Pull spi updates from Mark Brown:
"There's been quite a lot of generic activity here, but more
administrative than featuers. We also have a bunch of new drivers,
including one that's part of a MFD so we pulled in the core parts of
that:

- Lots of work from both Yang Yingliang and Andy Shevchenko on moving
to host/device/controller based terminology for devices.

- QuadSPI SPI support for Allwinner sun6i.

- New device support Cirrus Logic CS43L43, Longsoon, Qualcomm GENI
QuPv3 and StarFive JH7110 QSPI"

spi: switch to use modern name (part4)

Merge series from Yang Yingliang <yangyingliang@huawei.com>:

I'm trying to rename the legacy name to modern name used in SPI drivers,
this is part4 patchset.

After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy
named function devm_spi_alloc_master/spi_alloc_master() can be replaced.
And also change other legacy name master/slave to modern name host/target
or controller. Each patch compile test passed.

"unsigned int" is more appropriate than "int" for the members
of "struct rzv2m_csi_priv".
Using void* rather than u8* for txbuf and rxbuf allows for
the removal of some type casting.
Remove the unnecessary casting of "data" to "struct rzv2m_csi_priv*"
in function "rzv2m_csi_irq_handler".
Also, members "bytes_per_word" and "errors" introduce gaps
in the structure.
Adjust "struct rzv2m_csi_priv" and its members usage accordingly.

spi: rzv2m-csi: Rework CSI_CKS_MAX definition

Clock "csiclk" gets divided by 2 * CSI_CLKSEL_CKS in order to generate
the serial clock (output from master), with CSI_CLKSEL_CKS ranging from
0x1 (that means "csiclk" is divided by 2) to 0x3FFF ("csiclk" is divided
by 32766). CSI_CKS_MAX is used for referring to the setting
corresponding to the maximum frequency divider.
Value 0x3FFF for CSI_CKS_MAX doesn't really means much to the reader
without an explanation and a more readable definition.

Add a comment with a meaningful description and also replace value
0x3FFF with the corresponding GENMASK, to make it very clear what the
macro means.

spi: rzv2m-csi: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
