This patch adds driver for IR controller on MT7623 SoC. and should also work on similar Mediatek SoC. Currently testing successfully on NEC and SONY remote controller only but it should work on others (lirc, rc-5 and rc-6). Signed-off-by:

In vpfe_s_fmt(), when the sensor format and the requested format were the same, bpp was assigned to vpfe->bpp without being initialized first. Grab the bpp value that is currently used by using __vpfe_get_format() instead of its wrapper, vpfe_try_fmt(). This use of uninitialized variable has been found by compiling the kernel with clang.

The adv7604 driver platform data contains fields for configuring the drive strength of the output pins. When probing the driver through DT these fields are not explicitly initialized, which means they are left at 0. This is a reserved setting for the drive strength configuration though and can cause signal integrity issues. Whether these signal integrity issues are visible depends on the PCB specifics (e.g. the higher the load capacitance for the output the more visible the issue). But it has been observed on existing solutions at high pixel clock rates. Initialize the drive strength settings to the power-on-reset value of the device when probing through devicetree to avoid this issue.

The staging lirc_imon driver contains 4 usb ids. Two of those have a VFD and two don't. The VFD code is exactly the same in the mainline imon driver, so that part is easily ported. The staging driver produces raw IR rather than scancodes for the four devices, so I've ported the raw IR code from staging to mainline imon. Now that mainline imon can handle these four devices, lirc_imon is no longer needed. Compile tested only. Signed-off-by:

This driver is for an old mach64 VT board, which also has a framebuffer driver (atyfb) and userspace mach64 X driver. It was merged in 2010 and noone has attempted to port it to rc-core, which would be necessary to get it out of staging. I have not been able to track down the hardware either. Signed-off-by:

The lirc_parallel driver was merged in 2010 and noone has attempted to do the work necessary to get it out of staging (i.e. port it to rc-core). I have not been able to find one of these devices, and a machine with a parallel port is pretty rare too. Signed-off-by:

The ir-spi is a simple device driver which supports the connection between an IR LED and the MOSI line of an SPI device. The driver, indeed, uses the SPI framework to stream the raw data provided by userspace through an rc character device. The chardev is handled by the LIRC framework and its functionality basically provides: - write: the driver gets a pulse/space signal and translates it to a binary signal that will be streamed to the IR led through the SPI framework. - set frequency: sets the frequency whith which the data should be sent. This is handle with ioctl with the LIRC_SET_SEND_CARRIER flag (as per lirc documentation) - set duty cycle: this is also handled with ioctl with the LIRC_SET_SEND_DUTY_CYCLE flag. The driver handles duty cycles of 50%, 60%, 70%, 75%, 80% and 90%, calculated on 16bit data. The character device is created under /dev/lircX name, where X is and ID assigned by the LIRC framework. Example of usage: fd = open("/dev/lirc0", O_RDWR); if (fd < 0) return -1; val = 608000; ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val); if (ret < 0) return -1; val = 60; ret = ioctl(fd, LIRC_SET_SEND_DUTY_CYCLE, &val); if (ret < 0) return -1; n = write(fd, buffer, BUF_LEN); if (n < 0 || n != BUF_LEN) ret = -1; close(fd); Signed-off-by:Andi Shyti <andi.shyti@samsung.com> Signed-off-by:

IR raw transmitter driver type is specified in the enum rc_driver_type as RC_DRIVER_IR_RAW_TX which includes all those devices that transmit raw stream of bit to a receiver. The data are provided by userspace applications, therefore they don't need any input device allocation, but still they need to be registered as raw devices. Suggested-by:

Andi Shyti authored
The driver type can be assigned immediately when an RC device requests to the framework to allocate the device. This is an 'enum rc_driver_type' data type and specifies whether the device is a raw receiver or scancode receiver. The type will be given as parameter to the rc_allocate_device device. Change accordingly all the drivers calling rc_allocate_device() so that the device type is specified during the rc device allocation. Whenever the device type is not specified, it will be set as RC_DRIVER_SCANCODE which was the default '0' value. Suggested-by:

Add support in rc-core for drivers which implement the wakeup scancode filter by encoding the scancode using the raw IR encoders. This is by way of rc_dev::encode_wakeup which should be set to true and rc_dev::allowed_wakeup_protocols should be set to the raw IR encoders. We also do not permit the mask to be set as we cannot generate IR which would match that. Signed-off-by:

Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw events. The Manchester modulation helper is used, and for RC-5X it is used twice with two sets of timings, the first with a short trailer space for the space in the middle, and the second with no leader so that it can continue the space. The encoding in RC-5-SZ first inserts a pulse and then simply utilizes the generic Manchester encoder available in rc-core. Signed-off-by:
