2022-12-02tty: serial: kgdboc: synchronize tty_find_polling_driver() and ↵John Ogness
register_console() Calling tty_find_polling_driver() can lead to uart_set_options() being called (via the poll_init() callback of tty_operations) to configure the uart. But uart_set_options() can also be called by register_console() (via the setup() callback of console). Take the console_list_lock to synchronize against register_console() and also use it for console list traversal. This also ensures the console list cannot change until the polling console has been chosen.

2022-12-02tty: serial: kgdboc: use console_list_lock for list traversalJohn Ogness
configure_kgdboc() uses the console_lock for console list iteration. Use the console_list_lock instead because list synchronization responsibility will be removed from the console_lock in a later change. The SRCU iterator could have been used here, but a later change will relocate the locking of the console_list_lock to also provide synchronization against register_console(). Note, the console_lock is still needed to serialize the device() callback with other console operations.

2022-12-02printk, xen: fbfront: create/use safe function for forcing preferredJohn Ogness
With commit 9e124fe16ff2("xen: Enable console tty by default in domU if it's not a dummy") a hack was implemented to make sure that the tty console remains the console behind the /dev/console device. The main problem with the hack is that, after getting the console pointer to the tty console, it is assumed the pointer is still valid after releasing the console_sem. This assumption is incorrect and unsafe. Make the hack safe by introducing a new function console_force_preferred_locked() and perform the full operation under the console_list_lock.

2022-12-01cxl/acpi: Simplify cxl_nvdimm_bridge probingDan Williams
The 'struct cxl_nvdimm_bridge' object advertises platform CXL PMEM resources. It coordinates with libnvdimm to attach nvdimm devices and regions for each corresponding CXL object. That coordination is complicated, i.e. difficult to reason about, and it turns out redundant. It is already the case that the CXL core knows how to tear down a cxl_region when a cxl_memdev goes through ->remove(), so that pathway can be extended to directly cleanup cxl_nvdimm and cxl_pmem_region objects. Towards the goal of ripping out the cxl_nvdimm_bridge state machine, arrange for cxl_acpi to optionally pre-load the cxl_pmem driver so that the nvdimm bridge is active synchronously with devm_cxl_add_nvdimm_bridge(), and remove all the bind attributes for the cxl_nvdimm* objects since the cxl root device and cxl_memdev bind attributes are sufficient.

2022-12-01clk: qcom: ipq8074: populate fw_name for all parentsRobert Marko
It appears that having only .name populated in parent_data for clocks which are only globally searchable currently will not work as the clk core won't copy that name if there is no .fw_name present as well. So, populate .fw_name for all parent clocks in parent_data.

2022-12-01clk: qcom: krait-cc: convert to parent_data APIChristian Marangi
Modernize the krait-cc driver to parent-data API and refactor to drop any use of parent_names. From Documentation all the required clocks should be declared in DTS so fw_name can be correctly used to get the parents for all the muxes. .name is also declared to save compatibility with old DT. While at it also drop some hardcoded index and introduce an enum to make index values more clear.

2022-12-01clk: qcom: krait-cc: handle secondary mux sourcing out of acpu_auxChristian Marangi
Some bootloader may leave the system in an even more undefined state with the secondary mux of L2 or other cores sourcing out of the acpu_aux parent. This results in the clk set to the PXO rate or a PLL8 rate. The current logic to reset the mux and set them to a defined state only handle if the mux are configured to source out of QSB. Change this and force a new and defined state if the current clk is lower than the aux rate. This way we can handle any wrong configuration where the mux is sourcing out of QSB (rate 225MHz, currently set to a virtual rate of 1), PXO rate (rate 25MHz) or PLL8 (needs to be configured to run at 384Mhz).

clk-krait ignore any rate change if clk is not flagged as enabled. Correctly enable the secondary mux and div clk to correctly change rate instead of silently ignoring the request.

2022-12-01clk: qcom: krait-cc: fix wrong parent order for secondary muxChristian Marangi
The secondary mux parent order is swapped. This currently doesn't cause problems as the secondary mux is used for idle clk and as a safe clk source while reprogramming the hfpll. Each mux have 2 or more output but he always have a safe source to switch while reprogramming the connected pll. We use a clk notifier to switch to the correct parent before clk core can apply the correct rate. The parent to switch is hardcoded in the mux struct. For the secondary mux the safe source to use is the qsb parent as it's the only fixed clk as the acpus_aux is a pll that can source from pxo or from pll8. The hardcoded safe parent for the secondary mux is set to index 0 that in the secondary mux map is set to 2. But the index 0 is actually acpu_aux in the parent list. Fix the swapped parents to correctly handle idle frequency and output a sane clk_summary report.
