->dev.parent can be removed from the probe function as this is done by devm_rc_allocate_device now.

* [media] media: rc: nuvoton: remove interrupt handling for wakeupHeiner Kallweit2016-07-081-1/+0
| | | | | | | | | | | | There is a rudimentary ISR for handling interrupts generated by the wakeup part of the chip. Interrupts however have never been enabled in the wakeup part. Also, now that we can set the wakeup sequence via sysfs, there's in general no need to enable interrupts in the wakeup part.

* [media] media: rc: nuvoton: support reading / writing wakeup sequence via sysfsHeiner Kallweit2016-03-031-0/+3
| | | | | | | | | | | | | | | | | This patch adds a binary attribute /sys/class/rc/rc?/wakeup_data which allows to read / write the wakeup sequence. In combination with the core extension for exposing the most recent raw packet this allows to easily define and set a wakeup sequence. At least on my Zotac CI321 the BIOS resets the wakeup sequence at each boot to a factory default. Therefore I use a udev rule SUBSYSTEM=="rc", DRIVERS=="nuvoton-cir", ACTION=="add", RUN+="<script>" with the script basically doing cat <stored wakeup sequence> >/sys${DEVPATH}/wakeup_data Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] nuvoton-cir: Don't touch PS/2 interrupts while initializingAntti Seppälä2014-02-041-1/+0
| | | | | | | | | | | | | | | | | | | | | | There are reports[1] that on some motherboards loading the nuvoton-cir disables PS/2 keyboard input. This is caused by an erroneous write of CIR_INTR_MOUSE_IRQ_BIT to ACPI control register. According to datasheet the write enables mouse power management event interrupts which will probably have ill effects if the motherboard has only one PS/2 port with keyboard in it. The cir hardware does not need mouse interrupts to function and should not touch them. This patch removes the illegal writes and registry definitions.

* [media] nuvoton-cir: simplify raw IR sample handlingJarod Wilson2011-09-111-1/+0
| | | | | | | | | | | | | | | | | The nuvoton-cir driver was storing up consecutive pulse-pulse and space-space samples internally, for no good reason, since ir_raw_event_store_with_filter() already merges back to back like samples types for us. This should also fix a regression introduced late in 3.0 that related to a timeout change, which actually becomes correct when coupled with this change. Tested with RC6 and RC5 on my own nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky behavior in 3.0 due to the timeout change.

| | | | | | | | | | | | | Thanks to some excellent investigative work by Douglas Clowes, it was uncovered that the older w83667hg Nuvoton chip functions with this driver after actually enabling the CIR function via its multi-function chip config register. The CIR and CIR wide-band sensor enable bits are just in a different place on this hardware, so we only poke register 0x27 on 677 hardware now, and we poke register 0x2c on the 667 now.

* [media] ir-core: make struct rc_dev the primary interfaceDavid Härdeman2010-12-291-2/+1
| | | | | | | | | | | | | | | | | | | | | | This patch merges the ir_input_dev and ir_dev_props structs into a single struct called rc_dev. The drivers and various functions in rc-core used by the drivers are also changed to use rc_dev as the primary interface when dealing with rc-core. This means that the input_dev is abstracted away from the drivers which is necessary if we ever want to support multiple input devs per rc device. The new API is similar to what the input subsystem uses, i.e: rc_device_alloc() rc_device_free() rc_device_register() rc_device_unregister() [mchehab@redhat.com: Fix compilation on mceusb and cx231xx, due to merge conflicts] Signed-off-by: David Härdeman <david@hardeman.nu> Acked-by: Jarod Wilson <jarod@redhat.com> Tested-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
