2021-12-17bus: mhi: core: Add an API for auto queueing buffers for DL channelManivannan Sadhasivam2-5/+22
Add a new API "mhi_prepare_for_transfer_autoqueue" for using with client drivers like QRTR to request MHI core to autoqueue buffers for the DL channel along with starting both UL and DL channels. So far, the "auto_queue" flag specified by the controller drivers in channel definition served this purpose but this will be removed at some point in future.

2021-12-17bus: mhi: core: Fix race while handling SYS_ERR at power upManivannan Sadhasivam1-23/+12
During SYS_ERR condition, as a response to the MHI_RESET from host, some devices tend to issue BHI interrupt without clearing the SYS_ERR state in the device. This creates a race condition and causes a failure in booting up the device. The issue is seen on the Sierra Wireless EM9191 modem during SYS_ERR handling in mhi_async_power_up(). Once the host detects that the device is in SYS_ERR state, it issues MHI_RESET and waits for the device to process the reset request. During this time, the device triggers the BHI interrupt to the host without clearing SYS_ERR condition. So the host starts handling the SYS_ERR condition again. To fix this issue, let's register the IRQ handler only after handling the SYS_ERR check to avoid getting spurious IRQs from the device.

For whatever reason, some devices like QCA6390, WCN6855 using ath11k are not in M3 state during PM resume, but still functional. The mhi_pm_resume should then not fail in those cases, and let the higher level device specific stack continue resuming process. Add an API mhi_pm_resume_force(), to force resuming irrespective of the current MHI state. This fixes a regression with non functional ath11k WiFi after suspend/resume cycle on some machines.

After making the brcmstb_gisb driver modular with 707a4cdf86e5 ("bus: brcmstb_gisb: Allow building as module") Guenter reported that mips allmodconfig failed to link because board_be_handler was referenced. Thomas indicated that if we were to continue making the brcmstb_gisb driver modular for MIPS we would need to introduce a function that allows setting the board_be_handler and export that function towards modules. This is what is being done here: board_be_handler is made static and is now settable with a mips_set_be_handler() function which is exported.

SRAM driver often returns -EPROBE_DEFER and thus this bus driver often prints error message, even if it probes successfully later.

2021-10-05drivers: bus: simple-pm-bus: Add support for probing simple bus only devicesSaravana Kannan1-3/+39
fw_devlink could end up creating device links for bus only devices. However, bus only devices don't get probed and can block probe() or sync_state() [1] call backs of other devices. To avoid this, probe these devices using the simple-pm-bus driver. However, there are instances of devices that are not simple buses (they get probed by their specific drivers) that also list the "simple-bus" (or other bus only compatible strings) in their compatible property to automatically populate their child devices. We still want these devices to get probed by their specific drivers. So, we make sure this driver only probes devices that are only buses.

Let's add handling the otg force idle quirk for the old omap2430 glue layer used up to omap4 as the musb driver quirk only works if the driver is loaded. Unlike with the am335x glue layer, looks like we don't need the quirk handling for SYSC_QUIRK_REINIT_ON_CTX_LOST. Eventually when all the musb using SoCs are booting with device tree based configuration, we can just remove the related quirk handling from the musb driver.
