Subject: [PATCH] pwm: bcm2835: Dynamically allocate base
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: 2c25b07e5ec119cab609e41407a1fb3fa61442f5
Patch-mainline: v5.7-rc1
References: bsc#1051510

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().
