[PATCH v8 0/3] RTC support for QEMU RISC-V virt machine

Posted by Anup Patel 6 days ago
This series adds RTC device to QEMU RISC-V virt machine. We have
selected Goldfish RTC device model for this. It's a pretty simple
synthetic device with few MMIO registers and no dependency external
clock. The driver for Goldfish RTC is already available in Linux so
we just need to enable it in Kconfig for RISCV and also update Linux
defconfigs.

We have tested this series with Linux-5.4-rc4 plus defconfig changes
available in 'goldfish_rtc_v2' branch of:
https://github.com/avpatel/linux.git

Changes since v7:
 - Fix broken "stdout-path" in "/chosen" DT node of virt machine

Changes since v6:
 - Rebased on latest QEMU master
 - Addressed all nit comments from Philippe Mathieu-Daude

Changes since v5:
 - Rebased on latest QEMU master
 - Added maintainer entry for Goldfish RTC

Changes since v4:
 - Fixed typo in trace event usage
 - Moved goldfish_rtc.h to correct location

Changes since v3:
 - Address all nit comments from Alistair

Changes since v2:
 - Rebased on RTC code refactoring

Changes since v1:
 - Implemented VMState save/restore callbacks

Thanks.  I've updated the patches on my queue, LMK if there are any more 
changes!
