The "check" variable isn't necessarily initialized when we print it out in the debugging messages. It's a pretty haphazard affair and it doesn't matter very much what we initialize "check" to. Signed-off-by:

The A83T has 3 USB PHYs, 1 for OTG, 1 for standard USB, 1 for USB HSIC. The phy initialization procedure is very different from other SoCs, but the PMU bits are the same, with additional bits for HSIC. Signed-off-by:

On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires two clocks instead of one. On all Allwinner SoCs that share the common USB PHY design supported by the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there is at most one HSIC PHY, typically the last. In this patch we take advantage of these known constraints and store an index in the compatible-string-related config structure describing which PHY is HSIC, needing the extra hsic_12M clock.

The driver is actually for T-PHY which supports USB3.0, PCIe and SATA, and supports more SoCs now, but not just only for series of mt65xx SoCs, so the name of file, data struct, functions etc with 'mt65xx' may cause misunderstanding when new SoCs are supported. Here rename them to reflect the real functions and also enhance readability. And also update MAINTAINERS file to reflect the correct driver Signed-off-by:

Presently, the phy pipe clock's name is assumed to be either usb3_phy_pipe_clk_src or pcie_XX_pipe_clk_src (where XX is the phy lane's number). However, this will not work if an SoC has more than one instance of the phy. Hence, instead of assuming the name of the clock, fetch it from the DT. Reviewed-by:

Pull documentation format standardization from Jonathan Corbet: "This series converts a number of top-level documents to the RST format without incorporating them into the Sphinx tree. The hope is to bring some uniformity to kernel documentation and, perhaps more importantly, have our existing docs serve as an example of the desired formatting for those that will be added later. Mauro has gone through and fixed up a lot of top-level documentation files to make them conform to the RST format, but without moving or renaming them in any way. This will help when we incorporate the ones we want to keep into the Sphinx doctree, but the real purpose is to bring a bit of uniformity to our documentation and let the top-level docs serve as examples for those writing new ones" * tag 'standardize-docs' of git://git.lwn.net/linux: (84 commits) docs: kprobes.txt: Fix whitespacing tee.txt: standardize document format cgroup-v2.txt: standardize document format dell_rbu.txt: standardize document format zorro.txt: standardize document format xz.txt: standardize document format xillybus.txt: standardize document format vfio.txt: standardize document format vfio-mediated-device.txt: standardize document format unaligned-memory-access.txt: standardize document format this_cpu_ops.txt: standardize document format svga.txt: standardize document format static-keys.txt: standardize document format smsc_ece1099.txt: standardize document format SM501.txt: standardize document format siphash.txt: standardize document format sgi-ioc4.txt: standardize document format SAK.txt: standardize document format rpmsg.txt: standardize document format robust-futexes.txt: standardize document format ...

Also print a warning if get_random_*() is called before the CRNG is initialized. By default, only one single-line warning will be printed per boot.

Unfortunately, on some models of some architectures getting a fully seeded CRNG is extremely difficult, and so this can result in dmesg getting spammed for a surprisingly long time. This is really bad from a security perspective, and so architecture maintainers really need to do what they can to get the CRNG seeded sooner after the system is booted. However, users can't do anything actionble to address this, and spamming the kernel messages log will only just annoy people. For developers who want to work on improving this situation, CONFIG_WARN_UNSEEDED_RANDOM has been renamed to CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always print the first use of unseeded randomness. This way, hopefully the security obsessed will be happy that there is _some_ indication when the kernel boots there may be a potential issue with that architecture or subarchitecture. To see all uses of unseeded randomness, developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM. Signed-off-by:
