Hi Arnd, Olof,

Four pull requests and two separate, trailing patches (arm64 and defconfig).

Please see the "[GIT PULL 1/6] samsung: soc: drivers: for v5.17" for future ABI
break explanation.

Best regards,
Krzysztof

Hi,

See below in the tag explanation for ABI impact by this change and future
serial driver changes. ABI break is not yet broken, although changes are not
bisectable between DTS and driver.

Best regards,
Krzysztof

  dt-bindings: soc: samsung: keep SoC driver bindings together (2021-12-18 11:55:59 +0100)

----------------------------------------------------------------
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.

1. Minor fixes for S3C platforms.
2. Remove HAVE_S3C2410_I2C Kconfig symbol - not really useful.

Thanks a lot for the detailed description, very helpful!

I've applied pull requests 1 through 4, though it seems that once more
the automated emails did not go out.

I can't find the two defconfig patches you mentioned in the introductory
mail, neither in patchwork nor in my inbox, I assume these were
numbered 5/6 and 6/6?

Yes, these were patches 5/6 and 6/6 but maybe I made mistakes in address
list. Let me resend them now.

Hi Arnd and Olof,

I forgot to mention possible conflict here with arm tree. Conflict is
easy to resolve - just remove lines in all cases like:

--- a/arch/arm/Kconfig
+++ b/arch/arm/Kconfig
@@@ -471,7 -478,7 +471,6 @@@ config ARCH_S3C24X
  	select CLKSRC_SAMSUNG_PWM
  	select GPIO_SAMSUNG
  	select GPIOLIB
- 	select HAVE_S3C2410_I2C if I2C
 -	select GENERIC_IRQ_MULTI_HANDLER
  	select NEED_MACH_IO_H
  	select S3C2410_WATCHDOG
  	select SAMSUNG_ATAGS


Best regards,
Krzysztof
