Hi, (Mikhail and Jernej: please reply with S-o-b: lines for your patches!)
this series introduces support for the Allwinner A523 SoC family. Compared to v1, a good chunk of those patches have been merged, so we are down from 34 to 20 patches now. There are some small fixes to the pinctrl driver, and the SPL clock bits got updated to fix the conflicts with the now merged A133 support. I rewrote the SPL watchdog code, to avoid the MMIO register C struct. The DRAM driver lost one MMIO register struct. The DT files have now landed in the DT rebasing repo, so we can cherry-pick them from there. Otherwise this now based on latest U-Boot master, which hopefully makes testing easier. If people don't shout, I would like to merge it still during this merge window, since the patches have been around for a while, and people want to use them, alongside the now supported mainline Linux code. So please test and review! ================================== This series introduces support for the Allwinner A523 SoC family. The same die is used in different packages: the A523, A527, T527, and H728: they connect a different set of peripherals to the pins, or enable extra goodies like an NPU. From a U-Boot perspective those chips do not differ much, all the differences are described in the board DT files. To be able to share the SPL clock code, the existing H6 code gets refactored in patches 01-04. This unifies the (CPU) PLL handling across the SoCs supported by this code (H6, H616, A133), and adds support for the separate CPU PLLs on the A523. Patches 05-10 extend the existing Allwinner U-Boot drivers to cope with some of the changed peripherals, this includes the mandatory clock and pinctrl drivers, but also some clock tweaks for the MMC controller driver, and support for the new-ish AXP323 PMIC used on most boards. Patches 11 updates some SPL bits to be able to cope with the A523. Patches 12-15 add the new SPL bits for the A523, most prominently the DRAM initialisation code. Many thanks to Jernej and Mikhail for providing this part, there is a great reverse engineering and testing effort behind this. Patches 16-19 cherry-pick the DT files from the DT rebasing repo. There are more fix patches queued, I will update them once they hit the repo. The final patch adds defconfig files for the three boards that seem to be the most popular at the moment, they include two development boards and one TV box. The most interesting bits in there are the DRAM parameters. Please have a look, review, and test.
