Subject: mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 ms
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=86e488adaab77a733b01e759bf7bfda054479660;p=linux-beck.git

mailbox: arm_mhu: reduce txpoll_period from 10ms to 1 ms

Since the mailbox core users hrtimers now, it can handle much higher
resolutions. We can reduce the txpoll_period to 1 ms as the transmit
usually takes just few microseconds.
