2013-03-21ARM: shmobile: kzm9g-reference: fix device-tree bindings and device namesGuennadi Liakhovetski2-20/+19
Fix several device-tree bindings, that haven't been updated for newest versions of respective drivers, and device names and pin numbers, left over from non-DT and old pinctrl versions.

2013-03-21ARM: shmobile: kzm9g: add fixed voltage regulators for SDHI0 and SDHI2Guennadi Liakhovetski1-14/+62
Both SDHI0 and SDHI2 power supplies on kzm9g can be switched on and off. In the current version this is not used and the regulators are hard-wired to "on." This patch switches SDHI0 and SDHI2 to proper fixed-voltage regulators, using GPIOs to enable and disable them. Both ports shall now be specifying the MMC_CAP_POWER_OFF_CARD MMC capability. Only SDHI0 has been tested with an SDIO card, since SDHI2 is a microSD slot. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-03-21ARM: shmobile: armadillo800eva: add a fixed voltage regulator for SDHI1Guennadi Liakhovetski1-9/+36
The SDHI1 power supply on armadillo800eva can be switched on and off. In the current version this is not used and the regulator is hard-wired to "on." This patch switches SDHI1 to a proper fixed-voltage regulator, using a GPIO to enable and disable it. Both SDHI0 and SDHI1 ports shall now be specifying the MMC_CAP_POWER_OFF_CARD MMC capability.

2013-03-21ARM: shmobile: sh73a0: move SDHI and MMCIF DT nodes to sh73a0.dtsiGuennadi Liakhovetski3-50/+59
To avoid having to repeat common DT node properties in all .dts files move them to SoC's .dtsi file, setting their status to "disabled." Individual boards will pick up devices, that they want to use and change their DT node status to enabled.

2013-03-21ARM: shmobile: kzm9g: SDHI0 and SDHI1 use a 3.3V power supplyGuennadi Liakhovetski2-12/+10
kzm9g supplies 3.3V to its SDHI0 and SDHI2 interfaces. Specifying 2.8V prevents some (e.g. certain SDIO) cards from working. This patch fixes the voltage and removes redundant OCR masks from platform data. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-03-18ARM: shmobile: kzm9g: correct smsc regulator registrationSimon Horman1-2/+2
Correct the name of smsc devices used for regulator registration allowing the regulators to be found and used. This eliminates the need for CONFIG_REGULATOR_DUMMY when CONFIG_REGULATOR is set. Cc: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

Remove .init_late and .restart from DT_MACHINE_START for kzm9g reference as these are not necessary to bring the board up which is the main aim of kzm9g reference. Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2013-03-18ARM: shmobile: SDHI and MMCIF interfaces to kzm9g-referenceGuennadi Liakhovetski2-3/+75
Add SDHI0 and SDHI2 interfaces to kzm9g-reference. With no pinctrl DT support we cannot use GPIO card-detection and regulator switching. Also update the MMCIF DT node to use all 8 data lines and avoid redundant information in DT.

2013-03-18ARM: shmobile: parse DT and configure pinmux early on kzm9g-referenceGuennadi Liakhovetski1-0/+1
GPIOs can be provided by the pinctrl subsystem, which can be initialised by DT. Therefore DT has to be parsed before requesting GPIOs. Also non-DT pinmux has to be configured early. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-03-18ARM: shmobile: kzm9g: Reference DT implementationSimon Horman5-0/+140
Provide alternate board code for the kzm9g to demonstrate how DT may be used given the current state of driver device tree support. This is intended to act as a reference for mach-shmobile developers. Some notes: * Brings up the GIC interrupt handler using device tree * Brings up the following device using device tree: - MMCIF (MMC) * Does not bring up the INTC interrupt controller at all, thus external devices may not be used. In particular, the SMSC ethernet device may not be used and thus NFS root may not be used. * Uses existing C code and not device tree to initialise the following, which are needed for a working board: - SCIF (Serial) - CMT (Clock) - PFC (GPIO) To use this alternate board code instead of the normal board code, CONFIG_MACH_KZM9G_REFERENCE should be selected in the kernel config. And the sh73a0-kzm9g-reference.dtb flattened device tree blob should be used. Includes fix by Thierry Reding to no longer use gic_handle_irq() Includes fixes by Guennadi Liakhovetski for recent pinmux changes.

2013-03-18ARM: shmobile: streamline mackerel SD and MMC devicesGuennadi Liakhovetski1-56/+57
This patch fixes the following issues with SD and MMC interfaces on mackerel: 1. replace custom card-detection functions with standard GPIO CD API 2. resources don't have to be numbered 3. add SDHI interrupt names 4. remove OCR masks, where regulators are used 5. only specify SDHI CD interrupts on interfaces where a CD pin is present - SDHI0 6. don't instantiate an MMCIF device and initialise MMCIF pins if SDHI1 is selected Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-03-18ARM: shmobile: switch SDHI0 to GPIO regulator on armadillo800evaGuennadi Liakhovetski1-15/+86

Also switch SDHI0 from fixed regulator with hard-wired GPIO levels to a proper GPIO regulator instance to enable dynamic voltage switching.
