Subject: pwm: loongson: Fix LOONGSON_PWM_FREQ_DEFAULT
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=75604e9a5b60707722028947d6dc6bdacb42282e;p=users%2Fhch%2Fmisc.git

pwm: loongson: Fix LOONGSON_PWM_FREQ_DEFAULT

Per the 7A1000 and 7A2000 user manual, the clock frequency of their
PWM controllers is 50 MHz, not 50 kHz.

Fixes: 2b62c89448dd ("pwm: Add Loongson PWM controller support")
