fsi: core: Fix small accesses and unaligned offsets via sysfs

2019-12-31T15:45:09Z

[ Upstream commit 9f4c2b516b4f031e3cd0e45957f4150b3c1a083d ] Subtracting the offset delta from four-byte alignment lead to wrapping of the requested length where `count` is less than `off`. Generalise the length handling to enable and optimise aligned access sizes for all offset and size combinations. The new formula produces the following results for given offset and count values: offset count | length --------------+------- 0 1 | 1 0 2 | 2 0 3 | 2 0 4 | 4 0 5 | 4 1 1 | 1 1 2 | 1 1 3 | 1 1 4 | 1 1 5 | 1 2 1 | 1 2 2 | 2 2 3 | 2 2 4 | 2 2 5 | 2 3 1 | 1 3 2 | 1 3 3 | 1 3 4 | 1 3 5 | 1 We might need something like this for the cfam chardevs as well, for example we don't currently implement any alignment restrictions / handling in the hardware master driver.

fsi: scom: Don't abort operations for minor errors

2019-08-28T20:59:18Z

The scom driver currently fails out of operations if certain system errors are flagged in the status register; system checkstop, special attention, or recoverable error. These errors won't impact the ability of the scom engine to perform operations, so the driver should continue under these conditions. Also, don't do a PIB reset for these conditions, since it won't help.

fsi: sbefifo: Don't fail operations when in SBE IPL state

SBE fifo operations should be allowed while the SBE is in any of the "IPL" states. Operations should succeed in this state.

fsi/core: Fix error paths on CFAM init

2019-07-03T01:12:53Z

Change d1dcd67825 re-worked the struct fsi_slave initialisation in fsi_slave_init, but introduced a few inconsitencies: the slave->dev is now registered through cdev_device_add, but we may kfree() the device out from underneath the cdev registration. We may also leave an IDA allocated. This change fixes the error paths, so that we kfree() only before the device is registered with the core code. We also move the smode write to before we start creating proper devices, as it's the most likely to fail. We also remove the IDA-allocated minor on error, and properly clean up the of_node.
