MFC r331868, r332046, r332194-r332196, r332198, r332219, r332231, r332233, r332240, r332258-r332259, r332261, r332292
r331868:
Add opt_platform.h for several modules that have #ifdef FDT in the source.
Submitted by: Andre Albsmeier <Andre.Albsmeier@siemens.com>
r332046:
Add a missing MODULE_DEPEND().
r332194:
Add support for writing/changing spi device ivars. The SPI mode (polarity
and phase) and the maximum bus speed can be changed. The chip select
number cannot be changed, because the device instances which are children
of spibus are inherently associated with the chip select number they were
instantiated for.
r332195:
A couple minor improvements to spibus.c...
- Change the description string to "SPI bus" (was "spibus bus").
- This is the default driver for a SPI bus, not a generic implementation,
so return the probe value that indicates such.
- Use device_delete_children() at detach time, instead of a local loop
to enumerate the children and detach each one individually.
r332196:
Return BUS_PROBE_DEFAULT, not zero, because this is not the one driver
implementation that must be used, it's just the base system default driver.
Also add a comment noting that we're being more liberal about the bus
frequency property than the dts binding documents require.
r332198:
Arrange the list of generated sources as 1-per-line alphbetical, and add
the files required when building for FDT-based systems.
r332219:
Remove the existing identify() hack to force-add a spigen device on
FDT-based systems, and instead add proper FDT probe code. Because this
driver is freebsd-specific and just provides generic userland access to run
spibus transactions, there is no bindings document to mandate a compatible
string, so just arbitrarily use "freebsd,spigen".
r332231:
Generate a spibus_set_[ivarname]() convenience function for each ivar,
now that they can be set.
r332233:
Add an ioctl to get/set the SPI transfer mode. Also, make the bus clock
frequency ioctl actually set the corresponding ivar instead of just storing
the value locally in the softc (and then not using it for anything). Also,
return the correct error code if the ioctl cmd is not recognized.
r332240:
Add the ioctl definitions for spigen get/set spi mode. Should have been
part of r332233.
r332258:
Don't check for impossible NULL return from malloc(..., M_WAITOK).
r332259:
Cast the data pointer to the correct type for the data being accessed (as
opposed to one that accidentally worked on the one arch I test-compiled for
on my first try).
Reported by: np@, O. Hartmann <ohartmann@walstatt.org>
Pointy hat: ian@
r332261:
Add a manpage for spigen(4).
r332292:
Allow hinted attachment on FDT-based systems. Instead of returning ENXIO
when the FDT data doesn't enable the device instance, return
BUS_PROBE_NOWILDCARD, the same as for non-FDT systems.

Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.
Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

[spi] reformat message
This commit corrects print of nomatch (newline was too early)
Submitted by: Hiroki Mori <yamori813@yahoo.co.jp>
Reviewed by: ray, loos, mizhka
Differential Revision: https://reviews.freebsd.org/D8749
r310229:
ofw_spi: Parse property for the SPI mode and CS polarity.
As cs is stored in a uint32_t, use the last bit to store the
active high flag as it's unlikely that we will have that much CS.

[spibus] small code refactoring
Merge 3 sequential printf calls into one.
Reported by: rpokala
Reviewed by: rpokala, adrian
Approved by: adrian (mentor)
Differential Revision: https://reviews.freebsd.org/D8795
r327260:
SPDX: fix wrong license ID tag in dev/spibus.
r329539:
Provide public declarations for ofw_spibus_driver and ofw_spibus_devclass
so other drivers can refer to them in DRIVER_MODULE() decls.
r329544:
Add modules/spi as a gathering point for SPI-related modules, analagous to
modules/i2c for i2c/iicbus modules. Build spibus as a module.
r329545:
Add ofw_bus_if.h to SRCS.
r329546:
Build at45d and mx25l SPI flash drivers as modules.
r329620:
Add missing MODULE_DEPENDS().
r329729:
Remove some files that snuck in via cut and paste.
Having these compiled into the module causes the kobj method descriptors
to be resolved incorrectly (by the compile-time linker instead of the
kernel linker), which then leads to hours of frustrating debugging.
r329911:
Add a functional detach() routine, to make things kldunload-friendly.
r329999:
Add a SPI driver for imx5 and imx6.
It can be compiled into the kernel with "device imx_spi" or loaded as a
module, which is also named "imx_spi".
