Hi,
just for clarification:
This changes user-space representation from
/sys/class/rtc/rtcN/device/{atrim,dtrim,usr}
to
/sys/class/rtc/rtcN/{atrim,dtrim,usr}
and fixes the "mistake made back in 2006" you mention in

correct?

devm semantics arrange for resources to be torn down when

This timer is used by SMP system and use mfcr/mtcr instruction
to access the regs.
Changelog:
- Remove #define CPUHP_AP_CSKY_TIMER_STARTING
- Add CPUHP_AP_CSKY_TIMER_STARTING in cpuhotplug.h
- Support csky mp timer alpha version.
- Just use low-counter with 32bit width as clocksource.

The Hexagon v5 ADSP driver is used for more than only the ADSP and
there's an upcoming non-PAS ADSP PIL for SDM845, so rename the driver to
qcom_q6v5_pas in order to better suite this.

The qcom_q6v5_pil implements support for the self-authenticating modem
subsystem. With the introduction of other q6v5 based non-TZ based
remoteproc driver the current name is cause for confusion, so rename it
to be more specific.

As we're introducing a non-TZ based remoteproc driver for the ADSP in SDM845
the current naming scheme becomes cumbersome. Rename the existing drivers in
order to allow for the following:
qcom_q6v5_adsp - handle the non-TZ adsp subsystem
qcom_q6v5_mss - handles the self-authenticated modem
qcom_q6
- Irq-csky-mpintc is C-SKY smp system interrupt controller and it
could support 16 soft irqs, 16 private irqs, and 992 max common
irqs.
Changelog:
- Move IPI_IRQ into the driver
- Remove irq_set_default_host() and use set_ipi_irq_mapping()
- Change name with upstream feed-back
