Peter Griffin <peter.griffin@linaro.org> says: Hi folks, This series provides a few cleanups, bug fixes and feature enhancements for the ufs-exynos driver, particularly for gs101 SoC. Regarding cleanup we remove some unused phy attribute data that isn't required when EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR is not set. Regarding bug fixes the check for EXYNOS_UFS_OPT_UFSPR_SECURE is moved inside exynos_ufs_config_smu() which fixes a Serror in the resume path for gs101. Regarding feature enhancements: * Gear 4 is enabled which has higher speeds and better power management. * WriteBooster capability is enabled for gs101 which increases write performance. * Clock gating and hibern8 capabilities are enabled for gs101. This leads to a significantly cooler phone when running the upstream kernel on Pixel 6. Approximately 10 degrees cooler after 20 minutes at a shell prompt. * AXI bus on gs101 is correctly configured for write line unique transactions * ACG is set to be controlled by UFS_ACG_DISABLE for gs101 Additionally in v3 I've added 2 minor cleanup patches from Tudor and also an update to MAINTAINERS to add myself as a reviewer and the linux-samsung-soc list. Note: In v1 I mentioned the phy hibern8 series in [1] that is still under discussion however further testing reveals hibern8 feature still works without the additional UFS phy register writes done in [1]. So this series can be merged as is and has no runtime dependencies on [1] to be functional.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
