Subject[PATCH 00/58] ARM: at91: rework Atmel TCB drivers
Message-ID<tMXlg-4i6-3@gated-at.bofh.it>
Hi,

This series reworks the Atmel Timer counter Block drivers. Those blocks
each have 3 counters with 2 channels each and can be used for
multiple functions:
 - timers
 - PWMs
 - Quadrature decoders
 - Stepper motor counters

Up until now, each TCB was fully used by each driver, possibly wasting
counters/channels.

There is a second issue motivating that rework. Until now, the PIT is
still used to boot then later in the boot sequence, the clocksource is
switched to the TCB. This ends up not working well with preempt-rt
because on some SoCs, the PIT interrupt is shared with the DBGU uart.
When using preempt-rt the interrupt flags for the PIT and the DBGU end
up being incompatible.

The rework breaks the DT ABI. Backward compatibility can be kept by
keeping tcb_clksrc and atmel_tclib but as AVR32 is now gone from the
kernel, I don't think it makes much sense to keep them.

Also, there is no other choice than breaking the mainly unused
pwm-atmel-tcb binding. Only the kizbox is actually using it.

I think the bindings are now ok and I hope we can take the DT changes
for 4.13.

#1653655 — [PATCH 22/58] ARM: dts: at91: at91sam9rl: TC blocks are also simple-mfd and syscon devices

FromAlexandre Belloni <alexandre.belloni@free-electrons.com>
Date2017-05-31 00:10 +0200
Subject[PATCH 22/58] ARM: dts: at91: at91sam9rl: TC blocks are also simple-mfd and syscon devices
Message-ID<tMXuV-4AS-9@gated-at.bofh.it>
In reply to#1653654
Add simple-mfd and syscon to the TC blocks to allow to register one of the
channels as clocksource properly at boot time. It also allows to use regmap
instead of tclib.

Message-ID<tMXuW-4AS-17@gated-at.bofh.it>
In reply to#1653654
Add simple-mfd and syscon to the TC blocks to allow to register one of the
channels as clocksource properly at boot time. It also allows to use regmap
instead of tclib.

#1653672 — [PATCH 26/58] ARM: dts: at91: at91sam9x5: TC blocks are also simple-mfd and syscon devices

FromAlexandre Belloni <alexandre.belloni@free-electrons.com>
Date2017-05-31 00:10 +0200
Subject[PATCH 26/58] ARM: dts: at91: at91sam9x5: TC blocks are also simple-mfd and syscon devices
Message-ID<tMXuX-4AS-49@gated-at.bofh.it>
In reply to#1653654
Add simple-mfd and syscon to the TC blocks to allow to register one of the
channels as clocksource properly at boot time. It also allows to use regmap
instead of tclib.
