2010-07-28regulator: tps6507x: allow driver to use DEFDCDC{2,3}_HIGH registerAnuj Aggarwal
Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> In TPS6507x, depending on the status of DEFDCDC{2,3} pin either DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or programmed to change the output voltage. The current driver assumes DEFDCDC{2,3} pins are always tied low and thus operates only on DEFDCDC{2,3}_LOW register. This need not always be the case (as is found on OMAP-L138 EVM). Unfortunately, software cannot read the status of DEFDCDC{2,3} pins. So, this information is passed through platform data depending on how the board is wired.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-05-28mfd: AB3100 register access change to abx500 APIMattias Wallin
The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.

2010-05-25twl6030: regulator: Remove vsel tables and use formula for calculationRajendra Nayak
All twl6030 regulators can be programmed from 1.0v to 3.3v with 100mV steps. The below formula can be used to calculate the vsel values to be programmed in the VREG_VOLTAGE registers. Voltage(in mV) = 1000mv + 100mv * (vsel - 1) Ex: if vsel = 0x9, mV = 1000 + 100 * (9 -1) = 1800mV. This patch removes all existing VSEL tables for twl6030 adjustable regulators and just uses the formula directly for vsel calculations after verifing they fall in the allowed range.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-07mfd: Support 88pm8606 in 860x driverHaojian Zhuang
88PM8606 and 88PM8607 are two discrete chips used for power management. Hardware designer can use them together or only one of them according to requirement. There's some logic tightly linked between these two chips. For example, USB charger driver needs to access both chips by I2C interface. Now share one driver to these two devices. Only one I2C client is identified in platform init data. If another chip is also used, user should mark it in companion_addr field of platform init data. Then driver could create another I2C client for the companion chip. All I2C operations are accessed by 860x-i2c driver. In order to support both I2C client address, the read/write API is changed in below. reg_read(client, offset) reg_write(client, offset, data) The benefit is that client drivers only need one kind of read/write API. I2C and MFD driver can be shared in both 8606 and 8607. Since API is changed, update API in 8607 regulator driver.
