* mfd: omap-usb-host: Fix dts probe of childrenTony Lindgren2018-09-111-5/+6
| | | | | | | | | | | | | | It currently only works if the parent bus uses "simple-bus". We currently try to probe children with non-existing compatible values. And we're missing .probe. I noticed this while testing devices configured to probe using ti-sysc interconnect target module driver. For that we also may want to rebind the driver, so let's remove __init and __exit.

| | | | | | | | | | | | | single-ulpi-bypass is a flag used for older OMAP3 silicon. The flag when set, can excite code that improperly uses the OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit. Instead it clears all of the other bits disabling all of the ports in the process.

| | | | | | | | | | | | | | | | All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

* 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earlier which fixed the issue on BB-xM and did not cause any regressions on 3430 sdp, the board for which the fix was originally made.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>

| | | | | | | | | | | | | | | | | | | It is observed that the echi ports of 3430 sdp board are not working due to the random timing of programming the associated GPIOs of the ULPI PHYs of the EHCI for reset. If the PHYs are reset at during usbhs core driver, host ports will not work because EHCI driver is loaded after the resetting PHYs. The PHYs should be in reset state while initializing the EHCI controller. The code which does the GPIO pins associated with the PHYs are programmed to reset is moved from the USB host core driver to EHCI driver.
