2014-07-02ARM: OMAP2: convert sys_ck and osc_ck to standard clock typesTero Kristo1-69/+0
osc_ck can be simply defined as a multiplexer clock, and the sys_ck can be a simple divider. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2014-05-08ARM: OMAP2+: raw read and write endian fixVictor Kamensky1-4/+4
All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2012-11-12ARM: OMAP2: clock: Cleanup !CONFIG_COMMON_CLK partsRajendra Nayak1-20/+0
Clean all #ifdef's added to OMAP2 clock code to make it COMMON clk ready, not that CONFIG_COMMON_CLK is enabled.

2012-11-12ARM: OMAP2: clock: Convert to common clkRajendra Nayak1-0/+15
Convert all OMAP2 specific platform files to use COMMON clk and keep all the changes under the CONFIG_COMMON_CLK macro check so it does not break any existing code. At a later point switch to COMMON clk and get rid of all old/legacy code.

2012-10-18ARM: OMAP: remove plat/clock.hPaul Walmsley1-2/+0
Remove arch/arm/plat-omap/include/plat/clock.h by merging it into arch/arm/mach-omap1/clock.h and arch/arm/mach-omap2/clock.h. The goal here is to facilitate ARM single image kernels by removing includes via the "plat/" symlink.

2011-03-07OMAP2+: clock: comment that osc_ck/osc_sys_ck should use clockfw autoidle ↵Paul Walmsley1-0/+14
control Place some comments in the OMAP oscillator clock control code to note that its autoidle mode should eventually be controlled via the new OMAP clockfw autoidle control interface.

2010-12-21OMAP2/3: PRCM: split OMAP2/3-specific PRCM code into OMAP2/3-specific filesPaul Walmsley1-1/+1
In preparation for adding OMAP4-specific PRCM accessor/mutator functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was OMAP2xxx/3xxx-specific. This process also requires the #includes in each of these files to be changed to reference the new file name. As part of doing so, add some comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use "sideways includes", to indicate that these users of the PRM/CM includes should not be doing so.

2010-01-28OMAP2xxx clock: move osc_clk code into mach-omap2/clkt2xxx_osc.cPaul Walmsley1-0/+62
Move the osc_clk clock functions from clock2xxx.c to mach-omap2/clkt2xxx_osc. This is intended to make the clock code easier to understand, since all of the functions needed to manage the osc_clk are now located in their own file, rather than being mixed with other, unrelated functions. Clock debugging is also now more finely-grained, since the DEBUG macro can now be defined for osc_clk clocks alone. This should reduce unnecessary console noise when debugging. Also, if at some future point the mach-omap2/ directory is split into OMAP2/3/4 variants, this clkt file can be placed in the mach-omap2xxx/ directory, rather than shared with other chip types that don't use this clock type.
