Arnd Bergmann 9593bdfa1d Samsung SoC drivers changes for v5.17
1. Exynos ChipID: add Exynos7885 support.
 2. Exynos PMU: add Exynos850 support.
 3. Minor bindings cleanup.
 4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is
    a shared IP block between I2C, UART/serial and SPI. Basically one has
    to choose which feature the USI block will support and later the
    regular I2C/serial/SPI driver will bind and work.
    This merges also one commit with dt-binding headers from my dts64
    pull request.
 
    Together with a future serial driver change, this will break the ABI.
 
    Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards
 
    Why: To properly and efficiently support the USI with new hierarchy
    of USI-{serial,SPI,I2C} devicetree nodes.
 
    Rationale:
    Recently added serial and USI support was short-sighted and did not
    allow to smooth support of other features (SPI and I2C). Adding
    support for USI-SPI and USI-I2C would effect in code duplication.
    Adding support for different USI versions (currently supported is
    USIv2 but support for v1 is planned) would cause even more code
    duplication and create a solution difficult to maintain.
    Since USI-serial and ExynosAutov9 have been added recently, are
    considered fresh development features and there are no supported
    products using them, the code/solution is being refactored in
    non-backwards compatible way.  The compatibility is not broken yet.
    It will be when serial driver changes are accepted.
    The ABI break was discussed with only known users of ExynosAutov9 and
    received their permission.
