ARM: pxa: fix dm9000 platform data regression

2015-07-16T20:43:59+00:00

Since dm9000 driver added support for a vcc regulator, platform data based platforms have their ethernet broken, as the regulator claiming returns -EPROBE_DEFER and prevents dm9000 loading. This patch fixes this for all pxa boards using dm9000, by using the specific regulator_has_full_constraints() function. This was discovered and tested on the cm-x300 board.

2015-06-23T22:50:46+00:00

Pull clkdev updates from Russell King: "This series addresses some breakage in clkdev caused by a previous patch set from the clk tree which introduced per-user clk structures. This basically renamed the existing 'struct clk' to 'struct clk_hw', and introduced a new 'struct clk'. This change will break anyone using clk_add_alias() with the common clk code enabled. Thankfully, the intersection of users of clk_add_alias() and those using the common clk code is practically zero, but this is something which should be fixed to keep the code sane. The problem is that clk_add_alias() does this: r = clk_get(...); l = clkdev_alloc(r, ...); clk_put(...); which causes the alias to store a pointer to 'r', which has been freed. The original patch set tried to work around this problem incorrectly - at clk_get() time, it tried to convert the struct clk to a struct clk_hw, and then creating a new struct clk from that. Clearly, if the original struct clk has been freed, then we have a use-after-free bug. We have other places in the tree which do something similar, so this series also addresses those locations too. This series addresses this problem by converting clkdev to store and use the clk_hw pointer. This allows clk_get() to only have to create it's per-user struct clk from the clk_hw. We can also get to the desired clk_hw at clk_add_alias() or clk lookup creation time, when the struct clk is "alive". We also perform some cleanups of the code: - replacing looped calls to clkdev_add() with clkdev_add_table() - replacing open-coded lookup allocation (which should have been using clkdev_alloc()) and subsequent clkdev_add() with clkdev_create() - replacing open-coded clk_add_alias() with clk_add_alias()" * 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: clk: s2mps11: use clkdev_create() ASoC: migor: use clkdev_create() ARM: omap2: use clkdev_add_alias() ARM: omap2: use clkdev_create() ARM: orion: use clkdev_create() ARM: lpc32xx: convert to use clkdev_add_table() SH: use clkdev_add_table() clkdev: add clkdev_create() helper clkdev: const-ify connection id to clk_add_alias() clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h clkdev: drop __init from clkdev_add_table() clk: update clk API documentation to clarify clk_round_rate() clkdev: use clk_hw internally

ARM: Show proper respect for Heinrich Hertz by using the correct unit for frequency

2015-05-14T15:22:05+00:00

The SI unit of frequency is Hertz, named after Heinrich Hertz, and is given the symbol "Hz" to denote this. "hz" is not the unit of frequency, and is in fact meaningless. Fix arch/arm to correctly use "Hz", thereby acknowledging Heinrich Hertz' contribution to the modern world.

2015-05-12T21:26:46+00:00

Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework. This transition still enables legacy platforms to run without device tree as before, ie relying on platform data encoded in board specific files. This is the last step of clock framework transition for pxa platforms. It was tested on lubbock (pxa25x), mioa701 (pxa27x) and zylonite (pxa3xx). Signed-off-by: Robert Jarzmik
