can: mcp251xfd: move mcp251xfd_timestamp_start()/stop() into mcp251xfd_chip_start/stop()

commit a7801540f325d104de5065850a003f1d9bdc6ad3 upstream.

The mcp251xfd wakes up from Low Power or Sleep Mode when SPI activity
is detected. To avoid this, make sure that the timestamp worker is
stopped before shutting down the chip.

Split the starting of the timestamp worker out of
mcp251xfd_timestamp_init() into the separate function
mcp251xfd_timestamp_start().

Call mcp251xfd_timestamp_init() before mcp251xfd_chip_start(), move
mcp251xfd_timestamp_start() to mcp251xfd_chip_start(). In this way,
mcp251xfd_timestamp_stop() can be called unconditionally by
mcp251xfd_chip_stop().

can: mcp251xfd: clarify the meaning of timestamp

[ Upstream commit e793c724b48ca8cae9693bc3be528e85284c126a ]

The mcp251xfd chip is configured to provide a timestamp with each
received and transmitted CAN frame. The timestamp is derived from the
internal free-running timer, which can also be read from the TBC
register via SPI. The timer is 32 bits wide and is clocked by the
external oscillator (typically 20 or 40 MHz).

To avoid confusion, we call this timestamp "timestamp_raw" or "ts_raw"
for short.

Using the timecounter framework, the "ts_raw" is converted to 64 bit
nanoseconds since the epoch. This is what we call "timestamp".

This is a preparation for the next patches which use the "timestamp"
to work around a bug where so far only the "ts_raw" is used.

The first patch is by me, for the mailmap file and maps the email
address of two former ESD employees to a newly created role account.

The next 3 patches are by Oleksij Rempel and add support for GPIO
based switchable CAN bus termination.

The next 3 patches are by Vincent Mailhol. The first one changes the
CAN netlink interface to not bail out if the user switched off
unsupported features. The next one adds Vincent as the maintainer of
the etas_es58x driver and the last one cleans up the documentation of
struct es58x_fd_tx_conf_msg.

The next patch is by me, for the mcp251xfd driver and marks some
instances of struct mcp251xfd_priv as const. Lad Prabhakar contributes
2 patches for the rcar_canfd driver, that add support for RZ/G2L
family.

The next 5 patches target the m_can/tcan45x5 driver. 2 are by me an
fix trivial checkpatch warnings. The remaining 3 patches are by Matt
Kline and improve the performance on the SPI based tcan4x5x chip by
batching FIFO reads and writes.

The last 7 patches are for the c_can driver. Dario Binacchi's patch
converts the DT bindings to yaml, 2 patches by me fix a typo and
rename a macro to properly represent the usage. The last 4 patches are
again by Dario Binacchi and provide a performance improvement for the
TX path by operating the TX mailboxes as a true FIFO.
