mmc: sdhci-pci-core: Disable ES for ASUS BIOS on Jasper Lake

[Andrea Baldoni]

Hello.
I am not subscribed to the list so please CC to my address.

I recently bought a new ASUS Laptop E210KA-GJ059WS with

00:1a.0 SD Host controller: Intel Corporation Device 4dc4 (rev 01) (prog-if 01)
	Subsystem: ASUSTeK Computer Inc. Device 1842
	Flags: bus master, fast devsel, latency 0, IRQ 16, IOMMU group 7
	Memory at 6001129000 (64-bit, non-prefetchable) [size=4K]
	Capabilities: [80] Power Management version 3
	Capabilities: [90] Vendor Specific Information: Len=14 <?>
	Kernel driver in use: sdhci-pci

I tried to install Linux (vanilla kernel 5.19.4) and found that the internal
128GB eMMC SSD was unuseable, unable to make a filesystem on it, dmesg shown

mmc0: running CQE recovery
and
mmc0: cqhci: timeout for tag 0
followed by register dump

(unfortunately I don't have the exact log now).

I found the patch to drivers/mmc/host/sdhci-pci-core.c posted by
Patrick Thompson date Thu, 13 Oct 2022 17:00:17 -0400, and applied it,
but the only way to make the eMMC work was to disable
CQE in its entirety by commenting

slot->host->mmc->caps2 |= MMC_CAP2_CQE;
and
slot->host->mmc->caps2 |= MMC_CAP2_CQE_DCMD;

If someone would like me to do any targeted test to be able to solve the
issue better, I will be happy to do it.

At the moment I am also searching how to get the touchpad to work, I would
appreciate any hint and/or a contact with someone who has experience on
this.

I think the relevant device should be this one, but it doesn't show in
/proc/bus/input/devices.

Thank you.
