Hi all, This updated series address the review comments from the original submission in 2021 [1]. It adds a new SPI controller driver for Apple SoCs and is based on spi-sifive. It has been tested with the generic jedec,spi-nor support and with a downstream driver for an Apple specific HID over SPI transport. As usual, I'm splitting off the MAINTAINERS and DT binding changes. We would rather merge the MAINTAINERS change through the Asahi-SoC tree to avoid merge conflicts as things trickle upstream, since we have other submissions touching that section of the file. The DT binding change can go via the SPI tree or via ours, but it's easier if we merge it, as then we can make the DT changes to instantiate it without worrying about DT validation failures depending on merge order. This is mostly Hector's work with a few minor changes to address review comments from me.
