Biju <biju.das.au@gmail.com> says: From: Biju Das <biju.das.jz@bp.renesas.com> The calculation formula for nominal bit rate of classical CAN is same as that of nominal bit rate of CANFD on the RZ/G3E SoC and R-Car Gen4 compared to other SoCs. Update the nominal bit rate constants. Apart from this, for replacing function-like macros, introduced rcar_canfd_compute_{nominal,data}_bit_rate_cfg(). v2->v3: * Replaced "shared_bittiming"->"shared_can_regs" as it is same for RZ/G3E and R-Car Gen4. * Updated commit header and description for patch#1. * Added Rb tag from Geert for patch #2,#3 and #4. * Dropped _MASK suffix from RCANFD_CFG_* macros. * Dropped _MASK suffix from RCANFD_NCFG_NBRP_MASK macro. * Dropped _MASK suffix from the macro RCANFD_DCFG_DBRP_MASK. * Followed the order as used in struct can_bittiming{_const} for easy maintenance. v1->v2: * Dropped patch#2 as it is accepted. * Moved patch#4 to patch#2. * Updated commit header and description for patch#2. * Kept RCANFD_CFG* macro definitions to give a meaning to the magic number using GENMASK macro and used FIELD_PREP to extract value. * Split patch#3 for computing nominal and data bit rate config separate. * Updated rcar_canfd_compute_nominal_bit_rate_cfg() to handle nominal bit rate configuration for both classical CAN and CANFD. * Replaced RCANFD_NCFG_NBRP->RCANFD_NCFG_NBRP_MASK and used FIELD_PREP to extract value. * Replaced RCANFD_DCFG_DBRP->RCANFD_DCFG_DBRP_MASK and used FIELD_PREP to extract value.

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 reStructuredText 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.
