Hello David,

this is a pull request for net-next/master consisting of 32 patches.

The first patch is by Gustavo A. R. Silva and removes unused code in the
generic CAN infrastructure.

The next three patches target the mcp251x driver. The one by Andy
Shevchenko removes the legacy platform data support from the driver. The
other two are by Timo Schlüßler and reset the device only when needed,
to prevent glitches on the output when GPIO support is added.

I'm contributing two patches fixing checkpatch warnings in the
c_can_platform and peak_canfd driver.

Stephane Grosjean's patch for the peak_canfd driver adds hw timestamps
support in rx skbs.

The next three patches target the xilinx_can driver. One patch by me to
fix checkpatch warnings, one patch by Anssi Hannula to avoid non
requested bus error frames, and a patch by YueHaibing that switches the
driver to devm_platform_ioremap_resource().

Pankaj Sharma contributes two patches for the m_can driver, the first
one adds support for one shot mode, the other support for handling
arbitration errors.

Followed by four patches by YueHaibing, switching the grcan, ifi, rcar,
and sun4i drivers to devm_platform_ioremap_resource()

I'm contributing cleanup patches for the rx-offload helper, while Joakim
Zhang's patch prepares the rx-offload helper for CAN-FD support. The rx
offload users flexcan and ti_hecc are converted accordingly.

The remaining twelve patches target the flexcan driver. First Joakim
Zhang switches the driver to devm_platform_ioremap_resource(). The
remaining eleven patch are by me and clean up the abstract the access of
the iflag1 and iflag2 register both for RX and TX mailboxes. This is a
preparation for the upcoming CAN-FD support.

regards,
Marc
