The iMX6ULL UART5_RX_DATA_SELECT_INPUT DAISY Register has some different bit definitions to that same register in the iMX6UL. The bits for the iMX6UL: 000 CSI_DATA00_ALT8 — Selecting Pad: CSI_DATA00 for Mode: ALT8 001 CSI_DATA01_ALT8 — Selecting Pad: CSI_DATA01 for Mode: ALT8 010 GPIO1_IO04_ALT8 — Selecting Pad: GPIO1_IO04 for Mode: ALT8 011 GPIO1_IO05_ALT8 — Selecting Pad: GPIO1_IO05 for Mode: ALT 100 UART5_TX_DATA_ALT0 — Selecting Pad: UART5_TX_DATA for Mode: ALT 101 UART5_RX_DATA_ALT0 — Selecting Pad: UART5_RX_DATA for Mode: ALT But for the iMX6ULL: 000 CSI_DATA00_ALT8 — Selecting Pad: CSI_DATA00 for Mode: ALT8 001 CSI_DATA01_ALT8 — Selecting Pad: CSI_DATA01 for Mode: ALT8 010 GPIO1_IO04_ALT8 — Selecting Pad: GPIO1_IO04 for Mode: ALT8 011 GPIO1_IO05_ALT8 — Selecting Pad: GPIO1_IO05 for Mode: ALT 100 UART1_TX_DATA_ALT9 — Selecting Pad: UART1_TX_DATA for Mode: ALT9 101 UART1_RX_DATA_ALT9 — Selecting Pad: UART1_RX_DATA for Mode: ALT9 110 UART5_TX_DATA_ALT0 — Selecting Pad: UART5_TX_DATA for Mode: ALT0 111 UART5_RX_DATA_ALT0 — Selecting Pad: UART5_RX_DATA for Mode: ALT0 Specifically for a board I am working on with the serial console on UART5 I need to be able to enable UART5_RX_DATA_ALT0 mode. There is no definition for the iMX6ULL version of that in imx6ul-pinfunc.h or imx6ull-pinfunc.h. Add definitions for the missing UART5 input select register bits of the iMX6ULL.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
