Hi all: This patchset introduce a generic PWM framework driver for Loongson family. Each PWM has one pulse width output signal and one pulse input signal to be measured. It can be found on Loongson-2K series cpus and Loongson LS7A bridge chips. Thanks. ------- V3: patch (1/2): - Add Reviewed-by tag from Krzysztof, thanks. patch (2/2): - Several code stlye adjustments, such as line breaks. Link to V2: https://lore.kernel.org/all/cover.1712732719.git.zhoubinbin@xxxxxxxxxxx/ v2: - Remove the dts-related patches and update dts at once after all relevant drivers are complete. patch (1/2): - The dt-binding filename should match compatible, rename it as loongson,ls7a-pwm.yaml; - Update binding description; - Add description for each pwm cell; - Drop '#pwm-cells' from required, for pwm.yaml makes it required already.
