Subject: [PATCH] MIPS: ath79: add support for QCN550x
Date: Sun, 23 Jan 2022 23:13:31 -0800 [thread overview]
Message-ID: <20220124071329.76057-1-wlooi@ucalgary.ca> (raw)
Adds support for QCN550x, which appears to be very similar to QCA956x.
Signed-off-by: Wenli Looi <wlooi@ucalgary.ca>

Notes:
- OpenWrt pull request: https://github.com/openwrt/openwrt/pull/4271
(contains boot log with stock firmware and with this patch)
- QSDK source: https://source.codeaurora.org/quic/qsdk/oss/system/openwrt/tree/target/linux/ar71xx/patches-3.3/9991-MIPS-ath79-add-SoC-detection-code-for-QCN550X.patch?h=aa/banana
- QSDK clock init appears identical to QCA956x.
- Only tested on QCN5502, not sure if it works for QCN5500.
