Subject: [PATCH AUTOSEL 4.9 15/23] pwm: bcm2835: Dynamically allocate base
Date: Sat, 18 Apr 2020 10:43:57 -0400 [thread overview]
Message-ID: <20200418144405.10565-15-sashal@kernel.org> (raw)
In-Reply-To: <20200418144405.10565-1-sashal@kernel.org>
From: Florian Fainelli <f.fainelli@gmail.com>
[ Upstream commit 2c25b07e5ec119cab609e41407a1fb3fa61442f5 ]
The newer 2711 and 7211 chips have two PWM controllers and failure to
dynamically allocate the PWM base would prevent the second PWM
controller instance being probed for succeeding with an -EEXIST error
from alloc_pwms().
Fixes: e5a06dc5ac1f ("pwm: Add BCM2835 PWM driver")
