This patch fixes conflict between commit 8ae3559 "mfd: mc13xxx workaround SPI hardware bug on i.Mx" and commit 10c7a5d "mfd: Use devm_* APIs for mc13xxx". commit 8ae3559 changes regmap_init_spi to regmap_init. So now we need to use devm_regmap_init rather than devm_regmap_init_spi. Signed-off-by: NAxel Lin <axel.lin@gmail.com> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

'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earlier which fixed the issue on BB-xM and did not cause any regressions on 3430 sdp, the board for which the fix was originally made.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: NMantesh Sarashetti <mantesh@ti.com> Tested-by: NMantesh Sarashetti <mantesh@ti.com> Acked-by: NKeshava Munegowda <keshava_mgowda@ti.com> Tested-by: NKeshava Munegowda <keshava_mgowda@ti.com> Signed-off-by: NRuss Dill <Russ.Dill@gmail.com> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

Since none of the users now reference the cache directly we can happily remove the custom cache code and rely on the regmap cache. For simplicity we don't bother with the register defaults tables but instead read the defaults from the device - regmap is capable of doing this, unlike our old cache infrastructure. This saves a lot of code and allows us to cache the device revision information too.

Hierarchically, the AB8500 is a child of the DB8500 PRCMU. So now that Device Tree is being used and MFD core code is Device Tree aware, we can simply register DB8500 PRCMU from Device Tree in the normal way then allow the DB8500 PRCMU driver to register the AB8500 as a simple MFD device at probe time.

During Device Tree enablement of the ab8500 and db8500-prcmu drivers, a decision was made to omit registration through the MFD API and use Device Tree directly. However, because MFD devices have a different address space and the ab8500 and db8500 both use I2C to communicate, this causes issues with address translation during execution of of_platform_populate(). So the solution is to make the MFD core aware of Device Tree and have it assign the correct node pointers instead. To make this work the MFD core also needs to be awere of IRQ domains, as Device Tree insists on IRQ domain compatibility. So, instead of providing an irq-base via platform code, in the DT case we simply look up the IRQ domain and map to the correct virtual IRQ.

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.

We already use them for openat() and friends, but fchdir() also wants to be able to use O_PATH file descriptors. This should make it comparable to the O_SEARCH of Solaris.
