pwm: dwc: split pci out of core driver

2023-10-13T08:07:17+00:00

Moving towards adding non-pci support for the driver, move the pci parts out of the core into their own module. This is partly due to the module_driver() code only being allowed once in a module and also to avoid a number of #ifdef if we build a single file in a system without pci support.

pwm: crc: Allow compilation as module and with COMPILE_TEST

2023-10-13T08:07:17+00:00

The driver compiles just fine as a module. The parent driver's Kconfig symbol already depends on X86 || COMPILE_TEST, so X86 can just be dropped from the dependencies allowing compilation on other platforms than x86.

As part of converting RISC-V SOC_FOO symbols to ARCH_FOO to match the use of such symbols on other architectures, convert the Microchip FPGA PWM driver to use the new symbol. Signed-off-by: Conor Dooley Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

mfd: rz-mtu3: Link time dependencies

2023-08-18T20:48:04+00:00

The new set of drivers for RZ/G2L MTU3a tries to enable compile-testing the individual client drivers even when the MFD portion is disabled but gets it wrong, causing a link failure when the core is in a loadable module but the other drivers are built-in: x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply': pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write' x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable' arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get': rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read' It seems better not to add the extra complexity here but instead just use a normal hard dependency, so remove the #else portion in the header along with the "|| COMPILE_TEST". This could also be fixed by having slightly more elaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper, but in practice it's already possible to compile-test all these drivers by enabling the mtd portion.

The RZ/G2L Multi-Function Timer Pulse Unit 3 (a.k.a MTU3a) uses one counter and two match components to configure duty_cycle and period to generate PWM output waveform. Add basic support for RZ/G2L MTU3a PWM driver by creating separate PWM channels for each IOs. Signed-off-by: Biju Das Reviewed-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.
