| * mfd: Add missing hunk to change palmas irq to clear on readGraeme Gregory2012-07-091-1/+8
| | | | | | | | | | | | | | | | | | During conversion to regmap_irq this hunk was missing being moved to MFD driver to put the chip into clear on read mode. Also as slave is now set use it to determine which slave for the register call. Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| * mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues.Russ Dill2012-07-091-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' (1fcb57d0) fixes an issue where the ULPI PHYs were not held in reset while initializing the EHCI controller. However, it also changes behavior in omap-usb-host.c omap_usbhs_init by releasing reset while the configuration in that function was done. This change caused a regression on BB-xM where USB would not function if 'usb start' had been run from u-boot before booting. A change was made to release reset a little bit earlier which fixed the issue on BB-xM and did not cause any regressions on 3430 sdp, the board for which the fix was originally made. This new fix, 'USB: EHCI: OMAP: Finish ehci omap phy reset cycle before adding hcd.', (3aa2ae74) caused a regression on OMAP5. The original fix to hold the EHCI controller in reset during initialization was correct, however it appears that changing omap_usbhs_init to not hold the PHYs in reset during it's configuration was incorrect. This patch first reverts both fixes, and then changes ehci_hcd_omap_probe in ehci-omap.c to hold the PHYs in reset as the original patch had done. It also is sure to incorporate the _cansleep change that has been made in the meantime. I've tested this on Beagleboard xM, I'd really like to get an ack from the 3430 sdp and OMAP5 guys before getting this merged. v3 - Brown paper bag its too early in the morning actually run git commit amend fix v2 - Put cansleep gpiolib call outside of spinlock Acked-by: Mantesh Sarashetti <mantesh@ti.com> Tested-by: Mantesh Sarashetti <mantesh@ti.com> Acked-by: Keshava Munegowda <keshava_mgowda@ti.com> Tested-by: Keshava Munegowda <keshava_mgowda@ti.com> Signed-off-by: Russ Dill <Russ.Dill@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| * mfd: mc13xxx workaround SPI hardware bug on i.MxPhilippe Rétornaz2012-07-091-1/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MC13xxx PMIC is mainly used on i.Mx SoC. On those SoC the SPI hardware will deassert CS line as soon as the SPI FIFO is empty. The MC13xxx hardware is very sensitive to CS line change as it corrupts the transfer if CS is deasserted in the middle of a register read or write. It is not possible to use the CS line as a GPIO on some SoC, so we need to workaround this by implementing a single SPI transfer to access the PMIC.

| * mfd: Convert wm831x to irq_domainMark Brown2012-05-204-50/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The modern idiom is to use irq_domain to allocate interrupts. This is useful partly to allow further infrastructure to be based on the domains and partly because it makes it much easier to allocate virtual interrupts to devices as we don't need to allocate a contiguous range of interrupt numbers. Convert the wm831x driver over to this infrastructure, using a legacy IRQ mapping if an irq_base is specified in platform data and otherwise using a linear mapping, always registering the interrupts even if they won't ever be used. Only boards which need to use the GPIOs as interrupts should need to use an irq_base. This means that we can't use the MFD irq_base management since the unless we're using an explicit irq_base from platform data we can't rely on a linear mapping of interrupts. Instead we need to map things via the irq_domain - provide a conveniencem function wm831x_irq() to save a small amount of typing when doing so. Looking at this I couldn't clearly see anything the MFD core could do to make this nicer. Since we're not supporting device tree yet there's no meaningful advantage if we don't do this conversion in one, the fact that the interrupt resources are used for repeated IP blocks makes accessor functions for the irq_domain more trouble to do than they're worth.
