As talked about in the patch ("dt-bindings: pinctrl: qcom: tlmm should use output-disable, not input-enable"), using "input-enable" in pinctrl states for Qualcomm TLMM pinctrl devices was either superfluous or there to disable a pin's output. Looking at cheza * ec_ap_int_l, h1_ap_int_odl: Superfluous. The pins will be configured as inputs automatically by the Linux GPIO subsystem (presumably the reference for other OSes using these device trees). * bios_flash_wp_l: Superfluous. This pin is exposed to userspace through the kernel's GPIO API and will be configured automatically. That means that in none of the cases for cheza did we need to change "input-enable" to "output-disable" and we can just remove these superfluous properties.

The l13a rail on trogdor devices has always been intended to be always-on on both S0 and S3. Different trogdor variants use l13a in slightly different ways, but the overall theme is that it's a 1.8V rail that the board uses for things that it wants powered in on S0 and S3. On many boards this includes the boot SPI (AKA qspi). For all intents and purposes this patch is actually a no-op since something else in the system seems to already be keeping the rail on all the time (confirmed via multimeter). That "something else" was postulated to be the modem but the rail is on / stays on even without the modem/wifi coming up so it's likely the boot config. In any case, making the fact that this is always-on explicit seems like a good idea. Signed-off-by:

There are 4 qspi data pins: data0, data1, data2, and data3. Currently we have a shared pin state for data0 and data1 (2 lane config) and a pin state for data2 and data3 (you'd enable both this and the 2 lane state for 4 lanes). The second state is obviously misnamed. Fix it. Fixes: e1ce8539 ("arm64: dts: qcom: sdm845: Add qspi (quad SPI) node") Signed-off-by:

Developers on the ChromeOS team generally want to be notified to review changes that affect Chromebook device tree files. While we could individually add developers, the set of developers and the time each one has available to review patches will change over time. Let's try adding a group list as a reviewer and see if that's an effective way to manage things. A few notes: * Though this email address is actually backed by a mailing list, I'm adding it as "R"eviewer and not "L"ist since it's not a publicly readable mailing list and it's intended just to have a few people on it. This also hopefully conveys a little more responisbility for the people that are part of this group. * I've added all sc7180 and sc7280 files here. At the moment I'm not aware of any non-Chromebooks being supported that use these chips. If later something shows up then we can try to narrow down. * I've added "sdm845-cheza" to this list but not the rest of "sdm845". Cheza never shipped but some developers still find the old developer boards useful and thus it continues to get minimal maintenance. Most sdm845 device tree work, however, seems to be for non-Chromebooks. Cc: Stephen Boyd <swboyd@chromium.org> Cc: Matthias Kaehlcke <mka@chromium.org> Signed-off-by:

Currently, most of the Qualcomm SoCs specify both "iommus" and "iommu-map" properties for the PCIe nodes. First one passes the SMR mask to the iommu driver and the latter specifies the SID for each PCIe device. But with "iommus" property, the PCIe controller will be added to the iommu group along with the devices. This makes no sense because the controller will not initiate any DMA transaction on its own. And moreover, it is not strictly required to pass the SMR mask to the iommu driver. If the "iommus" property is not present, then the default mask of "0" would be used which should work for all PCIe devices. On the other side, if the SMR mask specified doesn't match the one expected by the hypervisor, then all the PCIe transactions will end up triggering "Unidentified Stream Fault" by the SMMU. So to get rid of these hassles and also prohibit PCIe controllers from adding to the iommu group, let's remove the "iommus" property from PCIe nodes. Reported-by:
