a7f7f624 - treewide: replace '---help---' in Kconfig files with 'help'

Sat, 13 Jun 2020 16:50:22 +0000

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, 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 thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/fsi/Kconfig

7ed98ddd - fsi: Add On-Chip Controller (OCC) driver

Thu, 08 Nov 2018 21:05:21 +0000

fsi: Add On-Chip Controller (OCC) driverThe OCC is a device embedded on a POWER processor that collects andaggregates sensor data from the processor and system. The OCC canprovide the raw sensor data as well as perform thermal and powermanagement on the system.This driver provides an atomic communications channel between a serviceprocessor (e.g. a BMC) and the OCC. The driver is dependent on the FSISBEFIFO 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.Signed-off-by: Eddie James Signed-off-by: Andrew Jeffery Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Joel Stanley Signed-off-by: Guenter Roeck List of files: /linux-6.15/drivers/fsi/Kconfig

0ab5fe53 - fsi: Add new central chardev support

Wed, 20 Jun 2018 05:22:52 +0000

fsi: Add new central chardev supportThe various FSI devices (sbefifo, occ, scom, more to come)currently use misc devices.This is problematic as the minor device space for misc islimited and there can be a lot of them. Also it limits ourability to move them to a dedicated /dev/fsi directory orto be smart about device naming and numbering.It also means we have IDAs on every single of these driversThis 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 numberingscheme (as long as chip id <16 and there's only one copyof a given unit type per chip).A single major number and a single IDA are shared for allFSI devices.This doesn't convert the FSI device drivers to use the newscheme yet, they will be converted individually.Signed-off-by: Benjamin Herrenschmidt List of files: /linux-6.15/drivers/fsi/Kconfig

6a794a27 - fsi: master-ast-cf: Add new FSI master using Aspeed ColdFire

Mon, 11 Jun 2018 23:55:04 +0000

fsi: master-ast-cf: Add new FSI master using Aspeed ColdFireThe Aspeed AST2x00 can contain a ColdFire v1 coprocessor whichis currently unused on OpenPower systems.This adds an alternative to the fsi-master-gpio driver thatuses that coprocessor instead of bit banging from the ARMcore itself. The end result is about 4 times faster.The firmware for the coprocessor and its source code can befound at https://github.com/ozbenh/cf-fsi and is system specific.Signed-off-by: Benjamin Herrenschmidt List of files: /linux-6.15/drivers/fsi/Kconfig

9f4a8a2d - fsi/sbefifo: Add driver for the SBE FIFO

Thu, 17 May 2018 05:58:00 +0000

fsi/sbefifo: Add driver for the SBE FIFOThis driver provides an in-kernel and a user API for accessingthe command FIFO of the SBE (Self Boot Engine) of the POWER9processor, via the FSI bus.It provides an in-kernel interface to submit command and receiveresponses, along with a helper to locate and analyse the responsestatus block. It's a simple synchronous submit() type API.The user interface uses the write/read interface that an earlierversion of this driver already provided, however it has somespecific limitations in order to keep the driver simple andavoid using up a lot of kernel memory: - The user should perform a single write() with the command and a single read() to get the response (with a buffer big enough to hold the entire response). - On a write() the command is simply "stored" into a kernel buffer, it is submitted as one operation on the subsequent read(). This allows to have the code write directly from the FIFO into the user buffer and avoid hogging the SBE between the write() and read() syscall as it's critical that the SBE be freed asap to respond to the host. An extra write() will simply replace the previously written command. - A write of a single 4 bytes containing the value 0x52534554 in big endian will trigger a reset request. No read is necessary, the write() call will return when the reset has been acknowledged or times out. - The command is limited to 4K bytes.Signed-off-by: Benjamin Herrenschmidt Tested-by: Joel Stanley --- List of files: /linux-6.15/drivers/fsi/Kconfig

f6a2f8eb - fsi: Match fsi slaves and engines to available dt nodes

Mon, 12 Feb 2018 05:15:45 +0000

fsi: Match fsi slaves and engines to available dt nodesThis change populates device tree nodes for scanned FSI slaves andengines. If the master populates ->of_node of the FSI master device,we'll look for matching slaves, and under those slaves we'll look formatching engines.This means that FSI drivers will have their ->of_node pointer populatedif there's a corresponding DT node, which they can use for furtherdevice discover.Presence of device tree nodes is optional, and only required forfsi device drivers that need extra properties, or subordinate devices,to be enumerated.Signed-off-by: Jeremy Kerr Signed-off-by: Joel Stanley Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/fsi/Kconfig
