| * | | 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.

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>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | In barebox_non_pbl_start() we do not run at the address we are linked at, so we must read linker variables using ld_var(). Since ld_var() current is not available on arm64 we create two zero sized arrays, one at the begin of the image and one at the end. The difference between both is the image size we are looking for.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | 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.
