Subject: [PATCH v2 1/1] dt-bindings: timer: Add new OST support for the upcoming new driver.
Date: Sat, 17 Oct 2020 00:56:02 +0800 [thread overview]
Message-ID: <20201016165602.55720-2-zhouyanjie@wanyeetech.com> (raw)
In-Reply-To: <20201016165602.55720-1-zhouyanjie@wanyeetech.com>
The new OST has one global timer and two or four percpu timers, so there
will be three combinations in the upcoming new OST driver: the original
GLOBAL_TIMER + PERCPU_TIMER, the new GLOBAL_TIMER + PERCPU_TIMER0/1 and
GLOBAL_TIMER + PERCPU_TIMER0/1/2/3, For this, add the macro definition
about OST_CLK_PERCPU_TIMER0/1/2/3. And in order to ensure that all the
combinations work normally, the original ABI values of OST_CLK_PERCPU_TIMER
and OST_CLK_GLOBAL_TIMER need to be exchanged to ensure that in any
combinations, the clock can be registered (by calling clk_hw_register())
from index 0.
