FromDaniel Lezcano <daniel.lezcano@linaro.org>

Subject[PATCH 30/69] clocksource/drivers/nomadik_mtu: Add the COMPILE_TEST option
Message-ID<qH4ml-6QB-9@gated-at.bofh.it>
In reply to#1294848
Increase the compilation test coverage by adding the COMPILE_TEST option.

Due to the non portable code for the delay timer, this option is only
available for the ARM architecture.

In reply to#1294848
In order to compile on all arch without error with 'allyesconfig' make
sure the platform selected the GENERIC_CLOCKEVENTS. Without this patch
the new added drivers will prevent the kernel to compile on PARISC.

In reply to#1294848
Increase the compilation test coverage by adding the COMPILE_TEST option.

The driver depends on the common clock framework, thus the dependency added
on COMMON_CLK.

#1294904 — [PATCH 36/69] clocksource/drivers/dw_apb_timer_of: Implement ARM delay timer

FromDaniel Lezcano <daniel.lezcano@linaro.org>
Date2015-12-18 15:40 +0100
Subject[PATCH 36/69] clocksource/drivers/dw_apb_timer_of: Implement ARM delay timer
Message-ID<qH4mn-6QB-51@gated-at.bofh.it>
In reply to#1294848
From: Jisheng Zhang <jszhang@marvell.com>

Implement an ARM delay timer to be used for udelay(). This allows us to
skip the delay loop calibration at boot on Marvell BG2, BG2Q, BG2CD
platforms. And after this patch, udelay() will be unaffected by CPU
frequency changes.

Note: Although in case there are several possible delay timers, we may
not select the "best" delay timer. Take one Marvell Berlin platform for
example: we have arch timer and dw-apb timer. The arch timer freq is
25MHZ while the dw-apb timer freq is 100MHZ, current selection would
choose the dw-apb timer. But the dw apb timer is on the APB bus while
arch timer sits in CPU, the cost of accessing the apb timer is higher
than the arch timer. We could introduce "rating" concept to delay
timer, but this approach "brings a lot of complexity and workarounds
in the code for a small benefit" as pointed out by Daniel.

Later, Arnd pointed out "However, we could argue that this actually
doesn't matter at all, because the entire point of the ndelay()/
udelay()/mdelay() functions is to waste CPU cycles doing not much at
all, so we can just as well waste them reading the timer register
than spinning on the CPU reading the arch timer more often.", so we
just simply register the dw apb base delay timer.
