This provides DT binding documentation and device driver. [0]: https://toshiba.semicon-storage.com/ap-en/semiconductor/product/image-recognition-processors-visconti.html Updates: dt-bindings: pwm: Add bindings for Toshiba Visconti PWM Controller v3 -> v4: - No update. v2 -> v3: - Change compatible to toshiba,visconti-pwm - Change filename to toshiba,visconti-pwm.yaml. - Add Reviewed-by tag from Rob. v1 -> v2: - Change SPDX-License-Identifier to GPL-2.0-only OR BSD-2-Clause. - Set compatible toshiba,pwm-visconti only. - Drop unnecessary comments. pwm: visconti: Add Toshiba Visconti SoC PWM support v3 -> v4: - Sorted alphabetically include files. - Changed container_of to using static inline functions. - Dropped unnecessary dev_dbg(). - Drop Initialization of chip.base. - Drop commnet "period too small". - Rebased for-next. v2 -> v3: - Change compatible to toshiba,visconti-pwm. - Fix MODULE_ALIAS to platform:pwm-visconti, again. - Align continuation line to the opening parenthesis. - Rewrite the contents of visconti_pwm_apply() based on the contents suggested by Uwe. v1 -> v2: - Change SPDX-License-Identifier to GPL-2.0-only. - Add prefix for the register defines. - Drop struct device from struct visconti_pwm_chip. - Use '>>' instead of '/'. - Drop error message by devm_platform_ioremap_resource(). - Use dev_err_probe instead of dev_err. - Change dev_info to dev_dbg. - Remove some empty lines. - Fix MODULE_ALIAS to platform:pwm-visconti. - Add .get_state() function. - Use the author name and email address to MODULE_AUTHOR. - Add more comment to function of the hardware. - Support .get_status() function. - Use NSEC_PER_USEC instead of 1000. - Alphabetically sorted for Makefile and Kconfig. - Added check for set value in visconti_pwm_apply().
