2011-12-06ASoC: WM8903: Fix platform data gpio_cfg confusionStephen Warren2-8/+8
wm8903_platform_data.gpio_cfg[] was intended to be interpreted as follows: 0: Don't touch this GPIO's configuration register 1..7fff: Write that value to the GPIO's configuration register 8000: Write zero to the GPIO's configuration register other: Undefined (invalid) The rationale is that platform data is usually global data, and a value of zero means that the field wasn't explicitly set to anything (e.g. because the field was new to the pdata type, and existing users weren't update to initialize it) and hence the value zero should be ignored. 0x8000 is an explicit way to get 0 in the register. The code worked this way until commit 7cfe561 "ASoC: wm8903: Expose GPIOs through gpiolib", where the behaviour was changed due to my lack of awareness of the above rationale. This patch reverts to the intended behaviour, and updates all in-tree users to use the correct scheme. This also makes WM8903 consistent with other devices that use a similar scheme. WM8903_GPIO_NO_CONFIG is also renamed to WM8903_GPIO_CONFIG_ZERO so that its name accurately reflects its purpose.

The SH7372 PM domain initialization routine calls pd_power_up() that executes the domain's .resume() callback, if present, and for the A4R domain this callback attepmts to restore the INTCS state from uninitialized data. To avoid that, introduce __pd_power_up() that will only execute the domain's .resume() callback if its second argument is 'true' and make the SH7372 PM domain initialization use it with 'false' as its second argument.

setup_processor copies the arch_name and elf_name fields out of the selected proc_info_list into two fixed size buffers. Since the proc_info_list structure is defined in a proc_*.S assembly file, this can lead to subtle errors if the strings defined there are too long (for example, corrupting the machine ID).

The following commits break cpuidle on SH-Mobile ARM: 46bcfad cpuidle: Single/Global registration of idle states e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state This patch remedies these issues by up-porting the SH-Mobile code to fit with the above introduced framework changes. It is worth noting that the new code becomes significantly cleaner, so these framework changes are very welcome. At the same time this breakage could probably have been avoided by grepping for "last_state" and "cpuidle_register_driver".

2011-11-11drivers: sh: Generalize runtime PM platform stub.Paul Mundt2-68/+1
The runtime PM platform support stub in use by ARM-based SH/R-Mobile platforms contains nothing that's specifically ARM-related and instead of wholly generic to anything using the clock framework. The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.

2011-11-09arm/tegra: Don't create duplicate gpio and pinmux devicesStephen Warren5-10/+25
*_pinmux_init() register the GPIO and pinmux devices so that they're ready before any other device needs them. *_pinmux_init() are also called by board-dt.c in order to set up the GPIO and pinmux configurations. In this case, if we register the devices, they end up being probed once due to this registration, and a second time due to a device-tree node (or vice-versa). The second probe fails since the memory regions are already requested. Besides, we don't actually want the duplicated devices. To avoid this duplicate registration, modify *_pinmux_init() to check whether it's running on a DT machine. If not, register the pinmux devices. If so, don't register them. Finally, modify board-dt.c to call the *_pinmux_init() after all devices have been instantiated from device-tree. This allows the GPIO and pinmux devices to be instantiated and initialized before calling functions to configure the hardware. This has one disadvantage: The pinmux and GPIO initialization now happens after /all/ devices are instantiated, rather than after just gpio and pinmux but before anything else. So the correct HW configuration is not in place when e.g. the SD/MMC device is probed. Long-term, this should be solved by doing both: a) Initializing the HW state from DT nodes during GPIO and pinmux device probe. b) Using the deferred driver probe mechanism, so that drivers can defer their probe until after the gpio and pinmux drivers have probed. v2: s/int is_dt/bool is_dt/ v3: Use of_machine_is_compatible inside *_pinmux_init() rather than passing an explicit parameter into the function from outside.
