| * soc: imx: move PGC handling to a new GPC driverLucas Stach2017-03-081-217/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an almost complete re-write of the previous GPC power gating control code found in the IMX architecture code. It supports both the old and the new DT binding, allowing more domains to be added later and generally makes the driver easier to extend, while keeping compatibility with existing DTBs. As the result, all functionality regarding the power gating controller gets removed from the IMX architecture GPC driver. It keeps only the IRQ controller code in the architecture, as this is closely coupled to the CPU idle implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | The problem described in commit 6befda9a272b ("ARM: i.MX53: globally disable supervisor protect") for the i.MX53 platform applies to i.MX25 as well. E.g. CSPI1+SDMA and SSI1+SDMA are not working with the default AIPS configuration. Modifiy the AIPS configuration to allow access to the bus by SDMA and peripherals.

* | ARM: imx: set correct chip_select in platform setupGreg Ungerer2017-03-203-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platform based configuration setup of spi-imx SPI devices does not set the "chip_select" to the actual hardware chip select used. This works because the cs_gpio mapping that is associated with this platform setup maps the chip_select offset used to the appropriate hardware chip select. The spi-imx driver uses the chip_select as an index into the cs_gpio array and ultimately gets the correct hardware chip select for its hardware setup. The motivation is to be able to eventually modify the spi-imx code to use the "chip_select" directly for harwdare setup instead of indirectly via the cs_gpio mapping array. This change only affects platforms using the hardware chip select addressing method for their SPI devices (sometimes called native chip select). The majority of devices using the spi-imx driver use the GPIO addressing method. The change to use the correct "chip_select" is strait forward. But the cs_gpio mapping arrary also needs to be modifed to match that change. In simple terms the cs_gpio mapping should always have the hardware chip select number at its same index offset. There is no functional change with these patches. The three affected platforms should work exactly as before. However I don't have any of these platforms (or access to them) and so I can't test them. So this patch is compile tested only. Signed-off-by: Greg Ungerer <gerg@linux-m68k.org> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

* ARM/imx/mmcd: Fix broken cpu hotplug handlingThomas Gleixner2016-12-251-12/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cpu hotplug support of this perf driver is broken in several ways: 1) It adds a instance before setting up the state. 2) The state for the instance is different from the state of the callback. It's just a randomly chosen state. 3) The instance registration is not error checked so nobody noticed that the call can never succeed. 4) The state for the multi install callbacks is chosen randomly and overwrites existing state. This is now prevented by the core code so the call is guaranteed to fail. 5) The error exit path in the init function leaves the instance registered and then frees the memory which contains the enqueued hlist node. 6) The remove function is removing the state and not the instance. Fix it by: - Setting up the state before adding instances. Use a dynamically allocated state for it. - Installing instances after the state has been set up - Removing the instance in the error path before freeing memory - Removing the instance not the state in the driver remove callback While at is use raw_cpu_processor_id(), because cpu_processor_id() cannot be used in preemptible context, and set the driver data after successful registration of the pmu.

Moving the exports for assembly code into the assembly files breaks KSYM trimming, but also breaks modversions. While fixing the KSYM trimming is trivial, fixing modversions brings us to a technically worse position that we had prior to the above change: - We end up with the prototype definitions divorsed from everything else, which means that adding or removing assembly level ksyms become more fragile: * if adding a new assembly ksyms export, a missed prototype in asm-prototypes.h results in a successful build if no module in the selected configuration makes use of the symbol. * when removing a ksyms export, asm-prototypes.h will get forgotten, with armksyms.c, you'll get a build error if you forget to touch the file. - We end up with the same amount of include files and prototypes, they're just in a header file instead of a .c file with their exports. As for lines of code, we don't get much of a size reduction: (original commit) 47 files changed, 131 insertions(+), 208 deletions(-) (fix for ksyms trimming) 7 files changed, 18 insertions(+), 5 deletions(-) (two fixes for modversions) 1 file changed, 34 insertions(+) 3 files changed, 7 insertions(+), 2 deletions(-) which results in a net total of only 25 lines deleted.
