soc: qcom-geni-se: Cleanup the code to remove proxy votes

2021-03-26T14:16:05+00:00

This reverts commit 048eb908a1f2 ("soc: qcom-geni-se: Add interconnect support to fix earlycon crash") ICC core and platforms drivers supports sync_state feature, which ensures that the default ICC BW votes from the bootloader is not removed until all it's consumers are probes. The proxy votes were needed in case other QUP child drivers I2C, SPI probes before UART, they can turn off the QUP-CORE clock which is shared resources for all QUP driver, this causes unclocked access to HW from earlycon. Given above support from ICC there is no longer need to maintain proxy votes on QUP-CORE ICC node from QUP wrapper driver for early console usecase, the default votes won't be removed until real console is probed.

serial: qcom_geni_serial: To correct QUP Version detection logic

2020-09-30T07:12:03+00:00

For QUP IP versions 2.5 and above the oversampling rate is halved from 32 to 16. Commit ce734600545f ("tty: serial: qcom_geni_serial: Update the oversampling rate") is pushed to handle this scenario. But the existing logic is failing to classify QUP Version 3.0 into the correct group ( 2.5 and above). As result Serial Engine clocks are not configured properly for baud rate and garbage data is sampled to FIFOs from the line. So, fix the logic to detect QUP with versions 2.5 and above.

soc: qcom-geni-se: Don't use relaxed writes when writing commands

2020-09-10T16:55:00+00:00

Writing the command is the final step in kicking off a transfer. Let's use writel() to ensure that any other memory accesses are done before the command kicks off. It's expected that this is mostly relevant if we're in DMA mode but since it doesn't appear to regress performance in a measurable way [1] even in PIO mode and it's easier to reason about then let's just always use it. NOTE: this patch came about due to code inspection. No actual problems were observed that this patch fixes. [1] Tested by timing "flashrom -p ec" on a Chromebook which stresses GENI SPI a lot.

tty: serial: qcom-geni-serial: Drop the icc bw votes in suspend for console

2020-07-14T05:43:43+00:00

When using the geni-serial as console, its important to be able to hit the lowest possible power state in suspend, even with no_console_suspend. The only thing that prevents it today on platforms like the sc7180 is the interconnect BW votes, which we certainly don't need when the system is in suspend. So in the suspend handler mark them as ACTIVE_ONLY (0x3) and on resume switch them back to the ALWAYS tag (0x7) Signed-off-by: Rajendra Nayak Reviewed-by: Akash Asthana Tested-by: Matthias Kaehlcke Acked-by: Greg Kroah-Hartman Link: https://lore.kernel.org/r/1594704709-26072-1-git-send-email-rnayak@codeaurora.org Signed-off-by: Bjorn Andersson
