Subject: [PATCH v1 0/4] arm64: Kconfig: Update ARCH_EXYNOS select configs
Date: Mon, 20 Sep 2021 19:03:45 +0000	[thread overview]
Message-ID: <20210920190350.3860821-1-willmcvicker@google.com> (raw)

This patch series tries to address the issue of ARCH_EXYNOS force selecting
a handful of drivers without allowing the vendor to override any of the
default configs. This takes away from the flexibilty of compiling a generic
kernel with exynos kernel modules. For example, it doesn't allow vendors to
modularize these drivers out of the core kernel in order to share a generic
kernel image across multiple devices that require device-specific kernel
modules.

To address this without impacting the existing behavior, this series
switches the default config logic for the offending configs to use "default
y if ARCH_EXYNOS" versus having ARCH_EXYNOS directly select them. I have
verified that these patches do not impact the default aarch64 .config.

Will McVicker (4):
  clk: samsung: change COMMON_CLK_SAMSUNG default config logic
  soc: samsung: change SOC_SAMSUNG default config logic
  pinctrl: samsung: change PINCTRL_EXYNOS default config logic
  rtc: change HAVE_S3C_RTC default config logic
