2021-01-25drivers: soc: qcom: rpmpd: Add msm8994 RPM Power DomainsKonrad Dybcio3-0/+38
MSM8994 uses similar to MSM8996, legacy-style voltage control, but does not include a VDD_SC_CX line. This setup is also correct for MSM8992. Do note that there exist some boards that use a tertiary PMIC (most likely pm8004), where SMPB on VDDGFX becomes SMPC. I cannot test this configuration though.

2021-01-07soc: qcom: rpmh: Remove serialization of TCS commandsLina Iyer2-14/+17
Requests sent to RPMH can be sent as fire-n-forget or response required, with the latter ensuring the command has been completed by the hardware accelerator. Commands in a request with tcs_cmd::wait set, would ensure that those select commands are sent as response required, even though the actual TCS request may be fire-n-forget. Also, commands with .wait flag were also guaranteed to be complete before the following command in the TCS is sent. This means that the next command of the same request blocked until the current request is completed. This could mean waiting for a voltage to settle or series of NOCs be configured before the next command is sent. But drivers using this feature have never cared about the serialization aspect. By not enforcing the serialization we can allow the hardware to run in parallel improving the performance. Let's clarify the usage of this member in the tcs_cmd structure to mean only completion and not serialization. This should also improve the performance of bus requests where changes could happen in parallel. Also, CPU resume from deep idle may see benefits from certain wake requests.

2020-12-28drivers: qcom: rpmh-rsc: Do not read back the register write on triggerLina Iyer1-1/+1
When triggering a TCS to send its contents, reading back the trigger value may return an incorrect value. That is because, writing the trigger may raise an interrupt which could be handled immediately and the trigger value could be reset in the interrupt handler. A write_tcs_reg_sync() would read back the value that is written and try to match it to the value written to ensure that the value is written, but if that value is different, we may see false error for same.

Since commit 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") we've required that file operation structures explicitly enable splice support, rather than falling back to the default handlers. Most /proc files use the indirect 'struct proc_ops' to describe their file operations, and were fixed up to support splice earlier in commits 40be821d627c..b24c30c67863, but the mountinfo files interact with the VFS directly using their own 'struct file_operations' and got missed as a result. This adds the necessary support for splice to work for /proc/*/mountinfo and friends.
