* i.MX: vf610-twr: Remove MSCM setup codeAndrey Smirnov2017-01-121-5/+0
| | | | | | | | | Recent kernel versions should have appropriate driver code that sets up interrupt rounting correctly, so there's no need for that to be done in the bootloader. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* i.MX: imx-usb-phy: Add VF610 OF compatiblity stringAndrey Smirnov2017-01-121-0/+2
| | | | | | | | | | From looking at analogous Linux driver code it seems that all of the differences between code "imx23-usbphy" and "vf610-usbphy" pertain to suspend/resume functionality, which shouldn't affetct Barebox. As a result this commit just adds a compatiblity string and no other code. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | Mask ROM leaves the CPU running at 264Mhz, so configure the clock tree such that CPU runs at maximum supported frequency. Maximum supported frequncy is determined from speed grading burned into OCOTP fusebox by the vendor.

| | | | | | | | | | Add IMX_PLLV3_SYS_VF610 subtype to pllv3 code to be able to control and re-clock PLL1 and PLL2 on Vybrid SoC. This commit also introduces imx_clk_pllv3_locked which allows the user to create PLLv3 and specify how it should be polled for "locked" status (used in .set_rate callback) Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* i.MX: ocotp: Initialize OCOTP as early as possibleAndrey Smirnov2017-01-121-1/+1
| | | | | | | | | On Vybrid SoC OCOTP module contains speed grading information that is needed to correctly adjust CPU clock to its maxumum rate, so we need to have this information handy as early as possible.

* i.MX: ocotp: Add provisions for storing multiple MAC addressesAndrey Smirnov2017-01-121-19/+51
| | | | | | | | | | | | i.MX SoC variants like Vybrid have more than one built-in Ethernet interface and as a consequence support storing more than one MAC address in OCOTP module. Add code to create multiple 'mac_addr<n>' parameters as well as 'mac_addr' as an "alias" to 'mac_addr0' for backwards compatibility.

| * i.MX: ocotp: Account for shadow memory gapsAndrey Smirnov2017-01-111-3/+31
| | | | | | | | | | | | | | | | | | | | Shadow memory does not have a true 1:1 mapping to fuse address space. All i.MX6 devices, with exception of i.MX6SL have a 0x100 byte gap between banks 5 and 6 (or addresses 0x2f and 0x30), so we need to account for that when reading data from shadow memory.

| * i.MX: esdhc: Request "per" clock explicitlyAndrey Smirnov2017-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling clk_get() with NULL as the second argument will give us "ipg" clock as a result. The actual clock feeding into the peripheral is "per" and, depending on the SoC, "ipg" and "per" may be separated by a clock divider, so querying "ipg"'s rate may not result in rate that does not represent the actual peripheral clock rate. Change the code to request "per" as our peripheral clock to avoid aforementioned problem. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * i.MX: esdhc: Do not rely on CPU type for quirksAndrey Smirnov2017-01-111-21/+100
| | | | | | | | | | | | | | | | | | | | | | | | CPU type is not a reliable indicator of the underlying type of IP core used, since there's no 1:1 mapping between the two. As example of one such violation consider Vybrid SoC which contains IP block from i.MX53. Instead port feature flags from corresponding Linux kernel driver and use the ones that are relevant.
