[PATCH 0/2] pwm: loongson: Fix PWM configuration handling

From: Keguang Zhang via B4 Relay

Date: Tue Jun 16 2026 - 07:17:29 EST


This series fixes two issues in the Loongson PWM driver:

- Fix the handling of the Low Pulse Buffer Register, which was
incorrectly treated as a duty-cycle register.

- Ensure that PWM configuration updates take effect immediately by
resetting the PWM counter to reload the updated settings.

The fixes were verified on LS1B, LS1C, and LS2K0300 boards.
