2014-05-08ARM: OMAP2+: raw read and write endian fixVictor Kamensky
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.

2013-02-12ARM: OMAP2+: fix some omap_device_build() calls that aren't compiled by defaultPaul Walmsley
Commit c1d1cd597fc77af3086470f8627d77f52f7f8b6c ("ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code") missed a few omap_device_build() calls that aren't included as part of the default OMAP2+ Kconfig, omap2plus_defconfig. Ideally, all devices that are present on the SoC should be created by default, and only the corresponding device driver should be configured or deconfigured in Kconfig. This allows drivers to be built as modules and loaded later, even if they weren't part of the original kernel build. Unfortunately, we're not quite there yet. Thanks to Tony Lindgren for reporting this, found during his randconfig tests. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2013-01-26ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device codePaul Walmsley
Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c. This mostly consists of removing the first attempt at device PM latency handling. This was never really used, has been replaced by the common dev_pm_qos code, and needs to go away as part of the DT conversion. Also, the early platform_device creation code has been removed, as it appears to be unused. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>

2012-10-18ARM: OMAP: Split plat/cpu.h into local soc.h for mach-omap1 and mach-omap2Tony Lindgren
We want to remove plat/cpu.h. To do this, let's first split it to private soc.h to mach-omap1 and mach-omap2. We have to keep plat/cpu.h around until the remaining drivers are fixed, so let's include the local soc.h in plat/cpu.h and for drivers still including plat/cpu.h. Once the drivers are fixed not to include plat/cpu.h, we can remove the file. This is needed for the ARM common zImage support.

2012-10-15ARM: OMAP: SmartReflex: pass device dependent data via platform dataJean Pihet
Remove the device dependent code (ex. cpu_is_xxx()) and settings from the driver code and instead pass them via the platform data. This allows a clean separation of the driver code and the platform code, as required by the move of the platform header files to include/linux/platform_data. Note about the smartreflex functional clocks: the smartreflex fclks are derived from sys_clk and have the same name as the main_clk from the hwmod entry, in order for the SmartReflex driver to request the fclk (using clk_get(dev, "fck")).

Find and unwrap wrapped strings in the style: pr_debug("clockdomain: hardware cannot set/clear wake up of " "%s when %s wakes up\n", clkdm1->name, clkdm2->name); Keeping these strings contiguous seems to be the current Linux kernel policy.

2012-05-31ARM: OMAP2+: SmartReflex: Use per-OPP data structureJean Pihet
The SmartReflex driver incorrectly treats some per-OPP data as data common to all OPPs (e.g., ERRMINLIMIT). Move this data into a per-OPP data structure. Furthermore, in order to make the SmartReflex implementation ready for the move to drivers/, remove the dependency from the SR driver code to the voltage layer by querying the data tables only from the SR device init code.

2012-03-05ARM: OMAP3+: SmartReflex: use voltage domain name in device attributesShweta Gulati
To set sr ntarget values for all volt_domain, volt_table is retrieved by doing a look_up of 'vdd_name' field from omap_hwmod but voltage domain pointer does not belong to omap_hwmod and is not used anywhere else. As a part of voltage layer and SR Layer clean up volt pointer is removed from omap_hwmod and added in dev attributes of SR. The value of the field must match the voltage domain names for the binding to be effective. Tested on OMAP3630 SDP, OMAP3530 Beagleboard and OMAP4430 SDP Board.

2011-09-15OMAP: omap_device: when building return platform_device instead of omap_deviceKevin Hilman
All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.

2011-09-15OMAP2+: voltage: start towards a new voltagedomain layerKevin Hilman
Start cleaning up the voltage layer to have a voltage domain layer that resembles the structure of the existing clock and power domain layers. To that end: - move the 'struct voltagedomain' out of 'struct omap_vdd_info' to become the primary data structure. - convert any functions taking a pointer to struct omap_vdd_info into functions taking a struct voltagedomain pointer. - convert the register & initialize of voltage domains to look like that of powerdomains - convert omap_voltage_domain_lookup() to voltdm_lookup(), modeled after the current powerdomain and clockdomain lookup functions. - omap_voltage_late_init(): only configure VDD info when the vdd_info struct is non-NULL Signed-off-by: Kevin Hilman <khilman@ti.com>

2010-12-22OMAP4: Smartreflex framework extensionsThara Gopinath
This patch extends the smartreflex framework to support OMAP4. The changes are minor like compiling smartreflex Kconfig option for OMAP4 also, and a couple of OMAP4 checks in the smartreflex framework. The change in sr_device.c where new logic has to be introduced for reading the efuse registers is due to the fact that in OMAP4 the efuse registers are 24 bit aligned. A __raw_readl will fail for non-32 bit aligned address and hence the 8-bit read and shift. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
