2014-05-08ARM: OMAP2+: raw read and write endian fixVictor Kamensky1-1/+1
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.

2013-10-08ARM: OMAP5: id: Remove ES1.0 supportNishanth Menon1-4/+4
OMAP5 ES1.0 was intended as a test chip and has major register level differences w.r.t ES2.0 revision of the chip. All register defines, dts support has been solely added for ES2.0 version of the chip. Further, all ES1.0 chips and platforms are supposed to have been removed from circulation. Hence, there is no need to further retain any resemblence of ES1.0 support in id detection code. Remove the omap_revision handling and BUG() instead to prevent folks who mistakenly try an older unsupported chip and report bogus errors.

2013-10-03ARM: OMAP2+: throw the die id into the entropy poolLinus Walleij1-0/+12
At least eight bytes of this number are totally unique for the device it seems, so this is a perfect candidate for feeding the entropy pool. One byte more or less of constants does not matter so feed in the entire OID struct. This fixes the issue of similar devices initializing to the same state initially. Further registers could be added too, such as OMAP4 CONTROL_STD_FUSE_OPP* and CONTROL_DPLL_NWELL_TRIM* registers, but those vary based on the SoC generation.

Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

2013-05-09ARM: OMAP2+: Remove bogus IS_ERR_OR_NULL checking from id.cTony Lindgren1-3/+2
Commit 6770b211 (ARM: OMAP2+: Export SoC information to userspace) had some broken return value handling as noted by Russell King: + soc_dev = soc_device_register(soc_dev_attr); + if (IS_ERR_OR_NULL(soc_dev)) { + kfree(soc_dev_attr); + return; + } + + parent = soc_device_to_device(soc_dev); + if (!IS_ERR_OR_NULL(parent)) + device_create_file(parent, &omap_soc_attr); This is nonsense. For the first, IS_ERR() is sufficient. For the second, tell me what error checking is required in the return value of this function: struct device *soc_device_to_device(struct soc_device *soc_dev) { return &soc_dev->dev; } when you've already determined that the passed soc_dev is a valid pointer. If you read the comments against the prototype: /** * soc_device_to_device - helper function to fetch struct device * @soc: Previously registered SoC device container */ struct device *soc_device_to_device(struct soc_device *soc); if "soc" is valid, it means the "previously registered SoC device container" must have succeeded and that can only happen if the struct device has been registered. Ergo, there will always be a valid struct device pointer for any registered SoC device container. Therefore, if soc_device_register() succeeds, then the return value from soc_device_to_device() will always be valid and no error checking of it is required. Simples. The rule as ever applies here: get to know the APIs your using and don't fumble around in the dark hoping that you'll get this stuff right. Fix it as noted by Russell.

2012-09-12ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren1-1/+1
As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

The Chip Identification register on the am35x family of SoCs has bits 12, 7:5, and 3:2 marked as reserved and are read as zeroes. Unfortunately, on other omap SoCs, a 0 bit means a feature is "Full Use" so the OMAP3_CHECK_FEATURE() macro called by omap3_check_features() will incorrectly interpret those zeroes to mean that a feature is present even though it isn't. To fix that, the feature bits that are incorrectly set (namely, OMAP3_HAS_IVA and OMAP3_HAS_ISP) need to be cleared after all of the calls to OMAP3_CHECK_FEATURE() in omap3_check_features() are made.

2012-05-10ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xxKevin Hilman1-4/+3
Currently cpu_is_omap3517() actually detects any device in the AM35x family (3517 and no-SGX version 3505.) To make it more clear what is being detected, convert the names from 3517 to AM35xx. This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517(). In order to avoid cross-tree dependencies with clock-tree changes, cpu_is_omap3517() is left until the clock changes are merged, at which point cpu_is_omap3517() will be completely removed.

Pull "ARM: SoC specific updates" from Arnd Bergmann: "These changes are all specific to an soc family or the code for one soc. Lots of work for Tegra3 this time, but also a lot of other platforms. There will be another (smaller) set of soc patches later in the merge window for stuff that has dependencies on external trees or that was sent just before the merge window opened. The asoc tree added a few devices to the i.mx platform, which conflict with other devices added in the same place here.

2012-03-05ARM: OMAP2+: id: Add am33xx SoC type detectionAfzal Mohammed1-0/+2
Determine SoC type, i.e. whether GP or HS Note: cpu_is_34xx() is true for am33xx also. Doing cpu_is_am33xx() check after cpu_is_34xx() will not achieve what we want due to the above reason. Hence cpu_is_am33xx() is done before cpu_is_34xx() Signed-off-by: Afzal Mohammed <afzal@ti.com> Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Add missing break statement in the function omap3xxx_check_revision. The commit id 4390f5b2cb1f56 [ARM: OMAP: TI814X: Add cpu type macros and detection support], removed the 'break' statement from the function omap3xxx_check_revision(), resulting into wrong omap/cpu_revision initialization for AM335x devices.

2011-12-19ARM: OMAP2+: split omap2/3/4_check_revision functionVaibhav Hiremath1-37/+9
We need to detect the SoC revision early, but the SoC feature detection can be done later on. In order to allow further clean-up later on, this patch separates the SoC revision check from the SoC feature check. This patch doesn't change functionality or behavior of the code execution; it barely cleans up the code and splits into SoC specific implementation for Rev ID and feature detection.

2011-12-19ARM: OMAP2+: Make cpu_rev static global variableVaibhav Hiremath1-74/+72
As part of omap revision code cleanup, make cpu_rev variable static global to the file (id.c). This is needed so we can split the SoC detection from SoC feature detection in the following patch. Also move omap3_cpuinfo function a bit as that will be shared by other omap3 like SoCs.

2011-12-13ARM: OMAP: TI81XX: Prepare for addition of TI814X supportHemant Pedanekar1-4/+4
This patch updates existing macros, functions used for TI816X, to enable addition of other SoCs belonging to TI81XX family (e.g., TI814X). The approach taken is to use TI81XX/ti81xx for code/data going to be common across all TI81XX devices. cpu_is_ti81xx() is introduced to handle code common across TI81XX devices. In addition, ti8168_evm_map_io() is now replaced with ti81xx_map_io() and moved in mach-omap2/common.c as same will be used for TI814X and is not board specific.
