      parisc/stifb: Implement fb_is_primary_device() · cf936af7
      由 Helge Deller 提交于 
      Implement fb_is_primary_device() function, so that fbcon detects if this
framebuffer belongs to the default graphics card which was used to start
the system.

      ARM: omap1: enable multiplatform · 7036440e
      由 Arnd Bergmann 提交于 
      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.

      ARM: OMAP1: clock: Convert to CCF · c73b9099
      由 Janusz Krzysztofik 提交于 
      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
