Here is the 4th revision of the series; the review mail got lost in my inbox so this is a bit late, sorry for the delay! The previous revision is tested on Loongson-2K by Jiaxun Yang, and this revision contains no functional changes so should work on 2K too. I compiled and tested this revision on a Loongson-3A4000 & LS7A system. This patch series adds support for the RTC module found on various Loongson systems with the Loongson-2K SoC or the LS7A bridge chip. The driver is rewritten from an out-of-tree version to meet mainline standards. I write kernel code as a hobby, though, so there might still be overlooked issues. Any suggestions are welcome. This series is based on next-20210628, but should apply cleanly on rtc-next too. v4: - Rebased on top of next-20210628 - Added Jiaxun's Tested-by tag for Loongson-2K - Addressed all review comments from v3 - Rewritten field operations with FIELD_GET/FIELD_PREP - Removed all error logs - Removed unnecessary spinlocking (RTC core already protects against concurrent device file operations) v3: - Fixed compile error not discovered after rebase (blame sleep deprivation) - Tested on Loongson-3A4000 (still need testing on Loongson-2K) v2: - Rebased on top of latest linux-next - Updated Huacai's e-mail address to the kernel.org one - Added collected tags - Added adaptation for newly upstreamed Loongson-2K platforms WANG Xuerui (6): rtc: ls2x: Add support for the Loongson-2K/LS7A RTC dt-bindings: rtc: Add bindings for LS2X RTC MIPS: Loongson64: DTS: Add RTC support to LS7A MIPS: Loongson: Enable LS2X RTC in loongson3_defconfig MIPS: Loongson64: DTS: Add RTC support to Loongson-2K MIPS: Loongson: Enable LS2X RTC in loongson2k_defconfig .../devicetree/bindings/rtc/trivial-rtc.yaml | 2 + .../boot/dts/loongson/loongson64-2k1000.dtsi | 5 + arch/mips/boot/dts/loongson/ls7a-pch.dtsi | 5 + arch/mips/configs/loongson2k_defconfig | 1 + arch/mips/configs/loongson3_defconfig | 1 + drivers/rtc/Kconfig | 11 ++ drivers/rtc/Makefile | 1 + drivers/rtc/rtc-ls2x.c | 184 ++++++++++++++++++ 8 files changed, 210 insertions(+) create mode 100644 drivers/rtc/rtc-ls2x.c base-commit: 3579aa488520feeda433ceca23ef4704bf8cd280
