Add Aspeed AST2600 PWM/Fan tacho driver. AST2600 has 16 PWM channel and 16 FAN tacho channel. Changes since v2: - declare local function as static function Changes since v1: - fixed review comments - fixed double-looped calculation of div_h and div_l - moving configuration to device tree - register hwmon driver with devm_hwmon_device_register_with_info() Signed-off-by: Troy Lee <redacted> Reported-by: kernel test robot <redacted> --- drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 + drivers/hwmon/aspeed2600-pwm-tacho.c | 756 +++++++++++++++++++++++++++ 3 files changed, 767 insertions(+) create mode 100644 drivers/hwmon/aspeed2600-pwm-tacho.c

Why does this have to be a separate implementation from the existing ASPEED PWM/Tacho driver? Is there really nothing in common?
