Subject: msm8996: sdhci-msm: apq8096-db820c sdhci fails to init - "Timeout waiting for hardware interrupt."
Date: Thu, 10 Oct 2019 16:32:32 +0200 [thread overview]
Message-ID: <20191010143232.GA13560@harukaze> (raw)
Sdhci consistenlty fails to initialize (and thus work) on my apq8096-db820c.
The issue is present since v5.0[*] mainline up to latest v5.4-rc2, using defconfig and:
CONFIG_SCSI_UFS_QCOM=y
CONFIG_PHY_QCOM_QMP=y
CONFIG_PHY_QCOM_UFS=y
CONFIG_ATL1C=y
but can be 100% reproduced with a clean defconfig too.
During boot, when it's time to mount the sdcard, mmc0 spits out a lot of:
...

in between several sdhci register dumps.
Has anyone seen that before? Is sdhci-msm support broken upstream or am i missing
something config-wise?
Full boot logs here: https://pastebin.ubuntu.com/p/BtRrgnjV7J/
*: nothing earlier then v5.0 boots on this board, so i couldn't test it.
