SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

pwm: Add driver for cadence TTC TTC has three modes of operations. Timer, PWM and input counters. There is already driver for timer under CADENCE_TTC_TIMER which is used for ZynqMP R5 configuration. This driver is targeting PWM which is for example configuration which can be used for fan control. The driver has been tested on Xilinx Kria SOM platform where fan is connected to one PL pin. When TTC output is connected via EMIO to PL pin TTC pwm can be configured and tested for example like this: pwm config 0 0 10000 1200 pwm enable 0 0 pwm config 0 0 10000 1400 pwm config 0 0 10000 1600 Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Sean Anderson <sean.anderson@seco.com> Link: https://lore.kernel.org/r/915a662ddb88f7a958ca1f307e8fea59af9d7feb.1634303847.git.michal.simek@xilinx.com

pwm: Add a driver for Chrome OS EC PWM This PWM is used in rk3399-gru-bob and rk3399-gru-kevin to control the display brightness. We can only change the duty cycle, so on set_config() we just try to match the duty cycle that dividing duty_ns by period_ns gives us. To disable, we set the duty cycle to zero while keeping the old value for when we want to re-enable it. The cros_ec_set_pwm_duty() function is taken from Depthcharge's cros_ec_set_bl_pwm_duty() but modified to use the generic pwm type. The driver itself is very loosely based on rk_pwm.c for the general pwm driver structure. The devicetree binding file is from Linux, before it was converted to YAML at 5df5a577a6b4 ("dt-bindings: pwm: Convert google,cros-ec-pwm.txt to YAML format") in their repo.

pwm: Add driver for Amlogic Meson PWM controller This adds the driver for the PWM controller found in the Amlogic SoCs. This PWM is only a set of Gates, Dividers and Counters: PWM output is achieved by calculating a clock that permits calculating two periods (low and high). The counter then has to be set to switch after N cycles for the first half period. The hardware has no "polarity" setting. This driver reverses the period cycles (the low length is inverted with the high length) for PWM_POLARITY_INVERSED. Disabling the PWM stops the output immediately (without waiting for the current period to complete first). Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
