2023-10-27cdx: add sysfs for subsystem, class and revisionAbhijit Gangurde8-3/+135
CDX controller provides subsystem vendor, subsystem device, class and revision info of the device along with vendor and device ID in native endian format. CDX Bus system uses this information to bind the cdx device to the cdx device driver.

2023-10-27greybus: Add BeaglePlay Linux DriverAyush Singh4-0/+514
Add the Greybus host driver for BeaglePlay board by BeagleBoard.org. The current greybus setup involves running SVC in a user-space application (GBridge) and using netlink to communicate with kernel space. GBridge itself uses wpanusb kernel driver, so the greybus messages travel from kernel space (gb_netlink) to user-space (GBridge) and then back to kernel space (wpanusb) before reaching CC1352. This driver directly communicates with CC1352 (running SVC Zephyr application). Thus, it simplifies the complete greybus setup eliminating user-space GBridge. This driver is responsible for the following: - Start SVC (CC1352) on driver load. - Send/Receive Greybus messages to/from CC1352 using HDLC over UART. - Print Logs from CC1352. - Stop SVC (CC1352) on driver load.

2023-10-27Revert "nvmem: add new config option"Rafał Miłecki3-4/+1
This reverts commit 517f14d9cf3533d5ab4fded195ab6f80a92e378f. Config option "no_of_node" is no longer needed since adding a more explicit and targeted option "add_legacy_fixed_of_cells". That "no_of_node" config option was needed *earlier* to help mtd's case. DT nodes of MTD partitions (that are also NVMEM devices) may contain subnodes. Those SHOULD NOT be treated as NVMEM fixed cells. To prevent NVMEM core code from parsing subnodes a "no_of_node" option was added (and set to true in mtd) to make for_each_child_of_node() in NVMEM a no-op. That was a bit hacky because it was messing with "of_node" pointer to achieve some side-effect. With the introduction of "add_legacy_fixed_of_cells" config option things got more explicit. MTD subsystem simply tells NVMEM when to look for fixed cells and there is no need to hack "of_node" pointer anymore.

The smatch warns about uncleaned resources in case the parport_register_port() fails: parport_register_port() warn: '&tmp->full_list' not removed from list This is indeed an issue introduced when converting code to use kasprintf(). However, the whole kasprintf() dance in this case is not needed as dev_set_name() can handle the formatted input and produces the same result. So, the solution is to delegate name forming to the dev_set_name() and make device_register() error path to deal with error handling (via put_device() call).

Binding for fixed NVMEM cells defined directly as NVMEM device subnodes has been deprecated. It has been replaced by the "fixed-layout" NVMEM layout binding. New syntax is meant to be clearer and should help avoiding imprecise bindings. NVMEM subsystem already supports the new binding. It should be a good idea to limit support for old syntax to existing drivers that actually support & use it (we can't break backward compatibility!). That way we additionally encourage new bindings & drivers to ignore deprecated binding. It wasn't clear (to me) if rtc and w1 code actually uses old syntax fixed cells.

Only took 13 years :) One small patch added then reverted due to a report of test breakage (ashai-kasei,ak8975: Drop deprecated enums.) An immutable branch was used for some hid-senors changes in case there was a need to take them into the HID tree as well. New device support ----------------- adi,hmc425a - Add support for HMC540SLP3E broadband 4-bit digital attenuator. kionix,kx022a - Add support for the kx132-1211 accelerometer. Require significant driver rework to enable this including add a chip type specific structure to deal with the chip differences. - Add support for the kx132acr-lbz accelerometer (subset of the kx022a feature set). lltc,ltc2309 - New driver for this 8 channel ADC. microchip,mcp3911 - Add support for rest of mcp391x family of ADCs (there are various differences beyond simple channel count variation. Series includes some general driver cleanup. microchip,mcp3564 - New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564 and their R variants of 16/24bit ADCs. A few minor fixed followed. rohm,bu1390 - New driver for this pressure sensor. Staging graduation ------------------ adi,ad1210 (after 13 or so years :) - More or less a complete (step-wise) rewrite of this resolver driver to bring it up to date with modern IIO standards. The fault signal handling mapping to event channels was particularly complex and significant part of the changes. Features -------- iio-core - Add chromacity and color temperature channel types. adi,ad7192 - Oversampling ratio control (called fast settling in datasheet). adi,adis16475 - Add core support and then driver support for delta angle and delta velocity channels. These are intended for summation to establish angle and velocity changes over larger timescales. Fix was needed for alignment after the temperature channel. Further fix reduced set of devices for which the buffer support was applicable as seems burst reads don't cover these on all devices. hid-sensors-als - Chromacity and color temperatures support including in amd sfh. stx104 - Add support for counter subsystem to this multipurpose device. ti,twl6030 - Add missing device tree binding description. Clean up and minor fixes. ------------------------ treewide - Drop some unused declarations across IIO. - Make more use of device_get_match_data() instead of OF specific approaches. Similar cleanup to sets of drivers. - Stop platform remove callbacks returning anything by using the temporary remove_new() callback. - Use i2c_get_match_data() to cope nicely with all types of ID table entry. - Use device_get_match_data() for various platform device to cope with more types of firmware. - Convert from enum to pointer in ID tables allowing use of i2c_get_match_data(). - Fix sorting on some ID tables. - Include specific string helper headers rather than simply string_helpers.h docs - Better description of the ordering requirements etc for available_scan_masks. tools - Handle alignment of mixed sizes where the last element isn't the biggest correctly. Seems that doesn't happen often! adi,ad2s1210 - Lots of work from David Lechner on this driver including a few fixes that are going with the rework to avoid slowing that down. adi,ad4310 - Replace deprecated devm_clk_register() adi,ad74413r - Bring the channel function setting inline with the datasheet. adi,ad7192 - Change to FIELD_PREP(), FIELD_GET(). - Calculate f_order from the sinc filter and chop filter states. - Move more per chip config into data in struct ad7192_chip_info - Cleanup unused parameter in channel macros. adi,adf4350 - Make use of devm_* to simplify error handling for many of the setup calls in probe() / tear down in remove() and error paths. Some more work to be done on this one. - Use dev_err_probe() for errors in probe() callback. adi,adf4413 - Typo in function name prefix. adi,adxl345 - Add channel scale to the chip type specific structure and drop using a type field previously used for indirection. asahi,ak8985 - Fix a mismatch introduced when switching from enum->pointers in the match tables. amlogic,meson - Expand error logging during probe. invensense,mpu6050 - Support level-shifter control. Whilst no one is sure exactly what this is doing it is needed for some old boards. - Document mount-matrix dt-binding. mediatek,mt6577 - Use devm_clk_get_enabled() to replace open coded version and move everything over to being device managed.

2023-10-18interconnect: qcom: Convert to platform remove callback returning voidUwe Kleine-König19-21/+19
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Several drivers use qcom_icc_rpmh_remove() as remove callback which returns zero unconditionally. Make it return void and use .remove_new in the drivers. There is no change in behaviour.

Note, we may not use list_for_each_entry() as at the end of the list the iterator will point to an invalid entry and may not be dereferenced.

GSC devices perform legal firmware initiated resets due to state transition that may appear as unexpected to the driver. Lower the log level for those devices to debug level and save the firmware status registers. When the device comes out of the reset it is possible to check whether the resets was due to a firmware error or an exception and only than produce a warning.
