2023-10-27Revert "nvmem: add new config option"Rafał Miłecki
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.

2023-10-27PCI: qcom-ep: Add dedicated callback for writing to DBI2 registersManivannan Sadhasivam
The DWC core driver exposes the write_dbi2() callback for writing to the DBI2 registers in a vendor-specific way. On the Qcom EP platforms, the DBI_CS2 bit in the ELBI region needs to be asserted before writing to any DBI2 registers and deasserted once done. So, let's implement the callback for the Qcom PCIe EP driver so that the DBI2 writes are correctly handled in the hardware. Without this callback, the DBI2 register writes like BAR size won't go through and as a result, the default BAR size is set for all BARs.

2023-10-27staging: fbtft: Convert to platform remove callback returning voidUwe Kleine-König
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 (mostly) ignored 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. The function fbtft_driver_remove_pdev() (that exists several times as it's part of a macro expansion) returns zero unconditionally, so it can be trivially converted to return void without semantic changes.

2023-10-27staging: olpc_dcon: Remove I2C_CLASS_DDC supportHeiner Kallweit
olpc_dcon is the only remaining i2c client device driver declaring I2C_CLASS_DDC support after the legacy eeprom driver has been removed. olpc_dcon is only used on olpc devices, connected to an i2c adapter driven by scx200_acb. This adapter driver declares support for I2C_CLASS_HWMON and I2C_CLASS_SPD. Therefore we can safely drop I2C_CLASS_DDC support in olpc_dcon. That's the last step before I2C_CLASS_DDC can be removed in general. This patch is solely based on documentation, and I don't have an olpc device for testing. Therefore some testing would be appreciated before patch is applied.

2023-10-27usb: raw-gadget: properly handle interrupted requestsAndrey Konovalov
Currently, if a USB request that was queued by Raw Gadget is interrupted (via a signal), wait_for_completion_interruptible returns -ERESTARTSYS. Raw Gadget then attempts to propagate this value to userspace as a return value from its ioctls. However, when -ERESTARTSYS is returned by a syscall handler, the kernel internally restarts the syscall. This doesn't allow userspace applications to interrupt requests queued by Raw Gadget (which is required when the emulated device is asked to switch altsettings). It also violates the implied interface of Raw Gadget that a single ioctl must only queue a single USB request. Instead, make Raw Gadget do what GadgetFS does: check whether the request was interrupted (dequeued with status == -ECONNRESET) and report -EINTR to userspace.

2023-10-27usb: gadget: aspeed_udc: Convert to platform remove callback returning voidUwe Kleine-König
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(). ast_udc_remove() is one of these functions that return an error code after doing only a partial cleanup. Replace the core's error message by a more drastic one and still convert the driver to .remove_new(). Note the only semantic change here is the changed error message.

2023-10-27dt-bindings: usb: fsa4480: Add compatible for OCP96011Luca Weiss
The Orient-Chip OCP96011 is generally compatible with the FSA4480, add a compatible for it with the fallback on fsa4480. However the AUX/SBU connections are expected to be swapped compared to FSA4480, so document this in the data-lanes description.

2023-10-27usb: typec: fsa4480: Add support to swap SBU orientationLuca Weiss
On some hardware designs the AUX+/- lanes are connected reversed to SBU1/2 compared to the expected design by FSA4480. Made more complicated, the otherwise compatible Orient-Chip OCP96011 expects the lanes to be connected reversed compared to FSA4480. * FSA4480 block diagram shows AUX+ connected to SBU2 and AUX- to SBU1. * OCP96011 block diagram shows AUX+ connected to SBU1 and AUX- to SBU2. So if OCP96011 is used as drop-in for FSA4480 then the orientation handling in the driver needs to be reversed to match the expectation of the OCP96011 hardware. Support parsing the data-lanes parameter in the endpoint node to swap this in the driver. The parse_data_lanes_mapping function is mostly taken from nb7vpq904m.c.

2023-10-27dt-bindings: usb: fsa4480: Add data-lanes property to endpointLuca Weiss
Allow specifying data-lanes to reverse the muxing orientation between AUX+/- and SBU1/2 where necessary by the hardware design. In the mux there's a switch that needs to be controlled from the OS, and it either connects AUX+ -> SBU1 and AUX- -> SBU2, or the reverse: AUX+ -> SBU2 and AUX- -> SBU1, depending on the orientation of how the USB-C connector is plugged in. With this data-lanes property we can now specify that AUX+ and AUX- connections are swapped between the SoC and the mux, therefore the OS needs to consider this and reverse the direction of this switch in the mux. _______ _______ | | | |-- HP --| | |-- MIC --| |or SoC | | MUX |-- SBU1 ---> To the USB-C Codec |-- AUX+ --| |-- SBU2 ---> connected |-- AUX- --| | ______| |_____| (thanks to Neil Armstrong for this ASCII art) Signed-off-by: Luca Weiss <luca.weiss@fairphone.com> Reviewed-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20231020-fsa4480-swap-v2-1-9a7f9bb59873@fairphone.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
