Pull RTC updates from Alexandre Belloni:
"Not much this cycle apart from the ingenic rtc driver rework.
The fixes are mainly minor issues reported by coccinelle rather than
real world issues.
Subsystem:
- new VL flag for backup switch over
Drivers:
- ingenic: only support device tree
- pcf2127: report battery switch over, handle nowayout"

Pull arch/sh updates from Rich Felker:
"Fix for arch/sh build regression with newer binutils, removal of SH5,
fixes for module exports, and misc cleanup"
* tag 'sh-for-5.8' of git://git.libc.org/linux-sh:
sh: remove sh5 support
sh: add missing EXPORT_SYMBOL() for __delay
sh: Convert ins[bwl]/outs[bwl] macros to inline functions
sh: Convert iounmap() macros to inline functions
sh: Add missing DECLARE_EXPORT() for __ashiftrt_r4_xx
sh: configs: Cleanup old Kconfig IO scheduler options
arch/sh: vmlinux.scr
sh: Replace CONFIG_MTD_M25P80 with CONFIG_MTD_SPI_NOR in sh7757lcr_defconfig
sh: sh4a: Bring back tmu3_device early device
sh5 never became a product and has probably never really worked.
Remove it by recursively deleting all associated Kconfig options
and all corresponding files.

In IRQ handler, ONLY clock enable/disable is called due to
clock prepare can NOT be called in interrupt context, but
clock enable/disable will return failure if prepare count
is 0, to fix this issue, just make SNVS clock always prepared
there, the SNVS clock has no prepare function implemented,
so it won't impact anything.

The regulator register specifies how many input clock cycles (minus one)
are contained in one tick of the 1 Hz clock.
Since this register can contain bogus values after the system boots, it
needs to be reset in the probe register, otherwise the RTC may count way
to slow or way too fast.

In function mc13xxx_rtc_probe, the mc13xxx_unlock() is called
before rtc_register_device(). But in the error path of
rtc_register_device(), the mc13xxx_unlock() is called again,
which causes a double-unlock problem. Thus add a call of the
function “mc13xxx_lock” in an if branch for the completion
of the exception handling.
Fixes: e4ae7023e1 ("rtc: mc13xxx: set range")
