2023-03-15soc: qcom: llcc: Do not create EDAC platform device on SDM845Manivannan Sadhasivam
The platforms based on SDM845 SoC locks the access to EDAC registers in the bootloader. So probing the EDAC driver will result in a crash. Hence, disable the creation of EDAC platform device on all SDM845 devices. The issue has been observed on Lenovo Yoga C630 and DB845c. While at it, also sort the members of `struct qcom_llcc_config` to avoid any holes in-between.

2023-03-15qcom: llcc/edac: Support polling mode for ECC handlingManivannan Sadhasivam
Not all Qcom platforms support IRQ mode for ECC handling. For those platforms, the current EDAC driver will not be probed due to missing ECC IRQ in devicetree. So add support for polling mode so that the EDAC driver can be used on all Qcom platforms supporting LLCC. The polling delay of 5000ms is chosen based on Qcom downstream/vendor driver.

2023-03-15qcom: llcc/edac: Fix the base address used for accessing LLCC banksManivannan Sadhasivam
The Qualcomm LLCC/EDAC drivers were using a fixed register stride for accessing the (Control and Status Registers) CSRs of each LLCC bank. This stride only works for some SoCs like SDM845 for which driver support was initially added. But the later SoCs use different register stride that vary between the banks with holes in-between. So it is not possible to use a single register stride for accessing the CSRs of each bank. By doing so could result in a crash. For fixing this issue, let's obtain the base address of each LLCC bank from devicetree and get rid of the fixed stride. This also means, there is no need to rely on reg-names property and the base addresses can be obtained using the index. First index is LLCC bank 0 and last index is LLCC broadcast. If the SoC supports more than one bank, then those need to be defined in devicetree for index from 1..N-1.

2023-02-06soc: qcom: stats: Populate all subsystem debugfs filesStephen Boyd
This driver relies on SMEM to populate items for each subsystem before the device probes. The items in SMEM that are being looked for are populated by the subsystems lazily, and therefore may not exist until the device has booted. For example, if I build this driver into the kernel on Trogdor Lazor and boot up, I don't see a 'modem' debugfs file populated, because the modem boots and populates the SMEM item after this driver probes. Always populate the files for the subsystems if they're in SMEM, and make the qcom_subsystem_sleep_stats_show() function return 0 if the SMEM items still isn't there. This way we can run a simple command like grep ^ /sys/kernel/debug/qcom_stats/* and collect the subsystem sleep stats without interspersed errors or missing details entirely because this driver probed first.

2023-02-04soc: qcom: pmic_glink: Introduce altmode supportBjorn Andersson
With the PMIC GLINK service, the host OS subscribes to USB-C altmode messages, which are sent by the firmware to notify the host OS about state updates and HPD interrupts. The pmic_glink_altmode driver registers for these notifications and propagates the notifications as typec_mux, typec_switch and DRM OOB notifications as necessary to implement DisplayPort altmode support.

2023-02-04soc: qcom: pmic_glink: Introduce base PMIC GLINK driverBjorn Andersson
The PMIC GLINK service runs on one of the co-processors of some modern Qualcomm platforms and implements USB-C and battery managements. It uses a message based protocol over GLINK for communication with the OS, hence the name. The driver implemented provides the rpmsg device for communication and uses auxiliary bus to spawn off individual devices in respective subsystem. The auxiliary devices are spawned off from a platform_device, so that the drm_bridge is available early, to allow the DisplayPort driver to probe even before the remoteproc has spun up.
