mainlining shenanigans
9ed63c60c9
The flexcan IP core has up to 64 mailboxes, each one has a corresponding interrupt bit in the iflag1 or iflag2 registers and a mask bit in the imask1 or imask2 registers. In the timestamp (i.e. non FIFO) mode the driver needs to mask out all non RX interrupt sources and uses the precomputed values rx_mask1 and rx_mask2 of struct flexcan_priv for this. Currently these values cannot be used directly, as they contain the TX mailbox flag. This patch removes the TX flag from flexcan_priv::rx_mask1 and flexcan_priv::rx_mask2, and sets the TX flag directly when writing the regs->iflag1 and regs->iflag2 into the hardware.

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. 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.
