Subject: [PATCH 0/3] ARM: rockchip: provide the watchdog with a clock
Date: Wed, 21 Jan 2015 20:54:50 +0100 [thread overview]
Message-ID: <1736604.toH3biuFW2@phil> (raw)
The snps,dw-wdt needs to read the clock-rate of its supplying clock
for some operations. The clock itself is based on pclk_pd_alive
and is indeed gateable. The caveat is that the gate is living in the
so-called secure-GRF, which isn't even writeable in some boot-modes.
But to have an actual clock reference to the correct clock, implement
a fixed-factor clock, to be substituted when we can control the actual
gate safely.
