2018-07-27fsi: Add new central chardev supportBenjamin Herrenschmidt3-3/+119
The various FSI devices (sbefifo, occ, scom, more to come) currently use misc devices. This is problematic as the minor device space for misc is limited and there can be a lot of them. Also it limits our ability to move them to a dedicated /dev/fsi directory or to be smart about device naming and numbering. It also means we have IDAs on every single of these drivers This creates a common fsi "device_type" for the optional /dev/fsi grouping and a dev_t allocator for all FSI devices. "Legacy" devices get to use a backward compatible numbering scheme (as long as chip id <16 and there's only one copy of a given unit type per chip). A single major number and a single IDA are shared for all FSI devices. This doesn't convert the FSI device drivers to use the new scheme yet, they will be converted individually.

2018-07-23fsi: master-ast-cf: Add new FSI master using Aspeed ColdFireBenjamin Herrenschmidt5-0/+1755
The Aspeed AST2x00 can contain a ColdFire v1 coprocessor which is currently unused on OpenPower systems. This adds an alternative to the fsi-master-gpio driver that uses that coprocessor instead of bit banging from the ARM core itself. The end result is about 4 times faster. The firmware for the coprocessor and its source code can be found at https://github.com/ozbenh/cf-fsi and is system specific. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2018-07-23dt-bindings: fsi: Document binding for the fsi-master-ast-cf "device"Benjamin Herrenschmidt1-0/+36
This isn't per-se a real device, it's a pseudo-device that represents the use of the Aspeed built-in ColdFire to implement the FSI protocol by bitbanging the GPIOs instead of doing it from the ARM core. Thus it's a drop-in replacement for the existing fsi-master-gpio pseudo-device for use on systems based on the Aspeed chips. It has most of the same properties, plus some more needed to operate the coprocessor. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Reviewed-by: Rob Herring <robh@kernel.org>
2018-07-23devres: Add devm_of_iomap()Benjamin Herrenschmidt2-0/+40
There are still quite a few cases where a device might want to get to a different node of the device-tree, obtain the resources and map them. We have of_iomap() and of_io_request_and_map() but they both have shortcomings, such as not returning the size of the resource found (which can be useful) and not being "managed". This adds a devm_of_iomap() that provides all of these and should probably replace uses of the above in most drivers.

The embedded struct device needs a release function to be able to successfully remove the driver. We remove the devm_gpiod_put() as they are unnecessary (the resources will be released automatically) and because fsi_master_unregister() will cause the master structure to be freed.

2018-07-12fsi: Don't use device_unregister() in fsi_master_register()Benjamin Herrenschmidt1-5/+2
In the error path of fsi_master_register(), we currently use device_unregister(). This will cause the last reference to the structure to be dropped, thus freeing the enclosing structure, which isn't what the callers want. Use device_del() instead so that we return to the caller with a refcount of 1. The caller can then assume that it must use put_device() after a call to fsi_master_register() regardless of whether the latter suceeded or failed.

2018-07-02gpio: aspeed: Add interfaces for co-processor to grab GPIOsBenjamin Herrenschmidt2-20/+246
On the Aspeed chip, the GPIOs can be under control of the ARM chip or of the ColdFire coprocessor. (There's a third command source, the LPC bus, which we don't use or support yet). The control of which master is allowed to modify a given GPIO is per-bank (8 GPIOs). Unfortunately, systems already exist for which we want to use GPIOs of both sources in the same bank. This provides an API exported by the gpio-aspeed driver that an aspeed coprocessor driver can use to "grab" some GPIOs for use by the coprocessor, and allow the coprocessor driver to provide callbacks for arbitrating access. Once at least one GPIO of a given bank has been "grabbed" by the coprocessor, the entire bank is marked as being under coprocessor control. It's command source is switched to the coprocessor. If the ARM then tries to write to a GPIO in such a marked bank, the provided callbacks are used to request access from the coprocessor driver, which is responsible to doing whatever is necessary to "pause" the coprocessor or prevent it from trying to use the GPIOs while the ARM is doing its accesses. During that time, the command source for the bank is temporarily switched back to the ARM.

2018-07-02gpio: aspeed: Add "Read Data" register to read the write latchBenjamin Herrenschmidt1-2/+27
The Aspeed GPIO hardware has a quirk: the value register, for an output GPIO, doesn't contain the last value written (the write latch content) but the sampled input value. This means that when reading back shortly after writing, you can get an incorrect value as the input value is delayed by a few synchronizers. The HW supports a separate read-only register "Data Read Register" which allows you to read the write latch instead. This adds the definition for it, and uses it for the initial population of the GPIO value cache. It will be used more in subsequent patches.
