[PATCH 1/2] regulator: of: Provide simplified DT parsing method

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Currently regulator drivers which support DT all repeat very similar code to supply a list of known regulator identifiers to be matched with DT, convert that to platform data which is then matched up with the regulators as they are registered. This is both fiddly to get right and for devices which can use the standard helpers to provide their operations is the main source of code in the driver. Since this code is essentially identical for most drivers we can factor it out into the core, moving the identifiers in the match table into the regulator descriptors and also allowing drivers to pass in the name of the subnode to search. When a driver provides an of_match string for the regulator the core will attempt to use that to obtain init_data, allowing the driver to remove all explicit code for DT parsing and simply provide data instead. The current code leaks the phandles for the child nodes, this will be addressed incrementally and makes no practical difference for FDT anyway as the DT data structures are never freed.

[PATCH] asm-generic/io.h: Implement read[bwlq]_relaxed()

by Daniel Thompson

Currently the read[bwlq]_relaxed() family are implemented on every architecture except blackfin, m68k[1], metag, openrisc, s390[2] and score. Increasingly drivers are being optimized to exploit relaxed reads putting these architectures at risk of compilation failures for shared drivers. This patch addresses this by providing implementations of read[bwlq]_relaxed() that are identical to the equivalent read[bwlq](). All the above architectures include asm-generic/io.h . Note that currently only eight architectures (alpha, arm, arm64, avr32, hexagon, microblaze, mips and sh) implement write[bwlq]_relaxed() meaning these functions are deliberately not included in this patch. [1] m68k includes the relaxed family only when configured *without* MMU. [2] s390 requires CONFIG_PCI to include the relaxed family.

[PATCH Resend] cpufreq: cpu0: rename driver and internals to 'cpufreq_dt'

by Viresh Kumar

The naming convention of this driver was always under the scanner, people complained that it should have a more generic name than cpu0, as it manages all CPUs that are sharing clock lines. Also, in future it will be modified to support any number of clusters with separate clock/voltage lines. Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

[PATCH V3 00/10] CPUFreq: cpufreq-cpu0 updates for 3.{17|18 ?}

by Viresh Kumar

Hi Rafael, I am sending this again, but without the controversial part this time. I have dropped last two patches which were about detecting clock sharing among CPUs. Would fix up that later once other Maintainers get in sync about the bindings. So, what's left here ? These are mostly updates/reorders which can be applied the patches which I have dropped now. These are all well reviewed and tested by others. Getting them in shouldn't break anything, I believe. Its better people start using the updates we already have, otherwise they will keep on sending fixes they get (The way Pramod Gurav tried it today). Can we please get them in 3.17 if its still allowed? Or -next otherwise.

[PATCH 3.17-rc3] serial: asc: Adopt readl_/writel_relaxed()

by Daniel Thompson

The architectures where this peripheral exists (ARM and SH) have expensive implementations of writel(), reliant on spin locks and explicit L2 cache management. These architectures provide a cheaper writel_relaxed() which is much better suited to peripherals that do not perform DMA. The situation with readl()/readl_relaxed()is similar although less acute. This driver does not use DMA and will be more power efficient and more robust (due to absense of spin locks during console I/O) if it uses the relaxed variants. This change means the driver is no longer portable and therefore no longer suitable for compile testing.
