reset: rzg2l-usbphy-ctrl: Assign proper of node to the allocated device

2024-12-06T15:51:28Z

The platform device named "rzg2l-usb-vbus-regulator", allocated by the rzg2l-usbphy-ctrl driver, is used to instantiate a regulator driver. This regulator driver is associated with a device tree (DT) node, which is a child of the rzg2l-usbphy-ctrl DT node. The regulator's DT node allows consumer nodes to reference the regulator and configure the regulator as needed. Starting with commit cd7a38c40b23 ("regulator: core: do not silently ignore provided init_data") the struct regulator_dev::dev::of_node is no longer populated using of_node_get(config->of_node) if the regulator does not provide init_data. Since the rzg2l-usb-vbus-regulator does not provide init_data, this behaviour causes the of_find_regulator_by_node() function to fails, resulting in errors when attempting to request the regulator. To fix this issue, call device_set_of_node_from_dev() for the "rzg2l-usb-vbus-regulator" platform device.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

Get rid of 'remove_new' relic from platform driver struct

2024-12-01T23:12:43Z

The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds

Pull clk updates from Stephen Boyd: "The core framework gained a clk provider helper, a clk consumer helper, and some unit tests for the assigned clk rates feature in DeviceTree. On the vendor driver side, we gained a whole pile of SoC driver support detailed below. The majority in the diffstat is Qualcomm, but there's also quite a few Samsung and Mediatek clk driver additions in here as well. The top vendors is quite common, but the sheer amount of new drivers is uncommon, so I'm anticipating a larger number of fixes for clk drivers this cycle.

Reset controller updates for v6.13 * Split the Amlogic reset-meson driver into platform and auxiliary bus drivers. Add support for the reset controller in the G12 and SM1 audio clock controllers. * Replace the list of boolean parameters to the internal reset_control_get functions with an enum reset_flags bitfield, to make the code more self-descriptive. * Add devres helpers to request pre-deasserted (and automatically re-asserting during cleanup) reset controls. This allows reducing boilerplate in drivers that deassert resets for the lifetime of a device. * Use the new auto-deasserting devres helpers in reset-uniphier-glue as an example. * Add support for the LAN966x PCI device in drivers/misc, as a dependency for the following reset-microchip-sparx5 patches. * Add support for being used on the LAN966x PCI device to the reset-microchip-sparx5 driver. Commit 86f134941a4b ("MAINTAINERS: Add the Microchip LAN966x PCI driver entry") introduces a trivial merge conflict with commit 7280f01e79cc ("net: lan969x: add match data for lan969x") from the net-next tree [1].
