** Description changed:
[Impact]
On new CML PCH-H platforms, many devices are not correctly probed,
inclusive of touchpad.
[Fix]
New device IDs for CML PCH-H are landed in v5.4-rc1 and linux-next. So
far the known list are:
* 8f05eee67c14: "mmc: sdhci-pci: Add another Id for Intel CML"
* 07f047e3fe33: "i2c: i801: Add support for Intel Comet Lake PCH-H"
* 5a0feb6287e3: "mtd: spi-nor: intel-spi: Add support for Intel Comet
Lake-H SPI serial flash"
* dd047dce3a6f: "mfd: intel-lpss: Add Intel Comet Lake PCH-H PCI IDs"
The first one has been included in v5.4-rc1, while the rest are
currently in linux-next.
[Test Case]
Verify built kernel on platforms with CML PCH-H. Check if intel-lpss
module is loaded, i2c-hid is probed, and so on.
[Regression Potential]
Low. These patches add only new device IDs of previously not probed
devices.
[Other Info]
There 4 patches for OEM-OSP1-B/D/E and only 3 for U because 8f05eee67c14
is already included in U.
