Linus,

please pull the latest irq/core branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-core-2021-02-15

up to:  0b6d70e571a1: Merge tag 'irqchip-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Updates for the irq subsystem:

  - The usual new irq chip driver (Realtek RTL83xx)
  - Removal of sirfsoc and tango irq chip drivers
  - Conversion of the sun6i chip support to hierarchical irq domains
  - The usual fixes, improvements and cleanups all over the place

Thanks,

	tglx

Linus,

please pull the latest timers/core branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-core-2021-02-15

up to:  11db5710d4a9: Merge tag 'timers-v5.12-rc1' of https://git.linaro.org/people/daniel.lezcano/linux into timers/core

Time and timer updates:

 - Instead of new drivers remove tango, sirf, u300 and atlas drivers
 - Add suspend/resume support for microchip pit64b
 - The usual fixes, improvements and cleanups here and there

Thanks,

	tglx

-ST-Ericsson U300 apptimer

-Required properties:
-
-- compatible : should be "stericsson,u300-apptimer"
-- reg : Specifies base physical address and size of the registers.
-- interrupts : A list of 4 interrupts; one for each subtimer. These
-  are, in order: OS (operating system), DD (device driver) both
-  adopted for EPOC/Symbian with two specific IRQs for these tasks,
-  then GP1 and GP2, which are general-purpose timers.

-Example:
-
-timer {
-	compatible = "stericsson,u300-apptimer";
-	reg = <0xc0014000 0x1000>;
-	interrupts = <24 25 26 27>;
