Thanks Matthew.
For the second part of the quirk the device name is incorrect. It should
be r5c832 instead of rl5c832 and the DECLAREs also have the wrong device.
I think it would probably be good to add a printk for an info or debug
message saying that the proprietary controller has been disabled.
After fixing that it compiles correctly and does improve things a lot, but
there are still remaining issues. I suspect these are probably unrelated
to the proprietary controller though.
During suspend I now get:
Suspending console(s) (use no_console_suspend to debug)
pci 0000:00:02.0: PCI INT A disabled
sd 0:0:0:0: [sda] Synchronizing SCSI cache
sd 0:0:0:0: [sda] Stopping disk
ACPI handle has no context!
mmc0: card 8879 removed
MMC: killing requests for dead queue
ACPI handle has no context!
sdhci-pci 0000:02:06.2: PCI INT C disabled
ACPI handle has no context!
ACPI handle has no context!
iwlagn 0000:10:00.0: PCI INT A disabled
[...]
This means that all those register dumps are gone, but I'm not sure about
the "killing requests for dead queue" message.
During resume I get:
sdhci-pci 0000:02:06.2: restoring config space at offset 0xf (was 0x300, writing 0x30a)
sdhci-pci 0000:02:06.2: restoring config space at offset 0x4 (was 0x0, writing 0xe0102000)

sdhci-pci 0000:02:06.2: PCI INT C -> GSI 20 (level, low) -> IRQ 20
mmc0: new SD card at address 8879
mmc mmc0:8879: parent mmc0 should not be sleeping
mmcblk0: mmc0:8879 SU02G 1985024KiB
mmcblk0: p1
The "parent should not be sleeping" message is still there.
All that was still without having a partition mounted. After resume a vfat
partition on the card can be mounted successfully.
I've also tried suspending while a partition on the card (vfat) was
mounted. This gives the same messages during suspend/resume, but reading
from the device after resume fails:
$ ls /mnt/
ls: cannot access /mnt/firmware: Input/output error
firmware
$ ls /mnt/firmware
ls: cannot access /mnt/firmware: Input/output error
(I guess the first command returns "firmware" because that was still
buffered from an 'ls' I did before suspending.)
And in dmesg:
FAT: Filesystem panic (dev mmcblk0p1)
fat_get_cluster: invalid cluster chain (i_pos 0)
File system has been set read-only
Only after unmounting the partition *and* ejecting/reinserting the card
is all well again.
Cheers,
FJP
