As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

Remove <common.h> from this driver directory and when needed
add missing include files directly.

This old patch was marked as deferred. Bring it back to life, to continue
towards the removal of common.h
Move this out of the common header and include it only where needed.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

Currently this driver uses a different way to implement the spi xfer,
by modifying some fields of two registers, which is incompatible with the
MTK's original SDK linux driver. This will cause the flash data being
damaged by the SDK driver.
This patch lets the mt7621_spi_set_cs() restore the original register
fields after cs deactivated.

The mt7621 spi controller supports continuous generic half-duplex spi
transaction. There is no need to cache xfer data at all.
To achieve this goal, the OPADDR register must be used as the first data
to be sent. And follows the eight generic DIDO registers. But one thing
different between OPADDR and DIDO registers is OPADDR has a reversed byte
order.
With this patch, any amount of data can be read/written in a single xfer
function call.

This patch lets the spi driver to use clock provided by the clk driver
since the new clk-mt7628 driver provides accurate sys clock frequency.

This patch adds the SPI driver for the MediaTek MT7688 SoC (and
derivates). Its been tested on the LinkIt Smart 7688 and the Gardena
Smart Gateway with and SPI NOR on CS0 and on the Gardena Smart
Gateway additionally with an SPI NAND on CS1.
Note that the SPI controller only supports a max transfer size of 32
bytes. This driver implementes a workaround to enable bigger xfer
sizes to speed up the transfer especially for the SPI NAND support.
