fsi: Add I2C Responder SCOM driver

2023-08-11T04:02:14+00:00

The I2CR has the capability to directly perform SCOM operations, circumventing the need to drive the FSI2PIB engine. Add a new driver to perform SCOM operations through the I2CR.

fsi: Add IBM I2C Responder virtual FSI master

2023-08-11T04:02:14+00:00

The I2C Responder (I2CR) is an I2C device that translates I2C commands to CFAM or SCOM operations, effectively implementing an FSI master and bus. Signed-off-by: Eddie James Link: https://lore.kernel.org/r/20230612195657.245125-14-eajames@linux.ibm.com Signed-off-by: Joel Stanley

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

fsi: aspeed: add unspecified HAS_IOMEM dependency

2020-02-10T21:45:49+00:00

Currently CONFIG_FSI_MASTER_ASPEED=y implicitly depends on CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get the following build error: ld: drivers/fsi/fsi-master-aspeed.o: in function `fsi_master_aspeed_probe': drivers/fsi/fsi-master-aspeed.c:436: undefined reference to `devm_ioremap_resource' Fix the build error by adding the unspecified dependency.

fsi: Add ast2600 master driver

2019-11-08T10:28:20+00:00

The ast2600 BMC has a pair of FSI masters in it, behind an AHB to OPB bridge. The master driver supports reads and writes of full words, half word and byte accesses to remote CFAMs. It can perform very basic error recovery through resetting of the FSI port when an error is detected, and the issuing of breaks and terms.

fsi: Add On-Chip Controller (OCC) driver

2018-12-03T00:25:28+00:00

The OCC is a device embedded on a POWER processor that collects and aggregates sensor data from the processor and system. The OCC can provide the raw sensor data as well as perform thermal and power management on the system. This driver provides an atomic communications channel between a service processor (e.g. a BMC) and the OCC. The driver is dependent on the FSI SBEFIFO driver to get hardware access through the SBE to the OCC SRAM. Commands are issued to the SBE to send or fetch data to the SRAM.

fsi: Add new central chardev support

2018-07-26T23:57:23+00:00

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.

fsi: master-ast-cf: Add new FSI master using Aspeed ColdFire

2018-07-23T05:22:52+00:00

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
