ARM: omap1: move mach/*.h into mach directory

2022-04-22T09:08:55Z

Most of the header files are no longer referenced from outside arch/arm/mach-omap1, so move them all to that place directly and change their users to use the new location. The exceptions are: - mach/compress.h is used by the core architecture code - mach/serial.h is used by mach/compress.h The mach/memory.h is empty and gets removed in the process, avoiding the need for CONFIG_NEED_MACH_MEMORY_H.

ARM: omap: remove empty plat-omap directory

2022-04-22T09:08:55Z

The last file in this directory is gone, and it can be removed as well. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap: un-merge plat/sram.c

2022-04-22T09:08:55Z

The sram initialization code is the only shared omap1/2 code that is not a standalone driver, but it is very short. Having two copies of this code means some duplication of the sources, but actually saves object code size as it can be inlined better. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap: split up arch/arm/plat-omap/Kconfig

2022-04-22T09:08:55Z

All the remaining features in here are either omap1 or omap2plus specific, so move them into the respective Kconfig files. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap1: move plat/dma.c to mach/omap-dma.c

2022-04-22T09:08:55Z

Most of the interface functions in plat/dma.c are only used from the USB driver, which is practically OMAP1 specific, except for compile testing. The omap_get_plat_info(), omap_request_dma() and omap_free_dma() functions are never called on omap2 because of runtime checks. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap1: dma: remove omap2 specific bits

2022-04-22T09:08:54Z

No part of plat-omap/dma.c is called on omap2 any more, so anything omap2 specific in here can simply be removed. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap: dma: make usb support optional

2022-04-21T13:01:53Z

Most of the plat-omap/dma.c code is specific to the USB driver. Hide that code when it is not in use, to make it clearer which parts are actually still required. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap: remove debug-leds driver

2022-04-21T13:01:50Z

It has been impossible to select this driver for six years without anyone noticing, so just kill it completely. Fixes: 54ea18e8866a ("ARM: OMAP2+: Remove board file for H4") Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap1: move 32k counter from plat-omap to mach-omap1

2022-04-21T13:01:47Z

omap2 stopped using this code with commit 8d39ff3d1696 ("ARM: OMAP2+: Remove unused legacy code for timer"), so just move it to mach-omap1 now, along with the other half of that driver. Acked-by: Tony Lindgren Signed-off-by: Arnd Bergmann

ARM: omap1: move some headers to include/linux/soc

2022-04-21T13:01:02Z

There are three remaining header files that are used by omap1 specific device drivers: - mach/soc.h provides cpu_is_omapXXX abstractions - mach/hardware.h provides omap_read/omap_write functions and physical addresses - mach/mux.h provides an omap specific pinctrl abstraction This is generally not how we do platform abstractions today, and it would be good to completely get rid of these in favor of passing information through platform devices and the pinctrl subsystem. However, given that nobody is working on that, just move it one step forward by splitting out the header files that are used by drivers today from the machine headers that are only used internally.
