+NXP Low Power Timer/Pulse Width Modulation Module (TPM)

+The Timer/PWM Module (TPM) supports input capture, output compare,

+management applications. The counter, compare and capture registers
+are clocked by an asynchronous clock that can remain enabled in low

+Required properties:

+- interrupts :	Should be the clock event device interrupt.
+- clocks :	The clocks provided by the SoC to drive the timer, must contain

[PATCH 2/9] clocksource/drivers/imx-tpm: Add imx tpm timer support

[Daniel Lezcano]

From: Dong Aisheng <aisheng.dong@nxp.com>

IMX Timer/PWM Module (TPM) supports both timer and pwm function while
this patch only adds the timer support. PWM would be added later.

The TPM counter, compare and capture registers are clocked by an
asynchronous clock that can remain enabled in low power modes.

NOTE: We observed in a very small probability, the bus fabric
contention between GPU and A7 may results a few cycles delay
of writing CNT registers which may cause the min_delta event got
missed, so we need add a ETIME check here in case it happened.

[PATCH 3/9] devicetree: bindings: Remove sh7372 CMT binding

[Daniel Lezcano]

From: Magnus Damm <damm+renesas@opensource.se>

Remove the sh7372 CMT compat string to reduce maintenance burden.

It should be fine to break DT compatibility because:
1) The sh7372 SoC support has been removed from upstream
2) The sh7372 CMT DT binding was never part of upstream DTS
3) The CMT driver never matches on the sh7372 binding

[PATCH 4/9] devicetree: bindings: R-Car Gen2 CMT0 and CMT1 bindings

[Daniel Lezcano]

From: Magnus Damm <damm+renesas@opensource.se>

Add documentation for new separate CMT0 and CMT1 DT compatible strings
for R-Car Gen2. These compat strings allow us to enable CMT1-specific
features in the driver. The old compat strings will be deprecated in
the not so distant future.

[PATCH 8/9] devicetree: bindings: Remove deprecated properties

[Daniel Lezcano]

The deprecated DT properties are part of the GIT history,
no need to keep them around any longer.

[PATCH 9/9] clocksource/drivers/bcm2835: Remove message on memory allocation failure

[Daniel Lezcano]

From: Markus Elfring <elfring@users.sourceforge.net>

The bcm2835_timer_init() function emits an error message in case of a memory
allocation failure. This is pointless as the mm core already do that.

Remove this message.

This issue was detected by using the Coccinelle software.

I would prefer to use the wording “for a” instead of “on” in the commit subject.

Does this commit message contain a typo?
Would a wording like “… does that already.” be more appropriate here?

Markus

Hi Thomas,

Rob just point me I missed the patch:

"clocksource: Convert to using %pOF instead of full_name"

Is it ok if I add it in the clockevents/4.14 branch before you pull it ?
