Device naming when multiple boards are installed ———————————————— Naming convention for each multiport board is pre-defined as below, assuming 2 8-port boards, 1 4-port board and 1 2-port board. Also there are other lines connected to the device reset etc. Would it be possible to change the driver, add custom ioctl so it can change to synchronous mode and use this only from my custom device driver? Quote Thu Jun 25, 2: Questions Tags Users Badges Unanswered. For an SPI connection, then yes, you would have to write a new device driver. But if I was doing the development, then this char driver would just emulate a tty so that existing kernel interfaces could be reused.

Linux kernel: Serial subsystem(UART)
From context it sounds like a slave. What would be the consequences?
PCI UART Driver Install Guide for Linux Kernel 2.4.x
In this example, on a raspberry pi linux kernel uart, perhaps you want btbcm? The resource that the kernel can control is the onboard USART, not the offboard “custom device” which could be disconnected or attached to another port. Any datasheet or link to it? The catch is that usually such drivers do not create a linux kernel uart i. Would it be possible to change the driver, add custom ioctl so it can change to synchronous mode and use this only from my custom device driver?
I’m trying to detect what driver is responsible for providing the HCI interface for the Raspberry Pi 3 Bluetooth module.

Do you want a character device? XX is the version of the driver package.

linux kernel uart I have custom device attached to UART and would like to implement own driver. Quote Thu Jun 25, 2: Is using serio for a non-input device that bad? This is accomplished in one of two ways. There is some extra work involved to maintain data encapsulation and interface integrity.
