* mtd: ubi: Fix scrubbing during attachSascha Hauer2016-10-113-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | ensure_wear_leveling() is called at the end of ubi_wl_init() and may come to the decision to scrub some blocks. In the Kernel this is done in a separate thread, but in barebox we do this synchronously. The problem is that during ubi_wl_init() the EBA system is not yet initialized (ubi_eba_init() is not yet called), so the wear level worker hits a NULL pointer deref when the fastmap needs to be updated and ubi_write_fastmap() accesses vol->eba_tbl. Solve this by honoring the ubi->thread_enabled flag which is only set to true when UBI is sufficiently initialized. This means we now can have multiple works queued, so we can no longer simply do one work when queued, but instead have to continue to do work until all work is done. The best place to do so is a ubi_thread() function which behaves similar to the Kernel function with the same name, but is called synchronously in barebox. To make sure that the initially queued works are done, the call to (no-op) wake_up_process() at the end of ubi_attach_mtd_dev() is replaced with a call to ubi_thread(). While at it also honor the ubi->ro_mode flag to make sure we do not do any wear leveling work on readonly UBI devices. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * usb: imx-us-phy: implement notify_(dis)concectSascha Hauer2016-09-291-0/+27
| | | | | | | | | | | | | | | | | | | | | | The i.MX6 USB phy does not recognize disconnects of high speed devices when the USBPHY_CTRL_ENHOSTDISCONDETECT is not set. The phy does not work properly though when this bit is always set, so implement the notify_(dis)concect() callbacks to set this bit whenever a high speed device is connected and to clear it again when the device is disconnected.

| | | | | | | | | | | | | | | | | | Add a nop usb transcveiver driver. At the moment it does nothing, so is nothing more than a driver to satisfy the device tree dependencies. clk / vbus-regulator / vbus-detect-gpio support can be added later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * phy: Introduce to_usbphy conversion functionSascha Hauer2016-09-291-0/+12
| | | | | | | | | | | | | | | | | | | | The generic phy support layer has the necessary list handling and phy retrieval functions, so we should reuse them for usb phys. This adds a phy_to_usbphy() conversion function which drivers can implement which attach to the generic phy layer and are really usb phys. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * phy: Introduce of_phy_get_by_phandleSascha Hauer2016-09-291-0/+36
| | | | | | | | | | | | | | | | | | Currently generic phy support assumes that the standard phy binding from dts/Bindings/phy/phy-bindings.txt is used.

| |/ | | | | | | | | | | | | | | | | | | Currently we use a ioctl API to create/remove ubi volumes. This means we always have to carry all function code for ubi volume manipulation when the ioctl is compiled in.

The respective commit in Linux is: a526973e0291 ("pinctrl: mvebu: Fix mapping of pin 63 (gpo -> gpio)") which appeared in v4.1-rc3. The devicetrees are fixed accordingly since commit ce5cad51f381 ("ARM: dts: armada-370: Update the mpp63 function in the device tree on Armada 370") which appeared in v4.6-rc1. This fixes a runtime warning on the affected machines (globalscale-mirabox and netgear-rn104) and makes the pin functional again.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on kernel patch 0691bb1b5a1865b3bbc9b7ce6e26eff546abb1cf by Dinh Nguyen <dinguyen@altera.com>. The C0(mpu_clk), C1(main_clk), and C2(dbg_base_clk) outputs from the main PLL go through a pre-divider before coming into the system. These registers were hidden for the CycloneV platform, but are now used for the ArriaV platform. This patch updates the clock driver to read the div-reg property for the socfpga-periph-clk clocks. Note: The registers used for the div-reg property are not documented but set by the preloader.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the Linux kernel and the qemu code, the MMCIFIFOCNT contains the remaining number of words to read, excluding those that are already in the FIFO. So the current number of bytes in the FIFO is host_remain - (readl(base + MMCIFIFOCNT) << 2). Also writing to MMCIDATACTRL will reset the read counter. As a result, MCI_DATABLOCKEND is never set and read_bytes() waits forever. With this change, SD-Card support on qemu vexpress works correctly.
