pwm: pxa: Enable for MMP platform

The PXA168, which is part of the MMP platform, also uses this driver. Signed-off-by: Doug Brown Acked-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221113233639.24244-7-doug@schmorgal.com Signed-off-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: jz4740: Depend on MACH_INGENIC instead of MIPS

2022-11-29T12:05:41+00:00

The MACH_INGENIC Kconfig option will be selected when building a kernel targeting Ingenic SoCs, but also when compiling a generic MIPS kernel that happens to support Ingenic SoCs. Therefore, if MACH_INGENIC is not set, we know that we're not even trying to build a generic kernel that supports these SoCs, and we can hide the options to compile the SoC-specific drivers.

pwm: jz4740: Force dependency on Device Tree

2022-11-29T12:05:40+00:00

Ingenic SoCs all require CONFIG_OF, so there is no case where we want to use this driver without CONFIG_OF. Signed-off-by: Paul Cercueil Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: Add clock based PWM output driver

2022-07-29T11:41:18+00:00

Some systems have clocks exposed to external devices. If the clock controller supports duty-cycle configuration, such clocks can be used as pwm outputs. In fact PWM and CLK subsystems are interfaced with in a similar way and an "opposite" driver already exists (clk-pwm). Add a driver that would enable pwm devices to be used via clk subsystem.

pwm: Add support for Xilinx AXI Timer

2022-04-22T16:30:44+00:00

This adds PWM support for Xilinx LogiCORE IP AXI soft timers commonly found on Xilinx FPGAs. At the moment clock control is very basic: we just enable the clock during probe and pin the frequency. In the future, someone could add support for disabling the clock when not in use. Some common code has been specially demarcated. While currently only used by the PWM driver, it is anticipated that it may be split off in the future to be used by the timer driver as well. This driver was written with reference to Xilinx DS764 for v1.03.a [1].
