Follow reviewers's comments: - derive the number of PWMs from the specific compatible string 2. Add mt7629 pwm description 3. Add mt7628 fixed-clock description Changes since v9: 1. PATCH 03/11: Add an Acked-by tag Changes since v8: 1. Fix warning and build-error for patch 04/11 Changes since v7: 1. PATCH v7 10/11: Add a missed Reviewed-by tag Changes since v6: 1. Due to we can use fixed-clock in DT We removed has_clks and fixed-clock properties Changes since v5: - Follow reviewer's comments: 1. the license stuff is a separate change 2. split fix mt7628 pwm into a single patch 3. to ensure to not use mtk_pwm_clk_name[10] (After dynamic allocate clock array patch, this is no need to check) 4. Use clock-frequency property to replace the use of has_clks Changes since v4: - Follow reviewer's comments (v3: pwm: mediatek: add a property "num-pwms") Move the changes of droping the check for of_device_get_match_data returning non-NULL to next patch - Follow reviewers's comments (v3: pwm: mediatek: allocate the clks array dynamically) 1. use pc->soc->has_clks to check clocks exist or not. 2. Add error message when probe() unable to get clks - Fixes bug when SoC is old mips which has no complex clock tree. if clocks not exist, use the new property from DT to apply period calculation; otherwise, use clk_get_rate to get clock frequency and apply period calculation. Changes since v3: - add a new property "clock-frequency" and fix mt7628 pwm - add mt7629 pwm support Changes since v2: - use num-pwms instead of mediatek,num-pwms. - rename the member from num_pwms to fallback_num_pwms to make it more obvious that it doesn't represent the actually used value. - add a dev_warn and a expressive comment to help other developers to not start adding num_pwms in the compatible_data. Changes since v1: - add some checks for backwards compatibility.
