This includes some cleanups and removal of code, and the final flip of config dependencies - Shmobile has several platforms that are going multiplatform, but this branch also contains a bunch of cleanups that they weren't able to keep separate in a good way.

2015-03-19ARM: shmobile: cpuidle: Remove the pointless default driverDaniel Lezcano1-1/+0
The default idle driver uses one state with the WFI instruction. The default idle routine invokes WFI when no cpuidle driver is present. The default cpuidle driver is pointless and does not give more than the default idle routine and moreover it pulls all the mathematics tied with the cpuidle governor for nothing, hence consuming more energy. Remove the default driver, the related code and register the driver directly.

2015-03-11ARM: shmobile: R-Car Gen2: Add da9063/da9210 regulator quirkGeert Uytterhoeven1-0/+2
The r8a7790/lager and r8a7791/koelsch development boards have da9063 and da9210 regulators. Both regulators have their interrupt request lines tied to the same interrupt pin (IRQ2) on the SoC. After cold boot or da9063-induced restart, both the da9063 and da9210 seem to assert their interrupt request lines. Hence as soon as one driver requests this irq, it gets stuck in an interrupt storm, as it only manages to deassert its own interrupt request line, and the other driver hasn't installed an interrupt handler yet. To handle this, install a quirk that masks the interrupts in both the da9063 and da9210. This quirk has to run after the i2c master driver has been initialized, but before the i2c slave drivers are initialized. As it depends on i2c, select I2C if one of the affected platforms is enabled in the kernel config. On koelsch, the following happens: - Cold boot or reboot using the da9063 restart handler: IRQ2 is asserted, installing da9063/da9210 regulator quirk ... i2c i2c-6: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb i2c 6-0058: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb i2c 6-0058: Detected da9063 i2c 6-0058: Masking da9063 interrupt sources i2c 6-0068: regulator_quirk_notify: 1, IRQC_MONITOR = 0x3fb i2c 6-0068: Detected da9210 i2c 6-0068: Masking da9210 interrupt sources i2c 6-0068: IRQ2 is not asserted, removing quirk - Warm boot (reset button): rcar_gen2_regulator_quirk: IRQ2 is not asserted, not installing quirk Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Tested-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Reviewed-by: Mark Brown <broonie@kernel.org> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

Add Marzen and r8a7779 to CONFIG_SHMOBILE_MULTI. At this point CCF is not yet supported so you cannot run this code yet. For CCF support to happen several different components are needed, and this is one simple portion that moves us forward. Other patches need to build on top of this one. Marzen board support exists in 3 flavours: 1) SHMOBILE_MULTI, MACH_MARZEN - board-marzen-reference.c (CCF + DT) 2) SHMOBILE, MACH_MARZEN_REFERENCE - board-marzen-reference.c (DT) 3) SHMOBILE, MACH_MARZEN - board-marzen.c (legacy C code) When CCF is done then 2) will be removed. When 1) includes same features as 3) then 3) will be removed. Based on work for the Koelsch and r8a7791 by Magnus Damm.
