* ENGR00309031-2 dts: imx6sx-sdb-emmc: add emmc support on uSDHC4Dong Aisheng2014-04-17
| | | | | | | | | The eMMC interface is shared with uSDHC4 BOOT card slot and the eMMC chip is DNP by default. User needs burn the eMMC chip onto the board manually and do hw rework to enable eMMC signals. We create a new dts imx6sx-sdb-emmc.dts for easy eMMC test after doing hw rework.

* ENGR00309031-1 dts: imx6sx-sdb: move usdhc4 gpios pins out of hog groupDong Aisheng2014-04-17
| | | | | | | | | | | | | | For imx6sx sdb board, the eMMC interface and uSDHC4 BOOT card slot are shared and the eMMC chip is DNP by default. If burn the eMMC chip onto the board and do hw rework to enable eMMC signals, the cd-gpio and wp-gpios will be reused as eMMC DATA signals. So we'd better move this two gpio pin out of hog group for easy disable this gpio setting in another dts. It's required for the next patch which adds the eMMC support in another dts file.

* usb: phy: make PHY driver selection possible by controller driversRoger Quadros2014-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert PHY Drivers from menuconfig to menu so that the PHY drivers can be explicitely selected by the controller drivers. USB_PHY is no longer a user visible option. It is upto to the PHY drivers to select it if needed. This patch does so for the existing PHY drivers that use the USB_PHY library. Doing so moves the USB_PHY and PHY driver selection problem from the end user to the PHY and controller driver developer. e.g. Earlier, a controller driver (e.g. EHCI_OMAP) that needs to select a PHY driver (e.g. NOP_PHY) couldn't do so because the PHY driver depended on USB_PHY. Making the controller driver depend on USB_PHY has a negative effect i.e. it becomes invisible to the user till USB_PHY is enabled. Most end users will not familiar with this. With this patch, the end user just needs to select the controller driver needed for his/her platform without worrying about which PHY driver to select. Also update USB_EHCI_MSM, USB_LPC32XX and USB_OMAP to not depend on USB_PHY any more. They can safely select the necessary PHY drivers. [ balbi@ti.com : refreshed on top of my next branch.

* ARM: dts: imx6sl-evk: Keep VGEN1 regulator always enabledFabio Estevam2014-04-16
| | | | | | | | | | | | | | | | | | | On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1P2V domain of the imx6sl SoC, so we need to keep it always powered. According to imx6sl datasheet the GPIO block has three supplies: NVCC33_IO, NVCC18_IO and NVCC_1P2V and it states that: "All digital I/O supplies (NVCC_xxxx) must be powered under normal conditions whether the associated I/O pins are in use or not" This problem has been observed by the fact that a GPIO connected to an LED could not work when the PMIC driver was enabled. Keeping VGEN1 regulator always enabled fixes the problem.

* ENGR00308382-2 mcc: enable mcc a9 linux demoRichard Zhu2014-04-16

* ENGR00308382-1 mcc: add a9 linux mcc_demo driverRichard Zhu2014-04-16
| | | | | | | | | | | | | | | - based on sema4 driver, mcc stack, add the mcc_demo driver by sysfs. - mcc pingpong demo - mcc can demo NOTE: - rdc should be disabled in m4 mqx side, otherwise, a9 linux would fail to mount rootfs. - add the m4 related clks at linux side, because that the m4's clks would be turned off/on during linux boot up if they are not added at linux clk definitions.

* ENGR00308060-3 mcc: add sema4 driver required by mccRichard Zhu2014-04-16
| | | | | | | | - add linux sema4 driver, that mandatory required by mcc. - use volatile types in sema4 structure - align the port definiton a9 is 1, m4 is 2. Signed-off-by: Richard Zhu <r65037@freescale.com>
* ENGR00308060-2 mcc: implementation mcc on imx6sxRichard Zhu2014-04-16
| | | | | | | | | | | | | | | | | | | - inherited mcc ver 001.002 from vibryd mqx release. - use mu general int4 as the cpu2cpu int (num is 122 at a9 side). - add linux wait_event/wake_up mechanism on the buffer management of share memory - replace wait_event_interruptible### by wait_event###, so the sleep task wouldn't be waken up by reboot or CTRL+C signals. - use the offset address to do the MQX_TO_VIRT and VIRT_TO_MQX exchanges. - regmap_bits_updat can't write 1 to clear the bit-set asr, use regmap_read/write - fix mu irq clear hang issue only do the regmap once in the isr register func, and replace the multi-regmap operations in the kinds of mx6sx mcc related apis by one global imx_mu_reg.

* ENGR00308060-1 mcc: implementation mcc common on imx6sxRichard Zhu2014-04-16
| | | | | | | | | | | | | - inherited mcc ver 001.002 from vibryd mqx release. - let lwevent related codes mqx specified. - use the offset address to do the MQX_TO_VIRT and VIRT_TO_MQX exchanges. - add some modification in mcc common codes, since all the shm access should be protected by sema4. - double check the list head, and make the recv more robust.
