In case the completion function failes, unbind will be called which will call cancel_work for awb_work. This will trigger a WARN message from the workqueue. To avoid this, move the INIT_WORK call at the start of the completion function. This way the work is always initialized, which corresponds to the 'always canceled' unbind code.

This will limit the incoming pixels per frame from the sensor. Currently, the ISC will stop sampling the frame only when the vsync/hsync are detected. If we misconfigure the resolution in the sensor w.r.t. resolution in the ISC, the buffer used for DMA in the ISC will be smaller than the number of pixels that the ISC DMA engine will copy. In this case it happens that the DMA will overwrite parts of the memory which should not be written, leading to memory corruption. To avoid this situation, use the PFE CFG1 and PFE CFG2 registers, which crop the incoming frame to the resolution that we configure. This way the DMA engine will never write more data than we expect it to. Signed-off-by:

Neil Armstrong authored
The Amlogic G12A SoC embeds a second CEC controller with a totally different design. The two controller can work in the same time since the CEC line can be set to two different pins on the two controllers. This second CEC controller is documented as "AO-CEC-B", thus the registers will be named "CECB_" to differentiate with the other AO-CEC driver. Unlike the other AO-CEC controller, this one takes the Oscillator clock as input and embeds a dual-divider to provide a precise 32768Hz clock for communication. This is handled by registering a clock in the driver. Unlike the other AO-CEC controller, this controller supports setting up to 15 logical addresses and supports the signal_free_time settings in the transmit function. Unfortunately, this controller does not support "monitor" mode. Signed-off-by:

The Amlogic G12A embeds a second CEC controller named AO-CEC-B, and the other one is AO-CEC-A described by the current bindings. The register interface is very close but the internal architecture is totally different. The other difference is the clock source, the AO-CEC-B takes the "oscin", the Always-On Oscillator clock, as input and embeds a dual-divider clock divider to provide the precise 32768Hz base clock for CEC communication.

Add helper function to parse the DT for the hdmi-phandle property and return the corresponding struct device pointer. It takes care to avoid increasing the device refcount since all we need is the device pointer. This pointer is used in the notifier list as a key, but it is never accessed by the CEC driver.

I previously added an RC_CORE dependency here, but missed the corner case of CONFIG_VIDEO_SECO_CEC=y with CONFIG_RC_CORE=m, which still causes a link error: drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_probe': seco-cec.c:(.text+0x1b8): undefined reference to `devm_rc_allocate_device' seco-cec.c:(.text+0x2e8): undefined reference to `devm_rc_register_device' drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_irq_handler': seco-cec.c:(.text+0xa2c): undefined reference to `rc_keydown' Refine the dependency to disallow building the RC subdriver in this case.

The timestamps in ir-keytable -t output showed that the Xbox DVD IR dongle decodes scancodes every 64ms. The last scancode of a longer button press is decodes 64ms after the last-but-one which indicates the decoder doesn't use a timeout but decodes on the last edge of the signal. 267.042629: lirc protocol(unknown): scancode = 0xace 267.042665: event type EV_MSC(0x04): scancode = 0xace 267.042665: event type EV_KEY(0x01) key_down: KEY_1(0x0002) 267.042665: event type EV_SYN(0x00). 267.106625: lirc protocol(unknown): scancode = 0xace 267.106643: event type EV_MSC(0x04): scancode = 0xace 267.106643: event type EV_SYN(0x00). 267.170623: lirc protocol(unknown): scancode = 0xace 267.170638: event type EV_MSC(0x04): scancode = 0xace 267.170638: event type EV_SYN(0x00). 267.234621: lirc protocol(unknown): scancode = 0xace 267.234636: event type EV_MSC(0x04): scancode = 0xace 267.234636: event type EV_SYN(0x00). 267.298623: lirc protocol(unknown): scancode = 0xace 267.298638: event type EV_MSC(0x04): scancode = 0xace 267.298638: event type EV_SYN(0x00). 267.543345: event type EV_KEY(0x01) key_down: KEY_1(0x0002) 267.543345: event type EV_SYN(0x00). 267.570015: event type EV_KEY(0x01) key_up: KEY_1(0x0002) 267.570015: event type EV_SYN(0x00).
