2022-04-24clk: sunxi-ng: sun6i-rtc: Mark rtc-32k as criticalSamuel Holland
Because some newer hardware variants have multiple possible parents for the RTC's timekeeping clock, this driver models it as a "rtc-32k" clock. However, it does not add any consumer for this clock. This causes the common clock framework to disable it, preventing RTC time access. Since the RTC's timekeeping clock should always be enabled, regardless of which drivers are loaded, let's mark this clock as critical instead of adding a consumer in the RTC driver.

2022-04-24kvmalloc: use vmalloc_huge for vmalloc allocationsLinus Torvalds
Since commit 559089e0a93d ("vmalloc: replace VM_NO_HUGE_VMAP with VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc is an opt-in strategy, because it caused a number of problems that weren't noticed until x86 enabled it too. One of the issues was fixed by Nick Piggin in commit 3b8000ae185c ("mm/vmalloc: huge vmalloc backing pages should be split rather than compound"), but I'm still worried about page protection issues, and VM_FLUSH_RESET_PERMS in particular. However, like the hash table allocation case (commit f2edd118d02d: "page_alloc: use vmalloc_huge for large system hash"), the use of kvmalloc() should be safe from any such games, since the returned pointer might be a SLUB allocation, and as such no user should reasonably be using it in any odd ways. We also know that the allocations are fairly large, since it falls back to the vmalloc case only when a kmalloc() fails. So using a hugepage mapping seems both safe and relevant. This patch does show a weakness in the opt-in strategy: since the opt-in flag is in the 'vm_flags', not the usual gfp_t allocation flags, very few of the usual interfaces actually expose it. That's not much of an issue in this case that already used one of the fairly specialized low-level vmalloc interfaces for the allocation, but for a lot of other vmalloc() users that might want to opt in, it's going to be very inconvenient. We'll either have to fix any compatibility problems, or expose it in the gfp flags (__GFP_COMP would have made a lot of sense) to allow normal vmalloc() users to use hugepage mappings. That said, the cases that really matter were probably already taken care of by the hash tabel allocation.

Three chip_ops are implemented in this patch. The ::set_txpwr_ctrl and ::init_txpwr_unit are called when we up interface and then configure TX power registers to initial values. The ::set_txpwr_ctrl is to configure 'txpwr_ref' to make basic output TX power of OFDM and CCK rate to be the same. The ::init_txpwr_unit is to initialize TSSI (a method to do TX power compensation depends on thermal value) control and bandedge. The ::set_txpwr is called once switching channel. First, it sets TX power for each rate section (e.g. CCK, OFDM), and then sets TX power offset between 1SS and 2SS rate. Finally, it sets TX power limit to prevent power over regulation.

In low power mode, we need to pause PCI to configure IMR and PCI ring index registers accordingly, because the regular registers are power-off in this mode. In the transition moment named paused in code, we can't touch ring index, so don't kick off DMA immediately. Instead, queue them into pending queue, and kick off after the moment.

2022-04-23rtw89: 8852c: add set channel of BB partPing-Ke Shih
BB does many settings during setting channel. First is to configure CCK for 2G channels, and then basic channel and bandwidth settings with a encoded channel index that will report to driver when we receive packets. Configure spur elimination to avoid spur of CSI and NBI tones in certain frequencies. Also, it initializes BT grant to arrange path sharing with BT according to band. Finally, reset TSSI and BB hardware to ensure it stays in initial state.
