2021-03-04arm64: dts: allwinner: H6: Allow up to 150 MHz MMC bus frequencyAndre Przywara
[ Upstream commit cfe6c487b9a1abc6197714ec5605716a5428cf03 ] The H6 manual explicitly lists a frequency limit of 150 MHz for the bus frequency of the MMC controllers. So far we had no explicit limits in the DT, which limited eMMC to the spec defined frequencies, or whatever the driver defines (both Linux and FreeBSD use 52 MHz here). Put those maximum frequencies in the SoC .dtsi, to allow higher speed modes (which still would need to be explicitly enabled, per board). Tested with an eMMC using HS-200 on a Pine H64. Running at the spec'ed 200 MHz indeed fails with I/O errors, but 150 MHz seems to work stably.

2021-03-04arm64: dts: allwinner: H6: properly connect USB PHY to port 0Andre Przywara
[ Upstream commit da2fb8457f71138d455cba82edec0d34f858e506 ] In recent Allwinner SoCs the first USB host controller (HCI0) shares the first PHY with the MUSB controller. Probably to make this sharing work, we were avoiding to declare this in the DT. This has two shortcomings: - U-Boot (which uses the same .dts) cannot use this port in host mode without a PHY linked, so we were loosing one USB port there. - It requires the MUSB driver to be enabled and loaded, although we don't actually use it. To avoid those issues, let's add this PHY link to the H6 .dtsi file. After all PHY port 0 *is* connected to HCI0, so we should describe it as this. This makes it work in U-Boot, also improves compatiblity when no MUSB driver is loaded (for instance in distribution installers).

2020-04-17arm64: dts: allwinner: h6: Fix PMU compatibleMaxime Ripard
commit 4c7eeb9af3e41ae7d840977119c58f3bbb3f4f59 upstream. The commit 7aa9b9eb7d6a ("arm64: dts: allwinner: H6: Add PMU mode") introduced support for the PMU found on the Allwinner H6. However, the binding only allows for a single compatible, while the patch was adding two. Make sure we follow the binding.

This reverts commits 3d109bdca981 ("ARM: dts: sunxi: Remove useless phy-names from EHCI and OHCI"), 0a3df8bb6dad ("ARM: dts: sunxi: h3/h5: Remove useless phy-names from EHCI and OHCI") and 3c7ab90aaa28 ("arm64: dts: allwinner: Remove useless phy-names from EHCI and OHCI"). It turns out that while the USB bindings were not mentionning it, the PHY client bindings were mandating that phy-names is set when phys is. Let's add it back.
