Re: [PATCH 2/2] pwm: atmel-tcb: fix max time computation for slowclk source
From: Nicolas Ferre
Date: Thu Sep 19 2013 - 03:24:59 EST
On 18/09/2013 17:06, Boris BREZILLON :
Use the the tcb counter width to compute the maximum time that can be
represented using the slow clock source instead of the static 16 bit width.
