Yes those 2 patches should have my SoB, that was an oversight on my part. Thanks for fixing it :) Peter

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. [1] https://lore.kernel.org/linux-arm-kernel/20241002201555.3332138-3-peter.griffin@linaro.org/T/ regards, Peter Changes since v1: - Remove superfluous struct device parameter to exynos_ufs_shareability() (Peter) - Add patches 8-11 (hibern8 fixes, WLU support etc) Changes since v2: - Add 2 cleanup patches from Tudor to the series and rebase (Tudor) - Fixup various commit messages as per Tudors review feedback (Tudor) - Collect up reviewed-by tags, and CC stable where appropriate (Peter) - Add myself as a reviewer in MAINTAINERS for ufs-exynos driver and add linux-samsung-soc list.
