| * | | | ARM: i.MX7: drop now useless imx7s.dtsiUwe Kleine-König2017-07-303-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file was introduced in commit 55eed47d8515 ("ARM: i.MX7: Add imx7s.dtsi") because the imx clocksource driver picked the wrong clock to determine the parent frequency. As this is fixed since commit "ARM: imx: clocksource: Use per clock for determining parent freq" this file can go away.

For imx6sl, imx6sx and imx6ul different clocks are returned, but both are gates for "perclk". For imx6qdl clk_get(..., NULL) returns IMX6QDL_CLK_GPT_IPG which is a gate of "ipg", while clk_get(..., "per") returns IMX6QDL_CLK_GPT_IPG_PER which is a gate of "ipg_per" which in turn is a divider of "ipg" with a boot-up default value of 1 which isn't touched in barebox. So the only SoC where this change matters is imx7 where clk_get(dev, NULL) returns a dummy clk while clk_get(dev, "per") returns the right clk to use.

If FILE was a relative path with the final component being a symbolic link, and all preceding paths being directories, the command sort of worked, but produced a relative path as the result. Both of these cases were broken by the above commit. Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Looks like we can get rid of an 'if' and 'goto', so do it to simplify the code.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the circular bucket meta magic was not found, it is assumed that the whole written state is in the old on-storage format. In that case, the size of the circular bucket meta must not be subtracted from the read length, or the (complete_len > len) check in the raw backend's verify function will fail: state: Error, invalid data_len 16 in header, have data of len 24 Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
* | | i.MX: clk-pllv3: Initially disable PLL_BYPASS bitPhilipp Zabel2017-07-121-0/+5

This causes the USB controller on i.MX6Q to run at bypass frequency and fail: barebox@Boundary Devices i.MX6 Quad Nitrogen6x Board:/ usb usb: USB: scanning bus for devices... usb: Bus 001 Device 001: ID 0000:0000 EHCI Host Controller imx-usb 2184200.usb: port(0) reset error This patch adds code to unconditionally disable the PLL_BYPASS bit initially, when the PLL clocks are registered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dma_alloc return non-coherent memory, but the driver does no cache maintenance on the buffer, causing memory corruption.
