To avoid using the mach/omap1510.h header file, pass the correct address as platform data.

omapfb calls directly into the omap_set_dma_priority() function in the DMA driver. This prevents compile-testing omapfb on other architectures. Add an inline function next to the other ones for non-omap configurations.

The obsolete camera support was removed, but a few lines remain in this file and cause a warning:

Remove this and all related lines as well.

From: Arnd Bergmann arnd@arndb.de

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.

There is only one board that uses the omap_cf driver, so moving the chipselect configuration there does not lead to code duplication but avoids the use of mach/tc.h in drivers.

The omap usb drivers still rely on mach/*.h headers that are explicitly or implicitly included, but all the required definitions are now in include/linux/soc/ti/, so use those instead and allow compile-testing on other architectures.

The innovator board needs a special case for its phy control.

Move the corresponding code into the board file and out of the common code by adding another callback.

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.

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.

From: Arnd Bergmann arnd@arndb.de

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.

In preparation for conversion of OMAP1 clocks to common clock framework, identify arch/arm/mach-omap1 local users of those clocks and update them to call clk_prepare_enable/clk_disable_unprepare() instead of just clk_enable/disable(), as required by CCF implementation of clock API.

Since its introduction to the mainline kernel, omap1_uart_recalc() helper makes incorrect use of clk->enable_bit as a ready to use bitmap mask while it only provides the bit number. Fix it.

There are some OMAP1 clock code bits that have no effect: - crystal_type variable is set to 0 but never changed, then crystal_type == 2 condition is never true and ck_ref.rate never set to 19200000, - clk->ops->allow_idle() is called from omap_clk_enable_autoidle_all() but that op is not configured for any clock, then the function does nothing and the op field is not needed, - ENABLE_ON_INIT flag is set for some clocks but is never checked by any code, then not needed. Drop that code.

The driver, OMAP1 specific, now omits clk_prepare/unprepare() steps, not supported by OMAP1 custom implementation of clock API. However, non-CCF stubs of those functions exist for use on such platforms until converted to CCF.

Update the driver to be compatible with CCF implementation of clock API.

From: Janusz Krzysztofik jmkrzyszt@gmail.com

OMAP1 still uses its own implementation of standard clock API defined in include/linux/clk.h. Internals of that implementation are not visible outside OMAP1 directory. As a consequence, device drivers are not able to register clocks potentially provided by peripheral devices.

Drop OMAP1 implementation of the clock API and enable common clock framework. Modify the remaining low level code to be compatible with clock provider API and register the clocks with CCF.

Move initialisation of clocks to omap1_timer_init() to avoid memory allocation issues at early setup phase from where omap1_init_early() is called. Register the clocks after initialization of clock I/O registers, local clock pointers used by OMAP1 clock ops, and local .rate fields of clocks with no local implementation of .recalc ops, so CCF structures are populated with correct data during clock registration. Instead of enabling some of the registered clocks, flag them for CCF as critical. Introduce .is_enabled op using code that verifies hardware status of clock enablement, split out from implementation of .disable_unused op, so the latter is actually called by CCF for not requested but hardware enabled clocks. Add .round_rate ops where missing so .set_rate ops are called by CCF as expected. Since CCF allows parallel execution of .enable/.disable and .set_rate ops, protect registers shared among those groups of ops from concurrent access with spinlocks. Drop local debugfs support in favor of that provided by CCF.

v2: flag tc2_ck as CLK_IS_CRITICAL (Aaro) v3: rebase on top of soc/omap1-multiplatform-5.18, - drop no longer needed includes from arch/arm/mach-omap1/io.c

With all the header files out of the way, and the clock driver converted to the common framework, nothing stops us from building OMAP together with the other platforms.

As usual, the decompressor support is a victim here, and is only available when CONFIG_DEBUG_LL is configured for the particular board.
