https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/soc Samsung S3C24xx and S3C64xx machine code cleanup for v5.10 Big cleanup for the Samsung S3C24xx and S3C64xx platforms, although it also touches files shared with S5Pv210 and Exynos. This is mostly Arnd Bergmann work which Krzysztof Kozlowski took over, rebased and polished. The goal is to cleanup, merge and finally make the Samsung S3C24xx and S3C64xx architectures multiplatform. The multiplatform did not happen yet here - just cleaning up and merging into one arch/arm/mach-s3c directory. However this is step forward for multiplatform or at least to keep this code still maintainable. This pulls also branch with changes for Samsung SoC sound drivers from broonie/sound because the cleanups there were part of this series and all further patches depend on them. * tag 'samsung-soc-s3c-5.10' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: (62 commits) ARM: s3c: Avoid naming clash of S3C24xx and S3C64xx timer setup ARM: s3c: Cleanup from old plat-samsung include ARM: s3c: make headers local if possible ARM: s3c: move into a common directory ARM: s3c24xx: stop including mach/hardware.h from mach/io.h cpufreq: s3c24xx: move low-level clk reg access into platform code cpufreq: s3c2412: use global s3c2412_cpufreq_setrefresh ARM: s3c: remove cpufreq header dependencies cpufreq: s3c24xx: split out registers fbdev: s3c2410fb: remove mach header dependency ARM: s3c24xx: bast: avoid irq_desc array usage ARM: s3c24xx: spi: avoid hardcoding fiq number in driver ARM: s3c24xx: include mach/irqs.h where needed ARM: s3c24xx: move s3cmci pinctrl handling into board files ARM: s3c24xx: move iis pinctrl config into boards ARM: s3c24xx: move spi fiq handler into platform ARM: s3c: adc: move header to linux/soc/samsung ARM: s3c24xx: move irqchip driver back into platform ARM: s3c24xx: move regs-spi.h into spi driver ARM: s3c64xx: remove mach/hardware.h ...

PWM timer initialization has two independent implementations - one for S3C24xx and one for S3C64xx. The naming however was always the same and before also the declaration was shared.

The s3c2410fb driver is too deeply intertwined with the s3c24xx platform code. Change it in a way that avoids the use of platform header files but having all interface data in a platform_data header, and the private register definitions next to the driver itself. One ugly bit here is that the driver pokes directly into gpio registers, which are owned by another driver. Passing the mapped addresses in platform_data is somewhat suboptimal, but it is a small improvement over the previous version.

The s3c_gpio_cfgall_range() function is an internal interface of the samsung gpio driver and should not be called directly by drivers, so move the iis pin initialization into the boards. This means the pin configuration is only run once at early boot, rather than each time the driver binds, but the effect should be the same. Note that the s3c2412-i2s driver has no boards using it in mainline linux, the driver gets selected for the jive machine but is never instantiated.

2020-08-19ARM: s3c24xx: move spi fiq handler into platformArnd Bergmann3-0/+126
The fiq handler needs access to some register definitions that should not be used directly by device drivers. Since this is closely related to the irqchip driver anyway, move it into the same place.

2020-08-19ARM: s3c: adc: move header to linux/soc/samsungArnd Bergmann7-38/+6
There are multiple drivers using the private adc interface. It seems unlikely that they would ever get converted to iio, so make the current state official by making the header file global. The s3c2410_ts driver needs a couple of register definitions as well.

2020-08-19ARM: s3c24xx: move irqchip driver back into platformArnd Bergmann2-0/+1331
It was a good idea to move it out at first, but the irqchip code is still tightly connected to the s3c24xx platform code and uses multiple internal header files, so just move it back for the time being to avoid those dependencies.

2020-08-19ARM: s3c24xx: move regs-spi.h into spi driverArnd Bergmann4-46/+2
